THE HUMAN MIRACLE

     OF ALL the marvelous things on earth, none is more astounding than the human brain. For example, every second some 100 million bits of information pour into the brain from the various senses. But how can it avoid being hopelessly buried by this avalanche? If we can think about only one thing at a time, how does the mind cope with these millions of simultaneous messages? Obviously, the mind not only survives the barrage but handles it with ease.

 How it does so is only one of the many wonders of the human brain. Two factors are involved. First, in the brain stem there is a network of nerves the size of your little finger. This network is called the reticular formation. It acts as a kind of traffic control center, monitoring the millions of messages coming into the brain, sifting out the trivial and selecting the essential for attention by the cerebral cortex. Each second this little network of nerves permits only a few hundred, at most, to enter the conscious mind.

 Second, a further pinpointing of our attention seems to come about by waves that sweep the brain 8 to 12 times per second. These waves cause periods of high sensitivity, during which the brain notes the stronger signals and acts upon them. It is believed that by means of these waves the brain scans itself, in this way focusing on the essentials. Thus an amazing flurry of activity is going on in our heads every second!

Something “to Wonder At”

  In recent years scientists have made tremendous strides in studies of the brain. Even so, what they have learned is nothing compared to what remains unknown. One researcher said that, after thousands of years of speculation and recent decades of intensive scientific research, our brains, along with the universe, remain “essentially mysterious.”  Certainly the human brain is easily the most mysterious part of the human miracle—“miracle” meaning something “to wonder at.”

 The wonder begins in the womb. Three weeks after conception brain cells start forming. They grow in spurts, at times up to 250,000 cells a minute. After birth the brain continues growing and forming its network of connections. The gulf separating the human brain from that of any animal quickly manifests itself: “The brain of the human infant, unlike that of any other animal, triples in size during its first year,” states the book The Universe Within.  In time, about 100 billion nerve cells, called neurons, as well as other types of cells, are packed into a human brain, although it makes up only 2 percent of the body’s weight.

 The key brain cells—the neurons—do not actually touch one another. They are separated by synapses, tiny spaces less than one millionth of an inch across. These gaps are bridged by chemicals called neurotransmitters, 30 of which are known, but the brain may possess many more. These chemical signals are received at one end of the neuron by a maze of tiny filaments called dendrites. The signals are then transmitted at the other end of the neuron by a nerve fiber called an axon. In the neurons the signals are electrical, but across the gaps they are chemical. Thus the transmission of nerve signals is electrochemical in nature. Each impulse is of the same strength, but the intensity of the signal depends upon the frequency of the impulses, which may be as high as one thousand a second.

  It is not certain just what physiological changes take place in the brain when we learn. But experimental evidence suggests that as we learn, especially in early life, better connections are formed, and more of the chemicals bridging the gaps between neurons are released. Continued use strengthens the connections, and thus learning is reinforced. “Pathways that are often activated together are strengthened in some way,” reports Scientific American.  Interesting on this point is the Bible’s comment that deeper matters are more easily understood by mature people “who through use have their perceptive powers trained.” (Hebrews 5:14) Research has revealed that unused mental powers fade away. Thus the brain, like a muscle, is strengthened by use and weakened by disuse.

  The vast numbers of microscopic nerve fibers making these connections within the brain are often referred to as its “wiring.” They are precisely placed within a maze of staggering complexity. But how they are placed in the exact spots called for by the “wiring diagrams” is a mystery. “Undoubtedly the most important unresolved issue in the development of the brain,” one scientist said, “is the question of how neurons make specific patterns of connections. . . . Most of the connections seem to be precisely established at an early stage of development.”  Another researcher adds that these specifically mapped-out areas of the brain “are common throughout the nervous system, and how this precise wiring is laid down remains one of the great unsolved problems.”

  The number of these connections is astronomical! Each neuron may have thousands of connections with other neurons. Not only are there connections between neurons, but there are also microcircuits that are set up directly between the dendrites themselves. “These ‘microcircuits,’” says one neurologist, “add a totally new dimension to our already mind-boggling conception of how the brain works.”  Some researchers believe that the “billions upon billions of nerve cells in the human brain make perhaps as many as a quadrillion connections.”  With what capacity? Carl Sagan states that the brain could hold information that “would fill some twenty million volumes, as many as in the world’s largest libraries.”

  It is the cerebral cortex of the brain that sets man far apart from any animal. It is less than a quarter of an inch thick, and it forms a fissured mold snug against the skull. If laid out, the cortex would measure about two and a half square feet, with some ten thousand miles of connecting fibers per cubic inch. The human cortex not only is far bigger than that of any animal, but it also has a much larger uncommitted area. That is to say, it is not committed to handling the physical functions of the body but is free for the higher mental processes that separate people from animals. “We are not just smarter apes,” one researcher said. Our minds “make us qualitatively different from all other forms of life.”

Our Far Greater Capability

  “What distinguishes the human brain,” a scientist said, “is the variety of more specialized activities it is capable of learning.” Computer science uses the term “hardwired” to refer to built-in characteristics based on fixed circuitry, in contrast to functions put into a computer by a programmer. “Applied to human beings,” one authority writes, “hard wiring refers to innate abilities or, at least, predispositions.”  In people there are many built-in capacities for learning, but not the learning itself. Animals, by contrast, have hardwired instinctive wisdom, but limited capacities to learn new things.

  The Universe Within notes that the most intelligent animal “never develops a mind like that of a human being. For it lacks what we have: preprogramming of our neural equipment that enables us to form concepts out of what we see, language out of what we hear, and thoughts out of our experiences.” But we must, by input from our surroundings, program the brain, otherwise, as the book states, “nothing resembling the human mind would develop . . . Without that immense infusion of experience, scarcely a trace of intellect would appear.”  So the capability that is built into the human brain enables us to construct the human intellect. And, unlike animals, we have the free will to program our intellects as we choose, based on our own knowledge, values, opportunities and goals.

Language Unique to Humans

 An outstanding example of hardwired capabilities with great flexibility for programming by us is language. Specialists agree that “the human brain is genetically programmed for language development,” and that speech “can be explained only on the basis of an innate language-processing capacity within our brain.”   Unlike the rigidity that is displayed in the instinctive behavior of animals, however, there is tremendous flexibility in a human’s use of this hardwired capacity for language.

  A specific language is not hardwired into our brains, but we are preprogrammed with the capacity for learning languages. If two languages are spoken in the home, a child can learn both. If exposed to a third language, the child can learn it also. One girl was exposed to a number of languages from babyhood. By the time she was five she spoke eight fluently. In view of such innate abilities it is no surprise that a linguist said that chimpanzee experiments with sign language “actually prove that chimps are incapable of even the most rudimentary forms of human language.”

  Could such an amazing ability have evolved from the grunts and growls of animals? Studies of the most ancient languages rule out any such evolution of language. One specialist said that “there are no primitive languages.” Anthropologist Ashley Montagu agreed that so-called primitive languages “are often a great deal more complex and more efficient than the languages of the so-called higher civilizations.”

  One neurologist concludes: “The more we attempt to investigate the mechanism of language, the more mysterious the process becomes.” Another researcher says: “At present the origin of syntactic speech remains a mystery.”  And a third states: “The power of speech, moving men and nations as no other force, uniquely sets humans apart from animals. Yet, the origins of language remain one of the brain’s most baffling mysteries.”  It is no mystery, however, to those who see in it the hand of a Creator who “hardwired” areas in the brain for language capabilities.

Things Only Creation Can Explain

  The Encyclopædia Britannica states that man’s brain “is endowed with considerably more potential than is realizable in the course of one person’s lifetime. “ It also has been stated that the human brain could take any load of learning and memory put on it now, and a billion times that! But why would evolution produce such an excess? “This is, in fact, the only example in existence where a species was provided with an organ that it still has not learned how to use,” admitted one scientist. He then asked: “How can this be reconciled with evolution’s most fundamental thesis: Natural selection proceeds in small steps, each of which must confer on its bearer a minimal, but nonetheless measurable, advantage?” He added that the human brain’s development “remains the most inexplicable aspect of evolution.” Since the evolutionary process would not produce and pass on such excessive never-to-be-used brain capacity, is it not more reasonable to conclude that man, with the capacity for endless learning, was designed to live forever?

  Carl Sagan, amazed that the human brain could hold information that “would fill some twenty million volumes,” stated: “The brain is a very big place in a very small space.”  And what happens in this small space defies human understanding. For example, imagine what must be going on in the brain of a pianist playing a difficult musical composition, with all fingers flying over the keys. What an astonishing sense of movement his brain must have, to order the fingers to strike the right keys at the right time with the right force to match the notes in his head! And if he hits a wrong note, the brain immediately lets him know about it! All this incredibly complex operation has been programmed into his brain by years of practice. But it is made possible only because musical capability was preprogrammed into the human brain from birth.

  No animal brain ever conceived such things, much less is able to do them. Nor does any evolutionary theory provide an explanation. Is it not evident that man’s intellectual qualities mirror those of a Supreme Intellect? This harmonizes with Genesis 1:27, which states: “God proceeded to create the man in his image.” The animals were not created in God’s image. That is why they do not have the capabilities man has. Though animals do amazing things by predetermined, rigid instincts, they are no match at all for humans with their flexibility in thinking and acting and their ability to continually build on previous knowledge.

  The human capacity for altruism—unselfish giving—creates another problem for evolution. As one evolutionist noted: “Anything that has evolved by natural selection should be selfish.” And many humans are selfish, of course. But as he later acknowledged: “It is possible that yet another unique quality of man is a capacity for genuine, disinterested, true altruism.”  Another scientist added: “Altruism is built into us.”  Only in humans is it practiced with an awareness of the cost, or sacrifice, that may be involved.

Appreciating the Human Miracle

  Just consider: Man originates abstract thinking, consciously sets goals, makes plans to reach them, initiates work to carry them out and finds satisfaction in their accomplishment. Created with an eye for beauty, an ear for music, a flair for art, an urge to learn, an insatiable curiosity, and an imagination that invents and creates—man finds joy and fulfillment in exercising these gifts. He is challenged by problems, and delights in using his mental and physical powers to solve them. A moral sense to determine right and wrong and a conscience to prick him when he strays—these too man has. He finds happiness in giving, and joy in loving and being loved. All such activities enhance his pleasure in living and give purpose and meaning to his life.

  A human can contemplate the plants and animals, the grandeur of the mountains and oceans around him, the vastness of the starry heavens above him, and feel his smallness. He is aware of time and eternity, wonders how he got here and where he is going, and gropes to understand what is behind it all. No animal entertains such thoughts. But a human seeks the whys and wherefores of things. All of this results from his being endowed with an awesome brain and his bearing the “image” of the One who made him.

  With amazing insight, the ancient psalmist David gave credit to the One who designed the brain and whom he considered to be responsible for the miracle of human birth. He said: “I shall laud you because in a fear-inspiring way I am wonderfully made. Your works are wonderful, as my soul is very well aware. My bones were not hidden from you when I was made in secret, when I was woven in the lowest parts of the earth. Your eyes saw even the embryo of me, and in your book all its parts were down in writing.”—Psalm 139:14-16.

  Truly, it can be said that the fertilized egg in the mother’s womb contains all the parts of the emerging human body “down in writing.” The heart, the lungs, the kidneys, the eyes and ears, the arms and legs, and the awesome brain—these and all the other parts of the body were ‘written down’ in the genetic code of the fertilized egg in the mother’s womb. Contained in this code are internal timetables for the appearance of these parts, each one in its proper order. This fact was recorded in the Bible nearly three thousand years before modern science ever discovered the genetic code!

  Is not the existence of man with his amazing brain truly a miracle, a cause for wonderment? Is it not also evident that such a miracle can be accounted for only by creation, not evolution?

BEAUTY IN THE AIR


HER fine silky hair bouncing in the breeze, the little girl pursues her “prey”—a lovely, delicate butterfly. Joining in her little game, the butterfly obligingly alights on this flower and that. Then, as if to tease, it flies away just as the tiny cupped hands are about to capture it. Suddenly, our little friend has an idea: Instead of noisily scrambling after the elusive butterfly, she slowly and quietly approaches it as it rests on a pretty wildflower. Wide-eyed, she is rewarded with a wonderful close-up view of one of the most colorful of God’s creations.

Shall we join her? Our own appreciation of this winged masterpiece will also grow.

Look Closely

See the three basic body sections? (See page 18.) First, there is the head with its characteristic pair of clubbed antennae. These aid the senses of smell, touch, and perhaps even hearing. They help the butterfly locate its favorite food or a mate. Also, we note two large compound eyes capable of panoramic sight in full color. Can you see what looks like a tube rolled up and tucked under its head? This long tongue is called a proboscis. It uncoils to enable the butterfly to sip sweet nectar from flowers or taste other favorite foods.

The midsection of the body is called the thorax. Four lovely wings are attached here. The vibrant colors and intricate patterns that we see are actually produced by hundreds of tiny scales, each connected to a socket on the wing. These colored plates contain air, which makes the wing lightweight and acts as an excellent insulator for temperature control.

Three pairs of legs are also connected to the thorax. The legs have bristles that help many butterflies to respond to sounds.

Adult butterflies also have ‘taste buds’ on their feet. Researchers have found that when a butterfly’s feet touch something sweet, the tongue automatically uncoils, ready to feed. The North American monarch butterfly has taste organs in its feet that are 2,000 times more sensitive than the human tongue!

The last major body division is the abdomen, which contains the digestive system and the reproductive organs. Look closely at the segments of the abdomen, and you’ll see little holes through which a butterfly breathes. These are called spiracles.

A Master of Change

The butterfly we observe poised on the flower has not always been as delicate or as graceful. It has experienced some rapid and dramatic changes in form. This process of development is called complete metamorphosis. Drastic changes take place between the different stages of the one living organism.

Depending on the kind of butterfly, life begins as a tiny egg laid on the leaf of a plant that will be eaten by the larva—or better known by its other name, caterpillar—when it hatches. Some eggs may develop into caterpillars within three short days. Other eggs laid in the fall will pass the winter before hatching.

Once free of its eggshell home, the hungry caterpillar proceeds to devour the empty shell. Then it turns its attention to the host plant. The little creature is a virtual eating machine as it gorges itself to store up enough food to last through the lean days ahead. Butterfly specialists claim that if a six-pound human baby would gain weight at the same rate as caterpillars, at the end of two weeks the baby would tip the scales at eight tons!

Inevitably, as the caterpillar satisfies its voracious appetite, its body expands, and it literally outgrows its skin. Typically, a caterpillar will split and shed its skin four or five times before entering into its third stage of development—the pupa stage.

This most fascinating caterpillar molt begins when the full-grown larva attaches itself to a surface with a silken lifeline. In an aerial act that would amaze most circus performers, the caterpillar sheds its outer skin to reveal a pupal shell beneath. All the furious eating comes to a halt. The pupa, or chrysalis, may now look inactive or even dead, but inside an incredible transformation is taking place that will change the larva into a beautiful butterfly.

Hormones cause most of the larval organs to dissolve, and the resulting fluids and materials rearrange to form the adult inside the pupa.

Warm temperatures, adequate length of daylight, and moisture signal the developed butterfly inside that the time is right to emerge. The chrysalis splits open as the winged beauty struggles to get free, taking anywhere from 90 seconds to 5 minutes. The newly hatched butterfly hardly looks fit to make its debut. Its cramped quarters have left its wings wet and crumpled. So, clinging where it has emerged, it pumps body fluids in the veins of the wings, which expand and begin to harden. Its life may span from three days up to eight months or even a year.

In Search of Butterflies

Should you care to journey to the arid southwestern deserts of the United States, you might be delighted to spot the Felders’ orange-tip (Anthocharis cethura). How does it cope with such an unfriendly climate? It flies only during the early spring months in years when enough rainfall has produced its desired food plants. The patient pupae may delay hatching up to five or six years, waiting for the right amount of moisture.

These deserts also host another butterfly of distinction: the giant skipper (Megathymus coloradensis). This large butterfly has a chunky body and comparatively small triangular wings that make it look as if flight would be awkward. Don’t be fooled—these jets of the insect world may be the fastest butterflies on earth, with speeds of 60 miles per hour [96 km/hr].

Traveling to the cold windswept summits of the California Sierra Nevadas, we would find the hardy ivallda arctic (Oeneis ivallda). It withstands winters lasting nine to ten months at elevations of 10,000-14,000 feet [3,000-4,000 m]. How does it survive? Scientists believe that the caterpillar is able to produce its own “antifreeze.”

Perhaps you would enjoy observing the large blue (Maculinea arion) of Europe and its partnership with the ants. After several molts, it is found by certain kinds of ants, which stroke a “honey gland” on the back of the caterpillar, yielding a sweet fluid. The ants adopt the caterpillar, carrying it back to their nest, where they give it ant larvae to eat in exchange for the sweet “honeydew.” Eventually, the caterpillar enters the pupa stage, emerging as a butterfly three weeks later.

Within the butterfly world we find tremendous variety in size, wing shape, color, and patterns. In some cases, though, the opposite is true. Some species so resemble each other that only experts can accurately identify them. Several poisonous kinds afford protection to their nonpoisonous look-alikes, as wary birds and other predators have learned not to make a meal of them. The smallest known butterfly specimen, pygmy blue (Brephidium exilis) of North America, is less than one half inch [1 cm] in wingspan. The largest is the Queen Alexandra’s birdwing (Ornithoptera alexandrae) of the South Pacific, which can have a wingspread of 11 inches [28 cm].

About 10,000 to 20,000 different species of butterflies adorn the surface of this planet. They are to be found braving the harsh desert heat of North Africa; scaling the dizzying heights of the Himalayas to altitudes of 20,000 feet [6,000 m]; living more than 100 feet [30 m] below sea level in the Middle East and Death Valley, California; playing about the tropical rain forests of South America, Africa, and Asia; patrolling the turbulent Atlantic seacoasts; and even surviving in the frigid tundra above the Arctic Circle.

In a flash of color, the butterfly we were watching at the outset is once again airborne, bound for parts unknown.

ALLIGATORS---RARE, WHITE, AND BLUE-EYED!


THE following release prepared by Curt Burnette for Audubon Institute tells the story of the remarkable white alligators.

“The white-skinned, blue-eyed alligators are a genetic mutation of the American alligator and not a different species. This mutation is called leucism, therefore these are leucistic alligators. Albinos have white skin and pinkish-yellow eyes. Leucistic animals have pigmented eyes. Albinism is rare but leucism is even more rare. Although leucism is known in a few other species of animals, the white gators are the first known leucistic alligators.

“There are 18 white gators, all discovered at the same nest site in late August, 1987. Three Cajun fishermen found them near Houma, Louisiana, southwest of New Orleans. They were approximately 1-2 weeks old when the first ones were brought to the Audubon Zoo on September 5, 1987. Besides the 18 whites, 7 normal-colored siblings were captured and an undetermined number of normals escaped. The nest was located on land owned by the Louisiana Land and Exploration Company (LL&E). Although the nest area has been watched and eggs collected and hatched out, no further white gators have ever been discovered.

“All 18 white gators and their 7 normal siblings are male. This is possible because the sex of a baby alligator is determined by the temperature of the nest and so can be all male, all female, or a mix. As of this writing, the gators are reaching sexual maturity (5-6 years). The size of the 18 varies from about 5 feet and 50-60 pounds to over 8 feet and 250 pounds. This is a result of differing management techniques. Gators raised at LL&E’s alligator farm grow more rapidly.

“LL&E owns 14 of the white gators and graciously donated 4 to the Audubon Institute. The Institute currently displays 2 at its Audubon Zoo and 2 at its Aquarium of the Americas. Two alligators are rotated out on loan to other zoos and aquariums and have already been to over a dozen in the U.S. and one in Japan.

“The white gators have become famous and popular all over the world. Their discovery was broadcast worldwide by CNN. They have made numerous television appearances including the Today Show, the Nashville Network, the Tonight Show, CBS Morning News, Late Night with David Letterman, Christian Broadcast Network, MTV, and various foreign news and morning shows. Newspaper and magazine articles worldwide occasionally feature them. A few years back a French magazine ran an article and photos of them and the public response was so favorable they ran a sequel feature.

“How come there are so few white gators and no one had ever seen any before? Besides being rare mutations to begin with, leucistic and albinistic alligators are at a distinct and deadly disadvantage from normal alligators. When a baby gator hatches, it’s only 8-10 inches long. The mother gator guards the nest for a while but soon the little gators are on their own. Normal gator hatchlings are yellow and black striped and blend in well with their surroundings. A white hatchling would easily be spotted by and fall prey to many different predators.

“Two last interesting and unusual facts about the white gators: their black spots and their temperament. Only a very few of the white gators were hatched with black spots. Most had none at all. As they grew, however, more began developing some black areas. Almost all the spots developed around the head and neck only. It has made it easier to identify who is who, although some have never acquired any spots at all.

“And finally, it is agreed by everyone who has worked with the white gators, they are more feisty and temperamental than normal alligators. No one is sure why this is so, but they are treated as if they were fast and quick-tempered crocodiles rather than relatively slower and more easygoing alligators. Yet another of the many mysteries that surround these white wonders of the swamp!”—By Curt Burnette, Audubon Institute.

CULTIVATING ORCHIDS---HOW PATIENCE PAYS OFF


  .                 
GROWING orchids can be habit-forming. Some admirers spend hours studying the Latin names of their favorites so they can pronounce them properly. Why are people so fascinated with orchids?

The number of different kinds of orchids is vast. Some 25,000 different species have been discovered in the wild, and official organizations recognize more than 100,000 artificial hybrids! The label “artificial hybrid” does not mean that botanists have created new living organisms from soil, water, and air. Rather, such hybrids are the product of controlled cross-pollination.

Naturally occurring orchids as well as those produced with human assistance come in a variety of sizes. There are tiny orchids that are best observed with a magnifying glass, while others display themselves nicely on a windowsill. One orchid that grows in the Indonesian rain forest can weigh over 1,000 pounds [500 kg]!

Orchids flaunt a rainbow of colors and come in many shapes. Some of them bear a striking resemblance to bees, moths, and birds, while others with forms unlike anything you have ever seen before are particularly captivating, especially to breeders. For many years, only the rich could acquire these beautiful plants, but now orchids are available to those of lesser means. Here is the story behind the beautiful orchids you can enjoy today.

The “Orchid Rush”

People have admired orchids for centuries, but only in fairly recent times have growers learned effective ways to reproduce them. In 1856 the first man-made orchid hybrid flowered. However, cultivating these splendid but fussy flowers was often more tedious than delightful.

Orchid seeds are small—some are like fine dust. Handling such tiny seeds was, and often still is, a challenge, but the greatest difficulty has been getting them to grow. For decades, growers experimented with different materials and conditions to find the right medium for the germination of orchid seeds. In 1922, Dr. Lewis Knudson, a scientist at Cornell University in the United States, discovered that when the seeds were placed in a mixture of water, sugar, and agar (a jellylike substance extracted from seaweed), they sprouted and flourished. Soon enthusiasts were producing new orchid hybrids in abundance. This “orchid rush” continues, with many hybrids never before seen in public appearing each year.

But long before humans cultivated them, orchids grew in the wild. How do orchids produce hybrids in their natural environment?

Orchids in the Wild

When two or more closely related orchid species are flowering in the same area, there is a chance that a natural hybrid will develop. In nature, insects and other creatures act as pollinators. When a pollinator visits orchids in search of nectar, pollen from one plant sticks to its body and pollinates subsequent plants visited. The pollinated orchids may then become fertilized. As such, they will produce seedpods.

In time, the seedpod ripens, splits open, and sets loose thousands, or even millions, of seeds. Some of these fall to the ground, while the wind carries off many others. The seeds that take root have a hard time, and very few reach maturity. Those that grow as a result of pollen from one species fertilizing another species are known as natural hybrids. But how is an artificial orchid hybrid made?

Making the Hybrid

An orchid hybrid is the combination of characteristics from each of its parents. Hence, a grower first considers what kind of flower he wishes to produce. He may be looking for a certain color or stripes or spots. He may be seeking to combine those features in a plant with small flowers or large ones. Fragrance is another factor. With those points in mind, the grower selects two orchids that will hopefully endow their offspring with the desired characteristics. For instance, an orchid cultivator may choose the golden slipper orchid (Paphiopedilum armeniacum) as one of the species he will use. That orchid was discovered in China in 1979. It often imparts a rich golden-yellow to its hybrid offspring, some of which are stunningly beautiful.

Once the grower has acquired his two parent plants, he removes all existing pollen from the pod parent, the flower that will receive pollen from the other plant. The orchid that supplies the pollen is known as the pollen parent. With a toothpick or similar tool, the grower removes pollen from the pollen parent and smears the pollen at the base of the column of the flower of the pod parent. He labels this cross-pollinated orchid with the names of both parents and the pollination date.

Patience Is a Must

If fertilization takes place, an amazing thing occurs in the blossom of the pod parent. Threadlike tubes stretch out from the column to a part of the blossom known as the ovary. The ovary then swells and forms a seedpod. Inside, hundreds of thousands of tiny seeds are forming, each one connected to a single pollen tube. It may take months or more than a year for the seedpod to ripen. At that point, the grower gathers the seeds from the seedpod. He places them in a sterilized flask with a solution of agar and nutrients. If the seeds germinate, tiny orchids will soon appear like a carpet of green grass.

After a few months, the grower removes the seedlings from the flask and places them close together in a community pot. He keeps an eye on the seedlings, frequently watering them so they will not dry out. In time, the grower transplants his new orchids to individual pots. At this point, patience is a true virtue. Orchids may take from a few years to over a decade to bloom.

Imagine a grower’s satisfaction when he sees a blossom on an orchid he has worked to produce! If the hybrid is new, the grower can register it using a name of his choosing. All hybrids developed thereafter using that genus/species blend will thus be referred to by the registered name.

At times, a grower finds an ideal combination that creates a sensation among orchid hobbyists. He may receive awards, and his beautiful plants will command high prices. But regardless of the monetary outcome, the pleasure of seeing a blossom on an orchid that he has crossed is a delight.
Now you know that it took much time and patience to produce the beautiful orchids that you admire. But in reality, the work humans do in producing orchid hybrids is simple compared with that of the grand Creator of every living thing, Jehovah. He has put the complex genetic code in each plant, allowing for such gorgeous blossoms. We are merely the recipients of his artistic love demonstrated among the fascinating variety of orchid hybrids. It is truly as the psalmist David wrote: “How many your works are, O Jehovah! All of them in wisdom you have made. The earth is full of your productions.”—Psalm 104:24

AWESOME BEAUTY AND GRACE


 

I quickly fell in love with horses. They are so beautiful and boast a unique gracefulness.”—TOMASZ, AN EXPERT HORSE BREEDER.

MANY regard horses as the most beautiful of animals, favored for their grace and their unbridled energy as they rear up on their hind legs, pound the ground with their hooves, snort proudly, and charge forward courageously. They truly are a thing of beauty.

Over the centuries, across a variety of climatic zones and diverse terrains, numerous breeds of horses have been developed. The purebred Arabian horse is viewed as one of the most handsome of breeds. It is classed as hot-blooded, with energy, speed, stamina, and intelligence that make it good for use in sports.

Interestingly, Poland, a Central European country, enjoys a rich tradition of breeding these spirited steeds. In the eyes of breeders and experts alike, some of the most valuable Arabians with the best of bloodlines have links with Poland. Why is that? This and other questions have been put to horse breeders and authorities in the field.

How Enthusiasts View the Breed

To begin with, let us find out a bit more about the purebred Arabian. This breed has always been associated with the Middle East. Tomasz, an expert horse breeder, explains: “For centuries Bedouin tribes cultivated and preserved the purity of the Arabian horse. Thanks to strict selection and the painstaking care of the breeders, the prized Arabian breed was created. Most commonly, these horses are gray, bay, or chestnut in color; occasionally they are black.”

Żaneta, an Arabian fancier, says, “They are extraordinarily beautiful and are thought to be the purest and oldest of all horse breeds.” They are known not only for their fiery temperament but also for their courage and stamina. The Arabian’s strong lungs—encased in its broad, deep chest—make it ideal for long-distance riding.

From Arabia to Poland

“How did Arabians actually get to Poland?” we ask Tomasz, who owns a stud farm here. “They may have first come in the company of an emissary of the king, who was returning from one of his numerous trips to the 16th-century sultanic court of Stambul,” he explains. “What is beyond any doubt, though, is that the Polish breeding program dates back to the late 18th century.” Izabela Pawelec-Zawadzka, an expert Arabian-horse breeder, highlights the role of a certain Count Wacław Rzewuski. As an authority on Oriental culture, he “became the instigator and organizer of import expeditions to bring horses from Arabia,” bringing 137 purebred horses to Europe.

Rzewuski’s persistence and zeal led to the founding of the first Polish Arabian stud farm in Janów Podlaski, East Poland, in the year 1817. “The beginnings looked promising. Qualified breeders looked after the horses,” explains Tomasz. “But the two world wars, which raged throughout the heart of Europe, wreaked havoc on the Polish stud farms. The majority of the horses died, ran away, or were rustled.” However, some time after the second world war, the breeding program was successfully resumed.

The Arabians are now raised in at least 30 Polish stud farms. Two hundred years of tradition guarantees the best-quality horses. Poland has thus become one of the most prominent centers for Arabian-horse breeding, attracting experts and enthusiasts in droves from all over the world to the prestigious annual shows and auctions.

Day-to-Day Care of the Arabian

Raising high-quality horses with distinguished pedigrees requires that breeders provide well for the needs of the animals. Małgorzata, another stud-farm owner, explains: “The care of the Arabian is a complex matter. We need to provide a balanced feeding program appropriate to the hot-blooded horse in order to maintain its levels of fitness and its good looks. Heavily pregnant mares require special attention.” What kind of feed is best for the Arabian?

Małgorzata continues: “We start the day by feeding the horses hay, which provides all the nutrition necessary, including essential vitamins and minerals. Oats mixed with chaff or cut straw are especially nutritious; barley and wheat bran are also good. But the horses actually prefer juicy green fodder—grass or alfalfa as well as potatoes, carrots, and beetroot. In winter, breeders often buy ready-mixed fodder rich in protein. As part of their diet, Arabians also need salt licks—lumps of salt containing minerals or herbs that cool down their fiery temper. It has to be said, though, that even the best hay or fodder is no match for a grassy pasture. And one last thing, the horses need to have access to clean water at all times—they will not touch dirty water.”

Proper care of the Arabian includes giving unfailing attention to its hide and hair. That calls for careful cleaning, gentle massaging with special brushes, and stroking by hand. There is more, though, as Tomasz explains: “Daily cleaning of the hooves is crucial, as it prevents various types of disease, including cancer. We have to be especially vigilant when it comes to the horse’s eyes, nostrils, lips, and ears.” Żaneta adds: “In order for the horse to be fit and to look elegant, it needs room to run and also sand, mud, or grass to roll in. When a horse perspires after trotting or galloping, it must be covered with a blanket and then cleaned afterward.”

Experts stress the importance of being sensitive to the specific needs of each horse. Małgorzata puts it this way: “It is believed that Arabians have a sixth sense—they value human company, being touched and embraced. Such human expressions build the horse’s trust in its rider to the point that it becomes completely devoted to that person. They are known to neigh with glee in response to a smile, an embrace, or a special treat—such as a carrot or a piece of sugar. Those who love horses have real fun looking after them.” Tomasz describes his passion for them: “I quickly fell in love with horses. They are so beautiful and boast a unique gracefulness. But earning their trust is not easy. It took me many years.”

The Future of the Horse

From time immemorial, people have been thrilled at the sight of the beauty, speed, agility, strength, and intelligence of horses, especially the Arabian breed, and have forged a unique bond with them. Sadly, that same bond has been exploited to vile ends in wars, during which hundreds of horses breathed their last. Under the rule of God’s Kingdom, however, people will use horses for only honorable purposes—all to the praise of their Creator, Jehovah God.

DOES GOD CARE ABOUT THE ANIMALS?



ANIMAL life is in peril. Many scientists believe extinction of animal species is taking place at an accelerated rate. Animals are suffering the devastating consequences of human encroachment. Industrial food production, cruel blood sports, and callous abandonment of pets add to this grim picture.

Some feel, however, that such a picture is the inevitable price of human progress. But is that what God intended? Has he abandoned animal creation to suffer at the hands of humans? How do we know that God cares about animals?

Care Evident From the Start

After God’s creation of fish, birds, and land animals, God was pleased. The Bible says that he “got to see that it was good.” (Genesis 1:21, 25) All those creatures, from the smallest to the largest, had the Creator’s loving concern. God not only created them “instinctively wise” but also made provisions for them to flourish in their environment. As a Bible writer aptly stated: “All of them—for you they keep waiting to give them their food in its season. What you give them they pick up. You open your hand—they get satisfied with good things.”—Proverbs 30:24; Psalm 104:24, 25, 27, 28.

True, God made animals subject to the first man, Adam. They were not designed with reasoning ability or the capacity for spirituality. (2 Peter 2:12; Jude 19) In contrast, Adam was a higher life-form, created “in God’s image.” He was able to reflect the personality of his Creator, Jehovah. (Genesis 1:27; Psalm 83:18) But this did not give humans license to exercise authority over animals independent of their Creator.

For example, Adam began naming the animals because Jehovah extended that privilege to him. Moreover, Jehovah assisted Adam by “bringing [the animals] to the man to see what he would call each one.” (Genesis 2:19) Only by working under his Creator’s direction could man be successful in caring for the animals.

God Really Does Care!

Sadly, Adam rebelled against his Creator. His rebellion brought devastating consequences to the human family and to all life on earth. The Creator, however, made clear how animals were to be treated. Although man was eventually permitted to use them for food and other practical purposes, God never sanctioned cruel treatment of them. The Bible says: “The righteous one is caring for the soul of his domestic animal, but the mercies of the wicked ones are cruel.”—Proverbs 12:10.

God even gave the ancient nation of Israel laws that addressed the welfare of animals. The arrangement for a Sabbath, a day of complete rest each week, benefited the Israelites’ animals in that they too could rest. (Exodus 23:12) Significantly, although no work was allowed on this sacred day, people were to come to the aid of a distressed animal. (Luke 14:5) God further directed that cattle were not to be deprived of food while they worked, and animals were not to be put under an extreme burden. (Exodus 23:5; Deuteronomy 25:4) Yoking a bull and a donkey together was prohibited, preventing injury to either animal. (Deuteronomy 22:10) Clearly, the Bible teaches that animals were to be treated with propriety, respect, and compassion!

Though many people focus on their own concerns and ignore any consequences to animals, God compassionately considers them. When the prophet Jonah reacted unmercifully when the inhabitants of Nineveh repented and were spared God’s judgment, Jehovah stated: “For my part, ought I not to feel sorry for Nineveh the great city, in which there exist more than one hundred and twenty thousand men who do not at all know the difference between their right hand and their left, besides many domestic animals?” (Jonah 4:11) Yes, the Creator felt pity even for the animals!

Future Care Is Assured

Clearly, God is not insensitive to how animals are treated. His beloved Son, Jesus, even said that a single sparrow does not fall to the ground without his Father’s knowledge. (Matthew 10:29) In contrast, even with the best of intentions, humans do not fully understand how their actions influence the environment. Managing human society in a way that shows regard for wildlife requires a change in mankind’s thinking.

Happily, the Bible describes the time when under God’s Kingdom rule, “the earth will certainly be filled with the knowledge of Jehovah.” (Isaiah 11:9) Such knowledge will provide obedient humans with the education and training they need to manage the earth properly. The Creator’s influence will then ensure that harmony prevails between man and beast, thus restoring the conditions on earth that God originally purposed.

The Bible describes the transformation that will then take place, explaining: “The wolf will actually reside for a while with the male lamb, and with the kid the leopard itself will lie down, and the calf and the maned young lion and the well-fed animal all together; and a mere little boy will be leader over them. And the cow and the bear themselves will feed; together their young ones will lie down. And even the lion will eat straw just like the bull. And the sucking child will certainly play upon the hole of the cobra; and upon the light aperture of a poisonous snake will a weaned child actually put his own hand.” What a glorious prospect to contemplate!—Isaiah 11:6-8.

FACE TO FACE WITH LOWLAND GORILLAS!


 

APPEARED IN


 
 DEEP in the equatorial rain forest of the Central African Republic lies a natural treasure that few have ever seen. We endured a 12-hour drive over rough trails to reach the Dzanga-Ndoki National Park, a pristine wildlife reserve in the southwest corner of the country, between Cameroon and Republic of the Congo. Our goal was to meet Makumba, a western lowland gorilla, and Makumba’s family.

 Our guide told us to stay together and to be on the lookout for elephants, since we would be hiking on trails that they used daily to search for food. But elephants weren’t our only concern. “If a gorilla charges you,” our guide warned us, “stand still and look at the ground. He won’t hurt you; he’ll just make a lot of noise. Don’t make eye contact with him. In fact, I find it helps just to close my eyes.”                      

Along with our guide, we were led by a tracker from the BaAka people, considered a Pygmy group because of their physical traits and short stature. By means of the faintest sights, smells, and sounds, the skilled native tracker can detect the presence of the most elusive animals. Swarms of maddening sweat bees surrounded us. We struggled to keep up as he strode with ease through the dense vegetation.

Soon our tracker was taking us through virgin forest where few Westerners have ever trod. Then, abruptly, he stopped and waved his arms over a large area near our path. There we could see crushed bushes and matted grass where young gorillas had been playing, as well as broken and stripped branches​—the remnants of a midmorning snack. Our anticipation mounted as we continued on.
 

A western lowland gorilla can grow to 6 feet (1.8 m) tall and weigh over 440 pounds (200 kg)

 
After about two miles (3 km), the tracker slowed his pace. To avoid startling the gorillas, he made a clack-clack noise with his tongue. Close by, we could hear deep grunts punctuated by snapping branches. Our guide slowly waved us forward. With a finger to her lips, she indicated absolute silence. She told us to crouch and pointed through the trees. About 26 feet (8 m) ahead, we saw him​—it was Makumba!                     

The once boisterous forest was now quiet, and all we could hear was the beating of our hearts. Of course, the question on our minds was, Would Makumba charge? Makumba turned his leathery face in our direction and, after what seemed to be a casual evaluation, welcomed us with a yawn. Needless to say, we were relieved!

Although in the Aka language the name Makumba means “Speedy,” during our time together, Makumba simply enjoyed a leisurely morning meal. Nearby, two juveniles wrestled and tickled each other. Sopo, a saucer-eyed ten-month-old, played near his mother, Mopambi, who gently pulled him back whenever his boundless curiosity led him out of arm’s reach. The rest of the family either stripped leaves and pith from branches or frolicked in groups, briefly glancing at us before losing interest and resuming their play.

After an hour, our time was up. Makumba seemed to feel the same, and with a single grunt, he hoisted himself up with his massive arms and moved off into the forest. Within seconds, the entire family vanished. Though we could spend only a short time with these magnificent creatures, the experience will stay with us for many years to come.

GORILLA LIFE

Gorillas build their ponderous bodies one shoot, branch, and leaf at a time, our guide explained. They also eat insects and seasonal fruits and can travel up to 2.4 miles (4 km) a day in search of food. The family may sleep on the ground or build nests in trees. The dominant male is called a silverback, since the fur on his back grays with age. The silverback usually sleeps on the ground to protect his family.

To help the gorillas become accustomed to humans, trackers visit them every day for at least five years. Habituated gorillas, as they are called, may then be visited by tourists, whose park entry fees help pay for research and for the conservation of this endangered species.
