Adding Nitrogen to the Soil

Adding Nitrogen to the Soil
We all know that lightning can be dangerous. Each year people are killed, and a great deal of property damage occurs because of lightning. We don’t usually consider the benefits of this powerful force. Nitrogen in the soil is essential for plants to grow and lightning is a natural method of adding nitrogen to the soil.

Although lightning can be dangerous, it also produces materials that are critical to life. All living things depend on the chemical element nitrogen. Your body contains molecules known as proteins. Proteins are made up of several elements, including nitrogen. Nitrogen is essential for proteins, but it is very hard to make nitrogen into proteins. Even though nitrogen makes up 78 percent of our atmosphere, we don’t get any nitrogen from the air we breathe. With each breath, we inhale and exhale nitrogen without using it. The nitrogen in the atmosphere has three electron bonds between the atoms, and that is a very strong and stable chemical arrangement. It takes an enormous amount of energy to break those bonds to free the nitrogen.

When lightning slices through the atmosphere, it knocks electrons from nitrogen atoms. The atoms are then free to combine with oxygen and hydrogen in the atmosphere forming nitrates. Rain carries this new compound to the ground enriching the soil with nitrates which are the building blocks of proteins. Plants synthesize the nitrates into proteins. When animals eat the plants, they get proteins. When we eat the plants or animals, we get the proteins we need to build more proteins.

Without lightning and the other processes for adding nitrogen to the soil, life could not exist on Earth. There is a purpose in the design of lightning. The Designer has also given us the intelligence to avoid many of the adverse effects of this powerful force.

Electrons Are Essential for Life

Electrons Are Essential in the Elements of Life
Everyone knows that electrons allow us to have computers and other electrical devices, but you may not realize how many ways electrons are essential. The mass, charge, magnetic properties, and spin of electrons are all designed to make life possible. It is amazing that something far too small for us to see is so important.

The changing momentum of electrons creates light which is essential for life. Electrons are also the fundamental cause of all that happens in chemistry. Atoms bond with other atoms to make molecules by exchanging or by sharing electrons. The complex organic molecules in your body, including DNA, are held together by electrons. The properties of every element in the universe are determined by how its electrons are arranged around the nucleus.

The oxygen atom with eight electrons joins with two single-electron hydrogen atoms to form water. The arrangement of the electrons in the oxygen atom causes the oxygen/hydrogen union to form in a way that gives water its unusual properties. The arrangement of electrons and the way the atoms bond causes water to dissolve salts, freeze from the top down, form crystals when freezing, and have surface tension. Without these unique properties of water, life would not be possible on Earth.

The arrangement of the six electrons in the carbon atom allows it to form enormous numbers of carbon compounds in various patterns. Because carbon can build so many organic compounds, our carbon-based life can exist. Without the particular arrangement of electrons in oxygen and carbon, life would not be possible.

Add to carbon and oxygen more than 90 other elements and their electron arrangements, and you can see that the probability of all of this happening by chance is not reasonable. We can be sure that a Master Designer created this complex system in which electrons are essential.

Beauty in Structural Color

Beauty in Structural Color on a Peacock
Some of the most beautiful colors you will see are found in birds and butterflies. We usually think of color as coming from pigments or dyes which reflect specific colors of light. However, the most intense and beautiful colors in the feathers of birds and the wings of butterflies don’t come from pigments. These animals display beauty in structural color.

Microscopic structures create structural color within the bird’s feathers or the butterfly’s wings which interfere with the frequencies of visible light. For example, the pigment in a peacock’s feathers is brown, but when you look at a peacock, you see blue, green, and turquoise in unusual patterns. Structural color can create color effects more intense than pigments, and structural color doesn’t fade like pigments. Structural color can even create an effect called iridescence in which colors change depending on the viewing angle. You can see this effect when you look at a CD or DVD.

What is the purpose of the colors in birds? The purpose may be for camouflage, to attract mates, or to indicate dominance. But in many cases, the colors seem to give no advantage. The beautiful colors merely exist for the beauty. When there is no evolutionary advantage for the colors, how did they get there? We humans appreciate beauty and enjoy looking at the beautiful colors. Could it be that colorful birds and butterflies were created by a Designer who is an artist who loves beauty, and who created us in His image. Could it be possible that God created the beauty in structural color for us to enjoy?

Ultraviolet Defense Mechanism

Ultraviolet Defense Mechanism
The human eye is an incredible creation. It not only allows us to sense the visual world around us, but its connection with the brain is amazing. The image that falls on the back of your eye is inverted, and your brain turns it over so that you see everything right side up. Most animals have eyes that do unique things, but not all of them use visible light. Ultraviolet light has a higher frequency than the light we can see. That means it is more energetic than the human eye can detect but less energetic than Xrays. Many animals use ultraviolet light as tools to enable them to survive. Some birds can see in the ultraviolet as do monitor lizards, some foxes, and some snakes. Sometimes ultraviolet vision helps them to find food. Other times prey use it as an ultraviolet defense mechanism.

Among the things those ultraviolet-seeing predators eat are lizards. A lizard called the blue-tongued skink lives on the ground throughout much of the continent of Australia. This lizard would seem to be an easy target for predatory birds and ground-dwelling animals. However, it has an ultraviolet defense. The tongue of the blue-tongued skink is highly efficient at reflecting ultraviolet light. When threatened by a predator, the lizard will open its mouth wide and stick out its tongue. The tongue will give off a blast of reflected ultraviolet light. Experiments show that birds and ground animals that see in the ultraviolet are startled by the sudden burst of ultraviolet radiation and veer away from the lizard.

One of the problematic things in designing any natural environment is building a system where living things can survive over the long term. If there is not a balance between predator and prey, the result is disastrous. Many years ago someone introduced rabbits to Australia. They had no natural enemies, and they reproduced so rapidly that soon the whole continent was overrun with them.

God has designed prey and predators in such a way that, if humans don’t mess it up, the environment and all of the living things in it can survive indefinitely. We are only now beginning to understand how difficult that is, even involving ultraviolet defense mechanisms. We need to allow the Earth to continue to be fruitful.

Coevolution – Stretching Truth to the Limit

Coevolution and Angraecum sesquipedale
One of the interesting characteristics of modern-day evolutionists is how far they will stretch credibility to support the model they assume to be true. Carl Zimmer in his book Evolution–The Triumph of an Idea gives a classic example of such a stretch when he calls our attention to an orchid found in Madagascar named Angraecum sesquipedale. It’s a story of coevolution.

You may recall from high school biology that flowers have both female organs called pistils and male organs called anthers. To cross-pollinate from one flower to another, the pollen from one plant must go to the “eggs” of another plant of the same species. The problem, in this case, is that the orchid has an 11 to 16 inch (28-40 cm) shaft at the bottom of which is a pool of nectar. It is far out of the reach of the usual pollinators of Madagascar. So how does pollination occur? It turns out that there is a microscopic moth that does the pollinating. What is unusual about this moth is that it has a tongue that is coiled up like a watch-spring taking up virtually no space. When the moth uncurls the tongue, it is 16 inches (40 cm) long. While the tongue is drinking in the nectar, the head and body of the moth are pollinating the orchid.

This is classic symbiosis. The orchid cannot reproduce without the moth, and the moth would starve to death without the orchid. The question is, “How could such a relationship came into existence?” Evolutionists would have us believe that the orchid evolved the shaft, the nectar pool, and the placement of the pollen at precisely the same time that the moth evolved the watch-spring tongue. At some point in the process, the two came together, and the symbiotic relationship was born.

The orchid and the moth are just one of a vast number of symbiotic relationships between species. Some of those mutual relationships are between predators and prey with physical characteristics that allow both to survive. Biologists say that it is just a matter of coevolution. However, as our understanding of genetics has improved, the difficulty in explaining these symbiotic relationships has gotten worse. Not only are the physical characteristics needed, but the genetic combinations must be very specific.

You will find more details on this interesting subject in F. LaGard Smith’s book Darwin’s Secret Sex Problem published by Westbow Press.

Jerboa by Design

Jerboa by Design
One of the things that scientists have studied in some detail is food chains. We now understand that for life to proliferate in harsh environments, it sometimes takes a highly specialized animal that is unique to that environment to fill the niche of food that other animals need. The deserts of northwest China, southern Mongolia, northern Africa, and the Arabian peninsula are good examples of harsh environments. The creature at the foundation of the food chain for higher forms of life is the jerboa by design.

This animal is about three inches (7.6 cm) long but has a tail that is over six inches (15 cm) and is flared at its end. The body is mouse-like, but the ears are a third longer than its head. The snout is like a pig’s, and its back legs look like a miniature model of a kangaroo. The back feet are elongated and very powerful and are covered with tufts of stiff hair. The front legs are very short, just barely able to reach its mouth.

The jerboa uses all of its unusual characteristics in a way that allows it to survive in an environment where most animals couldn’t last a day. The tufts on the feet enable it to walk on sand. The large ears are sensitive to very low volume sounds to hear predators approaching. The tail is a prop for standing still, and it gives stability when the animal jumps. It’s like a rudder in the air. When chased by a predator, the jerboa will change directions quickly and often to avoid capture. It can hop at up to 15 miles (24 km) per hour.

The jerboa ‘s diet is almost entirely insects, and it plays a major role in controlling the insect populations. The jerboa is a primary food source for birds of prey. The jerboa’s unique features enable it to survive even though it has many predators.

There are elaborate evolutionary explanations as to how this animal developed, but we see the jerboa by design. So many characteristics are unique to the jerboa that it requires a good imagination to derive a possible evolutionary scenario. God has designed creatures to fill even the harshest environments. Their capacity to adapt to those environments is further testimony to the wisdom built into the creation everywhere we look.

Dinosaur Mania in Media

Dinosaur Mania
We seem to have an obsession with dinosaurs, and popular science magazines can’t seem to get enough dinosaur articles. Dinosaur mania struck in May 2018 with Smithsonian Magazine, Scientific American, and National Geographic all featuring dinosaurs as their main articles.

Smithsonian told about new discoveries in China. Scientific American gave a speculative review of how new discoveries affect the classification of dinosaurs. National Geographic provided us with pictures of new fossils of the birds and bird-like dinosaurs. Their article makes the argument that modern birds evolved from dinosaurs after the asteroid collision that ended the dinosaur age. All of these articles are presented with wonderful pictures and charts.

Many people in both the scientific community and in the religious community seem to believe that there is a conflict between what these articles present and what the Bible says. Children receive indoctrination in dinosaurs from “Dinosaur Train” and other shows on children’s TV and websites plus revisions and repeats of “Jurassic Park.” It is important in all of this dinosaur mania that children should not be taught that the Bible is anti-science.

There is much about the history of the Earth that the Bible doesn’t address. There is an economy of language in the Bible, and it doesn’t give us information about how God prepared the resources He knew we would need. The Bible simply says He did it, not how He did it. Passages like Proverbs 8:22 ff and Romans 1:18 ff tell us that wisdom and design were involved, but they give no specifics about when it happened, how long it took, or what the processes were.

No Hebrew word used in the Bible could be applied to dinosaurs. The words used in the creation week referred to animals that Moses knew. We don’t see references to bacteria, viruses, platypuses, penguins, or organisms that use chemosynthesis instead of photosynthesis to produce their food. The Bible does consistently use four classifications of animals. First Corinthians 15:39 is the clearest statement of this: “All flesh is not the same flesh: but there is one kind of flesh of men, another flesh of beasts, another of fishes and another of birds.” In Genesis 1:21-27 the same classifications are used: cattle (behemah), winged fowl (kanaph oph), and great sea creatures (tannin). (For a detailed treatment of these Hebrew words, please see “God’s Revelation in His Rocks and His Word” on our doesgodexist.org website.)

We may be accused of being too literal in our understanding of these words, but we are looking for the agreements between the evidence and what the bible writers express. So were the dinosaurs birds or were they reptiles (part of the “flesh of fish” grouping)? Science has not answered that question yet. The National Geographic article pushes the argument hard that the birds are simply dinosaurs that survived the asteroid collision, but there are many scientists who disagree. Dinosaur mania has taught us much, but there is still much to learn.

Either way, the biblical account is not in error. It simply does not address what seems to have been an effective tool God used to help prepare the Earth for humans. “In the beginning God created the heaven and the earth” is short, brief, and leaves many questions for us to answer ourselves. The methods God used are not important to the overall message of the Bible. If God created everything, and if science is knowledge of what actually happened, they must agree. If they don’t agree, we either have a poor understanding of the scientific evidence or a poor understanding of what the Bible intends to convey. None of us are immune to those two problems, and that certainly includes your author. Let us keep learning and searching for positive answers and stop trying to generate conflict that is destructive to everyone.

Job’s Dinosaur

Job's Dinosaur
There is an interesting Bible reference to a fearsome creature in Job 40:15-24. Some creationists consider this to be Job’s dinosaur showing that dinosaurs and humans interacted at the time of Job. This is part of an attempt to suggest that dinosaurs and early humans were contemporaries to disprove the scientific evidence that dinosaurs became extinct long before humans existed on Earth.

The question is, “What kind of creature Job is describing?” Did an animal that existed in the past fit this description? The Hebrew word used for this creature is “behemoth” which literally means a large creature. Many animals that lived in the past and some living today could be called large creatures. We must look at the properties of this animal as described in the passage. We know that it was an herbivore (“feeds on grass like an ox”). Also, we know that “his tail sways like a cedar.” The description also tells us that he was virtually impossible to control.

The AP reported on May 5 about a discovery at White Sands National Monument in New Mexico. Scientists found human footprints inside the footprints of a giant ground sloth. The giant ground sloth was an herbivore that could stand seven or eight feet tall, had tight muscles and front legs tipped with wolverine-like claws. It had a huge tail used mostly for balance when it stood on its hind legs to get at vegetation. It appears that some humans were hunting the sloth and tracking it closely.

There is no denying that ancient humans interacted with these huge creatures. In the Natural History Museum in Chicago, there are displays of the fossils of these creatures, and the picture shows a recreated giant ground sloth at Kartchner Caverns near Benson, Arizona. The finding of human tracks intersecting the tracks of the sloths leaves no doubt about the fact that they were contemporaries. You can’t prove that Job’s dinosaur was actually a ground sloth, but the description fits very well. It is certainly more likely than the claim that the animal was a T-rex or a brontosaurus.

Insect Migrations and Earth’s Ecosystems

Insect Migrations and Earth's Ecosystems
It is spring in the Northern Hemisphere, and one of the joys of spring is seeing the amazing migrations of birds as they move north from their wintering grounds. We watch the birds without thinking of the logistics that are involved in millions of birds moving over fast distances. How do you feed these hordes of living things? Their needs are even greater than usual because of the energy required for the long flights. We may not realize the importance of insect migrations that occur at the same time. What collateral benefits does this system create?

Dara Satterfield of the Smithsonian Institution in Washington, D.C. says, “Trillions of insects around the world migrate every year, and we’re just beginning to understand their connections to ecosystems and human life.” This migration not only feeds birds, but they pollinate wild plants and gobble agricultural pests.

We have written in our quarterly journal about the spring migration of monarch butterflies from Mexico to North America. In Europe and Africa, the migration is even more amazing and complex. Each spring the painted lady butterfly travels from Africa across the Sahara desert and the Mediterranean Sea into Europe and then retraces that journey in the fall. Because their life expectancy is so short, it takes six generations of butterflies to accomplish this migration. The butterflies avoid the extreme heat of North Africa in the summer, but they arrive in Africa just in time to feed from the flowers in the fall. Those butterflies are vital to the balance of living things in Europe.

Some of the insect migrations are very important to human food production. The marmalade hoverfly eats aphids during the larvae stage, and as adults they pollinate plants. The volume of insects is seen most clearly in the Pyrenees and Alps. Millions of hoverflies use the winds blowing through the mountain passes to get from one place to another. Scientists have been monitoring this migration because of its economic importance to agriculture in Africa and Europe. There is also a hoverfly migration in the western United States, but it has not been studied.

The size of these insect migrations is hard to comprehend, and we fail to understand the complexity of this system. Studies in the southern United Kingdom estimate that 3.5 trillion insects migrate over that area every year. Without those insect migrations, ecosystems on this planet could not exist.

Those of us who believe in God’s design of the creation see this as one more evidence that the simple statement “In the beginning God created the Heaven and the Earth” is a massive oversimplification. We truly can “know there is a God through the things He has made” (Romans 1:20).

Mollusk Designs

Mollusk Designs
Many of the invertebrate creatures known as mollusks build interesting shells. An article titled “How Seashells Take Shape” describing a study of mollusk designs appeared in the April 2018 edition of Scientific American (page 70). The article begins with this paragraph:

“Mollusks are fabulous architects. They build houses that protect their soft bodies from predators and the elements–shells of uncommon strength, durability and beauty. Many of these shells have spectacularly complex shapes–logarithmic spirals bedecked with fractal spines or other ongoing elements, all executed with near-perfect mathematical regularity. Yet mollusks, of course, know nothing of math. How, researchers have wondered, do these humble creatures produce such intricate patterns so precisely?”

The article goes into the mathematics of the shells and how the animals use complex processes that scientists are still studying. It isn’t just the shapes that are an issue here, but also the physical properties of the shell material including elasticity, ductility, tensile strength, and the use of oscillatory systems. Scientists are trying to understand the fractal-like spine pattern in some mollusk designs. Also, the researchers are curious about why 90 percent of mollusk shells are right-handed and only 10 percent are left-handed. Other “exquisite ornamentations” create a mystery for scientists to study.

Romans 1:18-22 tells us that “we can know there is a God through the things He has made.” The complexity of something as basic as a seashell can speak to us about the design God has used in everything He does. It is only with the advent of mathematics and engineering that we can duplicate what we see in nature. Seashells are an intricate example of the design of living creatures.
