Why Is There Color in Our World?

Why Is there Color in the World?
One of the joys of life is the beauty that we see in the natural world. The beauty of flowers is so great that we decorate our homes inside and out with flowers of every description. People will get out of bed early in the morning to watch a sunrise display colors of incredible beauty and complexity. We admire the work of artists and photographers who can capture a permanent record of the colors of the world on canvas or film. Why is there color in the world?

There are hundreds of papers that have been written by scientists and science writers concerning the reason for color. The design of the Earth and of the life systems on Earth frequently demand that certain colors exist. For example, the green in vegetation is necessary to protect plants from the high energy wavelengths of the Sun’s light.

There are some colors in the natural world, however, that seem to defy a naturalistic evolutionary explanation. Flowers living in identical environments will frequently have radically different colors. If we postulate that the colors are different to attract different pollinators, we run into logical problems. Wouldn’t the most efficient pollinators provide the same advantages to all flowers of similar geometric design? In caves deep in the ocean, there are some of the more vividly colored tropical fish. These fish never see sunlight and have no camouflage advantage given by their colors. There are worms and burrowing animals in thermal vents deep in the floor of the ocean that display rich and beautiful colors.

A skeptic may reply that these colors are a chance consequence of the materials that make up the bodies of these organisms. The fact is that, in many cases, the colored materials in the organism are inconsequential to the survival of the organism. We would suggest an equally plausible and perhaps more realistic explanation. Could it be that a God of intelligence and creative power designed the creation not only with functional wisdom but also with aesthetic intelligence?

Why is there color? God obviously enjoys beauty. We were created in God’s image, and therefore we enjoy the beauty of the world around us. Beauty is one of the things that makes our sojourn on this planet worthwhile.

Nursing Orangutans and Evolution

Nursing Orangutans
As scientists study different animals in their natural environment, they frequently learn things that complicate accepted pictures of animal history. A recent series of studies of nursing orangutans in Borneo and Sumatra has shown that weaning doesn’t occur in these animals until they are more than eight years old. That is a record lactation period for any wild animal.

Determining the length of nursing for orangutans has been difficult for various reasons. For one thing, the nursing takes place high in the trees, so scientists have difficulty observing. Add to that the fact that these animals are hairy, so it becomes difficult to see what is going on. Some have suggested that the babies are just cuddling.

Researchers finally settled the question by studying orangutan teeth. Studies of the layers of material containing barium in the teeth of the babies indicate that they really are feeding. Museums have collections of orangutan teeth from years ago when these animals were not considered to be endangered and were often killed by collectors. Calcium and barium from the mother’s body go into building the nursing infant’s teeth. Primate teeth are built up with a microscopic layer each day. By examining the layers, scientists can tell when the infant orangutan stopped nursing because there is a greater concentration of barium in the nursing layers. Examining teeth from orangutans at different ages, the scientists determined that nursing can continue through age eight.

Some evolutionary theories have difficulty with these very long lactating periods. Not only is the female not receptive to males during that eight years, but she must continue to produce milk. In milk production, the mother is literally dissolving some of her body to provide nourishment for the young. These two factors seem to be counter to evolutionary models for survival. These new discoveries concerning nursing orangutans may cause some rethinking concerning theories of primate evolution.

Origin of Life Problems Admitted

Wing Challenge to Origin of Life
One of the more honest and fair writers in modern scientific publications is Dr. Bob Berman. He has a regular column in Astronomy magazine and an interesting website. In the September 2017 issue of Astronomy (page 10), he has an outstanding brief review of the problems involved in trying to explain the origin of life. He begins by pointing out that the definition of “life” has been an issue because of questions such as whether or not a virus is alive. Viruses have no metabolism, they don’t feed or breathe, and yet they reproduce.

Berman then reviews some of the parameters necessary to consider when addressing the origin of life. Chirality is a major issue because amino acids that make up proteins come in right- and left-handed versions. Life on Earth is made up of only left-handed amino acids. Sugars used by the proteins are limited to the right-handed direction, and so is DNA. The wrong chirality just will not work to support life, so how could nature sort out the chirality? If life is easy to produce, why don’t we see it coming into existence all over the Earth? The “amoeba-to-man” model assumes that it only happened once, which conflicts with the view that life is abundant in the cosmos.

What is especially interesting is that Berman raises questions about the ability of evolution to explain on a chance basis some of the designs we see in living things. He uses the example of the airfoil that all flying forms of life have. The upper surface is convex using the Bernoulli effect to produce lift. The earliest bird and the flying reptiles all had a wing design that works. Trial and error would not work well to explain how the wing design would come into existence by chance. Berman points out that “some 400,000 cells would all have to simultaneously mutate in just the right way to create a properly shaped wing. This defies an evolutionary hypothesis.”

Berman concludes with the statement, “I’m not invoking spirituality, merely that the effect of random collisions and mutations is not always a workable answer. So perhaps nature is inherently smart.” I would suggest that wing design is just one of a massive number of design features that allow life to exist.

Berman quotes Francis Crick, the co-discoverer of DNA’s double helix as saying that the origin of life is “almost a miracle, so many are the conditions which would have had to have been satisfied to get it going.” We don’t invent a “god” to explain these things, but we would point to these things as one more evidence that there is a God and that blind chance is not a good designer of the complexity we see in the world around us.

Just Right Moon

Solar Eclipse Thanks to Just Right Moon
In a few days, a total solar eclipse will cross the full width of the United States, and you can give credit for that to the just right moon.

We have looked at the “how” and “why” of total solar eclipses. We have considered what value total solar eclipses have. We have seen that a total eclipse helped to confirm a very important scientific principle. Also, we pointed out that solar eclipses happen only at the time of the new moon when the Moon is between the Earth and the Sun.

A new moon occurs about every 29 days, so why doesn’t an eclipse happen at each new moon? That’s because the plane of the orbit of the Moon around the Earth is about five degrees off from the orbital path of the Earth around the Sun. Because of that difference, a solar eclipse happens only when the Moon crosses the path of Earth’s orbit around the Sun (called the ecliptic). A TOTAL solar eclipse happens only when the Sun and Moon are exactly aligned.

What would happen if the orbit of the Moon were on the same plane as the ecliptic? At every new moon we would have a total solar eclipse, and at every full moon, we would have a total lunar eclipse. So the Sun would go dark in the daytime somewhere on Earth every month, and the full Moon would also go dark monthly. The influence of the Sun’s gravity on the lunar orbit might cause more serious problems.

No other planet has a moon that plays such an important part in creating an environment suitable for life. The Moon is right where it should be to serve life on Earth. Our just right Moon lights the night, creates the tides that clean our estuaries, stabilizes Earth’s rotation, and occasionally provides a total solar eclipse that gives us a glimpse of God’s marvelous design of our solar system.

Plastic-Eating Worms

Food for Plastic-Eating Worms
One of the confusing points about evolution for many Christians is not understanding that there is a difference between the fact of evolution and naturalistic theories of evolution. Evolutionary adaptations have given us plastic-eating worms.

Attempting to say that evolution eliminates God from the picture of creation is an incredibly ignorant statement, and yet we see it in both atheist and Christian papers. The word “evolution” means “unfolding change.” The fact that God engineered life in such a way that living things can change is one of the most incredible examples of design.

Darwin’s work in the Galapagos Islands showing that finches could change physically to meet the local food supply does not contradict the Bible in any way. When we visited Darwin Station in the Galapagos and talked with the workers, they were dumbfounded to hear that anyone thought there was a biblical problem with the work they were doing there.

The August 2017 issue of Scientific American (page 21), carried an article about the larvae of the greater wax moth that has mutated so that it can consume polyethylene plastic. Humans produce some 300 million metric tons of plastic every year, and this material is clogging landfills and showing up in lakes and streams. To find a way to biodegrade this material would be a huge ecological breakthrough, and it is possible because of the design of the genetics of the wax moth larvae. Beeswax is the main food of the larvae, but the mutation allows them to degrade polyethylene as well.

The scientists involved are studying the process to discover the enzyme that the plastic-eating worms use to break down the polyethylene. God apparently built a solution to the biggest waste problem we face today by the design of the genome of the wax worm.

Current Biology journal originally published news of this discovery on August 7, 2017.

Tyrannosaurus Rex, the Vulture

Tyrannosaurus Rex
We tend to view Tyrannosaurus rex as a 20-foot tall flesh eater who ran down its prey. Some have called this dinosaur “the most efficient carnivore who ever lived.” Science fiction movies like Jurassic Park have probably been the main source of this image, but the fact is that T. rex was nowhere near that fast.

Past studies of T. rex suggested that its huge mass–in the vicinity of nine tons–prevented it from running down much of anything. The muscle strength needed to accelerate that mass is simply not available to any form of life. Now simulations of acceleration and bone strength have verified that understanding. A speed of about 12 mph would have been the top limit for T. Rex and for only a short distance. That means a human could easily outrun a T. rex.

Tyrannosaurus rex was probably more of a scavenger than a hunter. There were other slow-moving dinosaurs such as Edmontosaurus, Triceratops, and Ankylosaurus that T. rex might have been able to catch. It is more likely that the T. rex population were the vultures of their day, not the lions of their day.

God created dinosaurs for a purpose, and every year we understand more about how they helped sustain the ecosystem that produced many of the resources we need. Every little boy seems to be fascinated with the media presentations of these creatures, but they really were not that glamorous.

Super Night-Vision in Frogs

Super Night-Vision in Frogs
Almut Kelber is a sensory biologist at Lund University in Sweden. For many years Dr. Kelber has been studying the super night-vision in frogs that allows them to hunt and move about in extremely low light levels.

In the August/September issue of National Wildlife (page 10) the group that Dr. Kelber leads reports that amphibians have unique rods or photoreceptor cells in their retinas that are not found in any other vertebrates. These receptors allow frogs not only to see in the dark but to see colors in extreme darkness. Humans can’t distinguish colors in low light, but frogs can see colors in light levels where human eyes would not see anything at all. Dr. Kelber did not expect to find that “these animals can see color in extreme darkness, down to the absolute threshold of the visual system.”

Over and over we see specific equipment built into living things that allows them to survive in their environment, defend themselves against predators, and find unique access to food. You can believe that this is a simple trial and error situation, where having the equipment promotes survival and not having the equipment is lethal. Or you can believe that an intelligence designed and engineered these structures to allow our planet to be a unique oasis of life.

Since we find this super night-vision in frogs everywhere in the world, it is difficult to believe this is a product of isolated chance. “We can know there is a God through the things He has made” Romans 1:18-22.

Scientists and God: A Different View

Scientists and God
J. B. S. Haldane in 1914

In each issue of our printed publication, we have a feature called Scientists and God, in which we quote from a leading scientist who is also a believer in God. Today I would like to do something a little different. I want to quote the words of a leading scientist who was not a believer.

J. B. S. Haldane (1892–1964) was a British geneticist and evolutionary biologist. He was also an outspoken atheist and a Marxist. Because of the political controversy caused by his Marxist ideology, he left England in 1956 and spent the remainder of his life in India.

Haldane was a brilliant man who made contributions in the areas of genetics, evolutionary biology, and mathematics. In many ways, he was ahead of his time. He proposed the central ideas of in vitro fertilization. He was the first to suggest human cloning. In fact, he coined the use of the term “clone” for that purpose. He also helped to create the science of population genetics.

Haldane proposed correctly that sickle-cell disease gives immunity to malaria. He prepared gene maps for color-blindness and hemophilia. Nobel Prize winning biologist Peter Medawar called Haldane “the cleverest man I ever knew.”

In 1929, Haldane introduced the “Primordial Soup Theory,” which said that life began on the early Earth in a chemical soup where the elements of life came together. That theory became the leading concept of abiogenesis–the idea of life coming from non-living matter by a natural process. Haldane’s theory led to the famous Miller-Urey experiment in 1952. In that experiment, Stanley Miller created a sealed container with the chemicals thought to have been part of the early atmosphere of Earth. He subjected the chemicals to an electric spark and collected some amino acids which are the building blocks of proteins. The news media went wild over “creating life in the laboratory,” but that was an example of media exaggeration–or as it would be called today “fake news.”

Incidentally, science has since shown that the Miller-Urey experiment did not emulate the conditions or chemicals of the early Earth and therefore is not a valid demonstration of the first step in abiogenesis. However, it is still shown to students in school textbooks because science has not produced anything better, and it is easy to understand. Today’s attempts at abiogenesis are far more complex, proving that it takes great intelligence and carefully controlled lab conditions to produce even the basic building blocks of life. In other words, it takes intelligence to create life, which has been our message for many years.

Haldane wrote numerous books presenting his ideas and defending Darwinism. In 1949 he debated British ornithologist Douglas Dewar on the topic “Is Evolution a Myth?” In that debate, Haldane said that evolution would not be capable of producing “various mechanisms, such as the wheel and magnet, which would be useless till fairly perfect.” In other words, if those mechanisms could be found in living organisms it would be an indication that evolution did not create those organisms.

Since that debate, we have found magnets in anaerobic bacteria which are considered to be the most “primitive” forms of life. The sightless, single-celled magnetotactic bacteria consume iron and produce magnets which they use to guide them to anaerobic areas that are safe for them to live. The magnets they produce are better for some scientific purposes than what humans can produce in the laboratory. Turtles, birds, and other more advanced animals also use magnets for navigation. Wheels can also be found in living organisms. As Janine M. Benyus (another Darwinist) wrote in her book titled Biomimicry, “Even the wheel, which we always took to be a uniquely human creation, has been found in the tiny rotary motor that propels the flagellum of the world’s most ancient bacteria.”

So wheels and magnets are found in the most “primitive” and “ancient” of single-celled bacteria. If that 1949 debate were taking place today, I doubt if J. B. S. Haldane would say that those mechanisms could disprove evolution. On the subject of Scientists and God, there are many views. Our view is that those mechanisms found in bacteria indicate an intelligent Creator who understood magnets and wheels long before humans did.

Majesty in Miniature

Majesty In Miniature

“Majesty in Miniature” is the title of an interesting article in the July 2017 issue of National Geographic (pages 99-118). The article is about the amazing hummingbirds.

Scientists have had a hard time getting data as they try to understand how hummingbirds do what they do. The birds fly at speeds up to 35 mph (56 kph) and they have a “reverse gear.” Their metabolic rate is the highest of any vertebrate on the planet. For every minute they are in flight, they drink more than 12 ounces (355 ml) of water. They consume more than their body weight of nectar every day. Their tongues lap up to 15 times a second. Proportionally their brain is one of the largest in the animal kingdom making up 4.2% of their body weight. It is only with the advent of high-speed cameras and advanced wind tunnels that some of the mysteries of the majesty in miniature have been answered.

Hummingbird brains have a large hippocampus which allows them to remember locations. Their brain has a large lentiformis mesencephali motion sensor which gives the bird stabilization when flying. It has a small arm wing which allows wrist motion to control a larger area of the wing leading to a more powerful upstroke. When a hummingbird hovers, it rotates its wings between the upstrokes and the downstrokes making a figure eight motion. This motion creates vortexes that allow both the downstroke and the upstroke to provide lift. Birds such as pigeons push down to propel forward, but there is no lift in the upstroke. The design of the hummingbird wing gives it the unique ability to get lift out of both strokes.

The design of all of these features defies any chance explanation. Nearly everything the hummingbird does is unique to that species. We don’t see birds with some of these characteristics, and yet all of them are essential to the hummingbird’s survival. Indeed this bird is majesty in miniature, and a testimony to God’s wisdom and design. He has equipped all creatures to live in their particular, unique environment.

Summer Snow in Michigan

Summer Snow
Eastern Cottonwood Seeds

Recently my driveway was covered with Michigan summer snow. The temperature was 92 degrees, and the snow was falling at an alarming rate. I didn’t get out my snow blower, but I did get out my leaf blower.

Michigan summer snowflakes are one-to-two inches in diameter. Contained within each snowflake is a seed. These snowflakes can travel for miles when the wind is blowing because they are carefully engineered so that their density is the same as the air here in Michigan on a hot early summer day. They only stop when they hit an obstruction, but even a dandelion or a tall weed can stop them. The cotton that surrounds the seed is highly soluble in water. As soon as it rains or the sprinkler system comes on, the cotton will dissolve, and the seed will fall to the ground and try to become a new cottonwood tree.

The eastern cottonwood is the state tree in Kansas, Nebraska, and Wyoming. It can grow as much as six feet in one year and can become one of the largest trees in North America. Because they grow so fast, the wood of cottonwood trees is not very strong. But when you have a tree 190 feet tall, there is a great deal you can do with it. The Native Americans made canoes from the trunks of cottonwood trees. They used the bark of the tree as forage for horses, and the sprouts for food and medicinal tea.

Cottonwood trees come in both male and female varieties with different life cycles. The males don’t make seeds. In the spring the female trees have tiny red blossoms. When the females are pollinated by the male trees, they form a spherical cotton ball with a seed inside. The volume of the cotton is exactly enough to give buoyancy to lift the seed off the ground, but not so enough for it to be lost in the atmosphere. The cotton balls with their seeds flow across the landscape in the same way that cold air blows snow in winter. The seeds can be so thick that we can’t see across our street.

It is a wonderful thing to see all the different methods that God designed into trees to allow them to reproduce. Maple trees use tiny helicopters to lower seeds to the ground. Oak trees use acorns to entice squirrels to bury their seeds. Squirrels have enough memory space in their brains to remember where most of the seeds are, but not all of them. Cottonwoods create summer snow.

Romans 1:20 tells us that we can know there is a God through the things He has made. Our Michigan summer snowstorm is just one more example of that truth.
