Trout Fins Are Designed for Efficient Swimming

Technology has allowed us to see the design of things in the natural world. Dr. Haibo Dong at the University of Virginia has used 3D computer models to study the turbulence created with each fin of a trout. American Scientist magazine states, “Interactions between swirling eddies created by a swimming trout show how its body is optimally laid out for energy-efficient movement.” Trout fins are designed for efficient swimming.

A trout’s body is shaped to swim through the water with less drag than any other shape. However, the role of various fins is not easy to see. Virtually all fish have a dorsal fin on the back and a caudal fin on the tail. Trout have other fins, including pectoral fins near their heads and pelvic fins near the center of their bellies. Toward the back of the trout’s body is a small adipose fin on top and an anal fin on the underside. The researchers have shown that the fin locations increase the thrust the tail produces. The anal fin produces 8.6% more thrust reducing the drag by 18.6%. Trout fins are designed for efficient swimming, or as the researchers conclude, “the whole trout is optimized for efficient swimming.”

Other fish have different fin arrangements to match their survival needs. A tuna living in the open ocean has a different layout of fins because it is designed for speed rather than efficiency. Fish that confine their existence to the bottom of a lake or river will not have the same fin layout as the tuna or the trout. For example, catfish have a fin arrangement designed for protection. Those of us who have grabbed a catfish incorrectly may have suffered a painful jab from its fins. Trout fins are designed for efficient swimming since they make long migrations, swimming upstream and sometimes over waterfalls.

Our technology allows us to understand the various designs seen in living things. Trout fishermen know that catching a trout differs from catching any other fish because of their mobility and muscular nature. Research has shown that the trout’s design shows wisdom right down to the shape and location of its fins. We suggest that this design is the product of a Designer, not just blind opportunistic chance. Genesis 1:21 tells us, “God created the great creatures of the sea and every living and moving thing with which the water teems..” Thanks to technology, we understand how over-simplified that statement is.

Just Right for Life to Exist

Since astronomers have discovered more than 5,000 exoplanets orbiting stars other than our Sun, many insist there must be life elsewhere in the cosmos. For those of us who believe in God, that isn’t really an issue. If there is life out there, God created it, but the Bible only speaks to our planet. However, the evidence is growing that our planet is more unique than most people realize. A “Goldilocks” planet is at the proper distance from its star so that the temperature is “just right” for liquid water to exist on the surface. Some exoplanets appear to be in the habitable zones of their stars, but many other factors must also be just right for life to exist there.

Most known exoplanets are like Jupiter, having no terrestrial surface. To support life, a planet must be the right size, have a stable orbit inside the habitable zone of a stable star, and have the right atmosphere. It must also have working plate tectonics and a large moon to maintain a stable axis tilt. To be just right for life to exist, a planet must also be in the habitable zone of its galaxy – not near the center, exposing it to lethal gamma-ray bursts.

Our Sun is a G spectral star, but only 9% of the stars in our galaxy are that type. M-class dwarf stars are the most common and long-lived stars, but they emit large amounts of radiation that would cook any life on their planets. Also, planets around such a star would become tidal-locked, with one side facing the star being excessively hot while the other remains cold.

Another star system requirement for life would be having outer planets large enough and in the correct position to sweep away asteroids and comets that would bombard an inner planet. To support life, a planet also needs a strong magnetic field to shield the surface from the star’s radiation and cosmic rays.

Our Earth is just right for life to exist. We are defining life as the biology books do: being able to move, breathe, respond to outside stimuli, and reproduce. Any conjecture about fire people or rock people is in science fiction – not scientific fact. The bottom line is that Earth is a special place created by God for a special purpose and is unique among all other objects in the cosmos.

Firefly Frequencies at Work

There are 56 species of flying lightning bugs, or fireflies, and each emits light of a different frequency. The different firefly frequencies cause different colors, such as green, yellow, or red, but science has found that the frequencies are far more precise than the color. The fact that each species has a particular wavelength allows fireflies to find mates, even in an area where other life forms use bioluminescence.

Fireflies have four stages. They begin as eggs but spend most of their 61-day existence as larvae, eating snails, slugs, and worms. They have a pupa stage just before becoming adults. Bioluminescence serves mainly as a way for males and females to find each other, and having the right frequency is essential in that process. Research is continuing on how the frequencies are specified, but 56 species means that the frequency variation has to be carefully created and controlled.

Most living things have methods of communication that serve multiple purposes. Communication allowing males and females to find each other is always risky because it exposes them to predators. Because fireflies’ flashing is sporadic and not a steady glow, they are less likely to be eaten. If you have tried to catch these flying lightning bugs, you know how hard it is because they flash and run, making them hard to locate.

We can learn many things by studying the natrual world, including the chemistry that allows various firefly frequencies of bioluminescence. In the firefly we see another demonstration of God’s wisdom and intelligence.

Animal Memory Capacity

One of the most interesting areas of study in living things is animal memory capacity. Memory is designed into animals to benefit both them and other forms of life in their ecosystem. We see a good example of partial memory in squirrels who bury massive numbers of seeds, such as acorns, but only remember where they put a fraction of them. What that means is that the squirrels have enough to eat, but they plant trees over a huge geographic area. There are many forms of life where partial memory serves a similar purpose.

On the other hand, some life forms remember virtually 100%. A good example of this is Clark’s Nutcrackers. They survive on pinion seeds, and a single bird may hide as many as 30,000 seeds, placing 4 or 5 seeds in each spot. Throughout the winter, the Nutcracker, when hungry, will return to each hiding place to get food. By the time spring arrives, this bird will have consumed almost all of the seeds hidden in thousands of different places.

It is interesting that different forms of life have different memory capacities that benefit not only themselves but also their environment. You could compare it to thumb drives for your computer, having different memory capacities depending on the thumb drive’s design. God has placed different storage in the memory of the brain of each creature He created. In humans, that storage capacity is huge and can be accessed in many ways. In the animal world, there is an interaction with the environment that is beneficial to the animals and the environment.

Trying to explain this animal memory capacity by evolutionary reasoning is incredibly difficult and is full of assumptions. Those of us who believe in God as the creator understand why this kind of thing occurs over and over. It speaks of God and His wisdom and design in the world around us.

One of the Natural World’s Most Amazing Things

The hummingbird is one of the natural world’s most amazing things. Researchers have compiled new hummingbird data using modern methods, including high-speed photography. An adult hummingbird weighs roughly 4 grams, and to get a handle on that, a penny weighs about 2.5 grams. There are 21 species of hummingbirds in North America, and one species, called the bee hummingbird, weighs less than a penny.

Hummingbirds don’t beat their wings as most birds do; instead, they rotate them in a figure-eight pattern. That allows them to hover and fly backward or even upside down. The rate of wing motion is up to 80 cycles per second. That is within the range of human hearing and explains the humming sound that gives these birds their name. The metabolic rates of hummingbirds are amazing, as their heart rate is around 1,260 beats, and their breathing rate is 250 breaths per minute. These rapid rates mean hummingbirds may find a place to rest as often as every 15 minutes.

One of the natural world’s most amazing things is that hummingbirds can travel non-stop across the Gulf of Mexico in spring and autumn. Before embarking on that trip, they double their body weight with nectar and insects. When the temperature is low, they go into hypothermic torpor to survive.

The hummingbird’s eyes have a dense concentration of cones in their retinas containing pigments that act as filters to heighten color sensitivity to red while muting blue. Pollination is a major purpose of hummingbirds. Ruby-throated hummingbirds deposit ten times as much pollen as bumblebees, and their life expectancy is 3 to 6 years.

It is with great joy that I watch hummingbirds come to the feeder outside my office window. Their various characteristics speak of the wonder of God’s creation, defying chance explanation. Once again, we “can know there is a God through the things He has made” (Romans 1:20). The hummingbird is one of the natural world’s most amazing things.

Brown Bats and Tiger Beetles

One of the challenges in the natural world is keeping a balance between predators and victims. If predators have a foolproof method of locating their prey, they will eventually wipe out their food population, and the predators will die. That means victims must have some method of avoiding predation. Harlan Gough, a conservation entomologist at the U.S. Fish and Wildlife Service, has done some amazing experiments with brown bats and tiger beetles.

When Gough placed brown bats and tiger beetles into a cage together, the bats ate all of the tiger beetles. In the wild, this doesn’t happen because tiger beetles have a way of mimicking an insect known as a tiger moth. Tiger moths live in the same areas as tiger beetles, but bats don’t eat them because they have a foul taste. Dr. Gough found that tiger beetles can emit the same clicks as tiger moths when they sense predatory bats. They pull their forewings into the path of their beating hind wings, creating a high-pitched click similar to the tiger moth’s sound.

In the natural world, all living things have one or more methods to avoid predators. It may be smell or sight, but this may be the first case of using sound to deter predation. Realize that all of this happens at night when ultrasonics are more useful than sight and smell. No prey survival methods are 100% sure, so predators can still survive, especially when the food source is injured or sick.

We suggest that this case of brown bats and tiger beetles is another instance where there are too many variables to assign to chance. Having tiger moths with bad taste living in the same Arizona desert with tiger beetles seems more likely to be a planned and designed system than a series of accidents. The statement in Romans 1:20 that “we can know there is a God through the things He has made” seems to be supported again as we learn more about the functioning of the natural world.

Qiviut Fiber and the Muskox

One of Earth’s warmest, finest, and rarest fibers is not produced by humans. Qiviut is the Inuit language name for the coat of the muskox, which is native to Alaska. Muskox qiviut fiber is lightweight but stronger and warmer than sheep wool. The muskox wears its two-inch-thick coat throughout the winter and sheds it in the spring. Researchers are making a major effort to create a synthetic fiber that is even close to what the muskox produces.

Muskox inhabit the tundra of northern Alaska, where winter temperatures drop far below zero, and the wind is constant and substantial. Most animals migrate to warmer areas or hunker down into dormancy to wait out the cold tundra weather. The muskox will paw through the snow to reach moss lichen, willows, and roots while ignoring the typical blizzard conditions.

Alaskan farmers raise herds of muskox and ship qiviut to a mill that spins it into yarn. Qiviut is a challenge to spin because it has a tiny diameter, short staple length, and is smooth and slippery. Sheep wool is coarse with deep interlocking scales, making sheep wool yarn strong, but it also causes shrinkage, felting, and scratchiness. Qiviut is sometimes blended with silk.

Interestingly, human work with fibers of all kinds for thousands of years has not come close to the qiviut fiber of the muskox. God’s design of materials for every type of climate and condition speaks loudly of His wisdom and design. The muskox is an excellent example of fiber design not seen in any other life form on our planet.

Media Hype About Exoplanets

The media continue to make scientifically inaccurate claims to an unsuspecting public. Media hype about exoplanets suggests that life on Earth is not unique, and many habitable planets exist throughout the cosmos. A USA Today article on May 31, 2024, refers to exoplanet Gliese 12 b as a “super-Earth.” It quotes Dr. Masayuki Kuzuhara, assistant professor at the Astrobiology Center in Tokyo, saying, “Although we don’t know whether it possesses an atmosphere, we’ve been thinking of it as an exo-Venus with similar size and energy received from its star as our planetary neighbor in the solar system.” So, what are the facts about Gliese 12 b?

Gliese 12 b is very close to the star Gliese – just 7% of the distance between the Earth and the Sun. That means the radiation from the parent star is sweeping across the planet, and because it orbits once every 12.8 days, any activity on the star will dramatically affect the planet. Gliese is a red dwarf star, not a star like our Sun. It is only 27% of the size of our Sun, with about 60% of the Sun’s surface temperature. Red dwarf stars do not emit wavelengths of light needed for life forms like us. Understand that life cannot exist when the only light reaching the planet is Xrays, UV, Infrared, and radio waves.

Considering all these factors, it is highly improbable that Gliese 12 b has an atmosphere, and the presence of water, oxygen, hydrogen, or ammonia has not been detected and is unlikely to be found. Despite the media hype about exoplanets, there is no scientific evidence to support the existence of life without these elements.

Critics will say, “Maybe the life forms out there are not like us and can survive under different kinds of radiation.” Life is defined as that which can move, breathe, respond to outside stimuli, and reproduce. If you want to speculate that life can be fire people or stone people, you can do so, but scientifically, such hypothetical forms do not qualify as “life.” There is no evidence anywhere that such forms exist.

When you know the facts of what life requires, you cannot logically believe that life forms different from ours can exist in the physical creation. Media hype about exoplanets suggests alternatives that have no scientific support. Science supports Genesis 1:1: “In the beginning, God created the heaven (space) and the Earth.”

Earth Is a Very Special Place

As of May 9, 2024, astronomers have discovered 5,616 planets orbiting other stars. Of that number, 1794 are “gas giants” like Jupiter, 1,920 are Neptune-like planets, and 1,695 are “Super-Earths,” solid planets like Earth, but much larger. That means they will have denser atmospheres of gases that are inhospitable to life. That leaves 207 terrestrial planets, of which seven have unknown features. As the James Webb telescope gathers data, these numbers will change, but the message is already clear. Earth is a very special place, and most of the exoplanets we see are unsuitable for life of any kind. By life, we mean the usual biological definition – that which can move, breathe, respond to outside stimuli, and reproduce.

Hollywood, TV, and books have given us some creative fantasies about space travel, but there are specific limitations on where humans can go. The closest star to Earth is 4.3 light years away, meaning that if you could travel at the speed of light, which is impossible, it would take 4.3 years to reach that star. The closest major galaxy to our Milky Way is Andromeda, 2,480,000 light years from Earth. That means the light coming to us from Andromeda left there 2,480,000 years ago. Humans traveling to Andromeda at the speed of light would need that long to get there. The return to Earth would take just as long, and the Earth would have aged 4,960,000 years while they were gone, even though time would have slowed for the travelers.

All of this is to say that traveling to another galaxy and back is pure fantasy and not an option for any of us. It also says that alien visits to the Earth are another fantasy that may make good movies but are not supported by evidence or common sense. Some people suggest that we are not alone and that aliens are affecting human activities, but that is a fantasy we cannot seriously consider.

The ancient psalmist wrote, “When I consider Your heavens, the work of Your fingers, the moon and the stars, which You have ordained, what is man that You are mindful of him, and the son of man that You visit him?” (Psalms 8:3-4). Another Psalm says, “The heavens declare the glory of God; the skies proclaim the work of His hands” (Psalms 19:1). The ancients wrote about what they could see, but now we can see so much more. We are blessed with a whole different picture of the size, power, and wisdom of God’s creation as we realize that Earth is a very special place.

The Grand Canyon and Change

The Bible tells us that God designed planet Earth with the capacity to change, and the geologic and fossil record agrees with that. The Grand Canyon is one of the most fascinating places on Earth. By going to the bottom of the canyon eight times and floating on the Colorado River four times, I have seen the history of change and its benefits to humans. I have also seen the harm that humans have inflicted on the Colorado River.

The Grand Canyon is not just one massive layer of rock. The canyon exhibits multiple layers of different kinds of rocks, and each layer has a different story to tell. At the bottom of the Grand Canyon, we see rocks forged in Earth’s creation. They are tilted and eroded with a layer of sedimentary rocks on top of the eroded surface. The sedimentary rocks contain the remains of creatures that lived in an ocean that once covered the region. One animal is the trilobite, similar to today’s horseshoe crabs. A layer of petrified mud called Bright Angel Shale rests on top of the sandstone, and Mauv Limestone covers the shale layer. Limestone is only deposited in deep oceans, so change was involved.

The sea became shallower for a while and then deeper again, indicating climate change. This deeper layer is called the Redwall Limestone, but the red is caused by iron minerals seeping from rocks above it. This limestone layer is 800 feet thick and is covered by the 700-foot-thick Supai formation, which contains corals, crinoids, and gastropods not seen in earlier layers.

With a warmer climate, the ocean became shallow enough that land plants could exist. More change happened, and the area became a desert, laying down the Coconino Sandstone. That layer contains frosted sand grains produced by high winds blowing the sand, which does not happen underwater. We can see lava flows on top of some of these layers, revealing the change produced by volcanic activity. Then, a shallow sea developed and got deeper, producing the Kaibab Limestone with many ocean creatures we don’t find in earlier layers.

Over time, a series of geological changes transformed the area we now know as the Colorado Plateau. These changes, including the uplift of the land and subsequent erosion, are what we see today in the Grand Canyon. They are a testament to the dynamic nature of our planet and the resources it has provided for human survival.

Some people suggest that Noah’s flood produced the Grand Canyon. They are ignorant of petrology – the study of rocks. The canyon is 278 miles long and gives a solid testimony to the patience and wisdom of God. Noah’s time was yet to come when all of these layers were deposited, and Noah’s flood is not recorded in the rocks or biology of ancient times. Saying that God created all of these layers and fossils to fool us makes God a liar, and James 1:13 says God never misleads us. Make sure the evidence supports your convictions – not unquestioning belief in denominational teachings or blind faith in chance as the causal agent for Earth and its amazing features and living things.
