Alligator Brumation in Cold Weather

Alligator Brumation in Cold Weather

One of the amazing examples of design in the animal world is how alligators survive weather cold enough to cover their ponds with ice. Warm-blooded animals (endotherms), such as bears and groundhogs, hibernate in cold weather. Cold-blooded animals (ectotherms), such as alligators, become dormant using different metabolic processes. It is called alligator brumation.

The Swamp Park in Ocean Isle Beach, North Carolina, has made videos of alligator brumation. The alligators put their snouts out of the water, and their metabolic rate slows as they become lethargic. One park employee said, “We literally have gatercicles.” In Beaumont, Texas, there are some 550 alligators, including one 92-year-old that is 13 feet long and weighs over 1000 pounds. When his pond begins to freeze, he lets the ice freeze around his nose.

The design of the alligators’ body and metabolic structure allows them to survive in a temperate climate. It may not be obvious to most of us that alligators have an essential role in swamp environments. In the swamps in the southeastern part of the United States, they maintain a balance that benefits many other forms of life. As scientists try to understand that balance and how human encroachment affects it, the brumation system is essential.

Every form of life and ecosystem has a design that allows wise engineering. Cases like alligator brumation are amazing and speak of having been created with a particular need in mind. The more we know of the creation, the better we understand the mind and wisdom of God.

Design of the Umbilical Cord

Design of the Umbilical Cord

Science still doesn’t fully understand the design of the umbilical cord that allows a baby to live inside its mother for nine months. The umbilical cord supplies the baby with oxygen, nutrients, and antibodies. Birthing techniques before the 20th century delayed cutting the cord, but that has changed since birthing moved from the home to the hospital. However, new data shows that delaying cutting the umbilical cord can boost the baby’s blood volume, red blood cell count, and iron stores and ease the transition to breathing.

The issue of when to cut the umbilical cord has become exceptionally well-studied in the case of premature babies. Nearly one million premature babies worldwide die every year, and a study of 10,000 preemies shows that when doctors delay clamping and cutting the umbilical cord, the survival rate improves. Yale University School of Medicine expert Jessica Illuzzi says, “longer is better.” The design of the umbilical cord is amazing.

Some pro-abortion advocates say the unborn child is just an extension of the mother’s body. It can be cut off and discarded like a fingernail or a lock of hair. There is no scientific support for such a claim. From the mother’s morning sickness to the baby’s physical characteristics and genetic makeup, all evidence shows the child is a unique individual. The fact that the unborn child depends for survival on the mother and the design of the umbilical cord does not change the fact that the baby is a unique human and not part of the mother. Every facet of the reproductive process shows God’s wisdom.

Women have the right to choose whether to be a mother, but the decision must be made before sexually engaging with a man. In the case of an unwanted pregnancy, options are available. As the father of three adopted children, I know how that adoption can be a positive experience for everyone involved, and there is an acute shortage of babies for adoption.

The psychological damage of abortion for women is well documented. Part of that damage comes from knowing that a child created in God’s image has been destroyed. The system of producing life designed by God has been disrupted, which is an affront to the Creator.

Elephantnose Fish Designed for Survival

Elephantnose Fish Designed for Survival

We can see evidence of a creator in the design features of living things that allow life to flourish in hostile environments. One of those environments is the very muddy rivers in Western and Central Africa. They are so muddy that underwater visibility is less than an inch. How do fish find food and avoid obstacles in muddy rivers like that? Peters’s elephantnose fish have the answer.

Peters’s elephantnose fish (Gnathonemus petersii) have an electrolocation system. An organ on their tails sends out weak electric field pulses. Receptors on the fish’s skin detect distortions to the field caused by any object or creature nearby. The fish also has a trunklike nose, which is full of electroreceptors. Peters’s elephantnose fish can make unusual movements to catch prey or avoid objects. It can even paddle backward in what researchers call a “moonwalk.” 

Researchers have found that by swiveling the trunklike nose (called a schnauzenorgan) and shaking the electrically-charged tail, a Peters’s elephantnose fish can create a mental 3-D map of its environment without seeing it. Experiments have shown that this system is very accurate and efficient. In one test, the fish could identify a shape and correctly respond to that shape 94% of the time.

We suggest that such a unique design seen in Peters’s elephantnose fish gives strong evidence that life is not an accident. The evidence indicates it was designed by an intelligent Creator to allow every part of our planet to be inhabited by unique forms of life, even places that would be lethal to most life forms. This doesn’t happen by accident but rather by the God who created life. We can study and learn about the Creator because He created us in His image and shows Himself to us in the things He has made (Romans 1:20).

Lunar Cycles, Lunar Influence, and Lunacy

Lunar Cycles, Lunar Influence, and Lunacy

The Latin name for the Moon is “luna.” Many English words are derived from that root, including lunacy, lunatic, and even loon, as in “crazy as a loon.” Having grown up in the north, I know that hearing the cries of loons could lead to thoughts of them being crazy. Lunar cycles occur naturally, but many people believe a “lunar influence” is connected to abnormal behavior.

People have given unique names to certain full-moon appearances, such as blue moon, sturgeon moon, harvest moon, cold moon, snow moon, pink moon, flower moon, strawberry moon, hunter moon, beaver moon, worm moon, and wolf moon. You can find those names in the Old Farmer’s Almanac, so it should not be surprising that most of them have connections to agriculture or to a time when people did not have electric lights clouding their view of the sky. I have found that seeing the full moon in remote areas hundreds of miles away from city lights is a moving experience. If you were fishing, harvesting, hunting, or plowing, you would have no problem with just the Moon for illumination.

The Moon is not just an accident, nor is its influence on life. Genesis 1:14 describes God clearing Earth’s cloud cover to let the lights of the heavens (Sun and Moon) become visible “for signs and seasons and for days and years.” Some birds use the Moon for migration journeys that coincide with specific lunar phases. Many animals respond to both circadian rhythms and a lunar clock.

So, how does the Moon affect human activity? Studies show that there are more animal bites from cats, rats, and horses during full moons. That is probably because more humans are doing more things outside at night during a full moon. Also, data show there are more crimes during full moons. Apparently, criminals can use the light of a full moon for their activities just as farmers can.

The Bible refers to lunar cycles for time and mentions lunar festivals (Colossians 2:16) but otherwise makes no particular connections to the Moon. All of the claims of abnormal human behavior during various lunar cycles are in the realm of what is called “folklore.”

I hope you can take some time to admire the full moon away from city lights and imagine how ancient people depended on it for nighttime light to carry on their lives. Meanwhile, don’t worry about it affecting you psychologically or causing biological changes. The animals and insects may be altered by lunar cycles, but you are not a bug or a werewolf.

Star and Planet Formation

Star and Planet Formation and the Webb Telescope
Webb image of the Tarantula Nebula star-forming region

Yesterday, we discussed the new information about the construction and size of the cosmos we are learning from the James Webb Space Telescope. The Webb telescope shows us the size of God’s physical creation as NASA continues to pump out new discoveries and better understandings of star and planet formation. Search “James Webb Telescope” on your computer and see for yourself.

One of the better understandings from recent Webb telescope data is what it takes to make a planet like Earth. The conventional understanding of planet formation was that as stars formed, they threw off material that gravity pulled together, forming planets. The Webb telescope has the resolving power and the infrared light-gathering ability to observe planet formation in different stages.

The first step in planet formation is for the star to actively produce elements needed for terrestrial planet formation. Quiet stars do not make the necessary elements since heavier elements will move toward the star’s center, not outwards. The star must spin fast enough to throw out the required heavy materials. That means gaseous planets like Jupiter are much more common in the cosmos than terrestrial planets like Earth.

The heavier elements in a planet come from exploding stars. That means planets will be more likely in certain types of galaxies, and galaxies have an evolutionary history, changing with time. The Webb telescope actually observes the changes in galaxies and star and planet formation. The creation process is still active, and new planets are being formed as we watch.

In manufacturing, we know that a machine is designed to take raw materials and mold and shape them into the desired final product. Years ago, I worked for a man who designed and built such machines, and his wisdom and creativity were incredible to watch. This designer didn’t use a blueprint or follow a manual. He had the skill to comprehend what the final machine would look like and what it would do.

As we watch star and planet formation take place, we see the wisdom and creativity of God. The writer of Proverbs wrote, “O you simple ones, understand wisdom and you foolish ones, be of an understanding heart” (Proverbs 8:5). The Webb telescope allows us to see the wisdom of the Creator in ways we have never imagined.

What We Learn from the Webb Telescope

What We Learn from the Webb Telescope

With all the distractions going on in the world, it is easy to miss perhaps the most remarkable engineering accomplishment of human history. A telescope launched on Christmas Day 2021 is now much further from Earth than the Moon is. The Webb Space Telescope consists of 18 hexagonal mirrors with a total area of 273 square feet (69.54 x 46.46 feet) and can see things in space that can’t be viewed from Earth’s surface. The cost to make the telescope and place it in space was 10 billion dollars, so is it worth the price? Yes, it is! What we learn from the Webb telescope tells us more about God.

More than 40 years ago, J.B. Phillips wrote a book titled Your God is Too Small. The first thing we learned from the Webb telescope is that the cosmos is much bigger than we can imagine. The telescope can see things that no optical device on Earth can. We live in a galaxy containing roughly 100 billion stars, and we know there are many other galaxies in space. Webb has shown us vast numbers of distant galaxies, and as we measure how far away they are, we see what the creation looked like billions of years ago.

Let me give you a simple explanation of what that means. If you travel to a place 100 miles away at 50 miles per hour, how long will it take to get there? The answer is two hours. When we measure how far away these galaxies are, we can tell when the light we see left them. Light travels at 186,000 miles per second. Doing the same calculation, we know the light reaching the Webb telescope left those galaxies some 13 billion years ago. We are looking backward in time to near the beginning of creation.

The latest pictures from Webb show that these old galaxies are flat like a sheet of paper. We learn from the Webb telescope that the creator was molding and shaping galaxies into a form that would allow planets and, ultimately, life to exist. As we understand the creation process, we see power beyond what we can imagine. Like all scientific discoveries, that raises many new and exciting questions for us to study and understand. It further tells us how unique Earth is and raises an old question the ancients asked about God, “What is man that you are mindful of him” (Psalms 8:4).

What Is Gravity and How Does it Work?

What Is Gravity and How Does it Work?

Many things in the creation do not lend themselves to conventional science. Gravity is an excellent example. What is gravity, and where did it come from? Issac Newton suggested that gravity was a property of mass because the more mass something has, the more it weighs. A physics equation describes gravity, saying that if you have two masses, there will be a force of attraction between them.

In a high school physics experiment, we hung two large bags of sand near each other. Gravity would pull them toward each other, and if you increased the amount of sand, it would draw them closer. Using a group of levers, the students could measure the force between the two bags. We can measure it, but what is gravity?

Instead of bags of sand, scientists measure the gravity force between the Earth, Moon, and Sun. What keeps Earth orbiting the Sun and the Moon orbiting the Earth? Isaac Newton proposed that the distance between objects affected the amount of gravitational force between them. An equation describing the attraction between masses 1 and 2 must include the masses, the distance between them, and a number known as the gravitational constant. The equation is F = G (M-1)(M-2)/X2. G is the gravitational constant, and scientists have measured it to be 6.67 x 10 -11. If the value of the constant G differed from what it is, the Earth could not exist, and neither could we.

If you don’t follow all of that, don’t worry about it. The point is that gravity is a complex quantity that holds everything together. But that leaves questions unanswered. What is gravity? Is it a wave? How can it work over huge distances? How can mass cause gravity – or does it? Why is the gravity constant precisely what it is?

As science probes deeper into the nature of matter, time, space, and energy, it becomes increasingly evident that not everything physical has a physical cause. We cannot explain the creation of time, space, energy, or gravity by conventional science. As you read modern research reports, you see that our world was shaped from dimensions beyond the four we know about. The laws that govern our world and the dimensions we live in do not fully describe the nature of gravity, time, or even space.

Ancient biblical writers guided by the Spirit of God understood that a wise Creator designed our world. The writer of Proverbs 8 personifies wisdom, giving it a feminine nature. Wisdom says, “O you simple, understand wisdom and have an understanding heart. The Lord possessed me in the beginning of His way before His works of old. I was set up from eternity, from the beginning and before the earth ever was.”


Open-minded contemplation of the creation leads to the recognition that an infinite intelligence beyond that of any human brought the physical creation into existence. We learn from the Bible that God’s purpose was to allow the war between good and evil to end once and forever and that we play an essential role in that war.

Extinction of Plant and Animal Species

Extinction of Plant and Animal Species
Illustration of Woolly Mammoths

Near the end of 2023, the U.S. Fish and Wildlife Service removed 21 species from the Endangered Species Act because they have become extinct. What causes the extinction of plant and animal species?

Many factors lead to extinctions. Dr. Hugh Ross says the fossil record indicates that half of the mammal species that existed at the time of Adam and Eve are now extinct. Human activities that can endanger species include habitat destruction, introduction of invasive species, and introduction of diseases. Of course, animals can endanger people in various ways, including introducing diseases.

Humans have endangered plant species by introducing invasive plants. Plants used for decorative purposes can become invasive. Examples are English holly and the tree of heaven. Some plants that have become invasive were introduced to serve a purpose, such as controlling erosion. An example is the kudzu plant.

At other times, humans have caused extinction by killing large numbers of a species such as the passenger pigeon. Because of hunting and habitat destruction, the dodo bird became extinct within less than a century of its discovery. Humans caused the extinction of the great auk by foolish vandalism. Today, poachers are endangering the rhinoceros by killing them for no good reason. By contrast, human efforts rescued the California condor after it became extinct in the wild.

Woolly mammoths existed alongside early humans, and some scientists say they were essential for the survival of humans in some areas. People used them for food and their skins for protection from the elements. Their bones became tools, building materials, and even musical instruments. These large animals also kept plant vegetation under control while spreading their seeds. We can not always determine the cause of the extinction of plant and animal species, and that is the case with woolly mammoths.

The extinction of the dinosaurs occurred before humans were on the scene. That is good because humans and dinosaurs could not coexist on the land or at the same atmospheric oxygen level. God used them to prepare Earth for humans, and He orchestrated their extinction before He placed Adam and Eve in the garden.

As we look at the extinction of plant and animal species, we learn some essential facts. From the beginning, God had a plan for life as He prepared this planet for us to be here. He gave the first humans the responsibility to take care of the Earth, but we have not done a very good job. Finally, God is still giving us a chance to do better, and we have had some successes. Serving God involves serving others and caring for what God has given us for human flourishing. We can only do that when we submit to His plan for our lives.

Survival in the Cold by Design

Survival in the Cold by Design
Chickadee in Winter Snow

As I sit in my warm office in Michigan today, I look out at snow and ice. My outdoor thermometer registers -8 degrees, and I wonder how the ducks on the river, the squirrels on the ground, and the birds in the air handle these frigid temperatures. I enjoy watching the birds on my bird feeders and the squirrels chasing each other in the oak trees, but I wonder how they survive. Then I apply my knowledge of physics, and I understand animal survival in the cold.

I always enjoyed teaching the heat and thermodynamics section of my high school physics class. One of my lines that always got a laugh was, “Why do we need to wear clothes to survive, outside of the obvious one.” The point is that our skin is not very good insulation against the cold. In winter, we pick clothes with air spaces within the fabric because air is a very poor conductor of heat, so it insulates us from the cold. We use coats stuffed with goosedown or some facsimile to be well protected from the cold. Goosedown also insulates sleeping bags and quilts.

Chickadees visit my bird feeders regularly. They usually are relatively sleek birds that fly smoothly and efficiently. As I look at my chickadees on this day of -8 degrees, they are almost round. Their feathers are fluffed up to trap air, so the birds are well insulated for survival in the cold. They don’t fly as smoothly as they do in summer. They crowd my feeders and would sit there without moving if they could.

Squirrels have a different problem. Their coats give them some protection, but getting food is an issue when heavy snow covers everything. They need to keep warm but avoid activities that would sap their reserve of nutrition. My gaze goes to the top of the oak trees, and I see a large round ball of leaves and twigs. Many years ago, to expand our church parking lot, we had to take down a tree with a large round ball of leaves and twigs near the top. As the tree came down, a squirrel ran out of the ball. I put my hand into the nest to see what was inside. Even though the air temperature was 20 degrees, it was very warm inside the ball of leaves and squirrel hair.

God has equipped His creatures for survival in the cold, and His design enables our Michigan winter to throb with animal activity. Trial and error explanations are weak because survival errors are lethal. We can see design in the natural world that speaks of God’s wisdom and planning. The evidence allows us to “know there is a God through the things He has made” (Romans 1:20). Watching animals thrive in very cold conditions is an excellent example of that evidence.

Why Women Have to Experience Menopause

Why Women Have to Experience Menopause

We get some interesting questions in this age of skepticism and rejection of God. One that came up recently is why women have to experience menopause. Like many questions raised by those who wish to deny God’s existence, this question is rooted in ignorance and a failure to think carefully.

Most members of the animal kingdom die when they can no longer reproduce. Mammals such as elephants and orangutans remain fertile throughout their lives. The number of animals that live beyond their reproductive years is very small. It has only been documented in a few species, including humans, orcas, and short-finned pilot whales.

There is no scientific explanation for the uniqueness of the human reproductive cycle. Dr. Shankar Singh of McMaster University in Canada maintains that this is because men favor younger mates, but this evolutionary explanation ignores the genetic implications that come with it. The more logical explanation of this fact is the different roles women have at various stages of life. In Titus 2:1-5, Paul talks about older women teaching younger women.

As we get older, our roles change. There is a reason for humans to live beyond the time when they can produce offspring. Teaching, leading, and serving can be more effective when done by older humans. That is not true of fish, birds, rodents, insects, or most mammals.

It is a good design that older women can no longer reproduce. My 70+-year-old wife says the thought of having a baby at her age is appalling. For orangutans and elephants, a female having offspring late in life helps maintain the species, and the whole group raises offspring, not just the mother.

Instead of asking why women have to experience menopause, we should note that God’s remarkable design of reproduction uniquely shows His handiwork.
