The Beautiful Ugly Opossum

The Beautiful, Ugly Opossum

Perhaps you have seen this animal prowling your neighborhood and looked at the ugly opossum with disdain. When Captain John Smith of the Jamestown Colony in Virginia first saw an opossum in 1611, he described it as a cross between a pig, a rat, and a cat. Although people often consider them unattractive, we appreciate the beautiful, ugly opossum design as they serve a unique purpose in America.

Opossums are the only marsupials in North America. Like kangaroos and other Australian marsupials, opossums birth their young shortly after conception. The newborn must find its way into the pouch, where it will nurse for up to four months before emerging.

Opossums have 50 teeth, allowing them to eat just about anything. Their omnivorous diet includes rodents, frogs, birds, eggs, insects, fruit, and grain. They will eat dead animals, including the bones, and they remove pests from our gardens. They don’t burrow, and unlike raccoons, they are not dexterous enough to get into trash bins or your house or garage by digging into a wall or roof. Although people often describe opossums as ugly, they are among our best animal friends.

Opossums are nocturnal
, so we rarely see them except when they get hit by a car. They are not aggressive, and when frightened, they often play dead. Their low body temperature of 94 degrees (F) prevents them from getting rabies and other viruses, and they are not affected by snake venom.

The beautiful, ugly opossum is part of God’s design for life on this planet. All animals serve a purpose in the natural world, but we often vilify opossums because of their appearance, not realizing the ways they benefit us.

Ice Worms and Ooligans

Ice Worms and Ooligans

The National Park Service website has a page on ice worms that live in the glaciers of the Pacific coast of North America. This reminds me of a children’s book by Charlsey Ford that we published in 2005. Charlsey worked with us for many years in our efforts to show that science and faith are symbiotic and not adversarial. Charlsey’s book Animals of the Cold was illustrated by John W. Davis III and Alyssa Cain. It shows that God has placed life, such as ice worms and ooligans, even in the most hostile locations on Earth.

Tiny ice worms live in colonies of thousands in a square meter of a glacier. According to the National Park Service, they are so well suited for the cold that they will “melt” at room temperature as their cells become liquified. Ice worms live in tunnels in the glacier ice and eat algae, bacteria, pollen, and dust that falls on the glacier. Ice worms produce soil that allows plants to grow in a desolate place. Birds such as the snow bunting feed on the worms. Being at the bottom of the food chain, ice worms provide the basis for life in glaciated areas.

The ooligan is another life form uniquely designed to live in very cold climates. Ooligans are sometimes called “candlefish” because they contain so much oil that if you dry the fish and light a wick in its mouth, it will burn like a candle. Native people in the Bering Sea area have used ooligans for centuries as food and medicine. Ice worms and ooligans are two of the beautifully designed organisms that allow life to exist in extreme environments.

Life on planet Earth fits well with the words of Romans 1:19-22 which tells us we can know there is a God through the things He has made. From deserts to dark, deep ocean habitats, we can see that a wonder-working hand has gone before.

Plants Use Frogs to Spread Their Seeds

Plants Use Frogs to Spread Their Seeds

One evidence that God and not chance created all living things is the varied ways plants get their seeds into new places. A recent study of frogs at the University of Newcastle in Australia has shown that plants use frogs to spread their seeds. This comes as a surprise since frogs are primarily carnivorous, but frog skins attract seeds and can carry them considerable distances.

The researchers found that tree frogs can carry as many as 14 seeds on their legs, feet, bellies, and backs. Some of the seeds found on the frogs they studied did not grow in the area where the frogs live, so they were picked up somewhere else. We have pointed out that birds spread seeds. Wading birds will have fish eggs stuck to their feet and legs, so fish will appear in recently dug ponds where humans have not placed them.

The studies in Australia have raised concerns over the loss of amphibians due to pollution and habitat destruction. It isn’t just losing the frogs at issue, but also the function of frogs in supporting plant life. Plants use frogs to spread their seeds, allowing plants to move into areas that need plant cover.

Everywhere we look, we see multiple designs offering complexity that cannot be produced by chance. There is intelligence in the creation, and one place we see it is in the role of all life on Earth.

Reindeer Eyes Designed for the Arctic

Reindeer Eyes Designed for the Arctic

The eyes of reindeer, also known as caribou, are different from those of any other mammal. The retinal tissue known as tapetum lucidum in reindeer eyes changes color from gold in the summer to vivid blue in the winter. Many nocturnal mammals have this mirror-like layer that reflects light, causing “eye shine” and allowing the photoreceptors to sense dim light. Only in reindeer eyes does it change color with the seasons.

Lichens are a main staple of the reindeer diet and are very common in northern latitudes where reindeer live. A lichen known as “reindeer moss” is an off-white color, making it difficult to see in the snow. However, snow reflects ultraviolet (UV) light, and the lichen absorbs it. The changing color of the retinal tissue is designed to make the lichen stand in dark contrast to the white snow.

UV light damages the eyes, so the cornea and lens suppress the UV radiation in most animals. Some of us have experienced temporary snow blindness caused by UV light, and excessive exposure can lead to cataracts. However, reindeer eyes are designed to admit up to 60% of UV light. Reindeer moss has “impressive antioxidant properties,” which may help prevent UV light damage. Also, reindeer feed on the buds and leaves of Arctic willow and dwarf birch, which have high levels of Vitamin C (ascorbic acid), which helps repair damaged cells.

From September to April, animals such as reindeer living above 70 degrees latitude experience the violet-blue of twilight for 8-11 hours daily. Reindeer eyes display another example of a specialized design unique to one species, giving the animal tools for survival in its environment. Predatory white wolves are well camouflaged in the snow but appear relatively dark to a reindeer detecting UV light.

The color-changing tapetum, unique to the reindeer species, is difficult to explain by gradual chance mutations. We suggest it is another example of how God has produced special equipment to enable an animal to survive in a challenging environment.

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.

Basal Cognition in Living Cells

Basal Cognition in Living Cells

Flatworms called planaria live in the muck of lakes and ponds worldwide. Scientists are intrigued by the fact that if you tear the worm in half, its head will grow a new tail, and its tail will grow a new head, giving you two worms. A new field of science involves the study of basal cognition in living cells outside of the brain.

Many years ago, I was involved with a project that attempted to fight the presence of invasive lampreys in the Great Lakes. Lampreys are eel-like fish that swim up tributary rivers to spawn. We placed barriers on streams to catch and kill the lampreys. The problem was that those who worked the lamprey traps were told to cut the eels in half and throw them back in the river to avoid the stink and mess of dead eels on land. They didn’t understand that returning the eels to water doubled their population because both halves survived.

In the case of the planarian, researchers at Tuft University found that the worm not only survived, but the tail contained previous memory. Both the head and tail of the worm remembered the location of a food source learned before the worm was cut in half. Michael Levin at Tufts has shown that cells can use subtle changes in electric fields as a kind of memory. This basal cognition in living cells works using electrical signals in animals and plants.

Scientists have found basal cognition in the Venus flytrap and the touch-me-not plant. The touch-me-not leaves will fold and wilt if touched to prevent being eaten. Scientists found that if the plant is jostled throughout the day without being hurt, it will learn to ignore jostling. The Venus flytrap can count, snapping shut only if two of the sensory hairs on its trap are tripped in rapid succession. It pours digestive juices into the closed trap only if sensory hairs are tripped three more times.

RNA seems to be a medium of memory storage for cells. Taking RNA from a slug that had experienced an electric shock and injecting it into a new slug causes the new slug to recoil from the touch that preceded the shock in the old slug.

This research shows that intelligence does not always require a brain but is wired into all living things and is vital to all life. The practical use of these discoveries of bioelectricity may help treat cancer where cells are not cooperating with the rest of the body. God’s design of life is far more highly engineered than anyone suspected. We have a lot to learn about basal cognition in living cells.

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).

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.

Bristol Bay and God’s Design

Bristol Bay and God's Design
Bristol Bay

There are many fascinating facts about Alaska. One of them is how landlocked species of fish, animals, and plants receive the required nutrients. With the weather extremes, short growing season, and lack of soil, making the area biologically rich requires an extraordinary life form. Fishing lodges thrive throughout the Bristol Bay area because sport fishers consider it one of the most desirable places to catch wild salmon and trout. In addition to the sport fishing, native people and commercial fishing operations make a living in the Bristol Bay area. Both humans and wildlife in the area depend on one fish species, the red salmon, or as it is also known, the sockeye.

More than 60 million wild salmon pour into Bristol Bay every year, sustaining the wildlife and human economy. Sockeye eggs provide food for all five species of Pacific salmon, but they also allow the land-locked species Arctic char, Dolly Varden trout, and rainbow trout to exist. The fry, smolts, and adults support commercial and subsistence harvesting.

The total mass of sockeyes each year is in the millions of tons. After the sockeyes have spawned, they die, and their carcasses provide nutrients that allow plants to thrive in an area with very little soil. Without the sockeye, the entire Bristol Bay area would be a biological desert unable to support any fish or animals that eat fish.

Mining operations are trying hard to get permission to establish several kinds of mines in the Bristol Bay region. Undoubtedly, such operations would create roads capable of hauling metals, mining equipment, chemical leaching, and waste materials. Supplying food and managing waste from hundreds of miners and support personnel living in the Bristol Bay area for years at a time could destroy the fragile ecosystem, harming those who depend on it. The more scientists study the ecology of Alaska, the more they become aware of its fragility.

Bristol Bay speaks of our need to care for the creation that God has placed in our hands. It is hard to experience this area and believe its formation and natural balance happened because of blind, accidental chance. We must not allow it to become a showcase for selfish human greed and mismanagement.
