The Origin of Life on Planet Earth

The Origin of Life on Planet Earth

When I was in college in the late 1950s, our biology professor at Indiana University gave us a nicely packaged explanation of the origin of life on planet Earth. In 1952, scientists Stanley Miller and Harold Urey built a test tube environment containing water vapor, methane, ammonia, and hydrogen, the gases Alexander Oparin and J.B.S. Haldane said would be needed for life to begin.

Miller and Urey used an electrical discharge to simulate lightning in the primitive Earth and placed a trap to collect any residue produced. After a time, they found the trap contained some amino acids, the building blocks of life. The media and our textbooks wrongly suggested that science had created life.

An old adage says, “Science education is the process of taking data from the professor’s notes and transferring it to the student’s test paper with as little interference as possible in between.” As a young atheist, I loudly proclaimed that it was impossible for an educated person to believe that God created life.

Nobody thought to question the assertion that the Miller-Urey experiment explained the origin of life on planet Earth. In fact, amino acids are not life, and life contains only specific amino acids. The Miller-Urey apparatus destroyed amino acids faster than it produced them, so the trap was necessary to prevent them from all being destroyed. The apparatus contained no oxygen, but in my geology class, we learned that there was much evidence for oxygen in the Precambrian rocks of the ancient Earth.

The quest to understand the origin of life (OOL) remains a topic of intense debate and exploration. In a recent publication in the esteemed journal Nature, researchers Nick Lane and Joana Xavier candidly acknowledged the persistent challenges in OOL research:

“The origins-of-life field faces the same problems with culture and incentives that afflict all of science—overselling ideas towards publication and funding, too little common ground between competing groups, and perhaps too much pride: too strong an attachment to favored scenarios and too little willingness to be proven wrong.”

Dr. James Tour of Rice University has called this area of research “clueless,” but the media continues to make unsupported claims. Perhaps the most crucial point of this research into the origin of life on planet Earth is that if science ever does discover the OOL, all it will show is that it took intelligence for it to happen in the first place.

We need Christian young people to go into science so they can explain false claims about OOL to those of us who may not have the inclination or the training to understand it solely by ourselves. However, we still need to educate ourselves enough to fulfill the admonition of 1 Peter 3:15, “Always be ready to give a defense to everyone who asks you a reason for the hope that is in you, with meekness and fear.”

Seeing God or Seeking God

Seeing God or Seeking God

We have often referred to Romans 1:19-20 which tells us that God can be plainly seen in the things He has made. However, skeptics frequently challenge us by saying, “If God is real, why doesn’t He reveal Himself?” They want to see God “in the flesh.” But God is not flesh and blood. John 4:24 says, “God is spirit…” Seeing God is just not possible.

God’s desire for us is to seek Him. As Paul shared with the pagans in Athens, God created us with a desire to “seek the Lord, in the hope that they might grope for Him and find Him, though He is not far from each one of us” (Acts 17:27 NKJV). The journey of seeking God is not only a path to finding Him but also a source of profound joy as we discover Him in the intricate details of His creation.

Suppose God appeared to us in all His glory. The Bible tells us that in our physical state, we could not stand to see His glory. Moses had to be hidden in the cleft of the rock to protect him from seeing God’s glory. We can’t understand how that sight could have been too much for Moses’ feeble eyes to behold. However, Moses could see God’s work, just as we can.

God loves us and wants us to love Him. If we could see God, would we be terrified? Would we obey God’s commands out of fear rather than love? Fear is a powerful motivating factor, but God wants our love. God showed His love in the form of a physical person, Jesus Christ. Jesus was God, but He was also human. He was Immanuel, “God with us” (Matthew 1:23). He said, “He who has seen me has seen the Father” (John 14:9). Jesus was not hidden, but many people refused to see who He really was despite His miracles. (See John 19:16.)

Seeing God in His full glory is not something we will experience in this life. However, we can find immense joy in seeing His handiwork. If God were to fully reveal Himself before our eyes, our physical beings would not be able to withstand His glory (Exodus 33:20). If we somehow managed to survive, our service to Him would be driven by fear and terror, not love. We would lose the joy of discovering Him in His works. The experience of physically seeing God, even if possible, might be overwhelming. On the other hand, finding God in the things He has made is a delightful experience, akin to a child’s delight in finding the one they seek in a game of hide-and-seek. May we all discover that kind of joy as we earnestly seek and find God.

Mutualism Shows Life Design

Mutualism Shows Life Design - Nitrogen-fixing nodules on legume roots
Nitrogen-fixing nodules on legume roots

We call it mutualism when various complex relationships occur between two species, producing codependency and benefits to both. There are two kinds of mutualisms. In obligate mutualism, both species depend on each other for survival. Facultative mutualism refers to relationships that benefit the species, but they could survive without it. Looking at life on Earth, we see many examples of how mutualism shows life design.

In Borneo, a carnivorous pitcher plant and wooly bats have a relationship of obligate mutualism. The plant lures bats in with an echo reflector, but the plant doesn’t eat the bat. The pitcher plant grows in soils with low nutrients and needs additional fertilizer. The droppings of the bats provide that fertilizer, enabling the plant to survive. The woolly bats are easy victims of predatory animals, but during the daytime, when the bat isn’t hunting insects, it finds refuge and protection inside the pitcher plant. The plant and the bat depend on this relationship, but no one would suggest they are related.

Legumes such as beans, peas, and clover form a mutualism with bacteria. The bacteria can fix nitrogen from the atmosphere, turning it into ammonia. The plants use the nitrogen from the ammonia to synthesize proteins needed for growth. The plants serve the bacteria by housing them in root nodules and providing them with sugars and oxygen so they can grow. Once again, mutualism shows life design.

There are a vast number of smaller organisms that depend upon obligate mutualism. An example is a green-brown spongy sludge that grows on the marshes of the Florida Everglades. It may look like a toxic algal bloom drawing oxygen from the water. But instead of being destructive, it is a mutual design of algae, fungi, microbes, and bacteria. This perfectly matched relationship is called a periphyton. It is a system of life that provides the basis for the entire food chain of the Everglades and another example of how mutualism shows life design.

Trying to explain how mutualism became part of Earth’s living systems by a chance process takes a huge imagination and a great deal of faith. It seems far more likely that mutualism is not an accident but part of God’s design for life. The more we know of the creation, the closer we get to the Creator.

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).
