Left-Handedness of Proteins and Amino Acids

About 9.2 percent of people are left-handed. In other words, less than 10 percent of humans exhibit left-handedness. However, the proteins in living organisms are 100 percent left-handed. I know proteins don’t have hands, but using the term “handedness” helps to explain how proteins are structured. Proteins are made from amino acids, which fold into left-handed shapes that enable their functions in living beings. These proteins are composed of amino acids, which are also left-handed.

This handedness is more accurately called “chirality.” There are over 500 different amino acids, and they exhibit both left and right chirality. However , only 22 of them are used to make proteins, and their chirality is all left-handed. This creates a mystery. If amino acids existed on early Earth in equal amounts of right- and left-handed forms, and life requires only left chirality, how could life have formed spontaneously? Some thus-far unexplained force would have to select only left-handed amino acids to come together to get life started. Robert F. Service, writing on science. org, called this “an enduring mystery.”

Scientists have proposed several ideas to explain why proteins are left-handed. Some suggest meteorites delivered left-handed amino acids to early Earth. It appears that meteorites are rich in these amino acids, likely due to exposure to polarized light. Another hypothesis is that magnetic fields on early Earth twisted the biomolecules. Robert Service asks, “But even if some external force imparted an initial bias, what propagated it?”

Gerald Joyce, a chemist specializing in the origins of life and president of the Salk Institute for Biological Studies, said, “Perhaps it was just a statistical coin flip that caused an original bias toward building blocks of one-handedness to form. But once that coin flipped, it caused other coins to flip.” Those of us who believe in a Creator are often accused of using a “God-of-the-gaps” explanation for life’s mysteries. To me, this explanation for the left-handedness of proteins sounds like a “coin-flip-of-the-gaps.”

Axolotls, or Mexican Salamanders

Axolotls, or Mexican Salamanders
Axolotls, or Mexican Salamanders

People often call them Mexican walking fish, but they are not fish. They are amphibians, specifically salamanders. Axolotls (Ambystoma mexicanum) or Mexican salamanders look like a fish because it never fully leaves its larval stage.

Unlike other salamanders and frogs, axolotls do not go through metamorphosis. When they become adults, they still look like tadpoles. They develop tiny legs but keep their gills instead of growing lungs and moving to land. The external gills and caudal fin, which are usually only found on salamander larvae, give axolotls a fish-like appearance.

Genetic differences lead to four color variations, from black or olive to pale pink or gold. They eat insects, worms, and small fish by sucking food into their mouths like a vacuum cleaner. In the wild, they are critically threatened and close to extinction because their last native habitat, Lake Xochimilco, is being overtaken by urban growth from Mexico City. However, many of these salamanders are bred in captivity as exotic pets and for research.

Axolotls are valuable for studying heart and nerve functions. They have an incredible ability to heal themselves, capable of regenerating severed limbs and some internal organs. Their injuries heal without leaving scars. Axolotls can also accept transplants of organs, eyes, or even brain parts without rejection issues.

Scientists study axolotls to discover new secrets of healing. God has given us many resources in the natural world and the ability to learn from them. As we have said many times, science and faith are friends, not enemies.

What Makes Humans So Special?

What Makes Humans So Special?

Many animal rights advocates argue that we should treat animals the same as humans. To do otherwise is what they call “speciesism,” and they consider it perhaps even worse than racism. Why should humans be favored over other species? What makes humans so special?

An article in Scientific American caught my attention. It was written by Kate Wong and titled “Humans Are Not So Special After All.” The article points out that since 1960, when Jane Goodall observed a chimpanzee using grass and twigs as tools to coax termites from their nests, people have discovered that animals can do things previously thought only humans could do. Wong suggests that humans are not unique and that even plants can think and count.

Observations have shown that animals can perform amazing feats, but isn’t it possible that they do these things because they were programmed for survival by their Designer? It seems to me that the examples Wong provides fall short of proving her point. What makes humans so special involves more than the intelligent actions animals perform.

One example Wong uses is that brown capuchin monkeys decline a treat when they see another receiving a better one. She claims this shows a “sense of fairness,” but couldn’t it also indicate a sense of greed? She states that apes, monkeys, and elephants “mourn the loss of bonded individuals.” However, those species are programmed with a group/herd mentality that depends on each other for survival. She also mentions how mice and rats are affected by the pain or suffering of a fellow species member; but rather than compassion, could that not be fear for their own safety?

Wong also mentions an orca that made worldwide headlines for carrying her dead calf for 17 days while swimming 1,000 miles. To me, that appears to be a programmed survival instinct that failed to recognize there was no hope for the calf’s survival. The Eurasian magpie that “recognized itself” in a mirror reminds me of a turkey rooster that “recognized” his reflection in my basement window and kept tapping on the glass to challenge this supposed “competitor” for his territory.

For an example of plant “consciousness,” Wong presents the Venus flytrap and the fact that it “remembers” being touched. After two touches, it closes to trap the insect. After five touches, it secretes enzymes to digest the prey. But this does not demonstrate “thinking.” It is very simple to program a counting subroutine that causes a device to perform an action after two, five, or any number of signals from an outside source. That is programming, not thinking. The same applies to plants that produce chemicals summoning predators for defense when an animal chews on them. Again, it seems to be a survival program built into the plant.

Wong mentions anthropomorphism as “ascribing human thoughts, feelings, and motivations to animals.” While that is something people often do—particularly with dogs—I think Wong herself may be guilty of it.

The bottom line is that none of the examples Wong cites can compare to what makes humans so special. Humans alone are created in the image of God. We have minds unlike the brain functions of any animal. When we see animals do amazing things, we should give credit to the Creator who gave them those survival abilities.

Why Are There So Many Species?

Why Are There So Many Species of Life?

How many species of living things exist? So far, scientists have identified, classified, and named 1.2 million species, according to worldatlas.com. The same source states there are about 8.7 million species on Earth. Nobody knows for certain, but other estimates—excluding viruses and bacteria—range from 10 million to 100 million species. Why are there so many species of living things?

How quickly are scientists discovering and describing new species? According to worldatlas.com, they identify and assign genus and species names to 15,000 to 18,000 new species each year. At that rate, if we assume 1.2 million have already been named and there are 10 million in total, the task will take over 500 years, but that’s a conservative estimate. Clearly, biologists still have a lot of work ahead.

There are between six and seven thousand known mammal species according to ourworldindata.org, . But the insect world surpasses that number. For example, beetle species alone number between 350,000 and 400,000. Each year, biologists identify most of the “new species” from museum specimens discovered earlier but not carefully studied. Some species in the wild are facing extinction, and some specimens in museums may already be extinct.

We may ask, “Why are there so many species?” God created diverse kinds of living things and endowed them with the ability to adapt to different environments. Each new species fills a niche in the incredible diversity of animal and plant life that makes our existence possible.

We have previously described the various taxonomic classifications used to categorize living things. (You can read that HERE.) “Species” is the lowest and most specific taxonomic category used by scientists to describe life forms. God created humans with an insatiable curiosity and an amazing ability to organize and categorize information. Then, He gave us plenty of life forms to study. We believe that we can learn more about God as we explore His creations. (Romans 1:20)

Honey Is a Wonderful Gift

Honey Is a Wonderful Gift
Honey Is a Wonderful Gift

Honey is a wonderful gift from God, who created the agents that produce this amazing substance for our benefit. It has been a food source for people throughout history, but it is more than just food. Honey offers many health benefits, serving as an antidepressant, anticonvulsant, and anti-anxiety remedy. It has also been shown to improve memory disorders, heal wounds, and reduce allergy symptoms.

Honey is mentioned 61 times in the Bible. When God called Moses to lead the Israelites out of slavery, He described the land as “a land flowing with milk and honey” (Exodus 3:8). John the Baptist lived on locusts and honey (Matthew 3:4 & Mark 1:6). When Solomon wanted to describe the beauty he saw in his lover, he said, “Your lips drop sweetness as the honeycomb, my bride; milk and honey are under your tongue…” (Song of Solomon 4:11).

The agents God created to produce this wonderful substance are bees. It takes twelve bees their entire lifetime to make a teaspoon of honey, visiting 50 to 100 flowers daily flights to gather nectar. This incredible substance and the tiny insect that produces it are no accident of nature; they were created by God’s design. The psalmist wrote that if God’s people would listen to His words, “with honey from the rock I would satisfy you” (Psalms 81:16).

Non-Native Species and the Natural Balance

Non-Native Species and the Natural Balance - Burmese Python
Burmese Python

People often disturb the delicate balance of the natural world by transporting plants, animals, or insects from one region to another, either accidentally or intentionally. When non-native species have no predators to keep them in check, or they outcompete local species for food or space, the natural balance is disrupted. The consequences are often negative.

The list of known cases of destruction caused by non-native species is extensive. Researchers say that introducing outsiders has led to 60% of local bird, mammal, and reptile extinctions. Over the past decade, Florida has spent an estimated six million dollars to control Burmese pythons. These large snakes were brought into the U.S. and sold as pets. When they grew too big to handle, people released them into the Florida Everglades. Without natural enemies in America, these snakes have been preying on local wildlife, including alligators, domestic dogs, cats, and even cattle.

A single Japanese knotweed plant brought into the U.S. can grow rapidly, has no natural predators here, and can crowd out other species, damaging buildings and drainage systems. This plant has appeared in 43 states, including Alaska. Even viruses and bacteria have been introduced from other parts of the world. COVID-19 is one example, but there are lesser-known cases too. For instance, the West Nile virus came into the U.S. from Uganda.

The number of invasive non-native species is huge. It includes Asian carp, parachuting Joro spiders, kudzu, giant hornets, sea lampreys, zebra mussels, South African red weevils, red swamp crayfish, and starlings, among others.

The U.S. government spends over three billion dollars annually on managing invasive species, and more than $150 billion yearly on agricultural damages. Globally, the bill reaches $423 billion. All of this stems from humans acting as poor stewards of the natural resources God has given us.

Cowbird Mystery Solved

Cowbird Mystery Solved
Brown Headed Cowbird

Cowbirds are quite unique among birds. A female cowbird lays her eggs in another bird’s nest. The parent birds there raise the cowbird chicks as their own, even if they are smaller than the cowbird. The cowbird mystery is how the bird, raised among a different species, finds a mate.

Recent studies have offered an answer. About a month after hatching, the young cowbird leaves the foster parent’s territory. It then encounters adult cowbirds and instinctively follows them. The foster parent does not help with this process, but their behavior allows cowbirds to reproduce.

The scientific term for the cowbird’s behavior is “brood parasitism.” Although the cowbird mystery may seem like an unusual way to reproduce, it helps maintain balance in the bird world. God’s creation has many mysteries we don’t yet understand, but as we learn more, we see the wisdom behind it. This reminds us of Romans 1:20, which states that we can know there is a God through the things He has made.

Bryan Was Right About Macroevolution

Bryan Was Right About Macroevolution
William Jennings Bryan 1913

Bryan was right. Even after a century, his arguments remain unrefuted. A play that fictionalized the famous Scopes trial was first performed in 1955, and film versions were released in 1960 and 1999. Both films were well-produced with talented actors but showed a clear bias toward evolution and against William Jennings Bryan. The character representing atheist Clarence Darrow as the defense attorney was portrayed as an intelligent, kind, and caring man. Conversely, the William Jennings Bryan character was depicted as a fool, which he was not. Yesterday, we examined Bryan’s arguments against evolution based on the origin of life and genetics/morphology. Today, we look at chemistry and species.

In Bryan’s era, advocates of evolution suggested that the chemistry of life could naturally generate complex code. The complexity of living cells was not yet understood. Bryan wrote a closing argument that he was unable to present at the Scopes trial. This document, published after his death, included these words:

Bryan was right to say that chemistry cannot explain the evolution of life. Today, no scientist can demonstrate that chemistry alone accounts for the origin of new features in living things or the complexity of life.

Bryan’s fourth argument was the lack of the emergence of new species. He pointed out that animals pass on their body plans and features to future generations. According to historian and author Rick Townsend, Bryan “suggested that no evidence had been presented to validate the claim of new species arising naturally.” As Bryan stated, “…many evolutionists adhere to Darwin’s conclusions while discarding his explanations.”

Both the biblical record and the record of paleontology show that the appearance of new, unique species stopped after humans came on the scene. Furthermore, the fossil record suggests that the number of species has decreased rather than increased since the first humans appeared on Earth. After creating humans, God rested from creation until this day.

We observe microevolution within species, but not macroevolutionary changes. The scientific community cannot demonstrate how microevolution can lead to macroevolution because changes within species hit a barrier that cannot be crossed. Random mutations and natural selection are unable to produce entirely new and unique creatures.

In a 2016 meeting of the prestigious Royal Academy of London, the conference leader and evolutionary biologist Gert Muller wrote, “The real issue is that genetic evolution alone has been found insufficient for an adequate causal explanation of all forms of phenotypic complexity…” That’s a fancy way of saying that 100 years after the Scopes trial, evidence for Darwin’s “evolutionary synthesis” is still lacking. In other words, Bryan was right.

Bryan’s Arguments Against Darwin

Bryan’s Arguments Against Darwin
Scopes Trial, William Jennings Bryan on the left and Clarence Darrow on the right

Yesterday, July 21, 2025, marked the 100th anniversary of the end of the famous Scopes trial in Dayton, Tennessee. Over the past few days, the media have commemorated it, and we have written about it HERE and HERE. The play “Inherit the Wind,” loosely based on the Scopes trial, was adapted into a movie twice, with the names changed to protect the innocent, or guilty. The real name was William Jennings Bryan, and although Bryan’s arguments against Darwin were not presented in the play or movies, they have still not been answered in the 100 years since Scopes.

William Jennings Bryan was a renowned orator of his day and a devout Christian who was not convinced of the truth of naturalistic macroevolution. One of his arguments against it involved the origin of life. Evolution does not explain creation. Evolution requires creation, and Darwin merely suggested that life got started in a “warm little pond” without explaining how that might have happened. Bryan said this:

After 100 years of research, scientists are no closer to solving the mystery of the origin of life than they were in Bryan’s day.

Another area that Bryan challenged was genetics (the passing of traits through generations) and morphology (the shape and structure of living things). Bryan expressed his doubts with a watermelon illustration:

Today, we know that DNA carries the code for proteins and regulates cell functions, but science still does not understand the body plan of living things. What was once called “junk DNA” (non-coding) appears to be involved in morphology, but its mechanism of action remains unknown. Consider the similarities between the DNA of humans and fruit flies, and notice the vast differences in their body plans.

William Jennings Bryan’s arguments against Darwin have still not been answered by science. The origin of life and the secrets of genetics and morphology are still unexplained. Tomorrow, we will look at two more of Bryan’s arguments against Darwin.

Trial of the Century?

Trial of the Century? - Clarence Darrow and William Jennings Bryan at Scopes trial in 1925
Clarence Darrow and William Jennings Bryan at Scopes trial in 1925

In July 1925, what is known as the “Scopes Monkey Trial” was held in Dayton, Tennessee. Now, 100 years later, the battle over evolution continues. USA TODAY ran a 12-page special edition on July 13, 2025, giving an excellent historical exposé and claiming that what was at stake was “modern science versus religion.” The article also addresses current issues, including the representation of LGBTQ+ books in schools today. The paper claims that the so-called “trial of the century” was America’s first major culture war battle.

In an era when American education is undergoing massive change, there are many questions: Do schools have the right to ban certain books? Who should write the curriculum? Can the Bible be displayed in public schools? Should school prayer be allowed? Are vouchers the answer for school choice? Should schools be involved in sex education? Should the 10 commandments be displayed? Should schools have chaplains?  These issues are being battled in courts, school board meetings, PTA presentations, and churches.

Many churches have established their own schools, and private schools are increasingly replacing public schools in various locations. One side effect is that money and teachers are being pulled away from the public schools. How do you teach a lab course when you have no funds to purchase equipment for students to use?

The sad part of all of this is that most of the conflict is unnecessary. The “Does God Exist?” ministry is based on the simple fact that science and faith are friends, not enemies. Modern science may disagree with some denominational teachings, but it does not contradict the Bible. If you read the Bible carefully, you will see that it consistently deals with evidence. Science is knowledge, and if God is the source of knowledge, the two MUST BE SYMBIOTIC – mutually supportive of each other.

The Scopes “trial of the century” centered on the topic of evolution. It is foolish to think that change does not occur in living things. How many different breeds of dogs, cats, chickens, cattle, and corn exist today? How did they come into being? The answer is “evolution,” but this was guided evolution. This is not to be confused with naturalism, which holds that blind chance can explain all that we observe in the natural world. Evolution is simply unfolding change, and it is undeniable, as evidenced by adaptive changes within species.
