Darwin’s Mistake According to Psychologists

In 1871, Charles Darwin proposed that the difference between human and nonhuman minds was a matter of degree, not kind. A 2008 publication by Cambridge University Press calls that “Darwin’s mistake.”

Animals with very different brains, and sometimes no brain at all, can perform the essential functions needed to live and survive. God has created various animal orders with what they need to fulfill their roles in the system of life. This explains the different sizes and capabilities of brains among animals. However, the mind is something more than just the brain.

According to the team of psychologists who authored the report, only humans possess a mind capable of “the higher-order, systematic, relational capabilities of a physical symbol system.” In this peer-reviewed journal, they wrote, “We show that this symbolic-relational discontinuity pervades nearly every domain of cognition and runs much deeper than even the spectacular scaffolding provided by language or culture alone can explain.” In other words, a vast gulf exists between the human mind and the brain power of any animal.

Darwin’s mistake, according to this Cambridge University article, was suggesting that all differences between humans and nonhumans are a matter of degree, not of kind. This theory is disproved by the fact that only humans can develop abstract thinking and writing because humans alone can invent and use symbols in communication.

When God created humans in His image, He gave us a mind capable of great achievements. Unfortunately, that ability can also be used for great evil. He gave us a spiritual nature with a desire to know Him. Yet, our pride can lead us to reject God and serve only ourselves. We humans are the only creatures who can choose to fulfill God’s purpose for us or to rebel against His will. Darwin’s mistake was to think the difference between humans and nonhumans was merely a matter of degree. It is truly a difference of kind.

Taxonomic Ranking of Living Things

Suppose that billions of years ago, a once-in-an-eon event took place. In a primordial soup of chemical elements, some of them came together to form amino acids. Over time, some of these amino acids assembled themselves into complex organic molecules such as RNA or DNA. Eventually, a living cell formed, complete with a nucleus and cell walls. It became the first living cell capable of metabolizing and reproducing through cell division. This was the first species in the taxonomic ranking of living things.

Next, imagine that mutations and natural selection acted on this initial species, causing it to evolve into different species. Over eons, more species appeared until one developed sexual reproduction. Then, things started to accelerate. Billions of years of reproduction and speciation resulted in a completely different animal. This was no longer a new SPECIES but the beginning of a new GENUS. More billions of years later, a new FAMILY of living creatures emerged. As life diversified, new ORDERS of animals appeared, followed by new CLASSES. Eventually, new PHYLA emerged within the animal KINGDOM. The tree of life finally grew into the amazing diversity we have today.

The problem is that the narrative we described seems to be in reverse order. Scientific classification, or the taxonomic ranking of living things, aims to illustrate the progression of genetic change, or evolution. The taxonomic ranking follows: species, genus, family, order, class, phylum, kingdom. This bottom-up progression described in our narrative does not align with the fossil record.

The stages of life development seem reversed in the fossil record. Dr. Hugh Ross noted, “…in many instances, such as the Avalon and Cambrian explosions, enormous macroevolutionary changes occurred rapidly; later, over long time spans, mere microevolutionary changes occurred. Diversification of phyla occurred first, and in no time, while diversification of species and genera occurred over eons.”

In summary, the fossil record appears to show the opposite of what naturalistic evolution predicts. However, the pattern in the fossil record aligns with the biblical view that God created various kinds of animals, each capable of change and adaptation. Their genetic design allows for microevolutionary adaptations over time to address changing circumstances and environments.

Today, we observe microevolution happening naturally and through guided human breeding and hybridization. We see this clearly in dogs and cattle. Even though humans have bred dogs to be very diverse, they remain within the canine (Canidae) family and do not evolve into a new order. Many varieties of cattle exist, but they are still cattle. Likewise, fossil evidence of animals transforming into a different class or phylum is lacking.

The best explanation for the incredible diversity of life on this planet, whether in the animal or plant kingdom, is that it was designed by a wise Creator who endowed living things with the ability to adapt and change on a microevolutionary level. The taxonomic ranking of living things seems to occur from the general to the specific rather than from the specific to the general.

Bogong Moths and Stellar Migration

Since ancient times, humans have used the stars for navigation. So have various animals and migratory birds. Even some insects use the stars to guide their flights at night. For the first time, researchers have discovered that insects use the stars to guide their long-distance migrations. The insects are Bogong moths, native to Australia.

Researchers spent years studying the migration of Bogong moths. They wanted to know how a moth flying at night could journey 620 miles (1000 km) to a place it had never been before. After spending their summer in the cool, dark caves of the Australian Alps, every autumn, they travel to their breeding grounds in the Australian bush.

Since Bogong moths travel at night, they can’t navigate by the Sun. Past research has shown that birds, as well as some insects such as dung beetles, use Earth’s magnetic field to guide their flight. However, dung beetles travel only a few meters, not 1000 kilometers. Researchers sought to understand how Bogong moths navigate their way.

Researchers captured some Bogong moths and placed them in a planetarium-like flight simulator that blocked Earth’s magnetic field, allowing the moths to navigate by eyesight alone. The research concludes that the moths use the stars to guide them.

These moths aestivate (remain dormant) during the hot summer, huddling tightly together on cave walls or dark crevices, and migrate in the cooler weather to eat and reproduce. What is the purpose of these moths and their stellar migration? They nourish various predators in Australia. Many birds rely on them for food. Additionally, mammals, particularly pygmy possums, depend on them. Even Australian aborigines have feasted on Bogong moths.

We have described long migrations by butterflies, including monarchs and painted ladies. However, butterflies are active during the day, but moths fly at night. Bogong moths are the first insects known to migrate long distances at night using the stars for guidance. Is the remarkable migration of the Bogong moths merely an accident, or is it another essential part of an incredibly complex, designed system of life?

The Value of Fathers

Father’s Day brings to mind the value of fathers. Scientific research recently verified something that should not have been a surprise. The study involved scholars from the University of Virginia, Hampton University, and others. The conclusion was that children who have “actively involved fathers” do significantly better academically, emotionally, and behaviorally.

What is an actively engaged father? According to the study, those fathers manage parenting obligations “very well” and regularly share meals with their families at least four times a week. The study found no difference between fathers of different races. It is not the skin color that matters, but rather how actively the father is involved with his children. The educational level also did not affect the value of fathers.

What difference does marriage make? The study revealed that 51% of children with married parents had fathers who were highly engaged. That was the case in only 15% of children who had cohabiting parents.

What is the value of fathers who are actively engaged? The difference they make is in three areas: grades, behavior, and depression. Girls with fathers who are involved in their lives were 8% more likely to have better grades and only one-tenth as likely to be diagnosed with depression. In other words, a supportive father has a profound effect on a girl’s emotional well-being.

For boys, the value of fathers relates more closely to behavioral support. Boys with engaged fathers were 13% less likely to have behavioral issues in school compared to those with non-engaged fathers.

This study analyzed data on children in Virginia; however, the same findings are likely to hold true in other states and even different countries. The family is God’s design, and the greatest success in life results when a married father and mother are wholly committed to each other and work together to support their children. (See Ephesians 6:4.)

Fruit Flies and Humans

The genetic data contained in DNA is rich in information. The DNA in living cells contains molecular genes that direct the synthesis of proteins necessary for the development of an organism’s body during embryonic development . As we mentioned in a previous post, the DNA of a fruit fly is 60% similar to that of a human. How can we explain the significant difference between fruit flies and humans?

How can similarities exist in the DNA of organisms that look and function very differently? According to Stephen C. Meyer, “scientists have found that the larger informational context in which genes are expressed often determines the specific function of the proteins they produce.” For example, Meyer notes that a corresponding gene in insects and vertebrates regulates the production of appendages. However, in fruit flies, it regulates the development of compound limbs with exoskeletons and multiple joints. In sea urchins, it regulates the development of spines. In vertebrates, it regulates the development of limbs with internal bony skeletons and multiple joints.

Orthodox evolutionary theory suggests that since genes control the development of anatomical structures, the corresponding genes should produce corresponding structures in various organisms. That would eliminate the differences between fruit flies and humans. Clearly, genes perform different functions based on the larger context of information in the organism. The context contains specified information that is key to the differences.

You could compare this context variability to words in an English text. The same words used in a different context can convey a very different meaning. Words can convey their intended meaning when they are used in a systematic, organized structure composed by an intelligent mind. A hodgepodge of random words can result from non-intelligent actions, but only intelligence can create a meaningful paragraph. What does that tell us when we apply that principle to genetics? Only intelligence can create a meaningful paragraph, and only intelligence can create fruit flies and humans.

Questions About Life in Three Categories

Everyone is curious about the things we see in nature. Our posts here and on Facebook often concern animals, plants, and ecosystems. Most people looking at living creatures believe they see design and have questions about life in three categories.

The first category of questions, asked primarily by scientists or the scientifically minded, is, “How does it work?” We want to know how DNA determines the various traits of living things. We are curious about how green plants convert sunlight and carbon dioxide into energy to power their cells. How does a bat find its prey in the dark? How can an octopus control eight arms independently? The questions are numerous.

The second category is, “What is the purpose?” Atheist scientist Richard Dawkins stops after the “how” question to say, “Biology is the study of things that give the appearance of having been designed for a purpose.” But then he makes it very clear that he believes they are not designed and have no purpose. On the other hand, theologians look for a purpose. Since God created the world, He must have a purpose in mind.

Both scientists and theologians ask questions in the third category. They want to know, “How and when did this originate? How did the universe come into being? How did life come from non-living chemicals? When did the first human life originate, and how?” For believers, the Bible gives us basic answers to those questions. However, since the Bible is not a science textbook, it leaves many questions unanswered. That is where science can find answers.

Looking at questions about life in three categories, the third category is very contentious because scientists and believers disagree. I mean that unbelieving scientists disagree with believers and vice versa. But also, scientists disagree with other scientists, and believers disagree with other believers. The curious thing is that in recent years, scientists have resolved some of their disagreements. Those who once insisted that the universe was eternal have been forced to accept the evidence of a cosmic beginning about 13.8 billion years ago.

Believers, however, continue to argue about young-earth and old-earth theology. All believers need to accept the fact that the Bible does not tell us when the universe began or when Adam and Eve lived. As Christians, we must let the Bible speak where it speaks and allow science to speak where it speaks. Of the questions about life in three categories, the most important for believers to examine falls into the second category. “What is the purpose of life?” That is a question the Bible clearly answers. For example, read Romans 12:1-2, Romans 6:22, and Ephesians 3:10-12.

The Scorpion and the Mouse

Two small but fierce animals live in the Sonoran Desert of the southwestern United States and northern Mexico. One is the Arizona bark scorpion (Centruroides sculpturatus), and the other is the southern grasshopper mouse (Onychomys torridus). The scorpion and the mouse give medical science an insight into pain relief.

Arizona bark scorpions grow to barely more than three inches (8 cm) long, but their stingers pack a wallop. They are nocturnal foragers, feeding on insects, including beetles and roaches. They can live up to six years and sometimes congregate in packs. Many of them survived intact close to ground zero when the United States conducted atomic blast tests in the desert. Their venom is the most potent of any scorpion in North America, and it can be fatal to small animals, children, the elderly, or the sick.

However, Arizona bark scorpions are up against a small predator with a strong defense. The southern grasshopper mouse eats grasshoppers, centipedes, snakes, and scorpions. These mice are immune to the venom of snakes and scorpions. They also eat highly venomous centipedes, which could kill the mouse. However, this courageous mouse sneaks up and pounces on its prey like a cat.

The southern grasshopper mouse has an excellent defense against the terrible pain from the Arizona bark scorpion’s sting. If the scorpion stings humans or ordinary mice, sodium channel proteins in the skin send a painful message to the brain. However, when the southern grasshopper mouse is stung, channels block the flow of sodium, and the pain is quickly gone. More than that, researchers found that the venom injection also blocked other pain sensations for the mouse.

The scorpion and the mouse can teach a lesson to medical scientists working on pain-relieving drugs. Doctors have been trying to find ways to block human pain channels for years. The southern grasshopper mouse may have the solution if we can learn how the system works and how we can duplicate it. Science has made many medical discoveries by studying God’s design in the natural world.

Evidence for Design in Nature

On our websites, we often talk about evidence for design in nature. When average people see the amazingly organized structures in living organisms, they can’t help but feel that they must be designed. Even Richard Dawkins, the evolutionist best known for his worldwide atheism campaign, said that living systems “give the appearance of having been designed for a purpose” (The Blind Watchmaker, page 1). Of course, he adds that it is only an illusion. Atheist Francis Crick, who with James Watson, discovered the helical structure of DNA, warned biologists that they must “constantly keep in mind that what they see was not designed, but rather evolved” (What Mad Pursuit, page 138).

The intuition of design is nothing new. Plato and Aristotle saw evidence for design in nature and thought there must be a mind behind it. Of course, they could not know about the information-rich DNA molecule and the intricate structures within every living cell. They didn’t even know about cells. Even Charles Darwin thought that cells were just jelly-like protoplasm. He had no idea that there are machines, transportation vehicles, gates, duplicators, inspectors, and trash collectors within the cell wall in a city-like structure.

The more we learn about the inner workings of living things, the more we see design evidence not even imagined in previous years. Every living cell has a DNA molecule containing the instructions for building the proteins and structures required for that living creature. Computer pioneer Bill Gates wrote, “DNA is like a computer program, but far, far more advanced than any software ever created” (The Road Ahead, page 188). Even Richard Dawkins wrote, “The machine code in the genes is uncannily computer-like” (River Out of Eden, page 17).

Is there evidence for design in nature? Let me ask another question. Has any computer program ever created itself by chance, or did an intelligent mind write it? Apply that thought to the living things you see every day.

Harrier Design

The name “harrier” comes from a word that means to pillage or rob. So why are several species of hawks known as harriers? The northern harrier (Circus hudsonius) is a hawk species with a harrier design.

Northern harriers breed in Canada and the northern United States and migrate to Mexico and Central America during the winter. Their ability to “pillage or rob” comes from their long wings and tails, allowing them to fly slowly and quietly close to the ground to snatch their unsuspecting prey. They have the longest wing and tail length relative to the body size of any North American bird of prey (raptor).

Northern harriers hold their long wings in a “V” shape as they closely circle the contours of the land, ready to capture small mammals such as mice, rats, ground squirrels, and voles. Sometimes, they catch frogs or small birds. They have excellent hearing and use that to locate their prey. Farmers sometimes call these birds “good hawks” because they eliminate rodents that destroy crops and don’t bother poultry as other hawks do.

You can see the “V” shape of the wings of a harrier hawk on harrier aircraft, which were designed for short/vertical take-off and landing. A good design deserves to be imitated, and this is another example of many of God’s designs that humans have copied to create useful tools. In the harrier design, we see the work of the Master Designer.

Programmed to Survive – Self-Preservation Subroutine

HAL was Programmed to Survive with a Self-Preservation Subroutine

Every living organism is programmed to survive. That is a very broad statement, but let me tell you what I mean. On this website, we often describe the way God designed creatures with the defense mechanisms necessary to avoid, evade, or defend against predators. However, they are equipped with more than defense mechanisms. In computer terms, a self-preservation subroutine is programmed into their DNA. Even plants that have no brain or desires have this self-preservation quality. I’m sure you have seen this when you try to get rid of weeds in your lawn or garden.

Where does this self-preservation subroutine come from? Living things are programmed to survive by their Creator. In 1969, I was a college student in Cincinnati when the science fiction movie 2001: A Space Odyssey opened in movie theaters. The movie depicted space travel and “picture phone” communications. Space travel today has still not reached the level shown in the film, but today’s mobile phones make the picture phone booth of the movie seem primitive. I still don’t fully understand the movie’s meaning, but HAL, a computer with a self-preservation subroutine, fascinated me.

HAL 9000 was programmed to survive and refused to allow the human astronaut to disable him. That was the scary part of the movie for me. The concept of an evil computer or robot with artificial intelligence and a self-preservation subroutine endangering humans has become the plot of science fiction thrillers. Those human creations could become a modern Frankenstein’s monster. That terrifying scenario is what many fear AI (artificial intelligence) could lead to.

You can take some comfort in the fact that human programmers have been unable to design a computer program with a self-preservation subroutine. Look around you, and you will see a myriad of living things that are programmed to survive. God has programmed survival software into every living organism, demonstrating that He is far more intelligent than any human computer programmer. God’s wisdom and creative genius programmed all life to survive for a purpose.
