This AP Biology laboratory activity works just fine without the controversial word "evolution" included. "Population Genetics and Inheritance" would be a better title.

The evolution of “evolution”

The word “evolution” can mean a lot of things, which in turn leads to a lot of confusion! A brief look at the etymology reveals that “evolution” was originally a Latin word for “an opening of what was rolled up,” as in the growth of a plant from a seed. Charles Darwin actually used the word only once in Origin of Species, as he preferred “descent with modification.”

Today though, “evolution” is not so easily defined. Now, evolution might refer to anything from Darwin’s idea of descent with modification, to the idea that the whole universe is a progression of interrelated phenomena. Or, it may just mean “change,” which is the way I used it to describe how the term “evolved,” or changed over the years. The many faces of the modern definition have obvious scientific, historic, and religious implications. Let’s briefly explore these implications, and see how they may or may not relate to the creationism/evolutionism battle.

Evolution and science

Evolution does indeed have a scientific component to it. For example, there are creationists who have PhD’s in evolutionary biology and actively work in this field. Some of you are probably thinking “how can a creationist be an evolutionist?!” Well, think about it. Darwin’s idea of “descent with modification” does occur, right? We are not all clones, right?

You look similar, yet also different, from your parents. You are walking proof that limited descent with modification is real. There is some obvious “phenotypic plasticity”, or more simply, built-in flexibility, that, within limits, allows organisms to adapt and change. So, a creationist can be an “evolutionist” in the sense that he/she is conducting research on mechanisms of inheritance. The problem is not that the creationist is being a heretic and rejecting the Genesis account, where God clearly says He created different kinds of organisms. The problem is the many faces of the word “evolution,” and applying the “universal progression” idea of evolution in this instance is improper.

The photo above is from my DIVE Biology curriculum. Lab activities designated “AP” are recommended by the College Board, creators of the AP exams that high schoolers can take to receive college credit for high school work. However, because of the confusion over what “evolution” means, tagging on that word alongside “population genetics” is unnecessary. If, by evolution you mean the “universal progression” idea, then it is laughable if you think this lab activity is going to prove that. The lab is actually just a card-type game that uses multiple forms of the same gene, called alleles, to show the effects of a lethal mutation on a population. It also teaches students about the inheritance mechanism known as genetic drift.  However, if by “evolution” you mean the self-evident truth that limited “descent with modification” occurs, then this lab does a pretty good job of showing how some genetic mechanisms of inheritance work. Because of confusion over the word evolution though, it would be more appropriate for the College Board to title the lab simply “Population Genetics”, or “Population Genetics and Inheritance.”

But what happens when an evolutionary biologist, who is not a creationist, finds out creationists oppose the teaching of “evolution” in schools? Well, they may end up saying pretty crazy things! For example, take evolutionary biologist Dr. Justin Bahl, who in a recent opinion article in the Houston Chronicle, claimed that creationists opposed research on pathogenic viruses!   Obviously, his confusion is over the word “evolution.” Creationists object to the naturalistic “universal progression” idea of evolution. However, I have yet to hear of a creationist who opposed research on how diseases develop resistance! Instead, a creationist who is also a scientist would use every inheritance mechanism currently known in an effort to discover disease cures.

Viruses, bacteria, etc. develop drug resistance. This is self-evident. It is also self-evident that viruses and bacteria almost never show the “universal progression” idea, which would require they create new, functional information, and lots of it. They have never displayed anything more than a limited “descent with modification.”

Rapid evolution” is another growing area of “evolution” research that interests creationists. A Google search of the phrase “rapid evolution” produced 130,000 results! So what is “rapid evolution,” and how is that different from just normal evolution? Well, the difference lies in Darwin’s idea that evolution requires millions of years of “numerous, successive, slight modifications” (Darwin’s own words in Origin of Species). But Darwin’s “gradualism” is really part of the unscientific “universal progression” idea.

Darwin said his theory would “absolutely break down” if it could be demonstrated that a complex organ formed without involving gradualism. Well, that’s exactly what happened in a transplanted population of wall lizards, who developed a “brand new structure”, without any known genetic changes! But, they are still just wall lizards, with no change of kind.

So what is “rapid evolution”? Well, it is exactly what scientists like Dr. Bahl study! “Rapid evolution” is about studying fairly significant changes in populations that occur in just a few generations. It occurs in everything from the viral pathogens Dr. Bahl researches, to plants, to trout and more. To a creationist though, “rapid evolution” is mainly just adaptation, and the more we learn about it, the more it confirms what creationists already knew, that life was designed to adapt! Also, “rapid evolution” is what creationists sometimes refer to as “microevolution.”

Evolution and history

Creationists have no objections to testable, repeatable science. So what is this creationism/evolutionism battle about then? Well, it is a battle over how to interpret history. Scientific research is about conducting experiments and verifying the results with further experimentation. Natural history research is ultimately about interpretation, not verification. It really boils down to storytelling. In fact, a common phrase geologists like to use is “every rock has a story.” Under what conditions was it formed? What is it composed of? When was it formed? Geologists and other naturalists can perform a variety of scientific tests that can then be used to help them write a story about the past. However, any story they come up with, creationist or otherwise, is still an interpretation, not a verification, of the past.

But if history is about interpretation and storytelling, while scientific endeavors are about repeatability and verification, then why is history part of a supposedly scientific course like biology? Well, history does matter, so you cannot completely exclude it. However, when a biology textbook writer inserts the unscientific “universal progression” idea of common descent from single-celled organisms, to the exculsion of ideas related to uncommon descent, then that’s a problem. In a biology textbook, the natural history component should be very minor, and should not dogmatically assert the “universal progression” idea, using descriptions like “animals arose from bacteria,” etc. One focus of any historic component in a biology course should be on using the body of past scientific research to further unlock the mysteries of the various mechanisms of inheritance.

Evolution and religion

Ironically, while confused scientists like Dr. Bahl are making false claims that creationists are “anti-science,” it is actually the evolutionists who are stifling scientific progress! A glaring example is Eugenie Scott, the soon-to-retire director of the evolutionist propaganda mill known as the National Center for Science Education (NCSE). Behaving like a villain of science, Scott recently proclaimed that the 21st Century Science of epigenetics was too hard for high school students  to learn! This is completely false. Epigenetics relates to the set of biological information that directs the genes, switching them on and off at certain times and places. Epigenetics is like the captain that directs the “ship” known as the genome. This is an analogy a 5-year old could understand! Epigenetics is also another mechanism of inheritance that is contributing to our understanding of human health-related topics like those Dr. Bahl studies.

But why would an organization like NCSE, whose purpose is supposedly to defend the teaching of evolution, be opposed to teaching evolution? Once again, it depends on what you mean by “evolution”. The evolution NCSE is defending is the “universal progression”, naturalistic form, and they make this abundantly clear. As dogmatic Darwinists, they presuppose a simple cell filled with one-dimensional (linear) DNA that randomly mutates and magically generates new information.

But 21st Century science reveals that the cell is anything but simple, and DNA actually works in 3-dimensions (4 if you include time), not one! To say a cell is “simple” is as false as saying the infrastructure running New York City is “simple.” Since dogmatic naturalistic beliefs also presuppose gradualism, they often feel a need to suppress new discoveries related to cell complexity.

And yes, naturalism is a religious belief system. As a recent lawsuit filed in a federal court states, naturalism directs one to ask “ultimate religious questions” such as “where do we come from?” Ultimate questions like this are not scientific questions, because we can’t use scientific methods to answer them. There really is no conflict between science and religion. The “battle” is about religious belief systems, like naturalism and Christianity. And it is a battle, not a war, because the war has been won through Christ!

While secular humanists and atheists almost always have naturalism and its related components like evolutionism as core tenets of their religion, many other religious people view God as using evolutionism to bring about life. So, it is not just atheist/humanist folks who incorporate the “universal progression” form of evolution into their religious beliefs. Many theists do as well, which is why it is right to say that it is a violation of the 1st and 14th amendments when a public school uses naturalism in an effort to address origins questions.

Should scientists drop the word “evolution?”

Journalists, who are typically not scientists, are almost always confused about evolution, to the point that some even think Texas has banned the teaching of evolution! Of course, that is as false as Dr. Bahl’s claims that creationists are against the study of diseases. But, because so many are so confused about evolution, mainly because it can mean so many different things, wouldn’t it be better to just stop using the word in scientific circles? Instead of “evolutionary biology”, we could have “hereditary biology.” This wouldn’t change Dr. Bahl’s job a bit, as he would still be studying how pathogens use different mechanisms of inheritance to develop drug resistance. And instead of studying “rapid evolution”, scientists could study “adaptation” instead, as this is mainly what is happening. Environmental conditions change, and organisms adapt.

So yes, scientists should drop the word “evolution,” and put the “universal progress” form of it in a philosophy, history, or religion class. In America, the time is past due to take the religious, “universal progress” form of evolution out of the public school science classroom where legally, it doesn’t belong.
