A Christian Response to Ray Comfort’s ‘Evolution vs God’

Posted on

Tyler Dalton McNabb and I co-authored this back when Comfort’s ‘Evolution v God’ video came out and I wanted to repost it here because… well, because I like what we’ve written on the topic.

Ray Comfort has recently released another youtube sensation with his movie Evolution v. God. In typical Comfort fashion, Comfort interviews a handful of relevant college professors and students on the topic of evolution. Comfort’s main assumption in this movie seems to be that one must choose between God and evolution. In this battle royal or winner takes all match, Comfort argues that since evolution is bad science (if science at all), and the existence of God is obvious, God wins!

Screen Shot 2014-12-11 at 8.24.26 PMIn order to get to this conclusion, Comfort asks particular questions that range from basic epistemological questions to basic biological questions. It is in virtue of this that we will be separating this response into two major sections. The first major section will focus on the philosophical material that this movie contains, while the second major section will deal with the scientific material that this movie contains. In the following respective sections, we will be arguing that Comfort’s movie is based on both bad philosophy and bad science. Though in the end we will not be able to recommend this movie, we would like to recommend alternative apologetic resources at the end of this review.

Now before we begin this response, we would like to take time and mention that this response is in no way an attack on Comfort as a human being. We believe Comfort to be a loving Christian who has been mightily used by God. Though we are sure that many people will be in heaven because of Comfort and his ministry, we do feel that Comfort’s reasoning in this video reflects both poor philosophy and poor science. It is in virtue of this that we feel that Comfort’s video helps create an unnecessary stumbling block to the Gospel.

Alright! Go ahead and watch it.

Why You Should Genetically Engineer Your Children

Posted on Updated on

Screen Shot 2015-10-09 at 8.45.55 PMMost of us would do anything to help our children have the best future possible. We would make sure they had the best prenatal environment, the best diet and be sent to the best schools, all so that they could have the best possible future opportunities. But what would we do if we could, before they were born, alter our child’s genes in order to guarantee that advantage? The choice of genetically engineering our children is rapidly becoming a scientific reality, and we are faced with the question: If we are able to safely engineer a child at the genetic level… should we?

Genetic engineering is a topic that is greeted with a combination of curiosity, skepticism and apprehension. Those in favor of genetic engineering have been accused of “playing God”, whereas those opposed have been characterized as being against scientific progress. Many people view genetic engineering as something confined to the domain of science fiction; something so far in the future that it needn’t be worried about. However, with the advance of modern technology, this attitude towards genetic engineering is not only misguided, but can be dangerous.

Cancer – What is it Anyway?

Posted on Updated on

Screen Shot 2015-11-01 at 3.51.13 PMMany of you have likely encountered a kind of hype that is based almost entirely on the ignorance of the readers. People get a small glimpse into something they [rightfully] see as important, but because they don’t really understand it… they end up drawing erroneous conclusions.

Lets face it: many people don’t really understand cancer.
Its a difficult disease to understand, and people will often assume that there is some easy cure ‘out there’ and it is being concealed/ignored because cancer research facilities are just in it for the money (or… you know… something like that).

The first step in correcting this misconception is to understand what cancer is. With a proper understanding of the complexities of cancer, we can (hopefully) communicate this with people who do not understand it.

Cancer – What is it Anyway?

Cancer is the name given to a large group of diseases  that behave in a variety of different ways, depending  on the type of cell from which they originate. Broadly  speaking, cancer is associated with at least two  primary symptoms: uncontrolled cell division and  metastasis. In normal cells, the cell cycle is a tightly  regulated system that is highly controlled and  managed by proteins, enzymes and the corresponding  genes on the DNA molecule. In some cells, however, the regulations of normal cell processes are interrupted/altered by mutations. These mutations cause many genes to be expressed inappropriately, and this can lead to cancer.

Newly Discovered Functions of Pseudogenes

Posted on Updated on


Researchers have noted that there are portions of the DNA that look similar to functional genes, but contain lesions or premature stop codons. These genes have been assumed to be largely non-functional, but recent research suggests that many of these ‘pseudogenes’ are actually functional.  This paper is an overview of some of the research done in the area of  pseudogene functionality. I address several recent advances in the  area of genetic research regarding pseudogene functionality  chronologically, starting from one of the first discoveries of a  functional pseudogene and ending with a paper from this year (2013). Broadly speaking, it would seem that the assumption of non-functionality has been overturned regarding many pseudogenes, and the evidence suggests that many more pseudogenes may have a function that has yet to be discovered.

Screen Shot 2015-10-27 at 9.22.09 PMPseudogenes have been typically understood as portions of DNA  that have lost their function and remain in the DNA as a relic that  signifies past functionality. The prefix ‘pseudo-‘ indicates that  something is fake or false, and a pseudogene is a portion of DNA  that looks like a functioning gene, but is not actually functional. Pseudogenes have been placed in the ‘junk DNA’ category, ‘dead’, non-functional by-products of evolution. If a pseudogene is transcribed at all, it is often considered to be largely a neutral process that hasn’t been weeded out by selection. However, recent evidence has shown that many pseudogenes have very important functions in the genome of nearly every organism, humans included. There are very good reasons to revise the definition of ‘pseudogene’ to include a wide variety of biological functions, from gene expression and cellular function to gene regulation and tumor suppression. The newly discovered functions are making the term ‘pseudogene’ notoriously ambiguous. This review will analyze a small handful of functions discovered for pseudogenes that were previously assumed to be non-functional byproducts of genome evolution. It is not intended to be an exhaustive treatment of newly discovered pseudogene functionality. Functions are being ascribed to pseudogenes on a fairly regular basis in contemporary genetics literature, and some of the literature is reviewed in chronological order.

Darwin’s Postulates & Firemouth Cichlids

Posted on

This was a research project done in Evolutionary Biology (BIO405W) during the spring 2013 semester at Buff. State


Cichlid fish are one of the most biologically diverse groups of vertebrates on the planet. This diversity (as well as population size, reproduction rate, etc) allows scientists to study the cichlid evolution, and the role of natural selection, more closely than other populations. Many aspects of cichlid characteristics have undergone (and are currently undergoing) selective pressures. Cichlid evolution can be found at multiple levels, including behavioral changes, molecular adaptations, size and coloration variation.

Screen Shot 2014-07-24 at 10.42.50 AMThorichthys meeki is a species of cichlid commonly known as the “firemouth”, because of its bright red-orange coloration on the jaw. This specific coloration is unique to the firemouth, and is used in mating, competition and defense, and is therefore strongly affected by selective  pressures. In general, male firemouth cichlids have prominent  jawline coloration (10). The female Firemouth cichlids have specific molecular adaptations that that allow them to see the male coloration very clearly (6).

In the case of the firemouth cichlids, jawline coloration in males (and the subsequent female response) plays an important role in the evolution of the species due to the pressures of sexual selection. Sexual selection has been shown to be a mechanism of significant biological change for firemouth cichlids, even if the environment stays very stable (9), and research confirms that male coloration corresponds to sexual selection by the females (8). The females tend to mate with the more dominant males, so any characteristic that improves one’s chance of winning in a male-male competition scenario will be selected for. In any cichlid population, males who display the same color will compete more intensely. In firemouth cichlid populations, all of the males have a distinguishing red color, so male-male competition is very strong (4).

firemouthIt has been shown that smaller, less dominant males have physiological and behavioral changes during any social interaction with a more dominant cichlid. (3).  Many times, cichlids will engage in “pre-fight behaviors” (7) and  whichever male is smaller and duller will back down (5).    The coloration allows the more dominant males to emerge victorious from a fight with other males, without even having to engage in actual physical contact. The firemouth cichlids open their mouths and expose more of the red jawline. This behavior enlarges the head considerably when seen from the front and the side. In the event that there is no definitive pre-fight winner, they will engage in the more dangerous physical form of fighting. (1) In many cases, coloration is directly correlated to body size, which also plays a role in determining the winner of the conflict. (2) Read the rest of this entry »

Homo sapiens, Neanderthals & Denisovans; Did They Interbreed?

Posted on Updated on

Screen Shot 2015-10-27 at 9.40.20 PMRecent discoveries in DNA have shed light on the relationship of Homo sapiens and extinct hominids, Homo neanderthalensis and Denisova hominins. There is evidence to suggest that all three lived around the same time, and possibly in the same area (Krause et al., 2010)(Meyer et al., 2012). If these three groups lived close together, it should be possible to detect whether or not theyinterbred. If H. sapiens interbred with H. neanderthalensis and D. hominins, we should be able to find genetic evidence of this interbreeding in modern H. sapiens genomes. Using modern genetic examination (Gibbons, 2010), scientists have determined that H. sapiens did interbreed with both H. neanderthalensis (Green et al, 2010)(Hawks, 2013)(Meyer et al, 2012) and with D. hominins (Hawks, 2013)(Meyer et al, 2012).

Homo neanderthalensis fossils were first discovered in 1856 in Germany, and ever since, scientists have been exploring the relationship of Neanderthals to modern humans. (Gibbons, 2012) The first “draft sequence of the Neanderthal genome” was published in 2010 (Green, et al), and that has given us insight into the relationship of Neanderthal DNA to the DNA of modern humans. Using data obtained by the Human Genome Project (Intl Human Genome Sequencing Consortium, 2001), scientists can compare human and Neanderthal DNA in order to discover the genetic relationship between the two.  The evidence suggests that Neanderthals lived in both Europe and Asia before going extinct around 30,000 years ago (Green et al, 2010). However, many of the Neanderthals interbred with H. sapiens before going extinct. According to Green and colleagues (2010) andHawks (2013), modern humans living outside of Africa represent between 1% and 4% of ancestry from Neanderthal populations. It is possible, with modern genomic technology, for the average person to send a sample of her own DNA to a lab (ex: ‘23andMe’) and get results showing her ancestry. If she has European ancestry, it is possible that she will also have some small percentage of Neanderthal ancestry (Gibbons, 2012). These sorts of results would only be possible had the Neanderthals interbred with direct ancestors of modern humans. Not all of the evidence suggests that Neanderthals interbred with the ancestors of modern humans, however. A study showed that there were no contributions from Neanderthal mtDNA to modern human mtDNA from a specimen recovered from Mezmaiskaya Cave in the northern Caucasus. (Ovchinnikov, 2000) This is not necessarily contradictory data from the other studies; it shows that not all Neanderthal populations interbred with modern human populations.

Rethinking Aristotle: The Unwarranted Rejection of ‘Final Causation’ in Modern Evolutionary Biology

Posted on Updated on

Screen Shot 2015-10-27 at 9.49.16 PMWhy is the polar bear’s fur white? Why does the snake have the ability to unhinge its jaw? At first consideration, the answers to these questions are fairly straightforward. A polar bear has white fur for camouflage and the snake can unhinge its jaws to eat large prey. However, behind these questions lies a larger question, a question that is not directly answerable by describing the function of a certain feature. This question is of final causation, purpose or teleology. Does the polar bear have white fur because camouflage was the purpose of white fur? Is the snake’s unique unhinging jaw a result of a purposed process, with eating as a goal? Or are these features just the accidental by-products of the purposeless mechanism of evolution? Aristotle was under the impression that you do not fully understand an object unless you understand all of its explanations, including teleology, which Aristotle referred to as ‘the final cause’. Is that standard of explanation accepted today? And if we don’t embrace a teleological explanation today, is that rejection justified?

“Aristotle was one of the greatest philosophers and scientists the world has ever seen”. (Dunn, 2005) He was one of the first people to propose a formal logical system, a functioning ethical system, a methodology concerning causality and a systematic way of studying the natural world. During his study of the natural world, he spent a large portion of his time studying life; a field that we now know of as biology. “Aristotle’s studies encompassed the entire world of living things. Many of his descriptions and classifications remain sound today” (Dunn, 2005)

In addition to his study and classification of organisms in the natural world, Aristotle had a very specific way of looking at natural and man-made objects. In Metaphysics, Aristotle explains the 4 different types of aition, often translated as ‘explanations’ or causes’. He believed that in order to fully understand something, you have to understand it in light of the four causes. If you didn’t understand all four of the causes, you didn’t actually understand the object in question.
