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.

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.

The Responses of Anuran Species to Varying Levels of Ultra Violet (UV-B) Radiation

Posted on Updated on

Screen Shot 2015-10-05 at 4.24.08 PMUltra Violet Radiation and Its Role in Frog Ecology and Evolution
Ultra violet radiation, especially UV-B radiation (280 – 320 nm), has been hypothesized to be one of the major contributing factors to the decline of amphibian populations worldwide (Gardner 2001, Houlahan et al. 2000, Keisecker et al. 2001). UV-B radiation has been known to cause an increase in the likelihood of premature death, as well as malformations and deformations in a large number of frog (order Anura) populations (Han et al. 2007,  Keisecker et al. 2001, Blaustein et al 2003). While the exact effects UV-B  radiation has on frog development is currently being investigated and  debated,  many conclusions can be drawn from past and current  research. UV-B radiation  by itself is a known problem, but when  combined with other factors (pH,  temperature, water depth, mold) it can  cause a synergistic and additive effect  (Bancroft et al. 2008, 2nd  reference, Gardner 2001).

There has also been a variety of research investigating the role of physiological, molecular and behavioral (Han et al. 2007, Blaustein et al. 2003) adaptations in frog populations. These adaptations are in response to the recent increase in UV-B radiation on the surface of the planet, which has been caused by the recent decrease in stratospheric ozone (Bancroft et al. 2008, Diamond et al. 2002). In some cases, the size of the population may also have an influence the effects of UV-B radiation (Houlahan et al. 2000).

Effects of UV-B Radiation on Anuran species
Exposure to UV-B radiation can cause various types of lethal or sublethal effects on amphibians (Han et al. 2007). These effects include genetic deformations, improper development, various forms of skin malformations, and premature death (Diamond et al. 2002). Due to the recent decrease in stratospheric ozone and the decrease in surface water level in frog habitats, there has been a significant increase in the amount of exposure to UV-B radiation in frog populations (Bancroft et al. 2008).
