Evolution has nothing to do with the Holocaust.

I once heard a mainstream American preacher blame the Nazi genocide of the Jews in World War 2 on atheists and the theory of evolution. Since then, I’ve seen this view echoed in numerous Christian websites and apparently there are lectures on this topic at the Creationist Museum. This pisses me off.

It is simply illogical to blame science, evolution or atheists for this terrible chapter in history. Here’s why…

The Nazis blamed the Jews for corrupting Germany, they believed there was an international Zionist conspiracy, and the Jews were held responsible for Germany’s defeat in the First World War. Of course, there was absolutely NO EVIDENCE for any of this, and I challenge anyone to produce some.

Now, one of the dictionary definitions of faith is; ‘belief without any proof or evidence’. In this respect, the Nazi idea that Jews were evil conspirators is a belief that lacks evidence – the holocaust was an evil act of faith.

Another system of thought that promotes faith without evidence is of course religion. Yes, that’s right I’m comparing religion to the Nazis, controversial for sure, but it’s the same thing as blaming evolutionists for the holocaust!

The second point I want to raise is this: Long before Darwin was born, people had selectively bred certain animals to produce desirable results. Dogs are a prime example of this. Today we have breeds for guarding, herding and breeds that sit comfortably on the lap. Dogs that performed the best were selected for breeding and their desirable qualities passed on. Dogs that were unfit were not allowed to breed. This is unnatural selection and it has been practiced since the dawn of the agricultural revolution several thousand years ago.

So, although ancient humans lacked a theory of genetic transference, they were still acutely aware of the power of selective breeding. The Nazi Eugenics program, which sought to produce a superior master race and destroy the so-called ‘inferior’ races, could have proceeded without Darwin’s work.

It is my humble opinion that if we would all aspired to find evidence for our beliefs, then the world would be a much happier place to live in.

FACT not theory, the evidence of Evolution

It has been 202 years since the birth of Darwin, and 152 years after the publication of his epoch making ‘Origin of the Species.’ Despite being recognized as the most influential theory of modern times and being accepted almost universally by scientists the world over, much opposition remains from Christians and Creationists to the very idea of evolution. “I am not descended from a monkey,” is a commonly heard refrain from the Darwin Doubters. In this article I shall briefly examine some of the overwhelming supporting evidence that allows us to say unequivocally that evolution is fact!

1. Anatomy. Comparing the physical qualities of living creatures, for example their skeletal systems, shows that humans have remarkable similarities with other mammals (we have five digits on the end of our extremities, a spinal column, sockets in the skull for two eyes etc). From this evidence alone anatomists could construct a family tree of living species, and as it happens, humans are most similar anatomically to the apes. This suggests that these species are related to each other somehow as Darwin predicted.

2. DNA. Darwin knew that humans and apes were related, but he lived before the discovery of DNA which would later provide dramatic evidence in support of his theory. Chimp and human DNA are a 98% match. How do we know? Heat up some human DNA to around 85 degrees Celsius and the double helix breaks apart. Let things cool down and each single helix will re-bond, because, like a hand and a glove the two sides match each other.

What happens if we add some chimp and human DNA together? Well, the chimp DNA continues to seek a bond with the human DNA (all DNA has the same A,C,G, T lettering which makes bonding possible). However, because of differences in the genetic sequence the bond is not so strong. Because the bond is not as good the hybrid DNA will break apart at a slightly lesser temperature than before. Now, if you tried mixing human DNA with rabbit DNA, the bond would be significantly weaker (we are not close relations with the rabbits), and the hybrid breaks apart at a much lower temperature. Experiments like this allow us to see that we humans are indeed most closely related genetically to chimps – a result which matches the expectation from anatomy!

3. Paleontology. Preserved fossils give us a great insight into the previous history of a given species and allow us to see evolution at work. These specimens can be anatomically compared with each other and placed on a family tree. Thanks to Radiometric dating techniques we can calculate the approximate age of rocks and therefore the fossils within them. Although specimens of ancient humans and chimps are rare, they do exist, and from them we can build up a picture of how humans and apes are related. The fossil record fits snugly with Darwin’s theory, and combined with DNA evidence we can say with certainty that the common ancestors of humans and chimps lived 5.5 million years ago.

Of course, in this article I have only painted the briefest of sketches of the scientific evidence that supports the theory of evolution. I hope that the Darwin doubters will be made aware of the overwhelming supporting evidence of evolution that comes from many diverse scientific disciples:  Anatomy, animal breeding, bacteriology, biology, biochemistry, embryology, geology, genetics, taxonomy, zoology to name a few.

Actually, I feel it is a great shame that I have to write this piece on the advent of Darwin’s birthday. Despite the evidence, the creationists continue to insist on their own perverted vision of the ‘truth’ and I wouldn’t have to write this article if their views were not so prevalent. I hope that more and more people can come to understand the world, the inherent beauty of evolution, and will be able to wean themselves off their superstitious fables so that we can achieve a brighter future.

Happy birthday Darwin!
