Way of the Mind

Richard Dawkins has posted an open reply to a letter from a Jew deceived by Expelled, who believed the propaganda movie’s absurd claims without any fact checking. I suggest you read Dawkins’ reply in full, of course, but the subject of this post is this part in particular:

Hitler did attempt eugenic breeding of humans, and this is sometimes misrepresented as an attempt to apply Darwinian principles to humans. But this interpretation gets it historically backwards, as PZ Myers has pointed out. Darwin’s great achievement was to look at the familiar practice of domestic livestock breeding by artificial selection, and realize that the same principle might apply in NATURE, thereby explaining the evolution of the whole of life: “natural selection”, the “survival of the fittest”. Hitler didn’t apply NATURAL selection to humans. He was probably even more ignorant of natural selection than Ben Stein evidently is. Hitler tried to apply ARTIFICIAL selection to humans, and there is nothing specifically Darwinian about artificial selection. It has been familiar to farmers, gardeners, horse trainers, dog breeders, pigeon fanciers and many others for centuries, even millennia. Everybody knew about artificial selection, and Hitler was no exception. What was unique about Darwin was his idea of NATURAL selection; and Hitler’s eugenic policies had nothing to do with natural selection.

This, in retrospect, is obvious, but I hadn’t seen it explained so succinctly and clearly before. Eugenics has nothing to do with Darwinian evolution! Animal (and even plant) breeders have known about selective breeding for millennia (indeed, I think it’s even mentioned in the Christian Bible), ages before Darwin or the concept of the evolution of species. Anyone who breeds dogs, horses, birds, etc. knows perfectly well that you can cross specimens with particular characteristics to achieve desired results (say, a new hair or plumage color, or a bigger or smaller animal, or one with other specific characteristics). This can be seen as artificial selection.

Darwin’s new idea was: what if something like this also happens in nature, without intervention? And what if that is how the species in the world today have came to be? In other words: evolution, by natural selection.

Eugenics (the attempt to “perfect” the human race according to one’s beliefs or preferences) has nothing to do with natural selection. It’s simply an attempt to apply the ages old selective breeding of animals to humans.

Of course, I’m not even considering blaming animal breeders from thousands of years ago for the Holocaust. That would simply be ridiculous. But blaming something completely unrelated (Darwinian evolution) for it is even more ridiculous. Eugenics is a disgusting distortion of selective breeding (which is itself blameless for eugenics); it’s completely unrelated to evolution / natural selection.

And, when you should know better than to say such an absurdity (as some filmmakers do), it’s also a dangerous, evil lie.
