Both the Nazis and the Communists seized upon survival of the fittest theory in order to justify their wars and genocides. Was the science as bad as the morality? the End of Darwinism reports that the history of Darwinism is full of deception, error, and politics:
A series of famous biologists have appeared to support Darwin's explanation for biological change while not actually believing in it. Even Thomas Huxley, "Darwin's bulldog," privately rejected Darwin's principles of gradual transformation and survival of the fittest. But Huxley needed the money he could make writing on a controversial topic, and he had a grudge against the church. Huxley boasted that, against the church, evolution was his "Whitworth gun," an advanced firearm of the time.
Textbooks have been infested with phony examples of natural selection. Most popular has been Darwin's explanation for the height of the giraffe. This is an absurd mistake stemming from the English scientist's ignorance of giraffes and their feeding habits. Nevertheless, it has been published for nearly 140 years--so desperate are the Darwinists for evidence.
Another textbook falsehood more than a hundred years old is the claim of gills on the human embryo.
Few biologists have the nerve to go against the science establishment by criticizing Darwinism in public. However, Lynn Margulis, the world's leading authority on microbial evolution, notes the lack of evidence and calls Darwinism a "religious sect."
Ever since Charles Darwin was alive, mathematicians have criticized his theory as nonsensical. In 1966 a big international conference pitted mathematicians against leading evolutionary biologists.
In 1980 a conference of 160 biologist decided that Darwinism does not explain major evolutionary events, but in order to thwart the creationists, the biologists organized an amazingly effective cover-up.
