Darwin to Hitler? No.

Here's what Richard Hoppe said about a recent book review analyzing the connection between Darwin and Hitler:

"[W]hat reached Germany was not the English version of Origin of Species, it was a translation by German paleontologist Heinrich Georg Bronn that was a main source of German notions of Darwinian evolution, and those notions were a distortion of Darwin’s views. Bronn had a substantially different conception of evolution than Darwin, and Bronn’s translation apparently incorporated a good bit of his own conception rather than being a straight translation of Darwin. Bronn even added an extra chapter to OoS incorporate his own ideas."
