I went to a school once that was able to buy the entire library of a very old school. It had many first editions of the whole panoply of evolutionary writers of the 18th century. It was a real hoot to read some of those and to see them say exactly what neo-Darwinists now claim the old-time Darwinists never said and had been falsely attributed to them by opponents of Darwinian evolution. Yes, old evolution books reveal a lot! You can get tons of them at www.archive.org. Read Osborn's crazy abiogenesis theories, Boelsche's german evolution book that influenced the Nazis, tons of stuff on eugenics, "ontogeny recapitulates phylogeny", Piltdown man, monistic philosophy, "orthogenesis", nutball theories of heredity, Haldane's defense of Lysenko, life from crystals... Haeckel's Riddle... So much good stuff! Here and here and here.
Let me say here that I wrote 18th century which should have been 1800s or 19th century, so I won't get some moron who wants to make a point without considering the most obvious solution to the problem being a typo.
And thanks for the link. I remember reading in one of these books the idea that Asians descended from the orangutan, the blacks from gorillas, and whites from the chimp. You can find an example for almost anything that modern day evolutionists claim was never taught by past evolutionists.
