We all know that in the 7th century, scholars like Al-Jahiz mentioned evolution in his Kitab-al-Hayawan or The book of animals. He talked about natural selection. It wasn't until the 1800s when some racist white Christian amateur went "HEY! I THINK BLACK PEOPLE ARE JUST LINKS BETWEEN CAUCASIANS AND GORILLAS!"
He literally said that baboons, gorillas, Australians (the aborigines), and black people (called negroes in his text) interbred with Caucasians to give African Americans. Read it to discover!
At some future period not very distant as measured by centuries, the civilised races of man will almost certainly exterminate and replace the savage races (implying black people) throughout the world. At the same time the anthropomorphous apes...will no doubt be exterminated. The break between man and his nearest Allies will then be wider, for it will intervene between man in a more civilised state, as we may hope, even than the Caucasian, and some ape as low as the baboon, instead of as now between the Negro or Australian and the gorilla
