PAUL-
And hath made of one blood all nations of men for to dwell on all the face of the earth...
Acts 17:26
DARWIN-
Here is a quote from The Descent of Man:
“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
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 a baboon, instead of as now between the negro or Australian
[i.e. Aboriginal] and the gorilla.”
