Yes, a lie, which was easily disproven by real science which Darwin used to put down some human beings as belonging to inferior races - which Hitler and others quickly picked up as an excuse for their foul deeds. All of which proves three things:
1. Darwin was a racist.
2. Darwin was not a scientist.
3. Darwin would use anything, no matter how unfounded, to promote his despicable theory.
Yes, a lie
I guess that's what Darwin gets for quoting a CREATIONIST, and giving credence to an anthropological doctrine devised by CREATIONISTS, and citing anthopological data collected by a CREATIONIST.
But we're supposed to ignore all that, right?, 'cause there just couldn't have been any scientific racism before Darwin. (Even though there was.)
