Darwinism makes it possible.
Reject the Darwinian point of view, and you must reject anthropology also.

What, then, is Darwinism?
Not a cut-and-dried doctrine.

Not a dogma.

Darwinism is a working hypothesis.

You suppose something to be true, and work away to see whether, in the light of that supposed truth, certain facts fit together better than they do on any other supposition.
