Except, a stable population (not currently coping with a change from their evolved circumstances) doesn't really contain "weak" individuals beyond the normal lossage to infection, harmful mutation, violence and old age.
It may well contain groups that biologists project human cultural ideas on and call weak. But the continued presence of those groups shows them to be a useful part of the species diversity.
(I strongly recommend "The Genial Gene" and "Evolution's Rainbow", both by Joan Roughgarden, for further reading.)
PS: And yes I know there are plenty of situations where even "weak" attributes won't necessarily get weeded out, but then you'd be extending the tagline quite a bit!
