The Descent of Man, and Selection in Relation to Sex by Charles Darwin

4.0

The Descent of Man, the first section, advances Darwin's argument that the evolution by natural selection that he described in Origin of Species applies to man as well. It's obviously a hugely important step in understanding biology and human origins, and it does not disappoint.

The second section, on sexual selection, is probably no less important in understanding biology, but it is a lot more tedious to read. Darwin is /extremely/ thorough, especially with regard to birds.
