Darwin s successor to his landmark On the Origin of Species, The Descent of Man is notable for applying the naturalist s thoughts on evolution and natural selection to human beings and speculating on our origins. Detailing his theories of sexual selection, evolutionary psychology, and evolutionary ethics, Darwin touches upon a variety of intriguing subjects, including ruminations on race, gender, and civilization. A stimulating read on the evolution of humanity s most distinguished traits and faculties, The Descent of Man remains one of the most influential and controversial scientific treatises ever composed.
