"It has often and confidently been asserted, that man's origin can never be known: but ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science." -Charles Darwin, The Descent of Man, (1871)
The Descent of Man, and Selection in Relation to Sex (1894 edition) with original illustrations by T.W. Wood reveals Charles Darwin's theories of human evolution with particular focus on the argument that sexual competition is the means for natural selection rather than an animal's physical and biological environment. Originally published in 1871, the book was an instant success. It remains a foundation for present-day research as an in-depth exploration noting the differences between the sexes. This book is a must-read for those interested in biology and Darwin's theories of evolution.
