Germs Guns and Steel by Jared Diamond.

_MG_6945-Edit.jpg “History followed different courses for different peoples because of differences among peoples’ environments, not because of biological differences among peoples themselves … Far more Native Americans and other non-European peoples were killed by Eurasian germs than by Eurasian guns and steel weapons.

Guns, Germs and Steel is a book of fundamental importance in terms of understanding the evolution of human culture.
