The Historical Significance and Controversy of Coffee

Coffee is the most widely consumed mind-altering plant product in the world. The human species arose in or near the Rift Valley in East Africa, the northern edge of which abuts the forests of Ethiopia in which the coffee plants originated. The drunk monkey hypothesis proposes that human consciousness was born when our ancestors ingested fermented grapes. The stoned ape hypothesis suggests that the consciousness is due to proto humans consuming magic mushrooms.
