Sometime during the Twentieth Century, the Denobulans perfect genetic engineering. The Andorians and Vulcans make first contact with each other, and two centuries of conflict ensues. On Earth, genetic experiments begin in the 1960s that will eventually lead to the shadowy Eugenics Wars of the 1990s.
