c. 580-500 B.C. Pythagoras
Pythagoras surmised that all hereditary material came from a child's father. The mother provided only the location and nourishment for the fetus. Semen was a cocktail of hereditary information, coursing through a man's body and collecting fluids from every organ in its travels. This male fluid became the formative material of a child once a man deposited it inside a woman.
