Reply to comment by Newbielurker in TIL: Sperms were thought to move by wiggling their tails side-to-side, like eels, for 350 years. But research shows that they roll as they move forward like a spinning top. by vect77
forget about calves, it was extremely 'obvious' to see childbirth as being like planting a seed in the earth in order to bring about life.
Semen was the seed, the woman was the earth the seed grows in. It makes enough sense to believe even if it turns out to be wrong. People to this day colloquially refer to men 'planting their seed'.
