Can babies come out half human and something else?

maybe. well I heard this story from my Mother who has been a nurse since qualifying in l943. she was shown an illustration in some sort of technical manual on abnormal Biology by a DOCTOR. No Halloween or April fool joke, of a quadruped animal resembling a young horse- but maybe about the size of a dog with a humanoid head. It was said this resulted from unnatural Human-animal ( Concupiscence) or love-making. Mother was not allowed make a copy of the photo the whole thing had an eerie ( Top secret) atmosphere, it happened c.l943. I wish I had more info she knew I was interested in Freaks so told me this story.
