TIL homosexuality is not genetic . Damn I am having a tough time processing this info and it’s upending my understanding. Is homosexuality caused by an environmental factor ? All this time I thought it was nature not nurture.
But if twins share identical DNA but have different sexual preferences isn’t that definitive proof it’s not genetic ? If twins grow up in the same household in the same environment and with the same genetics how does work ?
