I guess impossible to actually know but, I was thinking how worthless human babies are they can't even walk for like a year or something and than they still can barely run and have poor motor skills for years . And I was thinking since my cat is next to me he was super agile and could murder things at like 4 months old . Now since humans have great intelligence they can protect their very young with weapons and even arm the young children (not babies ofc) with sword/bow/rifle etc... but what if we never had the brains to learn that like animals who don't use weapons would we adapt and grow long ass toe nails or blade arms or just go extinct...
