Neanderthals are humans... well, sort of, anyway.
I don’t think they are even close to being human. Last I heard they were a dead end and the DNA pretty much proved it.
Oh, they were human all right.
I remember a photo of a grave holding the skeletons of a young woman with a young child cradled in her arms, both lying on a bed of flower pedals.
That is definitely a sign of humans mourning the loss of someone that was loved.
Nothing more human than that.
