So many issues. So many questions.
What was the role of dogs?
How human were we in the sense that we understand it today?
The first question was asked in the original post.
The second I ask after sitting her, with my cat sitting purring on my lap, as I stroke him.
He's old, and he stinks, because he has a bad tooth.
The reason I stroke him, rather than break his neck and eat him is because he's lovely, and I've known him for about 10-12 years, and I know him as a lovely, friendly cat that does no harm to anybody.
So I guess I'm agreeing with you, Rhiannon. If dogs were a part of human society, then humans, (which I believe we were, emotionally, intellectually, and physically, if not socially or culturally) would have formed an emotional bond with them.
