It used to be a much simpler human history in my school days. Now, they tell me that evolution wasn’t as linear as we were taught.
Humans and Neanderthals and other hominids all roamed the earth at the same time.
Our earliest direct relatives emerged from Africa some 50 thousand years ago.
Others of the 15 to 20 types of early humans continued to co-exist with them.
So I am thinking, it’s kind of akin to cats. Look at how diverse they are. Look at how many different species live in jungles and mountains and homes across the world.
