There was no first human…



I like it. Let’s us know we’re all related, I mean really all of us. Have fun.

The thing that defines our species is sex, i.e. nookie. If we can have viable kids, whoever it is you do it with is our species. Now that we have found Neanderthal genes hanging out in Euro populations (they had red hair), we know we are the same species as them. Could be some Physical Anthropologists are correct in their belief that we are the same species as Homo Erectus, and that everyone since that time may have been having viable offspring with a host of other variations on the human theme. A few years ago, you would have been horsewhipped for suggesting such heresy.
