You might think this is avoiding the question — where did humans come from? The answer, of course, is another question. What is a human? Is it when we started walking on two legs? Fire? Tools? That was all millions of years ago. Gathering in small tribal units (still millions)? Art? A million or so. Hunting? Gathering? Funerals?
We tend to think that Genus Homo from about 3/4 – 1/2 million years ago looked pretty much like us. But like us does not mean us. Were they still having sex with Homo Neanderthalis at that time? Or the Denisovans? Or something we haven’t found yet?
Culture as we like to recognize it came into play around 250-50 thousand years ago but that just means there was a lot of it shared out there. Civilizations came in about 12-10 thousand years ago. Was that ‘human’?
Let’s take a step back. We know humans succeeded because they were persistence hunters, which is basically running down animals to death. To be a successful persistence hunter you have to have a strong sense of curiosity and time. You have to be able to assemble stories. This plus this plus this means that the deer ran through here.
What does it mean to be human?
