But the timing makes Homo sapiens more likely. Somewhere between thirty thousand and fifty thousand years ago, human culture exploded. We went from using the same, relatively simple tools to a cultural revolution, not only advancing our tools, but massively increasing the amount of art we made, burial rituals, obvious jewelry…Symbolism was suddenly everywhere. Before this revolution, there was lots of the same for a very long time. After, there was Humanity everywhere you looked.
