Fire (7 jun 1000000 año aC – 7 jun 40000 año aC)

Descripción:

As with much of early civilization, our knowledge of when people first did what is limited by what we can find evidence for. So for instance, we think that humans first learned to control fire between 400,000 and 1 million years ago. That's a pretty wide range, and it might have been much earlier. But we don't know for sure.
