What's been the role of climate change in the development of humans?
The role of climate change on human development is very important, because it allowed the survival of humans. The effect that caused this climate change was the vegetation in different places, it increased. That's why humans could survive in all kinds of habitats.
In your opinion, what is the most significant milestone for the human evolution? Why?
I think that the most significant milestone was the fire control. With fire, early human's diet changed, because they started cooking different things.
