1. About 800,000 years ago, fire was controlled by early humans.

2. About four million years ago most early human species became bipedal.

3. The Homo Habilis used to live in Eastern and Southern Africa.

4. About 12,000 years ago, humans managed to control the growth and breeding of some plants and animals.

1. What's been the role of climate change in the development of humans?

The climate change was very important en the development of humans because thanks to that change the humans had to adapt so that they could live. Then that was the beginning of brain development, bipedal development and emergence of different kind of instruments.

5. Which species survived for the longest time? For how long?

The Homo Erectus was the species that survived for the longest time on our family tree, surviving more than nine times as long as our own species. Then it means that he survive between about 1,89 million and 143.000 years ago.
