1. Salaam was living 3.3 million years ago and the evidence of volcanic rocks which lay under or around it explained us about the existence of Salaam. 2. The climate of Africa, 6 million years ago was very cold. Also the climate was wet and tropical and there was bunch of rainforests and presence of huge lake as well. 3. The ancestors stood up because they felt the use of energy and they used to save the energy by standing up.
