Answer 1

1) True - Both of them are classified under homo erectus.

Peking man - 750,000 years ago. and Java man - at about 400,000 years ago.

2) False - Humans are not evolved from chimpanzees although Humans do shared common ancestor with chimpanzees around 7 million years ago.

3) False - Homo erectus do lived in africa but they also migrated to other parts such as western asia and then eastern asia. the firt fossil was found in Asia.

4) True - Hominins are the part of the larger primate group known as hominids. The evolution of this species took place in Africa at the end of the time period Miocene.

5) True - while the First homo species was appearing, the Africa was turning into grasslands because the climate was dring out. This change lead to stoppage in climbing the trees and moved us toward walking upright.
