5‘25“ -Scientists found the fossils of genus of human between 2million to 4million years ago. They found male and female fossils. -Then the scientists identify the brain, hands and feet of these fossils. They found a smaller brain and indicated that this might be caused by the longer walking period and less on-tree period. Also, the hands show that the genus can climb the tree. -but since the research is complicated, the scientists also questioned that these fossils cannot provide enough evidence for human's earlier genus, so such research needs further study. |
