'First human' discovered in Ethiopia
The 2.8 million-year-old specimen is 400,000 years older than researchers thought that our kind first emerged. The discovery in Ethiopia suggests climate change spurred the transition from tree dweller to upright walker. |
A separate study in Science hints that a change in climate might have been a factor. An analysis of the fossilised plant and animal life in the area suggests that what had once been lush forest had become dry grassland. |
