Scientists discover 'earliest human remains' in Ethiopia
March 5 , 2015
Researchers have found a jawbone in Ethiopia of what may have been one of the first humans.
The specimen, which is 2.8 million years old, is about 400,000 years older than what was thought to be the time when humans emerged.
The finding also indicates that the shift from tree-dwelling to walking may have come about because of climate change.
This discovery creates an exciting link between a 3.2 million-year-old human-like primate specimen that was discovered in 1974 in the same area, scientists said.
