Earliest ‘Human’ Discovered in Ethiopia!
Exciting news guys! BBC News released an article Wednesday revealing the unearthing of an important jawbone for human evolution in Ethiopia.
This jawbone is claimed to be one of the very first humans. The most interesting piece of this discovery is that the jawbone has been dated at 2.8 million years, 400,000 years older than researchers have thought that humans emerged (Ghosh, 2015).
This discovery can give valuable insight into transitions in human evolution. Could climate change, a recent theory, have been a catalyst for the transition from tree-dwelling to upright walking? Could Australopithecus afarensis have evolved into the first primitive human? Which trait, or combination of traits, in early humans defines us? Is half a jawbone enough to answer these questions?
