4. Modern Humans Emerged 100,000 Years Earlier Than Thought (31.5 points).
Within our genus Homo, humans are relative youngsters. Gathered evidence suggests that we sapiens emerged roughly 200,000 years ago in Africa. That pales in comparison to our sibling species erectus or habilis, who were present two million years ago and persisted much longer. But this past summer, fossils and tools dug out of the Jebel Irhoud archaeological cave site in Morocco revealed that humans may have been alive over 300,000 years ago. If joined by additional supporting evidence, this finding could rewrite our origin story.
