The remains of five early Homo sapiens have been unearthed at a site in northwest Africa. At around 300,000 years old, the fossils are a whopping 100,000 years older than the previous record, pushing back the origin of our species by a significant margin. And because the fossils were uncovered in Morocco -- far from the supposed origin point of our species -- the discovery is also resetting our notions of where and how modern humans evolved.
