    But anomalies continue to crop up. There may not be just one linear narrative.

    The origins of our species might need a rethink. An analysis of an ancient skull from China suggests it is eerily similar to the earliest known fossils of our species –found in Morocco, some 10,000 kilometres to the west. The skull hints that modern humans aren’t solely descended from African ancestors, as is generally thought.

    Most anthropologists believe, based on fossil evidence, that our species arose in Africa around 200,000 years ago. What’s more, genetic studies of modern humans indicate that we are all descended from a single population that left Africa within the last 120,000 years and spread around the world. This African group is the source of all modern human genes, barring a few we picked up by interbreeding with other species like Neanderthals.

    However, the Dali skull may not fit this story. Discovered in China’s Shaanxi Province in 1978, it is remarkably complete, preserving both the face and the brain case. A study published in April concluded the skull is about 260,000 years old. ...

    It's what'll happen when odd points of evidence appear all over the shop. Fossils are rare, in comparison with the number of live creatures of the type that existed, as are non-fossilised remains. It's amazing we have anything really and the more they look, the more they'll find. Every time they find a new data point, they'll have to redraw the graph, figuratively speaking.
