New human ancestor shared its turf with 'Lucy'

Humans have a new ancestor. A new hominin species that likely lived at the same time as the “Lucy” species in Ethiopia is described in a study published in Nature today. The species would have lived between 3.3 and 3.5 million years ago — a timestamp that further muddles human evolution, while also lending support to the idea that numerous hominins co-existed during the middle Pliocene.

We don’t know if the Lucy species gave rise to modern humans

Up until recently, human evolution was viewed as a fairly simple tree. Sure, it had a number of branches up at the top, but its trunk was basically one straight line, researchers thought. But with the discovery of Kenyanthropus platyops in 1999, and now with this new hominin species, that idea…
