A new dating technique has revised the estimated age of Little Foot from 2.2 million to 3.6 million years ago. That’s significant because it places the rare Australopithecus fossil within the same evolutionary timeframe as Lucy, a hominid from a separate species. Meaning humans may not be related to Lucy after all.
Just under two million years old, Australopithecus sediba has attracted attention ever since its 2008 discovery because of its mix of ancient and modern traits. It's been hailed as the direct ancestor of the Homo genus...but that might be impossible.
Humanity language is the result of some dramatic evolutionary changes over the last few million years, which have reshaped our old primate vocal organs into the more sophisticated organs we use today. So what did all this change sound like?
This skull belonged to Australopithecus sediba, a new hominin species recently discovered in South Africa. The two million year old fossils are some of the most complete ever discovered, and they could rewrite our evolutionary family tree.
Your teeth can reveal a lot about you - including where you grew up. They're also the part of you that's most likely to endure long after you've died. Now some ancient teeth are revealing dating habits that date back a million years.
Human babies are, relative to the size of their mothers, about twice as big as chimpanzee babies. Our evolutionary growth spurt might have forced mothers to give up living in the trees, changing human social dynamics forever.
