Scientists have obtained a fascinating new insight into the evolution of humans and our ability to walk. It comes from the fossilized bones of a foot that were discovered in Ethiopia and dated 3.4 million years old.
The researchers say they don't have enough remains to identify the species of hominin, or human ancestor, from which the right foot came. But they tell "Nature" journal that the shape of the bones shows the creature could walk upright at times.
