Early human ancestor chewed bark

An early relative of humans chewed on bark and leaves, according to fossil evidence.

Analysis of food trapped in the teeth of the two-million-year-old "southern ape" suggests it existed on a unique diet of forest fruits and other woodland plants.

The study, in Nature, gives an insight into the evolution of what could have been a direct human ancestor.

Other early African contemporaries had a diet suggesting a grassland habitat.
