Australopithecus sediba, believed to be an early relative of modern-day humans, enjoyed a diet of leaves, fruits, nuts, and bark, which meant they probably lived in a more wooded environment than is generally thought, a surprising find published in the current issue of Nature magazine by an international team of researchers that includes a Texas A&M University anthropologist.1The goofy thing is that these hominins (or at least the ones we have) ate much more of these kinds of items than any other hominin we have discovered. In fact, their diet is much more like that of a chimpanzee than a hominin. This probably means nothing more than that is what they had access to but it does mean they were having a diet different from the robusts. Au. sediba’s teeth are gracile, in comparison to those of the robusts or earlier australopiths. It was definitely a forested environment.
