Diet of early human relative Australopithecus shows surprises, says Texas A&M researcher
Date:6/27/2012

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.

Darryl de Ruiter, associate professor in the Department of Anthropology, says the new findings are in contrast to previously documented diets of other hominin species and suggests that Australopithecus sediba had a different living environment than other hominins in the region. Previous research had shown that the australopiths of South Africa lived in the vicinity of grassy and open savannah-like areas, though it was unclear whether they actually occupied a savannah habitat, or if they lived in forested margins near the grasslands.

The team examined teeth from skeletal remains of a group of newly discovered hominins found several years ago in a South African cave about 30 miles northwest of Johannesburg and dated to about 1.98 million years old. The team, comprised of researchers from the United States, Africa, Europe and Australia, named the new species Australopithecus sediba and demonstrated that it displayed a mosaic of both human-like and ape-like characteristics shared both with other forms of Australopithecus and with modern-day humans.

"By examining material recovered from their teeth using diverse tools ranging from dental picks and laser ablation devices, we were able to determine precisely what they were eating," de Ruiter explains.

"This gives us a very clear picture of their diet, and it was surprising. It shows that they ate more fruits and leaves than any other hominin fossil ever examined, more like what a chimp might eat. There was no evidence of them eating native grasses of the area at that time, wh
