New Texas A&M Research Confirms How Au. Sediba Moved And Ate

de Ruiter adds that the findings "show very strong support of Darwin's theory of  evolution by natural selection."

The team used a method called morphometrics that uses math and 3-D models to form a precise replica of the jawbones of species of Australopithecus and early Homo, but showing distinct differences in size and shape between them. In addition, they were able to demonstrate the growth trajectory from a juvenile to an adult form was unlike that of any other hominin species known, further supporting the unique appearance of Australopithecus sediba.

In 2012, several of these same researchers, including de Ruiter, proved that Australopithecus sediba had a forest-based diet of leaves, fruits, nuts and bark, one similar to that of a present-day chimp. The diet of early Australopithecus is a key component central to the study of human origins.          

The team's work was funded by the South African National Research Foundation, the Palaeontological Scientific Trust, the L.S.B. Leakey Foundation Baldwin Fellowship, the National Geographic Society, the Institute for Human Evolution at the University of Witwatersrand in Johannesburg, the Program to Enhance Scholarly and Creative Activities and the International Research Travel Assistance Grant of Texas A&M, and the Ray A. Rothrock '77 Fellows Program in the College of Liberal Arts at Texas A&M.
