Australopithecus sediba hominin
: New study reveals how human ancestor walked, chewed, and moved
A team of scientists has pieced together how the hominid Australopithecus sediba (Au. sediba) walked, chewed, and moved nearly two million years ago. Their research, which appears in six papers in the latest issue of the journal Science, also shows that Au. sediba had a notable feature that differed from that of modern humans—a functionally longer and more flexible lower back.
Together, the studies offer a comprehensive depiction of some of the most complete early human ancestral remains ever discovered. Since its discovery in August 2008, the site of Malapa—located about 30 miles northwest of Johannesburg—has yielded more than 220 bones of early hominins representing more than five individuals, including the remains of babies, juveniles, and adults. The evidence published in Science is based on two individuals from the site. The fossils from the site date to 1.977 to 1.98 million years in age.
