The fossils of found in 2008 had a mix of traits of both man and ape that allowed it to walk upright long distances, as well as scurry up trees. Discovered in cave near Johannesburg in 2008, the fossils of a species named “Australopithecus sediba” have given researchers clues about the evolution of man and which traits in our ancestors fell by the wayside.
Standing about 1.3 meters (4 ft) tall, sediba had a narrow rib cage similar to apes but a flexible spine more similar to that of a human. Its long arms and powerful torso helped in climbing, according to the research published in the journal Science. iolo.com
Sediba’s small heel resembled a chimpanzee’s and it walked with an inward rotation of the knee and hip on slightly twisted feet with a flat-footed gait that would have helped it cover ground, the researchers said.
“It is the perfect compromise of something that has the need to walk on the ground efficiently for long distances. At the same time, it is a very capable climber,” said Lee Berger, project leader at the Wits Evolutionary Studies Institute in South Africa.
