2 Million Year Old Skeleton Had Mix of Ape & Human Traits

April 13, 2013 |By Reuters

Fossils of a species named, "Australopithecus sediba," show that the ancestor of man could hike vast distances and scurry up trees.

JOHANNESBURG — A 2 million-year-old ancestor of man had a mixture of ape and human-like features that allowed it to hike vast distances on two legs with as much ease as it could scurry up trees, according to research published on Friday.

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 4 feet 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.

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.

The researchers plan further studies to see how these fossils of early human relatives known as hominin compare to other remains, to help put together the pieces of evolution.

"We have more complete specimens of fossils than for any other early hominin species that has ever been discovered. What this means is that we can make assessments of the anatomy and behavior of this species with a great deal of confidence," Berger told Reuters.

Thank you so much, gata!

I think the third skeleton in your first picture is, "Nosferatu!"

Cool stuff! Thanks again, as always

Interesting variety of ribcages and pelvises! Wow!
