Partial skeleton suggests ancient roots for humanlike walking

June 21, 2010

An older guy has sauntered into Lucy’s life, and some researchers believe he stands ready to recast much of what scientists know about the celebrated early hominid and her species.

Excavations in Ethiopia’s Afar region have uncovered a 3.6-million-year-old partial male skeleton of the species Australopithecus afarensis. This is the first time since the excavation of Lucy in 1974 that paleoanthropologists have turned up more than isolated pieces of an adult from the species, which lived in East Africa from about 4 million to 3 million years ago.

A nearly complete skeleton of an A. afarensis child has been retrieved from another Ethiopian site Subscribers Only

Discoverers of the skeleton, led by anthropologist Yohannes Haile-Selassie of the Cleveland Museum of Natural History, consider this a Desi Arnaz moment. As the late actor often exclaimed on his classic television show, “Lucy, you got some ’splainin’ to do!” But other researchers are not so convinced that the new fossil changes much of what they already knew about Lucy and her kind.

Stand-up guyDiscoverers of a partial, 3.6-million-year-old skeleton from Lucy's species say that it unveils a surprisingly humanlike walking ability, although not everyone agrees.

Not sure what to think of this, looks like they took the skeleton and stood it upright which would be easy to do, understand why there is so much controversy on this finding.

What Was "Lucy"? Fast Facts on an Early Human Ancestor

September 20, 2006
Perhaps the world's most famous early human ancestor, the 3.2-million-year-old ape "Lucy" was the first Australopithecus afarensis skeleton ever found, though her remains are only about 40 percent complete

Discovered in 1974 by paleontologist Donald C. Johanson in Hadar, Ethiopia, A. afarensis was for about 20 years the earliest known human ancestor species.

What did Lucy look like?

With a mixture of ape and human features—including long dangling arms but pelvic, spine, foot, and leg bones suited to walking upright—slender Lucy stood three and a half feet (107 centimeters) tall.

Recreations based on other A. afarensis skulls later found nearby reveal an apelike head with a low and heavy forehead, widely curving cheekbones, and a jutting jaw—as well as a brain about the size of a chimpanzee's.

A re-creation of the 3.2-million-year-old Australopithecus afarensis known as Lucy brings us face to face with one of humanity's earliest and best known ancestors.

Here are some facts on "our human ancestor" if that is what you believe for those who are not familiar with Lucy. The jury is still out as far as I am concerned.
