Newly discovered foot points to a new kid on the hominin block
Date:3/30/2012

It seems that "Lucy" was not the only hominin on the block in northern Africa about 3 million years ago.

A team of researchers that included Johns Hopkins University geologist Naomi Levin has announced the discovery of a partial foot skeleton with characteristics (such as an opposable big toe bone) that don't match those of Lucy, the human ancestor (or hominin) known to inhabit that region and considered by many to be the ancestor of all modern humans.

The discovery is important because it provides first-ever evidence that at least two pre-human ancestors lived between 3 million and 4 million years ago in the Afar region of Ethiopia, and that they had different ways of moving around the landscape.

"The foot belonged to a hominin species -- not yet named -- that overlaps in age with Lucy (Australopithecus afarensis). Although it was found in a neighboring project area that is relatively close to the Lucy fossil site, it does not look like an A. afarensis foot," explains Levin, an assistant professor in the Morton K. Blaustein Department of Earth and Planetary Sciences in the Krieger School of Arts and Sciences.

A paper in the March 29 issue of Nature describes this foot, which is similar in some ways to the remains of another hominin fossil, called Ardipithecus ramidus, but which has different features.

Its discovery could shed light on how our ancestors learned to walk upright, according to Levin.

"What is clear is that the foot of the Burtele hominin was able to grasp items much better than its contemporary, A. afarensis, would have been able to do, which suggests that it was adept at moving around in trees," says Levin, who was part of a team led by Yohannes Haile-Selassie of the Cleveland Museum of Natural History that also included researchers from Case Western Reserve University and the Berkeley Geochronology Center.

The finding is important, Levin says, because it shows that ther
