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

e is much more to learn about the role of locomotion in human evolution.

"This fossil makes the story of locomotion more complex, and it shows that we have a lot more to learn about how humans transitioned from moving around in trees to moving around on the ground -- on two legs.This fossil shows that some hominins may have been capable of doing both," she says.

The fossil, dated to approximately 3.4 million years ago, was discovered in 2009 in sediments along the Burtele drainage in the Afar region of Ethiopia that is now very hot and dry. The researchers believe the area was wetter and more wooded when the Burtele hominin lived, based on its deltaic sedimentary context, results from isotopic studies and the range of fossil animals found near the site.

"We're just at the beginning of understanding the environmental context for this important fossil. It will be a critical part of understanding this hominin, its habitat and the role that the environment played in its evolution," she says.
