Foot fossil discovery could reshape human evolutionary history
Scientists say they have solved the mystery of the Burtele foot, a set of 3.4 million-year-old bones found in Ethiopia in 2009. The fossils, along with others unearthed more recently, have now been linked to a little-known species that was a contemporary of the celebrated Australopithecus afarensis skeleton Lucy.
The foot bones and a jawbone with teeth still attached belonged to an ancient human relative called Australopithecus deyiremeda, a more primitive species than Lucy, according to a study published November 26 in the journal Nature .
Should they hold up to further scrutiny, the findings could knock Lucy, one of the most recognizable names in human evolution, from her important spot in the family tree.
