These are external links and will open in a new window. Scientists have unearthed the jawbone of what they claim is one of the very first humans.

The discovery in Ethiopia suggests climate change spurred the transition from tree dweller to upright walker. The head of the research team told BBC News that the find gives the first insight into "the most important transitions in human evolution".

Prof Brian Villmoare of the University of Nevada in Las Vegas said the discovery makes a clear link between an iconic 3. Could Lucy's kind - which belonged to the species Australopithecus afarensis - have evolved into the very first primitive humans?

But the fossil record between the time period when Lucy and her kin were alive and the emergence of Homo erectus with its relatively large brain and humanlike body proportions two million years ago is sparse. He told BBC News that he was "stunned" when he saw the fossil.

The fossil is of the left side of the lower jaw, along with five teeth.

The back molar teeth are smaller than those of other hominins living in the area and are one of the features that distinguish humans from more primitive ancestors, according to Professor William Kimbel, director of Arizona State University's Institute of Human Origins. Its mix of primitive and advanced features makes the Ledi jaw a good transitional form between Lucy and later humans.

A computer reconstruction of a skull belonging to the species Homo habiliswhich has been published in Nature journal, indicates that it may well have been the evolutionary descendant of the species announced today.

The researcher involved, Prof Fred Spoor of University College London told BBC News that, taken together, the new findings had lifted a veil on a key period in the evolution of our species. The dating of the jawbone Asexual womans remains found in ethiopia help answer one of the key questions in human evolution.
