newly found link between homo erectus and "Lucy"

A newly discovered Ethiopian jaw bone fragment is 2.8 million years old. It may push human evolution back another 400,000 years beyond when researchers believe humans emerged. It is a clear link between the "Lucy" (Australopithecus afarensis) remains which are 3.2 million years old, and the first homo erectus, the earliest remains of which date to 2.35 million years ago. This is a major development, but more of the skeleton or of a similar skeleton is needed to confirm. It all depends on the teeth. This must drive archaeologists nuts. I'm always amazed that bits and pieces of early human ancestors have survived at all. The climate there must help. Read more about it here http://www.bbc.com/news/science-environment-31718336
