New analysis of ancient human protein could unlock secrets of evolution

The technique - known as proteomics - could bring new insights into the past two million years of humanity's history

Tiny traces of protein lingering in the bones and teeth of ancient humans could soon transform scientists' efforts to unravel the secrets of the evolution of our species.

Researchers believe a new technique - known as proteomics - could allow them to identify the proteins from which our predecessors' bodies were constructed and bring new insights into the past 2 million years of humanity's history.
