New analysis of ancient human protein could unlock the secrets of evolution. Bill this article by

Robin McKee, science editor for The Guardian begins by saying, 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. End of quote there. I guess one thing it reveals is that

ancient people didn't floss. Well, actually you discuss proteomics in the quest of the historical

atom, so you're familiar with this research. Yes, in the quest of the historical atom, I looked at

the new science of protein proteomics at its application to fossilized human beings and what these

protein analyses, particularly of the teethy mammal on these skeletal remains, can tell us about the

relationships of these prehistoric humans. The article says, researchers believe a technique known

as proteomics newly applied in the field of human fossils 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. Analysis of these microscopic remnants could then help to solve major

evolutionary mysteries such as the identity of the common ancestors of homo sapiens and the

neanderthals. What are your thoughts on common ancestry these days, Bill? The phrase common

ancestry is ambiguous, Kevin. It depends on what biological category you're applying it to. For

example, if we want to talk about the common ancestry of human beings, we would be looking at the

common ancestry of neanderthals, denesovans, and homo sapiens. This is not committed to there being

a common ancestor of chimpanzees and human beings, for example, or chimpanzees gorillas and human

beings. So what we're interested in here is simply the relationships among these fossil remains

of people who have been classified as belonging to the species homo. Yeah, it's kind of used as a
