Salon.com | News Wires: "Fossils have long provided snapshots of the human family tree, but a new find in Africa gives scientists a kind of mini home movie showing man's primal development.

Because the 4.2-million-year-old fossil is from the same human ancestral hot spot in Ethiopia as remains from seven other human-like species, scientists can now fill in the gaps for the most complete evolutionary chain so far.

'We just found the chain of evolution, the continuity through time,' said Ethiopian anthropologist Berhane Asfaw, co-author of the study being reported Thursday in the journal Nature. 'One form evolved to another. This is evidence of evolution in one place through time.'"
