Fossils may turn 'evolution on its head'
Analysis of a near-complete skeleton of a human ancestor found in Ethiopia radically changes scientists' thinking about the appearance and behavior of our earliest forebears.

A treasure trove of 4.4-million-year-old fossils from the Ethiopian desert is dramatically overturning widely held ideas about the early evolution of humans and how they came to walk upright, even as it paints a remarkably detailed picture of early life in Africa, researchers reported today.
The centerpiece of the diverse collection of primate, animal and plant fossils is the near-complete skeleton of a human ancestor that demonstrates our earliest forebears looked nothing like a chimpanzee or other large primate, as is now commonly believed. Instead, the findings suggest that the last common ancestor of humans and primates, which existed nearly 2 million years earlier, was a primitive creature that shared few traits with modern-day members of either group.
The findings, analyzed in a large group of studies published today in the journal Science, also indicate that our ancestors began walking upright in woodlands, not on grassy savannas as prior generations of researchers had speculated.
