Did you see the new report about the piece in Science? Anyone read the article and have anything to add or say?

Scientists in Ethiopia have found a 4.4 million year old human predecessor that promises to upend long-held notions of what the common ancestor of African apes and humans looked like, how it lived, and how much both lineages have evolved since diverging.

The species, called Ardipithecus ramidus, is one million years older than “Lucy,” the famous partial female skeleton of a hominid that lived 3.2 million years ago and was previously the closest scientists had come to finding the common ancestor of apes and humans. Modern genetic analysis suggests that the lineages of chimpanzees and Homo sapiens diverged more than 6 million years ago.
