Sunday night Discovery channel aired two specials called "Discovering Ardi" and "Understanding Ardi." The first special focused on the findings reported this year from a 17-year project to collect fossils from the oldest known hominid skeleton in our lineage. The link between us and ardipithecus ramidus is not science fact, but the discovery of this skeleton overturns the notion that we descended from the great apes. Ardi is bipedal, not a knuckle-walker and has an opposable thumb on its hand-like feet. If anyone has not seen this special, you must. This is definitely one of the more important scientific findings in the last 20 years or so.
