If you enjoyed that video I posted last Saturday, there's an article by Joel Achenbach that you might like to read. It's about "Ardi" (short for Ardipithecus ramidus), a 4.4 million-year-old ancestor of ours, who …
… lived more than a million years before "Lucy," a much-celebrated, 3.2 million-year-old fossil of an early human progenitor found just 45 miles away.
The analysis of her skeleton has just been completed, after fifteen years of work.
But seriously, fascinating article. Even if you didn't watch the vid.
