What questions about evolution come down to is, "Who ARE we?"
Commenting on a dispute over a supposed human ancestor, Smithsonian paleoanthropologist Richard Potts told the Wall Street Journal, "Evolution is wonderfully messy." Few would dispute it, but a multitude of conflicting speculations does not add up to progress.
