Is the Woodburn longhaired man/woman/sasquatch any relation to Kennewick Man? The Clintonistas did their best to see to it that Kennewick Man would be buried away and lost to science, but I think the bones are still in someone's safekeeping.
Probably another human species. See the book, Extinct humans." The Kennewick case is still in court and DNA samples were reported as 'inconclusive.'
