This Archaeological Discovery in Oregon Could Change Human Origins

In the high desert of eastern Oregon, beneath a low shelf of rock, a scientist held a small orange stone. Clinging to its edge was the dried residue of bison blood. Nearby lay the teeth of a camel that vanished from this land long ago. When the dates came back, they did not match the textbooks. Someone had knelt in this shelter far earlier than anyone was prepared to believe. The story of who that someone was begins here.
