An approximately 8,400-year-old skeleton, discovered in Washington State in 1996, quickly gained renown for having a skull more reminiscent of Europeans than of Native Americans or their presumed northeastern Asian ancestors. Like a number of other ancient human finds in North and South America, the individual dubbed Kennewick Man didn't look like a New World pioneer was supposed to look.
New studies, however, support the traditional view that early settlers of the Americas--including Kennewick Man--hailed from Asia, not Europe. The sites of origin and the number and timing of their migrations remain controversial.
