pre-colonial americas settled in at least three waves

16Jul12

Americans have been showing their independent streak for thousand of years. Samples of fossilized faeces from caves in Oregon show that two distinct tool-making cultures lived side by side more than 13,000 years ago. And a genetic analysis of living Native Americans from dozens of cultures indicates that, in prehistory, North and South America were settled by at least three waves of migrants from Asia.

Together, the studies — published this week in Science and Nature — support the idea that humans settled the continents along the Pacific coastline first, fast and furiously, and moved inland later.
