In this paper, the authors analyzed 2 rare haplotypes to determine that the first Indians took two different paths in colonizing North and South America. Both journeys started about 15-17,000 years ago by crossing over Beringia which was an ice sheet that connected Siberia and Alaska. The two groups are thought to have taken separate paths and as a result might not have interacted or had a common language. One group continued down the Pacific coast while the other migrated down the Rocky Mountains. Almost 20,000 years passed before Columbus arrived to find the Indian populations possessing a rich diversity of language and culture. On a personal note, I am having my DNA sequenced to determine my haplotype. Should be interesting!
