Which Tribe Would I Be In?

      I would be in the Coastal tribe because you wouldn't have to walk miles like the Plataea tribe because they followed there food. They have better houses called long houses because they stay in one spot at a time unlike the Plataea that lived in ti pees. Also, the coastal tribe was better fed by the ocean because the don't have to hunt for there food and get food year round from the ocean.

Migration of Native Americans

             The three most plausible reasons that the Native Americans crossed the Bering straight is the ice bridge, land bridge, Continental shelf. The ice bridge is when the water froze and the Native Americans just walked across. The land bridge is where the ocean level dropped 300ft because the glaciers where freezing up all the water then they walked across. The Continental Shelf is basically the same thing as the land bridge except less of the water froze. Personally I believe in the land bridge Theory because it seems the most plausible to me because it would be very easy to walk across the land after it froze.
