Sorry for the long answer and I hope this helps!
Explanation:
The first americans migrated to north America, now known as Alaska from Siberia, Asia. These american indians migrated by foot over a land bridge known as Beringia. As soon as they arrived they had to adapt to their new environment by using all the natural resources around them. The american indians had to be very resourceful with their food, because after the earth started to warm up the glaciers started melting and the animals began to die off which left the american indians with little food, and because of this lots of the american indians homes were temporary so they could move with the animals.Then when they caught the animals, they used the animals in anyway possible using all parts. This is when the American indians started to move towards South America because that's where the animals that were left started to move for the greener grasses.
