after humans migrated from asia to alaska,they did what?

Answer 1

They:

Kept walking/boating until humans were throughout the Americsa. It only took 1000 years, so some of them very likely went by water. (It takes longer to populate a whole continent than to spread down a seashore - that only takes one offspring getting pissed at the old man and paddling 30 miles down the coast each generation).

Ate a lot of large critters. Mammoths and short-faced bears and ground slothes and a bunch of other "mega-fauna" that survived the previous 26 inter-glacial periods died when the monkey boys showed up. I think it's related.

Transported their techology (such as the "Clovis" spear point) with them.

Brought their langauge throughout the Americas. Google "Athabaskan, Cherokee, Apache langauge" to see the story. Later arrivals belonged to different langauge groups (e.g. Inuit, Aleuts, etc).

Differentiated into various tribes with different customs, food sources and slowly evolving langauges. Establish small families in some settings, villages in others and empires (Aztec, Inca, Mound-builders, etc) in still others.

Caught rather a lot of nasty diseases when the Europeans showed up. Returned the favor with syphillus, but it was much less devastating to entire populations and cultures.

Won some battles. Lost more of them. Strongly related to disease. Secondarily to technology.

Set up casinos and tax-free cigarette stands (but that came much later).

Answer 2

alot of them slowly continued to settle further into the continent.
It is now believed that some either by simple boat or foot continued down to south america. There has been traces of people and civilizations in peru around the same time as alaska.

Answer 4

Answer 5
