America was connected with Asia via Alaska.

huh, well that does make sense. I still think it would have helped if they had actually tested the DNA of some of the indigenous American people though.

Pretty sure they have. 

The land bridge was pretty huge, it was basically a country, and the group of people didn't just cross it, they lived there for a period of hundreds of years I believe before moving into what we know as modern day Alaska, then Canada/America, then another group went off into Central/South America, etc. 

Another interesting random thing I find interesting: domestication of cows was kinda of a big deal for humanity since it gave us access to milk outside of just mommy's milk (lol). But apparently all cows descend from basically a group of 80 cows that were domesticed somewhere around Iran. Domesticated cows became kind of a big deal in Europe, and cheese then became a thing too because it was easier to digest.
