I find this stuff interesting:

In the journal Nature, three separate teams of geneticists survey DNA collected from cultures around the globe, many for the first time, and conclude that all non-Africans today trace their ancestry to a single population emerging from Africa between 50,000 and 80,000 years ago.

“I think all three studies are basically saying the same thing,” said Joshua M. Akey of the University of Washington, who wrote a commentary accompanying the new work. “We know there were multiple dispersals out of Africa, but we can trace our ancestry back to a single one.”

Pretty interesting that basically one group of people leaving Africa populated basically the entirity of the rest of the world. I guess in the past we assumed it was multiple waves of people. I guess the working theory was they left due to drought in Africa to seek food. Some went North (what would become Europe), some went East (what would become Asia). 

Raise a beer to your ancestors if you drink I guess, lol. They must've been tough mofos to make the journey and survive. 

Is this new? I thought this was already known?

America was connected with Asia via Alaska.

Basically Native Americans got to America via the Bering Land Bridge:

It's not a new theory but I think there was still some debate about whether or not it was multiple waves of exodus from out of Africa or centrally basically one group. 

Looks like basically it was one group. I guess they hit the equivalent of the genetic lottery because their genes have spread and spread while everyone's elses either got stuck in Africa or died out. 

Guess you can walk a lot when you don't have TV, or internet, or anything to do and just need food, lol. 

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. 

The mormons tried years back to try and prove they were descendants of Israel or whatever.

I found this quite funny as well as interesting. Not sure how true it is, but here it is.

Complete nonsense, humans were created in genetic experiments done by ancient alien cosmonauts, not sure when exactly.

At first I didn't get it and I was like "we know this already" and thought the OP article can't be true because there's been several different human species found all over up to a couple million years ago, but then realized they mean all migrations were effectively failures until the last one 80,000 years ago. I get it now.

I'll give 10 dollars to the first person who tells a KKK member that he/she's ancient relatives were african.
