DNA reveals details of the peopling of the Americas
Science News ^ | August 12, 2013 | Tina Hesman Saey

The scientists examined the DNA of mitochondria, tiny power plants within cells that get passed down from mother to child. Scientists use mitochondrial DNA from living populations to decipher ancient movements of their ancestors. Most studies have examined only a small part of the mitochondria's circular piece of DNA. But Antonio Torroni, a geneticist at the University of Pavia in Italy, and his coauthors compiled complete mitochondrial genomes from 41 native North Americans and combined that data with information from previous studies... supports the widely accepted notion of an initial coastal migration wave. A second wave of migration probably left Siberia only a couple thousand years after the first wave. Instead of trickling down the coast, the second group slipped through an ice-free corridor running from Alaska into what is now southern Canada, the team found. The second wave never made it south of the present-day United States.

The mixture of first-wave and second-wave genetic signatures in some Native Americans today indicates that the newcomers and existing populations interbred.

A third wave of migration started around 4,000 years ago in Alaska and swept mostly eastward across Canada.

Previous studies of human migration into the Americas have sometimes focused on two types of languages that emerged among the tribes: the Na-Dene language family, including Navajo, Apache and Tlingit, and non-Na-Dene languages, including Algonquin, Ojibwe and Chippewa. Scientists had thought the language groups reflected genetic separation, with the second wave being restricted to the Na-Dene language family. But Torroni and his colleagues discovered that second-wave genetic marks occurred in people who spoke languages from both groups.

There are no humans native to the Americas...everybody migrated here.

Technically speaking, everyone outside of Africa is a migrant. Some people just happened to migrate before other people.

"We are all immigrants."

Actually (as was pointed out to me decades ago by a Brit) we're all just bloody visitors to the planet anyway.

"Personally, I like "NDN". "

Careful. There's a line out there drawn between Big-endians and Small-endians.

The video does not support “European.”

[sarcasm]The original peoples of the Americas were Spanish-speaking Roman Catholics who were socialist, pacifist, vegetarian, and environmentally concerned. They have always lived here. They never migrated from anywhere. They spring from the very Sacred Soil of their Socialist Motherland and had no depravity, original sin, or evil inclination of any kind. These latter concepts were invented by white Europeans to justify their e--vil, non-melanin-enriched natures.

This is the Truth. Any "science" that says otherwise is an alien ideology imported by the Foreign Devils. The USA is a lousy country. It is the lousiest country on the face of the earth and is responsible for Columbus and for all the sufferings of all the peoples of Central and South America throughout history (Spain, the apex of indigenous Hispanic civilization, is sacrosanct). The USA is so lousy, it never should have been founded in the first place.

There is only one way to undo the damage done by a country that never should have existed in the first place . . . that is to turn its government into a totalitarian state with total power over everyone within its accursed borders, including the originally aggrieved indigenous peoples. This transformation of an evil country that never should have existed into a totalitarian state will make everything all better and the oppressed pipples will be happy again.[/sarcasm]

Supporters of indigenous cultures in South and Central America have less use for Spain than they do for the US.

But don't let that stop you when you're on a mad rant.

Good heavens, what did I say that got your panties in a wad? Did you not see the [sarcasm] tags? Do you just have a policy of getting ticked off at everything I post? And it was meant to be humorous too!

If Spain is so politically incorrect, then why is Spanish (the language of a European conqueror) being shoved down our throats as the language of a sinless "indigenous pipple?" And I don't suppose you've ever heard of the old Falangist doctrine of Hispanidad (the Hispanification of the world and union of all Spanish-speaking peoples), huh? Jose Antonio Prima de Rivera may have come up with that one, but it sounds just like the "left wing" nationalism of Western Hemisphere Hispanics.

King Juan Carlos? That you???

There are centuries of bad will and resentment between South American Indians and Spain that go beyond anything they might feel against the US.

Would that get in the way of your policy of going after Catholicism time and time again because of personal disillusionment?

And it was meant to be humorous too!

One thing I learned the hard way: a trick of humor is knowing when to quit.

Believe it or not, this time I wasn't "going after" Catholicism. I was "going after" the racial mysticism of the contemporary Left that holds that evil rednecks oppress allegedly indigenous Spaniards. Besides, don't you know that "Hispanics don't count" as Catholics? It's like how Blacks are never considered Fundamentalists.

Christopher Columbus Discovering America is all Sarah Palin's Fault!

At least that is what the School books teach, because She said she could see the North Pole from her house...or something like that.
