An international team of biologists, geneticists, anthropologists and biochemists has... generated genomic and mitochondrial DNA data to test theories surrounding the migration of ancient peoples in Mexico...
Prior research, based mostly on archaeological evidence, has suggested that drought-driven migration of ancient people from Mexico's north to the south occurred many times in the years before Europeans arrived. The northern region, called Aridoamerica, was dry and mostly desert. The people living there at the time survived as hunter-gatherers. Farther south was Mesoamerica, where early people survived by farming.
Prior research has shown that there were several long-term droughts in Aridoamerica, leading people to move south. But now it appears that these conclusions were in error. Instead of relying on archaeological evidence, the team on this new effort looked at the DNA of people living there to see if they were migrating.
To learn more about the history of the people living in what is now Mexico, the researchers analyzed DNA samples going back approximately 2,300 years. In all, they were able to study 27 samples obtained from eight archaeological sites from people who lived in regions of what is now Mexico.
The researchers could see that the expected migrations had not occurred. They point out, for example, that despite droughts, sometimes decades long, people living in Sierra Gorda did not leave. The team found none of their DNA in people living farther south.
The research team was not able to explain why the northerners had not migrated south when conditions grew dry, but suggest it might have been related to cinnabar commerce. The mineral was easily found in the north, and was sacred to people in the south...

...which of course doesn't explain why anyone lived in the south in the first place, if all migration were from Alaska down to Tierra del Fuego.

- 24/7 Politics: Cable Television and the Fragmenting of America from Watergate to Fox News
Kathryn Cramer Brownell
Politics and Society in Modern America #148
Princeton University Press | Hardcover
How cable television upended American political life in the pursuit of profits and influence.
As television began to overtake the political landscape in the 1960s, network broadcast companies, bolstered by powerful lobbying interests, dominated screens across the nation. Yet over the next three decades, the expansion of a different technology, cable, changed all of this. 24/7 Politics tells the story of how the cable industry worked with political leaders to create an entirely new approach to television, one that tethered politics to profits and divided and distracted Americans by feeding their appetite for entertainment--frequently at the expense of fostering responsible citizenship.
In this timely and provocative book, Kathryn Cramer Brownell argues that cable television itself is not to blame for today's rampant polarization and scandal politics--the intentional restructuring of television as a political institution is. She describes how cable innovations--from C-SPAN coverage of congressional debates in the 1980s to MTV's foray into presidential politics in the 1990s--took on network broadcasting using market forces, giving rise to a more decentralized media world. Brownell shows how cable became an unstoppable medium for political communication that prioritized cult followings and loyalty to individual brands, fundamentally reshaped party politics, and, in the process, sowed the seeds of democratic upheaval.
24/7 Politics reveals how cable TV created new possibilities for antiestablishment voices and opened a pathway to political prominence for seemingly unlikely figures like Donald Trump by playing to narrow audiences and cultivating division instead of common ground.
Kathryn Cramer Brownell is associate professor of history at Purdue University and the author of Showbiz Politics: Hollywood in American Political Life.

The only meegrating Mexican pattern of interest is the one that currently has allowed them to take over the Southwest of the United States.
THAT pattern needs to be reversed, and calling them “The Americans” has to be seen for the insanity it is.

was dry and mostly desert. The people living there at the time survived as hunter-gatherers. Farther south was Mesoamerica, where early people survived by farming.
Puzzling..to the North were green forests and fertile valleys to the northwest. To the south was greenery and water.
Yet they stayed to pick up rocks?
Either not real smart or, more likely, the analysis is lacking.

Don’t be stupid. Mexicans are Americans. Go check a globe or an atlas and get back to me.

This is a good one. I’d like to heard Steve Lekson’s comments.

Mexicans are "Americans"? Really> And I'm the stoopid guy?
Here's the atlas you're in need of:
I know it's difficult living in Santa Cruz and not having any contact with the real world. Take a nice little drive down to SD or Yuma or Tucson. It's a long way away. In between, there's some vestige of the United States of America in between. Funny how you seem to not get that.
Foam at the mouth all ya want, thems the facts.

The first map to use the name America, in 1507, applied it to Brazil, so maybe the only real Americans are Brazilians.
The Aztecs or Mexica were immigrants from the north--their language, Nahautl, is related to a number of Indian languages of the US Southwest including Ute and Comanche. So it's no surprise that DNA evidence would confirm migration from north to south.
