New discoveries from several archaeological sites in North and South America suggest that ancient people first arrived in the New World much earlier than scientists once thought.

"Coexisted" with giant sloths and mastodons? Nah, now we've just got a better idea of what caused their extinction.

[–] novibe@lemmy.ml 11 points 1 year ago (1 children)

Except no. We lived with them for over 10,000 years without them going extinct. When before we thought they went extinct right after we arrived, thus concluded we hunted them to extinction.

But if we lived with them for thousands and thousands of years, that is very unlikely.

The original people of the Americas were not ancestors of the Native Americans Alice today so they either died off or left long before 13kya

DNA evidence sorta points that direction, but it's complicated. There were likely waves of migration to North America from different groups. Most of the DNA in native people can be traced back about 13k years. The link in OP points to artifacts from 27k years ago.

However, there is some evidence of mixing with a different group.

Just as mysterious is the trace of Australasian ancestry in some ancient South Americans. Reich and others had previously seen hints of it in living people in the Brazilian Amazon. Now, Willerslev has provided more evidence: telltale DNA in one person from Lagoa Santa in Brazil, who lived 10,400 years ago. "How did it get there? We have no idea," says geneticist José Víctor Moreno-Mayar of the University of Copenhagen, first author of the Willerslev paper.

This is an area of active research where a lot of old models are being thrown out over the past few decades. The idea of a single migration from Siberia, the one most of us were taught at school, is definitely wrong. Timing of the glacier movement is too convenient, and the migration would have to have happened far too quickly. What to replace it with is still up in the air.

Thank you for providing reasonable citations and adding to the discussion, you are appreciated

Using DNA sequencing, the results showed that Luzia was genetically entirely Amerindian.

Is the article talking about this find?

Alice? Who the fuck is Alice?

[–] novibe@lemmy.ml 1 points 1 year ago (1 children)

They were at least partially the ancestors of modern native people.

[–] iopq@lemmy.world 1 points 1 year ago

No DNA evidence of that is found in modern Native Americans

The phrase "peaceful coexistence" implies the existence of a darker, "violent coexistence."

Violent coexistence is what the Greeks and Turks currently have.
