Humans reach North America is listed at ~16k years ago. That’s based on the Clovis First model that was still dominant then.
Now we know small populations of humans were already in the Americas when this chart begins, having traveled along the coast from around what is today Japan.
Archaeology is progressing so quickly these days that even XKCD is no longer an up-to-date source!
What should I search for if I want to read up more on this? I hadn’t heard of these recent developments.
“Kelp Highway” is a common name for the theory, since it involves exploiting rich marine ecosystems while expanding down the coast relatively quickly.
“Pre Clovis Sites” should get you to the level of specific digs.
“Western stemmed points” are the most solid link back to the cultures in East Asia after the last glacial maximum. I believe the genetic data is not as clear on this yet but is coming together.
The Oregon Archaeological Society’s YouTube channel has a number of professional lectures for amateur enthusiasts that touch on this - https://youtu.be/KPpgn-NVeLI?si=SCKpePUNp3pKyPSa i think this is the one with a lot of info on the evidence for links to cultures in Japan.
Reminds me of a scientist discussing an economics paper that said warming to +4°C would only cost 1% of GDP, so we should stop with all the warming alarmism.
The scientist remarked that if you entered -4°C in that calculation used in the paper you would also get 1% of GDP, but in reality -4°C would cover most of the major cities with a mile of ICE.
Because think of the the FREE ICE! The ice economy would boom! Think of all the new ice jobs!
Earth has been iceless before of course, and I’ve heard people claim its not a problem for it to happen again.
But if only this heating had occured slowly over a period of ~45 million years, nobody would have panicked. We’d adapt. Fauna and flora would adapt. We’d not even notice the ice caps melting.
Holy fuck Lemmy needs a fuckin thumbnail system for shit like this.
I assume you use a card view instead of list view. In list view every picture is shown as thumbnail. Even if there were no pictures this long you have to scroll way more in card view than in list view.
This image never fails to depress. I wonder what an updated version would look like?
