Ok I will have to start doing long form writing soon because twitter threads aren't doing it

MULTI-REGIONALISM THREAD I will start with basic explanation of my views on the origins of modern humans, I will come back and branch out with more evidence and detail later. writing it all out in short tweets with no plan will be a challenge, give me time!

"(reinforcing OOA)" what a Muppet lmao

With so many Denisovans identified, I'm not that surprised that Xujiayao is a Denisovan; however this is a highly important paper as it refutes claims about it being a different species than the Harbin cranium, and refutes it being an early Sapiens (reinforcing OOA)

xitter.cf/Local_Origins1/status/… Even someone firmly opposed to OOA like me didn't call Xujiayao a modern human, clearly denisovan grade.

I'm back home from work and have a bit of energy to make a thread I was working on, I believe East Asia has four discrete dental groups between 500 and 80kya. Whilst largely being of the sinodont lineage they can be broken down more

Hey guys I'm at work this week so won't have time, but when I do, would you be interested in a thread about trying to make Reich's recent proposal work with dental evidence? I'm always up for a thought experiment and looking at things in good faith.

I do already have some notes on it, I think it could be possible, some elements of the model might need shifting in a way that might contradict the tool evidence or something similar.

This study challenges the result of the first study on Erectus proteins and they find that the Denisovan AMBN gene have no signal of a super-archaic origin. So Erectus as the super archaic contributor is not certain anymore. .biorxiv.org/content/10.64898…

No signal of a super-archaic origin of the Denisovan AMBN gene, a comment on the protein affinity...

Homo erectus is a species that occupies a central role in the study of human evolution. To investigate its taxonomic identity, Fu et al. 2026 extracted and sequenced enamel proteins from 6 fossils...

Someone asked why I did include the dates on this, neutral theory and coalescence was used in the study so it was probably wrong dates anyway. For example the neandersovan line is at least as old as yunxian, so at least 1.1mya, well older than the study date

In red is the Asian erectus line, with the red arrow into the green representing the superarchic contribution to denisovans. The yellow is where the neandersovans break off, they are the derived lineage relative to erectus, which eventually gives rise to blue and green

Bruh how did I miss this as the Aussie who's done autistic amounts of research into our fossils
Highly Compelling@HighlyCitedXOct 18
Study based on morphology, co-authored by C. Stringer, found that Australo-Melanesians are descended from an early migration from the Levant related to Skhul-Qafzeh peoples.

Here's the image from the Reich paper, I thought I would focus on the Eurasian side of this, obviously it is over simplified for the sake of clarity, so I have made my own.

What does the middle east have? Ergaster like kocabas? What is zuttiyeh? Other fossils like misliya are too late. I am also not sure they would dentally match a group that branches off from that neandersovan area

I am trying to be charitable but I just don't think this model aligns with the fossils unless there is a key group we are just missing in the fossil record
