Dedicated to paleoanthropology studies, will be releasing a multi part series on modern human origins on substack, seeking to disprove out of africa

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!

@Phillip05166897 I'll be making PCA by just eyeballing things then its interesting saldhana is older, that occipital is more modern.

English

PH78-Afram Hominin@Phillip05166897·1d

@Local_Origins1 Exactly. That globular Occipital shows up strong in comparison studies with PCA.

English

Strong Multi-Regionalism Enthusiast@Local_Origins1·1d

so the irhoud group are closely related, not a significant departure from the Tighenif group who are probably another african erectus?

Highly Compelling@CompellingDNA

Statistical analysis "reveal a close relatedness between Tighenif 2, Irhoud 11 and Dar-es-Soltane II 5 as well as between Irhoud 11 and Thomas Quarry. These results indicate morphological continuity in the Maghreb" for nearly 1 million years. nature.com/articles/s4159…

@Phillip05166897 I would describe the back 1/3 of the skull as much more globular, i had to just open 2 tabs next to each other lol at the front kabwe is more globular, similar brow profiles.

English

PH78-Afram Hominin@Phillip05166897·1d

@Local_Origins1 Try to find Saldhana and Kabwe in profile with eachother and tell me if you see a difference. It's important as it shows up in the Iwo Eleru study.

English

Strong Multi-Regionalism Enthusiast@Local_Origins1·1d

@Phillip05166897 if i was to rate how sapiens like the african specimens are LH18, 8/10, pretty good EH06, 2/10, that's an erectus lol herto, 7/10 Omo, 5/10, inconclusive for me Florisbad, 4/10 heidelbergensis jebel, 5/10 kabwe, 4/10 heidelbergensis gawis, 3/10 probably erectus ndutu, 4/10

English

Strong Multi-Regionalism Enthusiast@Local_Origins1·1d

@Phillip05166897 I've seen saldhana compared to Kabwe, now irhoud is being described as some kind of late regional ergaster. theres a lot of heidelbergensis traits, LH18 and herto are at least more modern.

English

Strong Multi-Regionalism Enthusiast@Local_Origins1·1d

@Phillip05166897 "suggests that the north african group could be the result of an evolution in isolation of an H. ergaster subpopulation" so would that make the jebel irhoud types the trailing end of that regional ergaster group? makes a pan african development of sapiens complicated

English

PH78-Afram Hominin@Phillip05166897·1d

@Local_Origins1 x.com/Phillip0516689… Yes. In the recent Thomas Quarry study that highlighted the non-metric differences with Antecessor, it essentially replicated the older study comparing Tighenif with Antecessor.

@copperskin722 probably a similar story to the tarim mummies who were almost all ancient North Eurasian, yet culturally picked up behaviours and technology from other groups without mixing.

Skhirat pastoralists barely had EEF admixture, their ancestry was around 3/4 PPNB and 1/4 IBM mostly.

bit of an interesting thought experiment for you nerds given what we know about the extreme plasticity of the human brain, its ability to re-utilise neurons after injury to maintain normal behaviour, see this extreme case cbc.ca/radio/asithapp…

English

Strong Multi-Regionalism Enthusiast@Local_Origins1·2d

the behavioural modernity we see from denisovans and Neanderthals got me thinking about this, how similar sized brains came to advanced culture and thinking, meaning cranial morphology differences in my opinion are not that relevant to what makes us human

English

Strong Multi-Regionalism Enthusiast@Local_Origins1·2d

given how advantageous cognitive performance is, could we rule out Neanderthals and Denisovans had their own alleles which impact those 3 factors, given the polygenic nature of the brain it'd be hard to say they didnt.

English

Strong Multi-Regionalism Enthusiast@Local_Origins1·2d

@CompellingDNA well I agree with having denisovan closer to sapiens than neanderthal, because I think longi clade leads to east asian sapiens, given all the traits east asian erectus shares with denisovans that puts them closer than neanderthals in my mind

English

Highly Compelling@CompellingDNA·2d

@Local_Origins1 Yes, I would think that Denisovans would be closer to Asian erectus. There is not much difference in the age splits though. Only 100ky between Neanderthal and Sapiens, with Denisovans in the middle.

Highly Compelling@CompellingDNA·2d

They have been saying the Out of Africa theory is wrong for half a decade but some still don't want to believe the experts. Homo sapiens are not an African species.

@CompellingDNA the thing i was looking at was how they positioned Chinese erectus and the longi clade, I thought they should be closer together, instead Chinese erectus is on the other side of the neanderthal and heidelbergensis groups.

English

Highly Compelling@CompellingDNA·2d

@Local_Origins1 2019: Bodo, Kabwe lineage is not ancestral to Homo sapiens, Asian lineages have a better morphology for H. sapiens. 2021: Harbin study "shuttle dispersal model". 2024: Yunxian study "LCA originated in Asia". 2026: "Asian erectus is the 1st definite Human 1.5mya..." 🤓

@Phillip05166897 @CompellingDNA I hope theres something there in Peking specimens, however in that time frame you'd expect natural drift and overturn in the genome, so I wouldnt expect much, some advantageous retentions like what is left of neanderthal and Denisovan

English

PH78-Afram Hominin@Phillip05166897·2d

@Local_Origins1 @CompellingDNA While Kabwe genetics are a pipe dream, Peking Man genetics not so much.

English

Highly Compelling@CompellingDNA·3d

Using Morphometric analysis, Daka and Buia skulls fall between Sangiran 17 and Kabwe, ancestral to Heidelbergensis. These 2 skulls share traits with Sangiran and Ergaster, suggesting hybridization. Peking Man is the direct ancestor of Modern Lineages.

@Phillip05166897 @CompellingDNA like if we had kabwe genome would we find that large pieces overlap with modern humans because kabwe like groups contribute to irhoud and so on? before neanderthal was mapped onto modern humans we saw all of our genome as modern

English

Strong Multi-Regionalism Enthusiast@Local_Origins1·2d

@Phillip05166897 @CompellingDNA maybe, but this makes me think about africa, how much of the modern human genome we recognise as modern human is a carry over from whenever the transition happening in africa from heidelbergensis to irhoud (or whatever model you prefer, doesn't matter for the question)...
