Guide to Patagonia's Monsters & Mysterious beings

I have written a book on this intriguing subject which has just been published.
In this blog I will post excerpts and other interesting texts on this fascinating subject.

Another paper on "Out of China" (H sapiens originated in China)


A few days ago I wrote a post about an Asian origin for modern humans, written by Shi Huang. Today I found an earlier paper where Huang is one of the authors Modern human origins: multiregional evolution of autosomes and East Asia origin of Y and mtDNA (Dejian Yuan et al., 2018). As expected mankind originated in China and spread across the globe (into Africa too!).


The paper is quite interesting as it details its objections to the current Out of Africa theory and also highlights some interesting points:


On Negritos and Australian Aboriginals: "Analyses of autosomes, Y and mtDNA all suggest that Denisovan like humans were archaic Africans with Eurasian admixtures and ancestors of South Asia Negritos and Aboriginal Australians.".


"Origins of Negritos and Aboriginal Australians. The Andamanese and the African pygmies seem obviously related in multiple aspects, including traits, Y relationship with the African megahaplogroup ABDE, and mtDNA haplotype M being closely related to African L.
... Using the published genomes of 10 individuals from the Jarawa (JAR) and Onge (ONG) populations in the Andaman Islands (19), we found that Andamanese are relatively closer to Africans...
We also examined the Aboriginal Australian (AUA) samples ... These results showed similarity between AUA and Negritos, indicating similar ancestry in Neanderthals and Denisovans.
"


On Africans, Chimpanzees, Denisovans and Neanderthals: "... previous studies have found Neanderthals to be outgroup to AMH and used D-statistics to show Neanderthal gene flow into non-Africans but oddly not Africans (9, 10).
The assumption of D-statistics is that all modern groups are equidistant to chimpanzees so that presence of derived alleles (different from chimpanzees) was due to gene flow from Neanderthal. If in fact Africans are closer to chimpanzees or carrying more ancestral alleles in general, the conclusion of gene flow into non-Africans would become invalid. We examined this by measuring genetic distance between 1000 genomes and 10 previously sequenced chimpanzee genomes (49). Using the random 255K SNPs set, we found closer hom distance between Africans and chimpanzees than between non-Africans and chimpanzees....
Making use of the published Neanderthal genomes (9, 10, 50), we calculated the genetic distance in slow SNPs between 1000 genomes and Neanderthals (Altai, Vindija 33.16, 33.25, 33.26, and Mezmaiskaya) or Denisovan (Fig. 4A). These ancient genomes showed closer distance to Africans except Vi33.25 to ASN and Vi33.26 to AMR. Denisovan was closer to Africans than Neanderthals were...
"


The previous conclusions are completely opposite to current prevailing theories (Africans lack links to both Denisovans and Neanderthals as any admixture with these groups took place in Eurasia with Eurasian people that migrated out of Africa).


On SE Asian features in Africa: "Fossils or traits indicating AMH migration from East Asia into Africa or Europe have been noted before. First, native Africans such as Khoisans are well known to have certain East Asian features such as shoveling teeth, epicanthic fold, and lighter skins. Mbuti pygmies look very much like the Andamanese. The much lower frequency of shoveling teeth in African fossils and Khoisan relative to ancient and modern Chinese suggests that this type of teeth could only originate in China with its African presence due to migration. The type of shoveling teeth found in Neanderthals and Pleistocene Homo from Atapuerca-Sima de los Huesos may either be a different type from that of Asians and Africans or come from early disposal of Homo from Asia to Europe (81, 82)...".


I found the article amusing and their arguments against the "Out of Africa" theory worth investigating in depth.
