Origin of Cro-Magnon Humans

© Lori Lappin, the Witch of WITCHCRAFTS ARTISAN ALCHEMY®


Both my U5b1 ancestral genetic motherline and paternal I2 fatherline are scientifically proven Cro-Magnon lineages.

A new Chinese theory (12 July 2016, Nature, Vol 535, Issue 7611) on human origins adds more support to the idea that European Cro-Magnon archaic humans (whose origin has never been identified) may have possibly derived from a Middle Eastern source population of Homo heidelbergensis and subsequently evolved in South Asia. My own genetic data overwhelmingly support the Chinese theory. According to my own genetic data, I have a significant lingering trace of South Asian genes, but no significant lingering trace of African genes. The Chinese theory identifies a Middle Eastern source population of Homo heidelbergensis as the common source population from which all modern humans descend.

If the Chinese theory is true, it also explains why Europeans and Asians are somewhat similar to one another, given that early archaic European Cro-Magnon evolution may have occurred in Asia as well as the fact that both Europeans and Asians have prehistorically interbred with other archaic humans who evolved in Eurasia (namely, Neanderthal and Denisovans at the very least), while Native Africans prehistorically interbred with other archaic humans who evolved in Africa. It has been scientifically proven that about 13% of the sub-Saharan gene pool comes from an earlier population of pre-modern hominins called Paleoafricans.

Furthermore, information from a well respected scientific anthropologist (Dienekes Pontikos) also support to the Chinese theory of human origins suggesting that the Homo sapiens ancestral lineage (via Homo heidelbergensis) may have first evolved outside of Africa (in Asia or the Middle East), with a partial migration of archaic humans from a "ME/Asian" source population into Africa (given that so-called "Afrasians" have no Paleoafrican admixture and Paleoafricans are the only known lineage found in some modern humans which is indigenous to and only found in Africa). This also supports the genetic closeness of (Europids) Europeans and (Mongolids) Asians (as both are of entirely Afrasian stock) in contradistinction to other modern human populations (excluding the Australasids which are also of entirely Afrasian stock) which are grouped as "significantly Paleoafrican" (Sanids, Pygmids and Negrids) or as varying degrees of "Afrasian-Paleoafrican admixtures" (Aethiopids). Just as native Africans have no admixture from archaic hominins (Neanderthals and Denisovans) who evolved in Eurasia, native Eurasians have no admixture from archaic hominins (Paleoafricans) which evolved only in Africa.:

It is common to distinguish between Africans and non-Africans, with the former being much more genetically diverse than the latter. But, the real "gap" in human origins seems to be between the really old Africans ("Paleoafricans") and the rest ("Afrasians").

The Paleoafrican element is entirely confined to Africa, while the Afrasian one is found in both Africa and Eurasia. Indeed, modern humans can be entirely split into two groups: (i) a group of "pure" Afrasians which includes all non-Africans, and (ii) a group of Afrasian-Paleoafricans which includes all non-Caucasoid Africans. Human groups of entirely Paleoafrican origin, unhybridized with the younger Afrasians are no longer in existence.

The Afrasians are a recent branch of humankind, and one which was for a great length of time separated reproductively from the Paleoafricans. This accounts for the reduced genetic diversity of Eurasians who are descended entirely from the Afrasian branch; by contrast, Sub-Saharan Africans and East Africans are the result of the intermixture of the Afrasians with the Paleoafricans, and this accounts for the high genetic diversity and antiquity of these populations.

The Chinese theory makes sense, better fits the scientific data, and explains the observable differences we find among modern humans.

Additional Information - Modern human origins: multiregional evolution of autosomes and East Asia origin of Y and mtDNA:

"Recent studies have established that genetic diversities are mostly maintained by selection, therefore rendering the present molecular model of human origins untenable. Using improved methods and public data, we have revisited human evolution and derived an age of 1.91-1.96 million years for the first split in modern human autosomes. We found evidence of modern Y and mtDNA originating in East Asia and dispersing via hybridization with archaic humans."
