Neanderthal Invasion Led to Hybridization

This is the model for my prehistoric fiction I use in order to 
reconcile the data that has been made available to me by scientific 
studies.

There were lots of different sub-groups of hominids 100 thousand years 
ago all over the "Old World."

Anatomically modern humans occupied Africa and SW Asia to the borders 
of India. However, there were areas in both places that AMHS did not 
occupy.

A massive radiation of neanderthal people and/or genes began around 
90 thousand years ago, and extended into Africa and India.

The explosion of Toba slowed or even halted that Neanderthal radiation.
However, Neanderthals and their genes remained dominant in Europe and 
most of SW Asia until somewhere between 45 thousand and 70 thousand years ago.


Neanderthals occupation of SW Asia cut the genome of Hss in half, with 
mtDNA Eve in Africa and mtDNA LM3 in East Asia.
Possibly mtDNA M and Y hap C were in East Asia too, but another hominid
 was keeping Hss out of India. 
Another hominid was keeping Hss out of most of China and still another 
was keeping Hss out of most of SE Asia. 
Much of this population was assimilated by various Archaic Asian 
hominids as the world recovered from Toba.

There were two subspecies of hominid in South Asia. One is genomically 
considered Neanderthal but did not look like a Neanderthal. The other 
is an unknown species of early homo or austro that likely lived in Sri
Lanka.

The next radiations of genes and peoples were from several "hybrid" 
populations.
The hybrid of Indian "Neanderthal"(Narmada Man) and Hss contained Y Hap 
F, among others.
The hybrid of SW Asian Neanderthal and Hss contained Y hap DE, among 
others 

I don't know which mtDNA haplogroups were contained in these radiations
 - the vikings screwed that map all to hell by trading in women.

The Y Haplogroup F wave slowly assimilated peoples in South Asia and 
South-Central Asia. They kept Y Hap D people out of India. Y Haplogroup 
F became dominant in the population 
and began to diverge into subgroups, extending into parts of SE Asia.

Y Hap DE and C slowly dominated everywhere else, pushing and 
assimilating neanderthals and "denisovans" and groups of 100% Hss people
 with the spread of their wave.

Y Hap A dominant groups in Africa sought refuge in badlands and mixed 
with the Archaic African Introgression hominid. No doubt the latter's 
resitance to Malaria helped in the new enviroment, and helped to keep 
the northerners out.
Y Hap B sought reguge in areas where the big bad genes of Idaltu Man 
still lingered, and he wasn't having any of that Neanderthal crap.
Hence we have Archaic African Introgression and Y Haplogroup A00 in 
Sub-Saharan Africa. 90% of Africans are Y Hap E and have Neanderthal
Introgression. It's just that they've just had 60,000 years to decide 
which Neanderthal genes 
they wanted to keep, which explains their low levels of Neanderthal and 
Denisovan introgression. (Most Africans have neanderthal introgression, 
just not the ones in Sub-Sahara where Archaic African Introgression and
 Y Hap A00 are more common)

But there was another radiation coming, and that one involved the Homo 
Erectus Soloensis "Denisovan," Y Haplogroup K, and microcephalin D.

This Hybrid of Y Hap K Hss, Neanderthal, and the Microcephalin D hominid
 incubated in SE Asia (or South Asia) from 60 thousand to 25 thousand 
years ago. Then it finally invaded India and Central Asia, separating 
the Y Hap E people from the Y Hap D people and killing or out-competing 
most Y Hap DE people in Central Asia.
Also, central Asia has sporadic population in the Paleolithic, so it 
may be that F and DE had previously alternated occupation of most of it depending on conditions up until that time. They may have even sometimes met and mixed, hence 
the basal F and possible Y Hap DE* in Tibet and the Caucasus.


A later radiation of peoples and genes, either Mesolithic or Neolithic, 
involved ASPM-D and agriculture.







We have mostly been talking about cultural exchange between the SE and 
SW after 2500 B.C., but the Bilbo mound is actually during the Archaic 
Period, so I have been reading up on the Archaic today.
Looking at what I can find on the Archaic period in the SW, it didn't 
have as much pottery and favored large points over small points. I would
 tend to link it with the Paleoindians and Paleo-Siberians and 
Cromagnons that preceded each other in turn going back 40 thousand 
years before the Archaic period.
The Archaic SE (and Mesoameric?) has a lot of pottery and more midden 
mounds and stilt houses. So I would link them with the 
proto-austronesians and australoids before them, who had a similar 
lifestyle going back 40,000 years.
So big game hunters vs. boat people. There's a similar situation in 
Europe and the Middle East during the Mesolithic. China and Africa 
are a bit more complicated- the middens and stilt houses are there, 
but both lack a lot of Y Hap P big game hunter groups.
I would not expect to find much artificial cranial modification in
 NW N. American during the Archaic, except where SE or Mesoamerican 
cultural intrusion were also present... but I would definitely expect 
to find it in the SE. There's at least one example in Ga from this 
period, but I'm not sure of the earliest date in Mesoamerica and 
Florida.
I would expect the possibility of finding Y Hap C or Y haplogroups 
within K that are not P,Q, or R in the SE during this period, but I 
would be surprised if we found much in the SW. Especially if it was 
unaccompanied by the incursion of SE or Mesoamerican cultural 
artifacts.
While I don't doubt that these two complexes exchanged cultural 
material and genes during the Archaic Period, it looks to me like 
they mixed a lot more after 3500 B.C. or so. Maybe the biggest 
mix-up between them was even later, as we've already discussed 
on this thread how the Yuchi and others were supplanted in a 
reaction to Colonialism.
It sure would explain why the Yamacraw men were so tall and the 
Yamacraw women so short (if the colonial reports can be relied upon).
