The role of the Neanderthal genome just leapt into serious prominence. The African component provided the naked skin. We have that much right. The neanderthal was fur covered and I have a recent original sighting of a remote village which conforms to both the body hair and the red fur color as well as the robust stature. This evidence was reported before recent work which confirms all that.
Thus European man is a fairly recent, in the last 60,000 years, hybrid of Nenderthal and the naked African with all the implied hybrid vigor
The actual genesis of the Neanderthal also needs to be worked out. Actually this is all getting more exciting and i think we need to toss all ideas in the closet until an awful lot of genetic work is completed. Most of what we think we known is obviously flawed at least.

Essentially this says that the European male lineages include a
pre-modern "Out Of Africa" component from the Neanderthal age. That
would be in the Neanderthal age, and the time distance between the two
populations is pretty exactly the span of the Neanderthals in Europe. I
don't think any of the reviewers have remarked on that aspect of this
yet. The Out of Africa branch as identified here is definitely the
"Naked", tropical-African variety of Homo sapiens as we commonly recognise it: the non-African branch here identified would be the "Hairy" component
Re-Examining the "Out of Africa" Theory and the Origin of Europeoids (Caucasoids) in Light of DNA Genealogy
ABSTRACT
Seven thousand five hundred fifty-six (7556) haplotypes of 46 subclades in 17 major haplogroups were considered in terms of their base (ancestral) haplotypes and timespans to their common ancestors, for the purposes of designing of time-balanced haplogroup tree. It was found that African haplogroup A (originated 132,000 ± 12,000 years before present) is very remote time-wise from all other haplogroups, which have a separate common ancestor, named β-haplogroup, and originated 64,000 ± 6000 ybp. It includes a family of Europeoid (Caucasoid) haplogroups from F through T that originated 58,000 ± 5000 ybp. A downstream common ancestor for haplogroup A and β-haplogroup, coined the α-haplogroup emerged 160,000 ± 12,000 ybp. A territorial origin of haplogroups α- and β-remains unknown; however, the most likely origin for each of them is a vast triangle stretched from Central Europe in the west through the Russian Plain to the east and to Levant to the south. Haplogroup B is descended from β-haplogroup (and not from haplogroup A, from which it is very distant, and separated by as much as 123,000 years of “lat- eral” mutational evolution) likely migrated to Africa after 46,000 ybp. The finding that the Europeoid haplogroups did not descend from “African” haplogroups A or B is supported by the fact that bearers of the Europeoid haplogroups, as well as all non-African haplogroups do not carry either SNPs M91, P97, M31, P82, M23, M114, P262, M32, M59, P289, P291, P102, M13, M171, M118 (haplogroup A and its subclades SNPs) or M60, M181, P90 (haplogroup B), as it was shown recently in “Walk through Y” FTDNA Project (the reference is incorporated therein) on several hundred people from various haplogroups.

Introduction
This study concerns the origin of anatomically modern humans, which
presumably belong to Y chromosomal haplogroupsA through T according to
the classification developed in humangenetics and DNA phylogeny of man.
This paper 1) sets forth atimeframe for the origin of Europeoids
(Caucasoids); 2) identifies their position among all haplogroups
(tribes) known todayon the haplogroup tree; and 3) offers evidence to
re-examinethe validity of the "Out of Africa" concept.
The principal difference of our approach from those knownin human
genetics is that our methodology is based on the identification of
branches of haplotypes in each haplogroup and its subclade (each branch
is descended from its only common ancestor), and, in each case, is
calculated a timespan from a com-mon ancestor of the branch by verifying
that the branch is in-deed derived from one common ancestor and by
using the crite-ria described in (Klyosov, 2009a; Rozhanskii &
Klyosov, 2011;Rozhanskii, 2011). As a result, we obtained a chronology
of allavailable branches in each haplogroup and in their total
en-tirety—from A to T (in the current classification). In other words,
for each haplotype we successfully identified its place inthe whole
multi-haplogroup system of mankind. It is reasonableto assume that
haplotypes of the whole of mankind form a con-tinuous system, albeit
locally interrupted by "population bot-tlenecks" which essentially
disrupt the initially continuous fab-ric of haplotypes. This fabric can
be reconstructed based on itsfragments and in the same manner as the
kinetics of chemicalreactions can be reconstructed based on relatively
few experi-mental points. This analogy is rather close since mutations
inhaplotypes obey the same laws of chemical kinetics, this was discussed
in the first paper of this series (Rozhanskii & Klyosov,2011).
Thanks largely in part to geneticists, the "Out of Africa"concept was
popularized during the last two decades, yet it was never directly
proven; however, for many specialists its appeal was undeniably
convincing. The concept was based primarily on the premise that Africa
possesses the highest variability, or variance, of the human DNA and its
segments. Set apart, it is not a strong argument because a mix of
different DNA lineages also results in a high variability and, as we show
below, it islargely what occurs in Africa. Moreover, a genomic gap
exists between some Africans and non-Africans, which has also
been interpreted as an argument that the latter descended from Afri-cans.
A more plausible interpretation might have been that bothcurrent
Africans and non-Africans descended separately from amore ancient common
ancestor, thus forming a proverbial fork.A region where this downstream
common ancestor arose wouldnot necessarily be in Africa. In fact, it
was never proven that helived in Africa.Research into this question has
served as the basis for and thesubject of our work. We have found that a
great diversity of Y chromosomal haplotypes in Africa is a result of
the mixing of several very distant lineages, some of them not
necessarilyAfrican, and that Europeiods (at least) do not contain
"African"SNPs (those of haplogroups A or B). These important findings
put a proverbial dent in the "Out of Africa" theory.
Results and Discussion
The 22 marker haplotypes, which are the "slowest" in termsof their
mutation rate constant, described in (Klyosov, 2011a,2011b; Rozhanskii
& Klyosov, 2011) were mainly used in this study. They are best
suited for chronological calculations downto 100,000 years and deeper in
time. This is because one muta-tion in these haplotypes occurs on
average once in 4250 years,while in 67 marker haplotypes, for example,
one mutation oc-curs—on average—once in 208 years (ibid). However, the
22marker haplotypes include a part of the last panel of the 67marker
haplotypes and hence, 67 marker haplotypes wereneeded for the study.
Haplogroup A
Extended haplotypes of haplogroup A collected in variousdatabases
(YSearch, FTDNA Projects), split into at least four different and
distinctive DNA lineages, each with its base hap-lotype. This is
essentially represented with a series of 32 marker haplotypes ( Figure
1) and 37 marker haplotypes ( Figure 2).In a simple, uncomplicated case,
the base haplotype is equi-valent to the ancestral haplotype in the
lineage. This is obvious in recent lineages, in which most haplotypes
still represent the non-mutated ancestral haplotype. For more ancient
lineages the

A series of previously unreported haplotypes from Cameroon was assigned to A1b subclade according to STR values, being nearly identical to those found in Bahamas ( Simms et al., 2011).

Figure 2
base haplotype is obtained by the minimization of mutations in the
haplotype dataset; therefore, the base haplotype represents the deduced
ancestral haplotype. The four base haplotypes of haplogroup A in the 22
marker format are as follows:
12 11 11 - 9 11 - 10 - 10 9 12 12 7 10 8 null 13 11 16 1014 9 11 11
12 10 11 - 7 13 - 8 - 10 8 15 17 6 10 9 12 13 11 16 8 1311 11 12
13 11 12 - 10 11 - 16 - 10 9 14 14 8 8 8 9 12 11 12 8 1212 11 11
12 13 10 - 10 11 - 10 - 11 8 15 15 8 9 8 null 10 9 14 8 128 11 12
These base haplotypes have been assigned to subclades A3b2,A1a, A(P97+,
SRY10831.1-), and A(M23-, M32-, P108-,SRY10831.1-), respectively. It was
calculated that the common ancestors of the branches lived 5500, 5000,
600 years before present (ybp), and the last one is an individual
haplotype. It is clear that these four haplotypes are tremendously
distant from each other, and this is taking into account the extremely
low mutation rates of the markers. The deduced base haplotype for
haplogroup A from the available data is as follows:12 11 11 - 9 11 - 10 - 10 8 14 15 7 10 8 12 13 11 16 8 139 11 12
Since alleles in the four haplotypes above vary significantly,the
permutation method was applied (Klyosov, 2009a) for cal-culation of a
timespan to their common ancestor. The averagesquared sum of all
mutations in the four haplotypes aboveequals to 984, and the number of
conditional generations to acommon ancestor is 984/22/2/16/.00027 =
5177. That is,132,000 years to a common ancestor of all the available
haplo-types of haplogroup A. In the formula above, 22 is the number of
markers in each haplotype; sixteen (16) is the square of thenumber of
haplotypes in the dataset, 2 is introduced because thenumber of
mutations was counted twice (all permutations),and .00027 is the
mutation rate constant per marker in the 22marker haplotypes (Klyosov,
2011a, 2011b). A correction for
back mutations is not required in the permutation method(Klyosov,
2009a).Pairwise calculations of the dataset above give, as it should be,
slightly lower values of timespans to a common ancestor.For example,
base haplotypes of the A1a and A3b2 subclades (see Figure 2) differ by
25 mutations in all 22 markers, which places their common ancestor at
4167
→
8576 conditionalgenerations, that is 112,000 ybp. Two haplotypes with
null-mutation differ by 27 mutations, which places their commonancestor
at 4500
→
9922 conditional generations, that is127,000 years to a common ancestor
(see Materials and Meth-ods for the principles of calculations). This
gives an additionalsupport of the obtained "age" of haplogroup A as
132,000 ±20,000 years.
Haplogroup B
A similar approach was applied to haplogroup B, and thefollowing 22
marker base haplotype was obtained for a com-mon ancestor who lived
46,000 ybp (Klyosov, 2011b):11 12 11 - 11 11 - 10 - 11 8 16 16 8 10 8 12
10 11 15 8 1211 12 11It differs from the base 22 marker haplotype of
haplogroup A by 18 mutations, which gives 18/.006 = 3000 generations.
Witha correction factor (for back mutations) of 1.633, the
resultconstitutes 123,000 years between common ancestors of hap-logroup A
and B. Because they lived 132 and 46 thousandyears before present,
respectively, their common ancestor livedapproximately 150,000 years
before present (see Materials andMethods).The ISOGG (International
Society of Genetic Genealogy)annual review in 2010 and earlier stated "
The BR haplogroupsplit off from haplogroup A 55,000 years before present ( bp)
.It probably appeared in North East Africa". Since the ISOGG-2012
stated, "The A haplogroup is thought to have been defined about 60,000
years bp
"http://www.isogg.org/tree/ISOGG_YDNATreeTrunk.html
then haplogroups A and B should be separated by only several thousand
years, or by 2 - 3 mutations in their slow 22 marker base haplotypes. It
is not so, and between their base haplotypes there are as many as 18
mutations in the 22 markers, which translates to 123 thousand years (see
above).This finding indicates that haplogroup B did not descend from
haplogroup A. Rather, they both descended from a com-mon ancestor who
lived ~150,000 ybp, and he was not necessarily living in Africa. Since
he belonged to a haplogroup up-stream from haplogroups A and B, his
haplogroup can be named "alpha-haplogroup". It is a matter of taste and
belief to call it "Adam" or not.
Haplogroups C through T
The same methodology was applied to 7415 of 67 marker haplotypes of all known haplogroups and their subclades, re-duced to the slow 22 marker haplotypes, taken from databasesYSearch and SMGF and a multitude of FTDNA Projects (see Appendix). The base haplotypes of principal haplogroups andsome of their subclades, including those of haplogroups A andB, are listed below, and chronology of their appearance is shown in Figure 3
Pairwise
calculations of mutation distances between the base haplotype of
haplogroup A and each of the base haplotypes of other haplogroups place a
common ancestor of the α-haplogroupat 160,000 ± 12,000 years before
present. For example, 18 mu-tations between A and B base haplotypes, as
it was describedabove, result in 150,000 ybp for their common ancestor.
Twenty-one (21) mutations with haplogroup DE base haplotype give167,000
ybp for their common ancestor. Twenty-three (23)mutations with
haplogroup H base haplotype result in 171,000ybp for their common
ancestor with haplogroup A. For hap-logroup I (21 mutations) it is
161,000 ybp. For haplogroup Q(22 mutations) it is 166,000 ybp. For
haplogroup R (21 muta-tions) it is 160,000 ybp. The distance in 19
mutations betweenthe base haplotypes of haplogroup A and β -haplogroup
places α-haplogroup at 165,000 ybp. Clearly, the base haplotype of
haplogroup A and its subclades is very remote from all other
haplogroups.Similar pairwise calculations with the base haplotype of
haplogroup B as well with all other haplogroups (besides A) place a
common ancestor of beta-haplogroup to 64,000 ± 6000years before present
(see Figure 3). This haplogroup is close toor identical with the BT
haplogroup according to the currentclassification. Figure 3 shows a
topology of the current haplogroup tree. The α-haplogroup which is the
ancestral one with respect to both African (left branch) and non-African
haplogroups (right branch) arose around 160,000 ybp, and 132,000 ybp
gave riseto haplogroup A. Another, quite different branch, had formed
afork, then apparently went through a population bottleneck around 70 -
60 thousand ybp (perhaps the Toba event), andgave rise to β -haplogroup,
ancestral to non-African haplogroups, 64,000 ± 6000 ybp. Apparently,
haplogroup B was initially not of an African origin. It could have
migrated to Africa and mixed there with a local population. A common
ancestor of the present-day bearers of haplogroup B lived 46,000 ybp. A
similar story had occurred with a group of bearers of haplogroup
R1b1around 4000 ybp, who ventured to the center of African continent
during their westward migration along the African Mediterranean shore,
and became a Negroid population having an unusual (for Africa)
haplogroup (Cruciani et al., 2010; Klyosov,2012).The Mongoloid and
Austronesian haplogroup C split ~36,000 ybp and gradually populated
regions of Central Asia, Australia and Oceania. Haplogroup DE split to D
and E around 42,000 ybp, and currently populates vast territory from
North Africa to the west to Korea and Japan to the east.The family of
haplogroup from F through T is largely theEuropeoid (Caucasoid) family.
Most of bearers of these hap-logroups remained Europeoids; however, some
populations have acquired racial features of the prevailing races in a
given region, recently or in the long past.Based on the calculations
given in this study, we know thatthe far most bearers of haplogroup A
live in Africa, and they lived there probably all or most of those
132,000 years since haplogroup A arose. It cannot be excluded, of
course, that hap-logroup A might have been appeared elsewhere and then
mi-grated to Africa. However, there is no reason to believe (andfewer
reasons to insist) that the Europeoid family originated in Africa.
Lack of the African SNP (Haplogroup A) in Non-Africans
Lack of the African SNP (Haplogroup A) in Non-Africans
A critical datapoint has emerged that disproves the "Out of Africa" concept; specifically, recent data shows that non-African people have neither M91, P97, M31, P82, M23, M114,P262, M32, M59, P289, P291, P102, M13, M171, M118 (haplogroup A and its subclades SNPs), nor M60, M181, P90 (hap-logroup B SNPs) in their Y-chromosomes. In fact, according to the data obtained from the "Walk Through the Y" (chromosome) international project conducted by Family Tree DNA (Texas and Arizona) [see Appendix] not one non-African participant out of more than 400 individuals in the Project tested positive to any of thirteen "African" sub-clades of haplogroup A, SNPs for which indicated above. If to take, for example, bearers of R1a haplogroup, they each have the ladder of SNPs from M42 and M139 (haplogroup BT, butnot haplogroup B, which, as it was described above, split andmigrated to Africa around 46,000 ybp or earlier), through M168and M294 (haplogroup CT), P143 (haplogroup CF), M89 andP158 (haplogroup F), L15 and L16 (haplogroup IJK), M9(haplogroup K), М 74, L138, P69, P230, P243, P244, P280,P284, P286 (haplogroup P), М 207, P224, P227, P229, P232,P280, P285 (haplogroup R), P231, P241, P242, Р 245, Р 294haplogroup R1), L145 and L146 (haplogroup R1), L120 and
A haplogroup tree
of Y chromosome derived from base haplotypes of haplogroups and
subclades and their TMRCAs, systemati-cally calculated as described in
this study. 7415 haplotypes from 46 subclades of 17 major haplogroups
have been considered for the tree design. Timescale on the vertical axis
shows thousands of years from the common ancestors of the haplogroups
and sub-clades. The tree shows the alpha-haplogroup, which is the
ancestral haplogroup of the African and non-African haplogroups, andthe
beta-haplogroup, which is the ancestral haplogroup, close or identical
with BT haplogroup in the current classification. The left branch
represents haplogroup A (arose ~132,000 ybp) and its subclades. The
right branch of haplogroups F through R including T) represent
Europeoids (Caucasoids) arose ~58,000 years before present. Haplogroup B
(arose ~46,000 ybp) migrated to Africa, theMongoloid and Austronesian
haplogroup C split ~36,000 ybp, apparently Middle Eastern haplogroups DE
split ~42,000 ybp. Aregion of the origin of the alpha-haplogroup
~160,000 ybp remains unknown. The Europeoid family of haplogroups arose
appar-ently in the triangle between Central Europe on the west, the
Russian Plain (Eastern European Plain) on the east and Levant on the
south.

the SNP have been identified, which should be found according to the
phylogeny of R1a, but SNPs of the all examined subclades of haplogroup A
were completely absent.The same pattern was observed with all other
bearers of non-African haplogroups. The bearers of haplogroup A were
exclusively positive to M91 SNP, characteristic of that haplogroup.

There are, however, four distinct SNPs which present in both Africans
and Europeans of haplogroup R1a1, taken the latter asan example. They

described in this study, are compatible with each other and undeniably
indicate that non-African people, bearersof haplogroups from C to T, did
not descend from the “African”haplogroups A or B. Their origin is
likely not in Africa. Ahigher variance of the DNA in Africa, which was a
cornerstoneof the “Out of Africa” theory, is explained by
Figure 3
, in which haplogroup A has been evolving (mutation-wise) for 132,000
years, while the non-European haplogroups are muchyounger. Hence, there
is a lower variability in the latter. Thesame is related to language
variability, which has also beenused as an argument of the African
origin of non-Africans. We believe that those arguments upon which the
“Out of Africa”theory was based were, in fact, conjectural, incomplete
and notactually data-driven. Therefore, we are left holding the question
of the origin of
Homo sapiens.Based on palaeoarchaeological evidence, the region, where
anatomically modern humans have likely originated, is com- prised of a
vast territory from Central Europe in the west to the Russian Plain in
the east to Levant in the south. Each of these regions is renowned for
discoveries of the oldest skeletal re-mains of modern humans dating back
to 42,000 - 44,000 ybp. To date, none of these sub-regions has clear
and unequivocal advances in this regard.
Materials and Methods
7556 haplotypes, predominantly 67 marker ones, have been collected in
databases FTNDA, YSearch and SMGF (Sorenson Database), and reduced to
the slow 22 marker haplotype panels:
DYS426, DYS388, DYS392, DYS455, DYS454, DYS438,DYS531, DYS578,
DYS395S1a, DYS395S1b, DYS590, DYS641,DYS472, DYS425, DYS594, DYS436,
DYS490, DYS450,DYS617, DYS568, DYS640, DYS492.
The methodology of haplotype datasets analysis was de-scribed in
(Klyosov, 2009a, 2009b; Rozhanskii & Klyosov,2011). The most
important research component involved dissecting the dataset to branches
of haplotypes, each branch descended from one common ancestor. This was
examined andverified by the logarithmic method (no mutation counting)
cou- pled with the linear method (based on mutation counting),
asdescribed in (Klyosov, 2009a; Rozhanskii, 2011). The mutationrate
constant for the 22 marker haplotypes equals to .0060
mu-tation/haplotype/conditional generation of 25 years, or
.00027mutation/marker/generation (Klyosov, 2011a; Rozhanskii
&Klyosov, 2011). Haplotype trees were composed using softwarePHYLIP,
Phylogeny Inference Package program (see Klyosov,2009a, 2009b and
references therein). Corrections for back mutations were introduced as
described in (Klyosov, 2009a;Rozhanskii & Klyosov, 2011). Margins of
error were calculatedas described in (Klyosov, 2009a). Permutation
method of TMRCA (time to the most recent common ancestor) calculationwas
described in (Klyosov, 2009a).Base haplotypes in the dataset were
determined by minimi-zation of mutations; by definition, the base
haplotype is onewhich has the minimum collective number of mutations in
thedataset. The base haplotype is the ancestral haplotype or theclosest
approximation to the latter.
Example: Calculation of a timespan to a common ancestor for the base haplotype for haplogroup A (132,000 ybp)
12 11 11 - 9 11 - 10 - 10 8 14 15 7 10 8 12 13 11 16 8 139 11 12 (

)and that for the
β

11 12 11 - 11 11 - 10 - 11 8 15 16 8 10 8 12 10 12 12 8 1211 11 12 (

)
19 mutations between the two base haplotypes results in19/.006 = 3167
conditional generations (25 years each) withouta correction for back
mutations. The number of mutations per marker is 19/22 = .8636. By
employing formula for back mutations (Klyosov, 2009a), we find that a
correction for back mutation is
11exp.86362
= 1.686
Therefore, the “lateral” time difference between two base haplotypes is
3167 × 1.686 = 5340 conditional generations of 25 year, that is 133,500
years. A common ancestor of the both base haplotypes, A and β-haplotype,
lived (133,500 + 64,000 +132,000)/2 = 164,750 ybp. Assignments of
haplotypes to haplogroups and subclades were based on their SNP
classification, as provided in the data- bases. In some instances it was
additionally supported by calculating their position of the phylogenic
trees from their respective STR data.
