Thanks for posting. Chapter 12-15 seem very interesting, but I can't get in. Managed to find the abstract of chapter 12 though:

quote:
Facial morphology comprises some of the most distinctive features of early modern humans. The rich fossil record of Morocco allows assessing changes in facial morphology from the late Middle Pleistocene through the Late Pleistocene. Specimens associated with the Aterian industry in Morocco were originally thought to be relatively recent (40–20 ka), but could be much older (35–90 ka). Predating this population are the late Middle Pleistocene specimens of Irhoud. Later in the same geographical area, larger samples are represented by the Iberomaurusian series. We conducted a 3D geometric morphometric analysis of the facial shape of the Aterian specimen Dar es-Soltan II-5, with the aim of deciphering the affinities of this specimen with earlier North African and Levantine fossils, later Upper Paleolithic Eurasian specimens, as well as later North African populations. We used a large comparative sample (n = 191) comprising seven geographic populations of recent humans, Iberomaurusians from Afalou and Taforalt (n = 22), and Middle and Late Pleistocene Eurasian and African fossils. The 3D coordinates of 19 facial landmarks were collected. Specimen landmark configurations were processed with Generalized Procrustes Analysis. Principal Components, Canonical Variates, and cluster analyses were performed and Procrustes distances and Mahalanobis squared distances were calculated. Both Irhoud 1 and Dar es-Soltan II-5 are similar to the early anatomically modern humans from Qafzeh, and the Iberomaurusian sample is closely connected to the Upper Paleolithic European sample.

^^^^ a lot of pages are inaccessable on the googlebooks link
It's an expensive book about $110, used $85 and up

If you PM Sundiata he may have access to parts of it (?)

I haven't looked at any of it yet

Upper Palaeolithic Europeans generally show a morphometric pattern where they're initially more similar to Africans than Europeans, and then later they appear more similar to Europeans due to micro evolution in a Northern non-tropical environment. Note that I said ''more similar'' in both cases.

This closer affinity of the early UP European hunter-gatherers to Africans presumably has a lot to do with the tendency of European UP remains to retain to a larger extend a generalized appearance, which tends mimic what has been pigeon-holed as 'Negroid' affinity (e.g., rectangular eye sockets). But European UP remains are almost all mtDNA U. All the U carrying specimen in the table below (Fu et al 2013) are Upper Palaeolithic Europeans. The rest aren't Upper Palaeolithic (some are recent European skulls, like 'Cro-Magnon I' for instance, which is a medieval European skull and it carries mtDNA T):

They both (UP Europeans and the ancestors of Ibero-Maurusians) probably split off of a U carrying Middle Eastern hunter-gatherer community before the oldest U haplogroup (mtDNA U5) emerged. The emergence of U5 would have occurred after the ancestors of European hunter-gatherers moved into Europe. In my view U6 emerged later in West Asia as it pre-dates the Northern African archaeological cultures its associated with, and there was a settlement hiatus in Northern Africa when U6 emerged.

^^Generally they resemble Africans more. A number of
scholars see this as evidence of tropically adapted types
more like Africans in place and later cold adaptation
happening, but with some residual tropical traits still showing.

".. while the Late Upper Paleolithic and
Mesolithic humans have significantly
higher (i.e., tropically-adapted) brachial
and crural indices than do recent
Europeans, they also have shorter (i.e.,
cold-adapted) limbs. The somewhat
paradoxical retention of "tropical"
indices in the context of more
"cold-adapted" limb length is best
explained as evidence for Replacement in
the European Late Pleistocene, followed
by gradual cold adaptation in glacial
Europe."

(Holliday, Trenton (1999)
Brachial and crural indices of European
Late Upper Paleolithic and Mesolithic
humans. Journal of Human Evolution.
Volume 36, Issue 5, May 1999, Pages
549-566)

If you haven't already on Historum or elsewhere,
you will run into assorted "biodiversity" types
trying to tout a "human revolution" in Europe
in the Upper Paleolithic, contrasting "progress in Europe"
with "backward" Africa. This is not merely web
forum fantasy, but claims made by an assortment of
racialist and even some mainstream academics in part
within the last decade and a half- comparatively recent-
and the (direct or indirect) mentality of "progress in Europe"
versus "static" or "stagnating" Africa is still around.
Other serious scholars however have examined the claim
and debunked it in detail. Turns out that the
vaunted progenitors of the alleged "human revolution"
resembled tropical Africans, not the much hyped "Caucasoids."

Since you asked for a refresher, and have been
tangling with these racialist types recently, recap posted
below in case you once again need to apply the hammer..

--------------------------------------------------------------


 -

Advanced cognitive, technological and behavioral patterns derive from
Africa. Dubbed the "Human Revolution" by some researchers, they lead up to the
expansion of humans from Africa to other parts of the world, circa 60-40kya. Other
scholars argue for a more gradual continuum of advances deeply rooted in
Africa that spread worldwide. In either scenario, whether relatively rapid advance
or gradual accumulation, the cognitive, technological and behavioral advances
took place WITHIN Africa.


QUOTE:
"Recent research has provided increasing support for the origins of anatomically
and genetically "modern" human populations in Africa between 150,000 and 200,000
years ago, followed by a major dispersal of these populations to both Asia and Europe
sometime after ca. 65,000 before present (B.P.). However, the central question of why it
took these populations {approx}100,000 years to disperse from Africa to other regions of
the world has never been clearly resolved. It is suggested here that the answer may lie
partly in the results of recent DNA studies of present-day African populations, combined
with a spate of new archaeological discoveries in Africa. Studies of both the mitochondrial
DNA (mtDNA) mismatch patterns in modern African populations and related mtDNA
lineage-analysis patterns point to a major demographic expansion centered broadly within
the time range from 80,000 to 60,000 B.P., probably deriving from a small geographical
region of Africa.

Recent archaeological discoveries in southern and eastern Africa suggest that, at approximately
the same time, there was a major increase in the complexity of the technological, economic, social,
and cognitive behavior of certain African groups,
which could have led to a major demographic
expansion of these groups in competition with other, adjacent groups. It is suggested that this
complex of behavioral changes (possibly triggered by the rapid environmental changes around
the transition from oxygen isotope stage 5 to stage 4) could have led not only to the expansion of
the L2 and L3 mitochondrial lineages over the whole of Africa but also to the ensuing dispersal of
these modern populations over most regions of Asia, Australasia, and Europe, and their replacement
(with or without interbreeding) of the preceding "archaic" populations in these regions."

---Mellars, Paul (2006) Why did modern human populations disperse from Africa ca. 60,000 years ago?
A new model. PNAS, 2006, 103(25), pp. 9381-9386

 -


Advanced cognitive, artistic and behavioral patterns and technology like more refined tools
are found in Africa long before similar patterns arose in Europe. The migration of tropical
African types to Europe in the Cro-Magnon era brought these cognitive, cultural and behavioral
advances to Neanderthal Europe.


"A more gradual "revolution" position is now held [by Paul Mellars].. a period of
accelerated change in Africa between about 60,000 and 80,000 years ago, as shown
by the following developments recorded in South African cave sites: new and better-
techniques for producing long thin flakes of stone blades; specialized tools called end
scrapers and burins, which were probably used for working skins and bones, the
[production of tiny stone segments that must have mounted on handles of wood or
bone to make composite tools, complexly shaped stone tools such as 'leaf points',
relatively complex bone tools; marine shells perforated to make necklaces or bracelets,
red ochre (natural iron oxide) engraved with geometric designs suggesting early artwork,;
greater permanence and differentiated occupation areas in caves; new subsistence practices
such as the exploitation of marine fish as well as shellfish; and perhaps intentional burning
of undergrowth to encourage the growth of underground plant resources such as tubers.
Mellars suggests that a neurological switch to modernity in the brain alongside rapid
Climatic fluctuations, could have been the driving forces behind this period of heightened
cultural innovations.."

"The most impressive site for early evidence of symbolism however, is Blombos Cave in South
Africa, with a record stretching well beyond 70,000 years ago.. The stone tools in these levels
include Still Bay points, beautifully shaped thin lanceolate spear points, flaked on both sides.
They also show the earliest application of a refined stone tool-making technique known as
pressure flaking, some 55,000 years before its best-known manifestation in the Soultrean
industry of EUrope. Slabs of red ochre were excavated from various levels, including the
deepest ones, with wavy, fan or mesh-shaped patterns carefully engraved on them..
Hundreds [beads made from seashells] have now been excavated from Blombos,
and most show signs of piercing, with many holes also displaying signs of wear.. The
shells have a natural shiny luster, but the color seems to have been modified by rubbing
with hematite in some cases and by heating to darken the shells in other cases, so they
may have been strung in different-colored patterns.. "

--Chris Stringer (2012) Lone Survivors: How we came to be the only human on earth 150-155

Some archaeologists criticize notions of a "human revolution" suddenly
occurring after humans exited Africa for Asia and Europe. Instead they
argue, the supposed "revolutionary" changes in cognition, symbol
manipulation, advanced technology, trade etc were ALREADY occurring
WITHIN Africa, long before any migration out. There is no need for a
'eureka moment' of 'progress' upon leaving Africa. 'Progress' was already
well underway and long in place within Africa, without the need for
'eureka' moments.
QUOTE:

"This is because by focusing on changes that occurred at the Middle
Paleolithic/Upper Paleolithic or Middle Stone Age/Later Stone Age
transitions (in Europe and Africa, respectively), there is a failure to
appreciate the depth and breadth of the African Middle Stone Age record
that preceded the time of the supposed revolution by at least 100,000
years. In their view, [McBrearty and Brooks 2000] 'modern' features such
as advanced technologies, increased geographic range, specialized hunting,
fishing and shell-fishing, long distance trade, and the symbolic use of
pigments had already developed in a broad range of Middle Stone Age
industries right across Africa, between 100,000 and 250,000 years ago.
This suggested to them that an early assembly of the package of modern
human behaviors occurred in Africa, followed by much later export to the
rest of the world. Thus the origin of our species, both behaviorally and
morphologically, was linked to early developments in Middle Stone Age
technology, and not to changes that occurred much later.. 'this quest for
this 'eureka moment' reveals a great deal about the needs, desired and
aspirations of archaeologists, but obscures rather than illuminates events in
the past.."

--Chris Stringer (2012) Lone Survivors: How we came to be the only
human on earth 128-29

---------------------------------------------------------

Their "backflow card" ain't gonna work either because
said "backflowees" look like tropical Africans
to begin with not the much vaunted paler types


 -


Beware certain "generalized Caucasoid" claims. This involves defining
away Africoid affinities or features as "generalized" but at the
same time not treating "European" features the same way. The double
standard only runs one way- if a feature has African affinities-
airbrush it away as "generalized" but otherwise call it "Caucasoid"
or equivalent. This double-standard however is contradicted by Africa's
diversity, and clear tropical body/limb proportion affinities of its migrating
peoples


For example, Jantz and Ousley 2003 assert that:
"Upper Paleolithic crania are, for the most part, larger
and more generalized versions of recent Europeans."
(AJPA 121(2))


But their wording gives the game away. They achieve a "match" with
"recent Europeans" because features deemed to have African affinities
are defined away as "generalized." The African irritant thus eliminated,
they can then go on to cluster all else with Europe. Two central
points undermine this method:

-----------CRANIA
Africa has the most diversity in crania in the world. It has almost any skull
variation on earth. This diversity DECREASES the farther one goes from Africa.
As one of the world's foremost palentologists Chris Stringer notes:


"Africa today has the greatest internal genetic variation of any inhabited
continent and its skull shapes show the highest variation. This is usually
attributed to its greater size, larger ancient populations and deepest
timelines for humanity."

----Chris Stringer (2012) Lone Survivors: How we came to be the only
human on earth p260

-----------TROPICAL LIMB/BODY ADAPTATIONS
"Erik Trinkhaus noted that the Cro-Magnons who livd in much the same
environments as Neanderthals were more like recent African populations in
body shape than Neanderthals. And the same thing now seems to apply to the
earliest modern skeleton we have from the north of Ice Age China."
----Chris Stringer (2012) Lone Survivors: How we came to be the only
human on earth p105

[i].. Thus, the discovery of tropically adapted
hominids in the region would therefore
likely indicate population dispersal from
the TROPICS, and the most logical
geographic source for such an influx is
Africa.
In this regard, Trinkaus (1981,
1984, 1995) and Ruff (1994) have
argued that the high brachial and crural
indices, narrow biiliac breadths, and
small relative femoral head sizes of the
Qafzeh-Skhul hominids suggest an
influx of African genes associated with
the emergence of modern humans in the
region."

Crossroads: Modern Human Emergence in Western

The ideas of this book are actually not new. Even Stephen Oppenheimer in his book The Real Eve expresses the idea that the Anatomically Modern Human species may have originated specifically in the North African region based on the findings of Jebel Irhoud in Morocco and the earliest known AMH remains OOA in Skhul and Qafzeh. Whether the origination of our species lies in so-called 'sub-Sahara' or the Saharan or supra-Saharan areas, it is still in Africa.

So you agree then that U6 or U in general in Africa is the result of back-migration(?) What about its ancestor hg R whose subclade R0 is found in Africa in significant frequencies?? What do you make of Keita's theory regarding the geneflow between North Africa and Southwest 'Eurasia'?

^Yeah, of course I argue that its the result of back-migration, as I've done in the past with the data from Henn et al 2012, Sánchez-Quinto et al 2012 and several others. R0 in Northern Africa is not basal. The only haplogroups in Northern Africa today that are candidate ancestries for these Terminal Pleistocene Maghrebi remains are M1(b) and U6(a). What Keita said is just a theory from 2005, which doesn't even seem plausible given what we know now about the most recent TMRCAs of these mtDNAs and the North African specific genetic component.

The Berber specific SNP component, as well as mtDNA M1 and U6 split off of whatever there was in West Asia ~34-30kya according to most recent research, how is that consistent with the indigenous evolution of pre-OOA left overs that stayed in Africa? Why is the Northern African specific component so close to West Asians, if this genetic SNP component was really ancestry that evolved in Northern Africa ever since proto-Eurasians left Africa? The Northern African specific genetic component is evidently closer to the West Asian genetic component than the East Asian genetic component is to the latter. How can this be under your interpretation of the data?

Keita's stuff comes from a period when M1 was thought to be potentially just as old as basal M1 in South Asia, now we know that simply isn't supported by the evidence, thanks to Gonzales et al 2007. Instead of moving on all I see is everyone still latching on to a sinking ship. Oh, but it isn't a sinking ship I hear you say? Well, then what is the multi-disciplinary evidence for them being indigenous Africans? I invite you to explain it here, knowing I will likely get nothing of substance.

^ No, don't get me wrong. I don't have any bias or agenda at all but am trying to get to the bottom of this issue which is why I asked for specifics. I haven't been keeping up with the latest studies and what studies I do read on this issue I do so through this forum. I frankly have no problem with the idea of back-migration since we are talking about populations that are right next door to Africa and obviously not of the "Caucasoid" type many Euronuts love to stress.

Not to overstay my welcome, as I'm not exactly posting in line with the OP parameters, but Nazlet Khater seems to correlate with L3k, which moved from the Ethiopian region to North East Africa 30-40kya, per Soares et al 2011. Whatever its affinity, its mandible strongly clusters with MSA Sub-Saharan Africans per Pinhasi's analysis.

Yes I'm aware of what Pinhasi and Soares state about the skeletal data, but I was wondering what you think of the possible genetic data. L3K does seem like a good guess in terms of Ethiopian origins but then again nothing is certain until actual DNA from Nazlet Khater or related finds are tested.

What do you mean with how did they enter Africa? Are you referring to the aridity of the Sahara? The Ibero-Maurusian sites were found in coastal Maghreb, as well as the other sites (e.g., Dabban). The North African coastal regions weren't affected by the aridity of the Sahara to the point of becoming uninhabitable; they remained a traversable corridor.
So are you suggesting they entered North Africa from the Sinai area and thus acknowledge a relation with the contemporary Kebaran Culture??

quote:
Someone should make another thread if they want to discuss this further.
We have how many threads already on the Oranians/Ibero-marusians??

By the way, I suddenly remember something.

You say the Oranian culture has no ties to anything in Sub-Sahara well what about the following point brought up by Troll Patrol?

Figure 8.13. Taforalt, Morocco, under renewed excavation. The site preserves a long sequence of Iberomaurisian and, below these, Aterian deposits. (Courtesy and copyright Nick Barton and Ian Cartwright.) whole. This was the practice of removing two or more of the upper incisors, usually around puberty and from both males and females, something that probably served as both a rite of passage and an ethnic marker (Close and Wendorf 1990), just as it does in parts of sub-Saharan Africa today (e.g., van Reenen 1987). Cranial and postcranial malformations are also apparent and may indicate pronounced endogamy at a much more localised level (Hadjouis 2002), perhaps supported by the degree of variability between different site samples noted by Irish (2000).

--Lawrence Barham, The First Africans: African Archaeology from the Earliest Toolmakers to Most Recent Foragers (Cambridge World Archaeology)

Is not the practice of avulsion of the incisors proof of connection to so-called "Sub-Saharans"?? The practice still survives today in the Kordofan region of Sudan among other areas of Africa.

I never denied a cultural connection with Sub-Saharan Africans. The backed bladelet toolkit is clearly shared between the two, and the sharing of this industry with Nile Valley groups as well as mtDNA flow back and forth between Northwest Africa and Eastern African in the form of U6a and U6a1 indicates contact.

As for tooth evulsion, there is no evidence for it in Late Pleistocene, Terminal Pleistocene or Early Holocene Africa outside of the Maghreb. It occurs in the terminal pleistocene/Early Holocene Natufian remains though. In Africa it starts appearing outside of the Maghreb after the mid-holocene, as evidenced by Asselar Man in Mali, while its has always been absent in the Nile Valley. Its presence in Mali seems to be related with the Ibero-Maursian expansion to the South, which is perhaps corroborated by certain mtDNAs in West Africa, like prehistoric European U5 and U6. Unless I'm missing something, these manifestations of prehistoric tooth evulsion don't look like they bespeak an African origin for the trait.

And yes, I'm thinking along the lines of an entry from the Sinai, and no, I don't think they have anything to do with Kebarans for the simple fact that they would have been identified as such by now if this were the case.

Green = Ibero-Maursian
light Blue = Capsian

The Ibero-Maursian sites are East North African coast ending at Tunisia. I don't see any in Libya or Egypt. It seems improbable that if Ibero-Maursians has a Eurasian component and hence the name Ibero-Maursians, -Iberian, they would not have come across Gibralter but instead come through the Sinai,
unless I'm not following right. - however it's far from impossible.
In Eurasia U lineages correspond to Spain, Italy and Scandinavia not to the Near East although there may be no DNA recovered from Ibero-Maursian sites to , I don't about it.

The Iberomaurusian enigma: North African progenitor or dead end?
Joel D. Irishf1
Department of Anthropology, University of Alaska Fairbanks, Fairbanks, Alaska, 99775-7720, U.S.A.


Abstract
Data obtained during an ongoing dental investigation of African populations address two long-standing, hotly debated questions. First, was there genetic continuity between Late Pleistocene Iberomaurusians and later northwest Africans (e.g., Capsians, Berbers, Guanche)? Second, were skeletally-robust Iberomaurusians and northeast African Nubians variants of the same population? Iberomaurusians from Taforalt in Morocco and Afalou-Bou-Rhummel in Algeria, Nubians from Jebel Sahaba in Sudan, post-Pleistocene Capsians from Algeria and Tunisia, and a series of other samples were statistically compared using 29 discrete dental traits to help estimate diachronic local and regional affinities. Results revealed: (1) a relationship between the Iberomaurusians, particularly those from Taforalt, and later Maghreb and other North African samples, and (2) a divergence among contemporaneous Iberomaurusians and Nubian samples. Thus, some measure of long-term population continuity in the Maghreb and surrounding region is supported, whereas greater North African population heterogenity during the Late Pleistocene is implied.

^The earliest Ibero-Maurusian sites are in Algeria, and they then gradually move up to Morocco. The epicentre of mtDNA U is in the Near East, not Europe, as the original U carrying European AMHs came from the Near East.

U5 and U6 have an ancient divergence before the settlement of Europe, not a more recent one after the settlement of Europe. We expect a more recent divergence around the time of the appearances of Ibero-Maurusian sites 20kya, if, as you suggest, they had more shared history in Europe after it was settled by AMHs ~40kya:

quote:
For the first point, we assigned a mode age of 45 ka and a 95th percentile of 60 ka for the split between the U5 and U6 lineages, based on the hypothesis that some of the first settlers of Europe [51] were carrying haplogroup U that would later evolve into U5 [11]. Considering this, the age of the U5-U6 split would be a minimum of 45 ka old. Reliable archaeological dates are minimum estimates of a first settlement, justifying the use of the exponential distribution.
--Peirera et al 2010

Also, M generally is an East Eurasian haplogroup (South Asia, East Asia, Melanesia) haplogroup, its not associated with the earliest European AMHs, and also not very prominent in modern Europe. This would seem at odds with the link M1 is said to have with Ibero-Maurusians in the literature, if they passed through the Strait of Gibraltar. This all makes Europe an unlikely source for the Ibero-Maurusians.

Why do Scandinavian Sami all the way up in Northern Europe have the highest levels of U5 ?
U5b ranged from 56.8% in Norwegian Sami to 26.5% in Swedish Sami.

but doesn't the tool kit show similarity to the Iberians?
If not then would Levantine-Maurusians be a more appropriate name?

They probably have been more successful at retaining the genetic signature of Franco-Cantabrain refugium population, as they're also big on mtDNA V--a marker said to be associated with this community that would repopulate Europe after the ice age.
