First we need to get a couple of factual things correct. The FOXP2 work was
published in Nature, Aug 22, 2002 p. 869 by Enard et al. Their work does
not say 50,000 years for the evolution of FOXP2 but 200,000 years. Klein is
one of those who kind of twists the data to fit his viewpoint--I have read
his recent book.
There are several pieces of evidence against Klein's hypothesis, which is
one that has been around long before Klein. The Hazdabe and Ju|'hoansi
peoples appear to be separated by 112,000 years and they have a rare but
related language. This implies that language was in existence that long ago
in agreement with Enard et al and in disagreement with Klein's twisted view.
Secondly, given that issue, there was no behavioral difference between the
Neanderthals and anatomically moderns for something like the first
60,000-160,000 years of anatomically modern humans' existence. If language
was such a great thing, it didn't distinguish those who supposedly had it
from those like the Neanderthals, who supposedly didn't have it.
Neanderthal hyperglossal canal is as big as ours. This canal carries the
nerves which enable careful control of the tongue. It seems strange that
evolution would evolve such control in both Neanderthals and moderns when
such control wasn't required for one of them.
mtDNA coalescence show that modern humans are descended from a common female
who lived somewhere between 100 and 200 thousand years ago. That means that
any FOXP2 gene change which affected the human populuation would more
easily spread from that time frame.
As to the supposed lack of Neanderthal burial objects, this is just plain
silly. If a stone tool is found on the chest of a modern it is interpreted
as a burial object but if found on a Neanderthal it is far too often
interpreted as an accidental event. Neanderthals at Regourdou constructed a
cairn and laid out Neanderthals along with ritually placed bear bones.
Teshik Tash goat horns were arranged symetrically around the Neanderthal. A
boars jaw was found in the hands of an adult at Skhul and a sculpted stone
was found with an infant neanderthal in Dedireyah Syria. And Neanderthals
did use bone tools (at Regourdou, 80,000 years ago), just not as much as
moderns. One can see http://www.glenn.morton.btinternet.co.uk/chron.htm for
information on the things Neanderthals invented which include coal mining,
the flued hearth, the venus figurine craze, anoxic chemistry and shellfish
exploitation. But we moderns do like to throw rocks at these guys who no
longer can defend themselves.
I would also point out that Neanderthals were not easily conquored.
anatomically modern humans (AMH) stood at the door to Europe, unable to go
there for 60,000 years. They went to China and even possibly Australia
before they were able to enter Europe. The Neanderthals were powerful people
as their muscle attachments show. They would have been a formidible foe and
probably beat the AMH's and took their women. In any event the conquest of
Europe, when it occurred, took over 13,000 years, not exactly a Blitzkrieg.
AMH's are believed to have entered Europe around 42,000 years ago. The last
Neanderthals are dated to something like 28,000 years ago. To say this is
'rapid' is plain silly.
And I don't think the Neanderthal history was 'inconspicuous' given the
things they appear to have invented which we still use. There is also good
genetic evidence that some of their genes flow in modern
Europeans-red/blonde hair, the horizontal oval form of the mandibular
foramen (found in 1% of modern Europeans and almost unknown elsewhere but
found in almost all Neanderthals.) There are other things as well.
So, what do I think of Klein's view? Not much.
