Neandertals Occupying Open-Air Site in Israel

There is evidence of Neandertal occupation at an open-air site in northern Israel called Ein Qashish.  From the researchers:

Whereas many open-air settlements are thought to be short-lived and chosen for specialized tasks, 'Ein Qashish appears to be the site of repeated occupations each of which hosted a range of general activities, indicating a stable and consistent settlement system. The authors suggest that within a complex settlement system, open-air sites may have been more important for prehistoric humans than previously thought.

The vast majority of Neandertal sites in France and the Levant are cave sites so this represents a sharp contrast in societal behavioral patterns.  The site appears to have been repeatedly occupied by Neandertals from around 70 to possibly 54 thousand years ago, representing potentially an 18 thousand year span, although the span is probably 70-60 kya.  Although the hominin remains at the site are fragmentary,  a designation of Neandertal was made based on the morphology of a third molar and a complete femur. 

This is more evidence that Neandertal society and life-styles were much more complex and advanced than most researchers have allowed.

New Data on Neandertal Anatomy

Anatomists have reconstructed the rib cage of the Kebara 2 Neandertal to get a better understanding of the trunk of our nearest relatives.  Science Daily has the story:

An international team of scientists has completed the first 3D virtual reconstruction of the ribcage of the most complete Neanderthal skeleton unearthed to date, potentially shedding new light on how this ancient human moved and breathed.

The team, which included researchers from universities in Spain, Israel, and the United States, including the University of Washington, focused on the thorax -- the area of the body containing the rib cage and upper spine, which forms a cavity to house the heart and lungs.

What did they find?

The reconstruction of the thorax, coupled with the team's earlier finding, shows ribs that connect to the spine in an inward direction, forcing the chest cavity outward and allowing the spine to tilt slightly back, with little of the lumbar curve that is part of the modern human skeletal structure. "The differences between a Neanderthal and modern human thorax are striking," said Markus Bastir, senior research scientist at the Laboratory of Virtual Anthropology at the National Museum of Natural History in Spain.

"The Neanderthal spine is located more inside the thorax, which provides more stability," said Gomez-Olivencia. "Also, the thorax is wider in its lower part." This shape of the rib cage suggests a larger diaphragm and thus, greater lung capacity.

In my anthropology class, I teach about the effects of Bergmann's and Allen's rules of body morphology. In the case of Neandertals, the adaptations to the cold were shortened distal limb segments, a large, projecting mid-face and a tendency toward barrel-chestedness. The new study reinforces these ideas.

Interestingly, it should be noted that the Kebara Neandertal is found in Israel, not known for its cold climate.  It is hypothesized that the Neandertal population came down from Eastern Europe to escape the cold (the tundra line was at Vienna).  What is peculiar about the Kebara 2 Neandertal is that it consists only of a body.  Whether he died and his head fell in a stream or some animal carried it off, there is no cranium.  Oddly, what we do have is one of the bones that is preserved least in the fossil record: a hyoid.  It is this that has given us the most information about the Neandertal vocal tract.

Fun stuff.

New Tooth in Israel

A research team from Tel Aviv University is touting a new find as being from anatomically modern Homo sapiens. The story, from the AP has this to say:

A Tel Aviv University team excavating a cave in central Israel said Monday they found teeth about 400,000 years old. The earliest Homo sapiens remains found until now are half that old.

Archaeologist Avi Gopher said Monday further research is needed to solidify the claim. If it does, he says, "this changes the whole picture of evolution."

The story is a bit confused since Neandertals are considered Homo sapiens as well, just not modern ones. It is ordinarily not very easy to distinguish between Neandertal teeth and modern teeth, except for size and that is not always a good indicator. Ordinarily, you have to have more diagnostic areas of the skeleton. Given that the earliest moderns we now have come from the site of Herto, dated to 160 ky, it is not likely that the tooth is modern. If it were, it would mean that there is a modern populaton running around during a time when the transition from Homo erectus/ergaster to archaic Homo sapiens (Neandertals and their kin) was occurring everywhere else. It would also mean that the Levantine populations that followed them 300k years later were more archaic than those represented by the tooth. That would be a tad peculiar.
