Bear DNA is clue to age of Chauvet cave art 
19 April 2011 by _Michael Marshall_ 
(http://www.newscientist.com/search?rbauthors=Michael+Marshall)  
 
 
EXPLORING a gorge in south-east France in 1994 for prehistoric  artefacts, 
Jean-Marie Chauvet hit the jackpot. After squeezing through a narrow  
passage, he found himself in a _hidden cavern_ 
(http://www.newscientist.com/article/mg14519621.400-cave-art-work-of-great-talent.html)
 , the walls of which 
were _covered with paintings of animals_ 
(http://www.newscientist.com/article/mg14519621.400-cave-art-work-of-great-talent.html)
 . 
But dating the beautiful images - which featured in Werner  Herzog's recent 
documentary film _Cave of Forgotten Dreams_ 
(http://www.newscientist.com/blogs/culturelab/2011/03/ancient-paintings-unlocked-from-history.html)
  - has 
led to an _ugly spat_ 
(http://www.newscientist.com/article/dn3631-doubt-cast-on-age-of-oldest-human-art.html)
  between archaeologists. Could the bones 
of cave bears  settle the debate? 
_Within a year_ 
(http://www.newscientist.com/article/mg15020281.000-passions-run-high-over-french-cave-art.html)
  of Chauvet's discovery, _radiocarbon 
dating_ 
(http://www.newscientist.com/article/mg14619820.400-ancient-masters-put-painting-in-perspective.html)
  suggested the images were between 30,000 
and  32,000 years old, making them almost twice the age of the famous 
_Lascaux cave art_ (http://www.lascaux.culture.fr/?lng=en#/en/00.xml)  in 
south-west France (see map). The result "polarised the  archaeological world", 
says 
Andrew Lawson, a freelance archaeologist based in  Salisbury, UK. 
Lawson accepts the radiocarbon findings. "Nowhere else in  western Europe 
do we know of sophisticated art this early," he says. But _Paul Pettitt_ 
(http://www.sheffield.ac.uk/archaeology/staff/pettitt.html)  of the University 
of Sheffield,  UK, is adamant that the paintings cannot be that old. The 
dating study doesn't  stand up, he claims, insisting that the paintings' 
advanced style is enough to  mark them as recent. To suggest otherwise, he 
says, 
would be like claiming to  have found "a Renaissance painting in a Roman 
villa". 
Despite a comprehensive radiocarbon study published in 2001 that  seemed to 
confirm that the paintings were indeed 30,000 years old  (Nature, _DOI: 
10.1038/35097160_ (http://dx.doi.org/10.1038/35097160) ), Pettitt and his 
colleagues were  unconvinced. Two years later they argued that the cave walls 
were still  chemically active, so the radiocarbon dating could have been thrown 
out by  changes over the millennia to the pigments used to create the 
paintings  (Antiquity, vol 77, p 134). 
To try to settle the controversy, Jean-Marc Elalouf of the  Institute of 
Biology and Technology in Saclay, France, and his team have turned  to the 
remains of cave bears. Along with mammoths and other huge mammals, cave  bears 
(Ursus spelaeus) dominated the European landscape until the end of  the last 
ice age. 
The Chauvet cave contains several depictions of cave bears, and  Elalouf 
argues that these must have been painted while the bears still thrived  in the 
area. To pin down when the bears disappeared, his team collected 38  
samples of cave bear remains in the Chauvet cave and  
(http://www.newscientist.com/article/dn7462-dna-of-ancient-bears-successfully-sequenced.html)
 . 
They found that almost all the samples were genetically similar,  
suggesting the cave bear population was small, isolated and therefore  
vulnerable. 
Radiocarbon dating showed the samples were all between 37,000 and  29,000 
years old, hinting that by the end of that period they were extinct, at  least 
locally. Samples from a nearby cave, Deux-Ouvertures, gave similar results  
(Journal of Archaeological Science, _DOI: 10.1016/j.jas.2011.03.033_ 
(http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6WH8-52HS637-2&_user=88627
79&_coverDate=04/02/2011&_rdoc=1&_fmt=high&_orig=gateway&_origin=gateway&_so
rt=d&_docanchor=&view=c&_acct=C000000593&_version=1&_urlVersion=0&_userid=88
62779&md5=fb69e1ba22fe4c584a43fff8cc7404de&searchtype=a) ). 
Given the age of the cave bear remains, "it is clear that the  paintings 
are very ancient", says Elalouf. _Michael Knapp_ 
(http://anatomy.otago.ac.nz/index.php?option=com_content&task=view&id=544&Itemid=46)
  of the University 
of Otago in  Dunedin, New Zealand, who also studies cave bears, says he has 
no doubts about  the DNA analysis. 
While we do not know exactly _when cave bears became extinct_ 
(http://dx.doi.org/10.1111/j.1502-3885.2008.00071.x) , all reliably dated 
remains in  
Europe are at least 24,000 years old, says _Martina Pacher_ 
(http://www.oeaw.ac.at/kfq/pacheren.html)  of the Commission of Quaternary 
Research in  Vienna, 
Austria. "So the results at Chauvet are not surprising, and I agree with  
their conclusions," she says. 
"We now have an independent line of evidence that the bears [in  Chauvet] 
date to before 29,000 years ago," Lawson says. "That bolsters the case  for 
an early date." 
Pettitt remains unconvinced, calling the new research "sloppy".  He says 
that the team is trying to extrapolate the regional spread of the bears  over 
time by relying on evidence from just two caves. 
Pettitt also questions whether the paintings show cave bears at  all: brown 
bears lived in the area long after the cave bears were gone. But  Elalouf 
says the two species can be distinguished by skull shape, and that the  
paintings definitely show cave bears.

Sorry,

It was Maurice Herzog who climbed Annapurna, the first summit over 8,000 meters 
to be climbed and the 10th highest mountain in the world.  He climbed it in 
1950 along with a couple of other folks including a Frenchman named Gaston 
Rebuffat pronounced Gastly Rabittfat in Texan.

The book Herzog wrote about that expedition, Annapurna, is a must-read for any

10.1016/j.jas.2011.03.033<http://www.sciencedirect.com/science?_ob=ArticleURL&_udi=B6WH8-52HS637-2&_user=8862779&_coverDate=04%2F02%2F2011&_rdoc=1&_fmt=high&_orig=gateway&_origin=gateway&_sort=d&_docanchor=&view=c&_acct=C000000593&_version=1&_urlVersion=0&_userid=8862779&md5=fb69e1ba22fe4c584a43fff8cc7404de&searchtype=a>).

Given the age of the cave bear remains, "it is clear that the paintings are 
very ancient", says Elalouf. Michael 
Knapp<http://anatomy.otago.ac.nz/index.php?option=com_content&task=view&id=544&Itemid=46>
 of the University of Otago in Dunedin, New Zealand, who also studies cave 
bears, says he has no doubts about the DNA analysis.

While we do not know exactly when cave bears became 
extinct<http://dx.doi.org/10.1111/j.1502-3885.2008.00071.x>, all reliably dated 
remains in Europe are at least 24,000 years old, says Martina 
Pacher<http://www.oeaw.ac.at/kfq/pacheren.html> of the Commission of Quaternary 
Research in Vienna, Austria. "So the results at Chauvet are not surprising, and 
I agree with their conclusions," she says.

"We now have an independent line of evidence that the bears [in Chauvet] date 
to before 29,000 years ago," Lawson says. "That bolsters the case for an early 
date."

Pettitt remains unconvinced, calling the new research "sloppy". He says that 
the team is trying to extrapolate the regional spread of the bears over time by 
relying on evidence from just two caves.

Pettitt also questions whether the paintings show cave bears at all: brown 
bears lived in the area long after the cave bears were gone. But Elalouf says 
the two species can be distinguished by skull shape, and that the paintings 
definitely show cave bears.

You are cordially invited to attend the Underground Texas Grotto meeting
tonight April 20, 2011



The meeting is on Wednesday from 7:45 P.M. - 9:00 P.M.

University of Texas Campus in 2.48 Painter Hall

NOTE:  THE ROOM NUMBER CHANGE to 2.48 PAI

http://www.utexas.edu/maps/main/buildings/pai.html



Pete Strickland will be presenting the Program of the evening that will
share some of his caving adventures.  Pete has been an active caver for
decades and has visited a wealth of cave systems.  Come out to visit with
friends from the extended Austin Texas caver community.



For information on Underground Texas Grotto activities, please see
www.utgrotto.org    All of our information including officer contact info,
trips reports, new caver training, event calendar, and posting links to
beginner trips or vertical rope training are available.



Before the meetings, we sometimes meet at Sao Paulo  www.saopaulos.net  for
a happy hour special.  This area is the best place to park and meet folks
walking over to the meeting.  Then after the official meeting, we continue
with the decades long tradition to reconvene for burgers, beer, and tall
tales of caving at Posse East.  www.posse-east.com



The UT Grotto needs you, the caver with photos and a story to share about
your adventures, scientific research, or something else really cool.  Contact
Gary



Sincerely,



Gary Franklin

UT Grotto Vice Chair & Program Organizer
