“Visit the caves of Pech Merle, Font-de-Gaume and Rouffignac in southern France and you will witness some of the most breathtaking art our planet has to offer.
“Not surprisingly, these paintings attract tens of thousands of visitors every year. However, there is another aspect to this art that often escapes attention, but which is now providing scientists with fresh insights into our recent evolution. Instead of studying those magnificent galloping horses and bisons, researchers are investigating the symbols painted beside them.”
Yes very interesting LS, thanks for the link. It's a shame they didn't show any of the paintings so that the symbols referred to could be seen as well.
