The New York Times reports on the publication of an archeological article outlining the discovery of 37,000-year-old cave drawings that show our earliest ancestors had a taste for pornography:

The drawings include what appear to be images of the female vulva, illustrated by circles with small slits on one side. “You see this again and again and again,” Dr. White said. There are also very simple images, in profile, of animals, including horses and lionlike big cats, he said.

The work was discovered on a collapsed roof of a rock shelter at the Abri Castanet site in the Vézère River valley in southwest France. Humans at the time lived in such shelters, Dr. White said, and it was a period of cultural naissance.
