"Lots of the wild animals in the caves have spears in them and blood coming out of their mouths and everything that a hunter would be familiar with," Guthrie told LiveScience. "These were the Ferraris and football games of their time. They painted what was on their minds."
And as with modern teenagers, the ancients had more on their minds than just cars and sports.
"In the graffiti, there is a lot of below-the-belt-art," Guthrie said. "The people in the art are predominantly women, and not a single one has any clothes on."
But these weren't just any women, they were Pleistocene Pamela Andersons adorned with ludicrously huge breasts and hips. The walls were also decorated with graphic depictions of genitalia.
Surprise, surprise! I guess the more things change, the more they stay the same =)
