What Were They Thinking? Cracking the Cave Art Code
Monday is “Darwin Day,” the anniversary of the birth of Charles Darwin, the British naturalist who changed how humans understand the living world. Cave-art researcher Genevieve von Petzinger last week spoke at The University of Alabama at Birmingham to help mark the occasion. Von Petzinger studies geometric patterns found in caves all over Europe. As she tells WBHM’s Dan Carsen, in college she’d excavated Roman artifacts … but that wasn’t quite right for her. A few highlights:
Von Petzinger decided Roman artifacts weren’t old enough. “Which sounds really funny, right? Something 2,000 years old was too young. But I was like, this already feels like things have happened. I’m more interested in the origins of things. So I study some of the oldest art in the world — the art from caves in Europe from the Ice Age, between 10,000 and 40,000 years old.”
It’s Not Just the Deer and the Spears
“What fascinates me are the little squiggly marks, what we call the geometric signs — is there a pattern? Are they repeating them? How many signs are there? And, you know, do the same ones appear across space and time? Can we figure out things with them? And the answer is yes.”
The Signs that Repeat
“We have 32 signs, which is actually a very small number, that repeat at caves all across Europe for like 30,000 years … I think what we’re probably dealing with is some important ideas or concepts, almost like putting the one word on the wall as opposed to the whole sentence … what I’m digging into now is I think a thematic level: we might be able to start saying, “maybe this is a weapon, or maybe this is their house.”
Cave Wall, Window, and Computer?
“It’s a really unusual window into their minds. This is like trying to understand how they’re making sense of the world around them. And doing something like making graphic marks is actually a very mentally sophisticated thing to do because they’re actually storing information outside their body, which sounds funny but, I mean, what is a computer? So it’s that mental shift to understanding that information isn’t just in your head, or in your verbal words, but that you can actually store it and share it — a hugely important concept.”
Neanderthal Lineage
“We used to think that Neanderthals and humans weren’t related. And then we’ve realized now that they’ve interbred. And according to my genome, I’m almost 4 percent Neanderthal on my mother’s side. So there we go.”

Memory loss: As AI gobbles up chips, prices for devices may rise
Demand for memory chips currently exceeds supply and there's very little chance of that changing any time soon. More chips for AI means less available for other products such as computers and phones and that could drive up those prices too.
