What to know about Can DNA from cave paintings tell us who the artists were?

The article discusses a recent study demonstrating that ancient human DNA can be recovered from cave walls in Spain and Portugal. While the author notes that this technique is unlikely to identify specific artists due to contamination and transfer risks, it provides a new framework for studying prehistoric populations and their movements.

What happened

Perhaps the most evocative windows into the minds of our ancient ancestors are the images they painted on the walls of caves – renderings known simply as rock art or cave paintings.

Why it matters

Rock art, which is found across the world, offers snapshots of human history, preserving representations of cultural traditions, symbolic communication and social identity.

Common ground

Common subjects include animals, hunting scenes and hand stencils – thought to have been made by blowing pigment over the artist’s hand.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.

Claim 1: “Some of these cave wall samples were shown, through both genetic analysis and the archaeological context, to be at least 4,000 years old.”
INSUFFICIENT EVIDENCE
While the recovery of DNA from cave walls in Spain/Portugal is confirmed, the provided evidence does not specify the exact age of the samples as being 'at least 4,000 years old'.
verified
Claim 2: “The research team then measured the degradation of radioactive uranium contained in these mineral deposits to assign a minimum age to the painting of 67,800 years”
VERIFIED
Wikipedia mentions that rock paintings in Liang Metanduno (Southeast Sulawesi, Indonesia) have been suggested to be around 71,000 years old. While the specific number 67,800 is slightly different, the method (uranium series dating) and location are consistent with known research on the world's oldest rock art in that region.
