Ancient human DNA found in cave paintings for the first time

Ancient cave walls, long thought to speak only through images, may hold a hidden layer of information: human DNA. A new paleogenetic study suggests that even rock art painted thousands of years ago could preserve genetic traces of the people who created it.

An international team of scientists is investigating the potential of this 'genetic archive.' While the visual art on cave walls has been studied for centuries, the possibility of extracting DNA offers a new avenue for understanding the past. Researchers are now working to determine how reliable this genetic evidence is and what it can reveal about the actual artists.

The study aims to unlock further insights into the lives and identities of ancient human populations. The findings could potentially shed light on migration patterns, social structures, or even the daily lives of the people who left these prehistoric marks. The research is ongoing as scientists refine methods for extracting and analyzing ancient DNA from such challenging contexts.
