Researchers Discover Ancient Human DNA Hidden Inside Paleolithic Cave Walls
A handprint on a cave wall has fingers spread wide. The pigment is made from powdered red ochre mixed with water or animal fat. The hand was placed against the rock while someone blew pigment through a hollow bone. When the small hand was removed, it left behind a negative image with uneven edges. Generations of Ice Age people came to this wall, leaving other faded marks, dots, waves, and animal shapes. People of the distant past left a message for visitors: “I was here.”
Now, scientists have shown for the first time that ancient human DNA can survive for thousands of years on cave walls. This remarkable finding presents promising research options for examining prehistoric human activity. The interdisciplinary study was conducted in collaboration with the First Art Project, led by researchers from Spain and Portugal in direct coordination with institutions in the UK, China, and Germany.
