Ancient CivilizationsAncient Human DNA Discovered Hidden Inside Paleolithic Cave Walls for the First Time Posted on June 28, 2026 by Administrator 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.”
