Investigating ancient human DNA preservation on cave walls and in rock art
What this contributes
Investigates ancient human DNA in cave-wall pigments and rock-art environments.

Trace survival does not imply intact genomes or preserved memories.
Why it belongs here
A sample's value depends on collection, chain of custody, storage history and quality controls. Cryopreservation research ranges from cells and tissues to experimental organ preservation. Preserving a specimen, preserving its structure and restoring its function are distinct outcomes.
