DNA analysis of Peruvian mummy. Mummy's tooth being used in DNA analysis. DNA (deoxyribonucleic acid) can sometimes be recovered from ancient human remains, and studied to help researchers understand the genetics of the pre-Hispanic population of Peru compared to today's population. Mummification, where the remains are preserved by dessication in a dry climate, helps preserve the DNA. Photographed at the University of Rome Tor Vergata, Rome, Italy.
