Studies of ancient human deoxyribonucleic acid (DNA) attempt to shed light on the genetic relationships among individuals representing archaic or extinct human populations, and between these individuals and modern humans. These studies are limited by several factors, including the contamination of ancient samples with modern human DNA, the limited availability of nuclear DNA and difficulties in interpretation of results, due to the fact that modern, typically geographically defined human populations are not associated with diagnostic mitochondrial DNA (mtDNA) sequences.
