Molecular biology is now giving clues to the origins of Homo sapiens. Researchers have utilized mitochondrial deoxyribonucleic acid (mtdna) because it accumulates mutations much faster than the nuclear DNA so therefore a useful tool for calibrating mutation rates. Mitochondrial DNA is inherited only through the maternal line and it does not mix or become diluted with paternal DNA. -fagan info
