These ghost ancestors have no sequenced genomes, yet their DNA persists in modern humans. One lineage diverged from human ancestors approximately 1.8 million years ago, while the second split roughly 800,000 years ago. One of these lineages still represents roughly 0.5 to 1.1 percent of the analyzed genetic material. The discovery was made possible through a new genetic technique used to reconstruct evolutionary family trees.Why it mattersIdentifying ghost lineages help
