Discovery of two mysterious human lineages
Geneticists have uncovered genetic evidence of two mysterious ancient human lineages, for which no direct fossil remains have been found. One lineage lived in Africa more than 50,000 years ago and interbred with modern humans, leaving its marks in about 0.5% to 1% of contemporary human genes. The second lineage is much older, diverging from the first approximately 1.8 million years ago, and it interacted with Denisovans in Eurasia over 200,000 years ago. The study, which analyzed more than 500 genomes, reveals that traces of these groups still exist in the modern human genome, broadening our understanding of human evolution and enhancing knowledge of genetic changes over time and how humans adapted to various environments.
