Scientists found genetic signatures in ancient & modern humans linked to migration, risk-taking, and brain development. These traits, favored by evolution, may influence long-distance movement and even local economic growth, suggesting a biological basis beyond social factors.
Scientists are using ancient DNA to identify 'ghost lineages'—extinct groups that left no fossils but exist in our genomes. This research reveals a complex, 'bushy' model of human evolution and interbreeding.
Mitochondrial transfer techniques, like pronuclear transfer, help prevent inherited mitochondrial diseases by replacing faulty mitochondria. Eight children appear healthy after the procedure.
Exploring ancient DNA reveals secrets of Chernobyl survivors' resilience and human history. Analyzing genomes helps understand past migrations, diseases, and adaptations for future insights.
