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.
Genetic research reveals a timeline of human evolution linking cognitive abilities, brain structure, and mental health vulnerabilities. Intelligence-linked genes appeared ~500,000 years ago, followed by psychiatric disorders.
Explore cosmic threats to Earth, including magnetic field flips, meteorite impacts, and supernovae, and their potential impact on human evolution and Neanderthal extinction. Were ancient humans affected?
