The sudden emergence of human art 50,000 years ago did not stem from a single genetic mutation but from polygenic co-evolution—David Reich's 2016 study found no selective sweeps in modern human ancestors more recent than 400,000-500,000 years ago, suggesting cognitive leaps likely arose from expanding social networks rather than biological mutations.
