700,000-Year-Old DNA Found in Siberian Ice Just Rewrote The Story of Humanity

Scientists discovered 700,000-year-old DNA in Siberian mammoth teeth, revealing that genetic material can survive far longer than previously believed and that ancient species like the Columbian mammoth were hybrids formed from different mammoth lineages; this discovery demonstrates that DNA preservation depends on environmental conditions, with cold, dry permafrost preserving genetic material better than warm, humid environments, and that our understanding of human evolution is incomplete because most human ancestors lived in Africa's warm climates where DNA degrades rapidly, unlike the Arctic conditions that preserved mammoth DNA.
