Scientists discovered something impossible in Chernobyl's radioactive ruins - life is thriving where nothing should survive. Animals aren't just living in lethal radiation zones, they're evolving faster than nature should allow. From Chernobyl to Bikini Atoll, creatures are activating ancient genetic sequences designed to process radiation. These same genes appear in human DNA, raising profound questions about our own origins. The implications stretch from Earth's ancient past to humanity's future among the stars. What we're learning about life in Earth's most radioactive places is changing our understanding of human potential.
