A landmark Nature study has revealed how the Amazon molly — an entirely female fish species that reproduces by cloning — has survived for over 100,000 years despite evolutionary theory predicting its extinction after just 10,000. The secret lies in gene conversion, a DNA "copy-and-paste" repair mechanism that purges harmful mutations without sex, with implications reaching from evolutionary biology to cancer research.
