Within the DNA of fish, powerful genetic mechanisms have been uncovered that may explain one of nature’s greatest mysteries: how new species form with such incredible speed. In Lake Malawi, hundreds of cichlid fish species evolved at lightning pace, and scientists now believe that “flipped” sections of DNA, known as chromosomal inversions, hold the key. These inversions effectively lock together beneficial gene combinations, creating “supergenes” that enable fish to rapidly adapt to diverse environmental conditions, from deep-water regions to sandy shores.
