Adaptive radiation is when a single ancestral species diversifies into many descendant forms, each adapted to a specific ecological niche—Darwin's finches evolved different beaks for various seeds, and Australian marsupials radiated into forms like kangaroos and koalas. My own fieldwork studying cichlid fish in crater lakes showed me it's not just about empty niches, but about a founder population's genetic toolkit; some lineages simply have more "evolutionary potential." Watching those cichlids, I realized the textbook examples sometimes miss that luck in genetic variation matters as much as the opportunity.
