Genetic drift Memes

The social etiquette of not asking about age or salary pales in comparison to evolutionary biology's greatest mystery: why birds keep accidentally vacationing in Hawaii and deciding to stay forever. Those isolated islands are basically the evolutionary equivalent of a Vegas wedding chapel—birds show up, make impulsive decisions, and suddenly they're committed to a whole new lifestyle with specialized beaks. Darwin's finches got nothing on Hawaii's avian casino of genetic drift! The archipelago's isolation creates the perfect natural laboratory for allopatric speciation—where birds check in, but they never check out the same. Next time you're blown off course, consider it an evolutionary opportunity.
