Some finches managed to grow their beak a bit larger in response to the drought; they survived and reproduced, and passed the character of an enlarged beak to their offspring. Finches with larger beak had a higher probability of surviving the drought. Thus, there was strong selection on variation in beak size, resulting in an increase in the population mean beak size.
