What is the term for a feature that allows an organism to survive better in its environment?

 For questions #2-4 use the scenario below to help answer.  A biologist spent many years researching the rate of evolutionary change in the finch populations of a group of islands. It was determined that the average beak size (both length and mass) of finches in a certain population increased dramatically during an intense drought between 1981 and 1987. During the drought, there was a reduction in the number of plants producing thin-walled seeds.
