Referring to figure 1, it depicts the relationship that time has with finch population and average beak depth when there is an average rainfall of 25 cm. It justifies the first hypothesis as the finch population remains almost the same over the span of five years and the beak depths of the birds are essentially constant. However, in reference to figure 2 challenges the second hypothesis as the overall trends from the results demonstrate that although the finch population does decrease with drought, their average beak depth increases over time. Likewise, in reference to figure 3 challenges the third hypothesis as the general trends exhibit that the finch population increases, but their beak depths decrease over a five year period. The trends expressed by figure 2 and figure 3 show the progress of the finches adapting to changes in the environment over
