Q2

On the Galapagos Islands, researchers have been monitoring a population of finches for decades. These finches eat seeds, and can crack seeds of different sizes depending on the size (depth) of their beak: finches with large beaks are good at cracking and eating large, hard seeds; finches with small beaks do well on small seeds. In 1977, a very severe drought caused seed production to drop drastically; most of the few plants that did flower and produced seeds were plants that make large, hard seeds. As a consequence, many finches that did not have a large enough beak to crack the hard seeds, died of starvation. A ● Figure A below shows how much variation there was in beak size among individuals before (1976) and after (1978) the drought year. The mean (small triangle on the horizontal axis) shifted from about 8.8 mm to about 9.8 mm. Figure B shows midoffspring values of beak size plotted agains midparent values, in 1976 (black dots) and 1978 (open circles). The straights lines show the regressions across the 1976 data points (lower, plain line) and the 1978 data points (upper, dashed line).
