O The proportions of finches having different beak sizes/shapes change across generations. The rare birds have historically been killed by gamekeepers and others because they predate on grouse populations, which are maintained for shooting. C.

We found a simple, mathematical relationship to describe and characterize the beak shape, said Gary Choi, a former graduate student at SEAS and currently a postdoctoral fellow at MIT, and co-author of the study.
