It has been recognized since the 1800s that differences in available prey can drive natural selection and local genetic adaptation, such as the classic case of Darwin’s finches, in which selection is driven by variation in the size and type of available seeds and other food sources (Grant & Grant 2003). in a paddle called the telson.
