The common cactus finch has a pointed beak adapted to feed on cactus, whereas the medium ground finch has a blunt beak adapted to crush seeds. "They just sort of run into each other," says Rosemary.

She first shows them the short film the beak of the finch, which describes research by biologists peter and rosemary grant on the galpagos finches. They are known for their work with Darwin's finches on Daphne Major, one of the Galpagos Islands. This explain why genes on the Z chromosome cannot flow from the medium ground finch to the cactus finch via these hybrid females, whereas genes in other parts of the genome can, because parents of the hybrid contribute equally.

The cactus finch (Geospiza scandens) is slightly larger than the medium ground finch (G. fortis), has a more pointed beak and is specialized to feed on cactus. Where the struggle for existence is fierce, the caltrop that is likeliest to succeed is the plant that puts more energy into spines and less into seeds; but in the safer, more secluded spot, the fittest plants are the ones that put more energy into making seeds and less energy into protecting them. The Grants travelled to the Tres Marias Islands off Mexico to conduct field studies of the birds that inhabited the island. Microevolution due to natural selection observed directly.

For the next year, she studied genetics under Conrad Waddington and later devised a dissertation to study isolated populations of fish. Where there are many finches, each mericarp has fewer seeds, but it has longer and more numerous spines. Thus, evolutionary success is based on individual selection within a single generation.
