When Charles Darwin visited the Galápagos Islands in the 1800’s, he observed many types of organisms that were similar but lived on different islands. The four species of mockingbirds found on the
Galápagos Islands are shown below. Each species lives on a different island.

The children of light colored moths were born darker.
Light colored moths became more aggressive in fighting predators.
Dark colored moths had a better chance of surviving to produce dark-colored offspring, and dark
moths became more abundant.
Plant breeding has been used for thousands of years, as a way to provide for humans. It began with the domestication of wild maize (corn) shown below. This is an example of--
