Final answer:
True, Darwin studied artificial selection by breeders and applied this knowledge to develop his theory of natural selection.
Step-by-step explanation:
The statement is true: To find an explanation for changes in nature, Charles Darwin studied changes produced by plant and animal breeders. Darwin's studies on artificial selection—the selective breeding of animals and plants by humans to produce desired traits—significantly influenced his development of the theory of natural selection. By observing how breeders could select traits, he inferred that in nature, a similar process occurred, which he termed natural selection. In nature, those organisms with favorable variations, or traits, that increased their survival and ability to reproduce would pass on those traits, leading to evolutionary changes over time.
