Evolution Quiz

Charles Darwin was best known in the 19th century for:

• creating the idea of evolution

• creating the idea of uniformitarianism

• making the idea of evolution acceptable for scientists and the educated general public

• all of the above

Charles Darwin concluded that the 13 species of finches on the Galápagos Islands:

• were identical to 13 finch species in northwestern South America 600 miles to the east

• probably evolved from one ancestral South American species

• had all adapted to the same food sources

• All of the above

Through careful observation, Charles Darwin came to understand that:

• populations of plants and animals in nature most often consist of individuals that are clones of each other

• those individuals whose variation gives them an advantage in staying alive long enough to reproduce are more likely to pass their traits on to the next generation

• populations of a species that become isolated from others by adapting to different environmental niches quickly become extinct

• all of the above
