• True

• False

• True

• False

• Lamarck

• Darwin

• Malthus

• Lyell

If people choose certain animals to breed because of some desirable traits, this is called _________________.

• farming

• artificial selection

• natural selection

• survival of the fittest

The statement "improving the intelligence of an adult through education will result in that adult's descendants being born with greater intelligence" is an example of:

• Darwinism

• Lamarckism

You hear a student say, "The giraffe stretched its neck to reach for the higher leaves; its offspring would inherit a longer neck as a result." You would correct them by saying:

• tell someone who cares

• characteristics acquired during an organism's life are NOT passed down through its genes

• you are correct

Evolution is _______________________.

• the study of how things change over time

• how organisms can pass traits acquired during their lifetime to their offspring

• the breeding of domesticated plants and animals for specific traits

• survival of the fittest

Individuals evolve of time, NOT populations.

• True

• False

A bear may produce more cubs than can survive due to struggle for survival. This statement exemplifies Darwin's principle of __________________.

• overproduction

• variation

• adaptation

• descent with modification
