Darwin's Theory of Evolution

Which statement about the members of a population that live long enough to reproduce is consistent with the theory of evolution by natural selection?

• They transmit characteristics acquired by use and disuse to their offspring.

                

• They tend to produce fewer offspring than others in the population.

• They are the ones that are best adapted to survive in their environment.

• They will perpetuate unfavorable changes in the species.

How does natural selection drive evolution?

• It does not; natural selection and evolution are entirely separate processes

• Before they can reproduce, individuals must adapt certain traits through natural selection.

• Within a generation, natural selection causes populations to eliminate unfavorable traits.

• Over time, natural selection causes living populations to evolve environmental adaptations.
