Lamarck’s ideas about evolution include the concept that differences among the traits of organisms arise

    as a result of

• continual increases in population size.

                

       

            

• the actions of organisms as they use or fail to use body structures.

• an unchanging local environment.

• the natural variations already present within the population of organisms.

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.
