acquired characteristics
survival of the fittest
According to Darwin’s theory of natural selection, the individuals that tend to survive are those that have
characteristics their parents acquired by use and disuse.
the greatest number of offspring.
characteristics that plant and animal breeders value.
variations best suited to the environment.
