Do Now - Darwin & Natural Selection

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.
