Evolution: Natural Selection

Individuals that are well adapted to their environment will survive and produce:

• Fewer mutations

• Stronger genes

• More offspring

• Better traits

You look at two species and see very similar DNA. What does this likely tell you?

• These are the same animal.
• These animals have a common ancestor.
• These animals are not likely related.
• These animals are likely becoming one species.

According to the theory of natural selection, some individuals more likely than others to survive and reproduce because they:

• pass on to their offspring their newly acquired traits.
• are better adapted to their environment than others and will pass on those adaptations to future offspring.
• do not pass on newly acquired traits.
• produce fewer offspring than others in the same environment.
