Which of the following best describes the phrase "survival of the fittest"?
Individuals that can live the longest are the most successful.
Individuals that are the strongest in a population are the most successful.
Individuals that can survive and reproduce are the most successful.
Individuals that are the fastest in a population are the most successful.
Why is the mouse population changing over time?
The light mice can reproduce more successfully than the dark mice
The hawks eat more dark mice than light mice because the dark mice taste better
The hawks eat more light mice than dark mice because they can see the light mice more easily
The hawks eat more dark mice than light mice because they can see the dark mice more easily
The trees these moths used to live on were white, but have been covered in soot from coal factories. Which moth will be more successful in this environment?
Dark moth
Light moth
Both will be equally successful
Neither will be successful
Why are advantageous traits more likely to be passed onto offspring?
Because they are more likely to survive and reproduce.
Because they come from dominant alleles.
Because they come from recessive alleles.
Because the organism knew it needed that trait, survives, and passes it on.
Sometimes bones in the front limbs of animals are very similar in structure. What do we call similar bone structures that indicate a link to a common ancestor?
Adaptations
Gradualism
Homologous Structures
Extinction
