Natural Selection Review

"Survival of the Fittest" describes which theory

• a) natural selection
• b) gravity
• c) heredity
• d) string theory

Modern whales developed their traits through natural selection.  What occurs during the process of natural selection?

• Organisms choose mates from other species to create new species
• Breeders selectively cross organisms with desired traits
• Only the fittest organisms can survive and reproduce
• Organisms remain exactly the same over time.

The example of the peppered (brown) moths living near English industrial cities demonstrates that

• A change in an environment can result in the evolution of species living there
• Evolution occurs so slowly that is it not possible to determine that it has happened in less than a million years
• The environment near these cities has always favored dark colored moths

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 trait is an acquired phenotype.

The difference in the physical traits of an individual from those of other individuals in a group is called a(n)

• change
• adaption
• species
• variation

The ability of an organism to survive and reproduce is known as...

• Adaptation
• Trait
• Fitness
• Variation

Any variation that can help a species survive in a given environment is called...

• an adapatation
• a characteristic
• a homologous structure
• a vestigial structure

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

These moths are all the same species. The differences between their wings is an example of ________________

• Natural Selection
• Variation
• Homeostasis
• Extinction

The change over time in populations of related species.

• biological evolution
• transition
• variation
• adaptation
