• Mutation

• Genetic drift

• Natural selection

• Gene flow

Natural Selection

Which of the following is the correct definition of natural selection?

• The idea that organisms less equipped for their environment tend to survive longer

• The idea that organisms more well equipped for their environment tend to survive longer

• The idea that organisms more well equipped for their environment tend to not survive

• None.

Natural Selection

Which best describes the phrase survival of the fittest?

• strongest in a population are most successful

• fastest in a population are most successful

• those that can survive and reproduce are most successful

• those that can live the longest are most successful

Natural Selection

Where do adaptations come from?

• The individual organism decides to adapt

• Mutations that give an organism an advantage in its environment

• Genetic recombination during meiosis

• Both mutations and genetic recombination are sources of adaptation

• ability to survive cold weather

• hunting skills

• all of the above

• genes.
• variations.
• traits.
• theories.

What is most likely to happen to moth populations in the picture shown?

• Light moths--hunted easily, dark moths--population increase

• Dark moths--hunted easily, dark moths--population increase

• Light moths--hunted easily, light moths--population increase

• Lights moths will change their color to match dark moths.

Principles of Evolution

Speciation can occur as a result of geographic isolation because _________.

• members of a species can no longer find mates

• populations that live in different environments may be exposed to different selection pressures

• exchange of genes during recombination

• movement of genes within a population because of interbreeding
