Which of the following is an example of disruptive selection?

• Individuals at both extremes of a trait are favored

• Only the average trait is favored

• Selection favors one extreme trait

• No changes occur in the population

Analogous structures arise due to:

• Common ancestry

• Similar environmental pressures

• Genetic drift

• Fossilization

The term "population" in biology refers to:

• A group of individuals of the same species living in an area

• A diagram of evolutionary relationships

• The total number of fossils discovered

• Any living organism

Which statement best describes homologous structures?

• They indicate a common ancestor

• They perform the same function in all organisms

• They are found only in extinct species

• They arise due to genetic drift
