Evolution

What is the primary mechanism that drives evolution?

• Mutation

• Artificial selection

• Natural selection

• Gene duplication

What is speciation?

• The creation of a new species from an existing species.

• The extinction of a species.

• The merging of two species into one species.

• The adaptation of a species to a new environment.

What is phylogenetics?

• The study of the evolutionary relationships between species.

• The study of the genetic makeup of species.

• The study of the behavior of species.

• The study of the physical characteristics of species.

What is the Hardy-Weinberg principle?

• The principle that evolution only occurs in populations that are large enough to maintain genetic diversity.

• The principle that evolution is a slow and gradual process.

• The principle that populations will remain in genetic equilibrium if certain conditions are met.

• The principle that evolution only occurs in populations that are isolated from one another.

What is the role of mutation in evolution?

• To create new traits that can be selected for or against.

• To increase the genetic diversity of a population.

• To decrease the genetic diversity of a population.

• To prevent evolution from occurring.

What is natural selection?

• The process by which individuals with favorable traits are more likely to survive and reproduce.

• The process by which individuals with unfavorable traits are more likely to survive and reproduce.

• The process by which individuals with random traits are more likely to survive and reproduce.

• The process by which individuals with identical traits are more likely to survive and reproduce.

How does the environment affect natural selection?

• By causing the extinction of species that are not adapted to the environment.

• By causing the extinction of species that are adapted to the environment.

• By promoting the survival and reproduction of species that are adapted to the environment.

• By promoting the survival and reproduction of species that are not adapted to the environment.

How do new species arise through speciation?

• Through mutation and natural selection.

• Through genetic drift and artificial selection.

• Through hybridization and genetic recombination.

• Through genetic drift and genetic recombination.

How does genetic drift affect the genetic diversity of a population?

• By causing the loss of genetic diversity in small populations.

• By causing the increase of genetic diversity in large population.

• By having no effect on the genetic diversity of populations.

• By causing the increase of genetic diversity of small populations.

What is the role of genetic variation in evolution?

• To provide the raw material for natural selection to act on.

• To prevent evolution from occurring.

• To cause the extinction of species.

• To have no effect on evolution.
