7 Wild Mustangs were taken from the prairies of Iowa after a Texan Rancher purchased them and provided them with their own pasture. Those 7 Mustangs eventually became 122.

Bats are common in Texas, especially in rocky regions. Bats with longer hang claws have demonstrated higher fitness because of their ability to cling to rock while resting. This adaptation is becoming more frequent in the population. What mechanism of evolution is this?

• Natural Selection

• Non-random mating

• Gene Flow

• Genetic Drift

According to the theory of natural selection, why are some individuals more likely than others to survive and reproduce?

• Some individuals pass on to their offspring new characteristics they have acquired during their lifetimes.

• Some individuals are better adapted to exist in their environment than others are.

• Some individuals do not pass on to their offspring new characteristics they have acquired during their lifetimes.

• Some individuals tend to produce fewer offspring than others in the same environment.

Mutations are important because they bring about

• death of the organism in which they develop

• genetic variation needed for a population to evolve

• benefits for the individual, not for the population

• Hardey-Weinberg equilibrium within a population
