Bactrian camels, dromedaries, llamas, and alpacas are all members of the same taxonomic family, Camelidae. Members of this family all have two toes, no hooves, true canine teeth, and a split upper lip. The family Camelidae originated in North America. The physical features of animals in this family and the family's geographical origin provide evidence that all these animals --

• live in the same type of ecosystem.

• have slowly evolved to become herbivores.

• have a common ancestor

• exchanged DNA at some point in the past

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 this population. What mechanism of evolution is this?

• Natural Selection

• Gene Flow

• Non-random mating

• Genetic Drift

Cetaceans are a taxonomic group including whales and their relatives.

Which statement provides the best evidence that Ambulocetus natans is an ancestor of Basilosaurus isis?
