Evolution Evidence and Mechanisms

A few deer wander out of their native woods into a completely new park where no deer had ever been before. They go on to create an entirely new population.

• Genetic Drift

• Natural Selection

• Non-random mating

• Mutation

Which of the following is true?

• Gene pool frequencies do not change as a result of migration in or out of a population.

• Gene flow occurs only as a result of isolation of a small population.

• Gene flow can cause new alleles to enter a population's gene pool.

• Gene flow is due the the selection of the most favorable traits.

The opossum and kangaroo both incubate their young in a pouch. This provides evidence that they---

• are descended from a common ancestor

• Have very similar skeletal structures

• belong to the same species

• must range great distances to eat

Why is the mouse population changing over time?

• The light mice can reproduce more successfully than the dark mice

• The hawks eat more dark mice than light mice because the dark mice taste better

• The hawks eat more light mice than dark mice because they can see the light mice more easily

• The hawks eat more dark mice than light mice because they can see the dark mice more easily

Which of the following is NOT part of the that mechanisms of natural selection?

• Organisms produce more offspring than can survive.

• Disease and natural disaster will limit population growth.

• Species today descended with modifications from ancestral species.

• Organisms with advantages will survive and reproduce.

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

A population of salamanders, 50% of whom were spotted, decreased from 500 to only 100 in just a few months when a drought dried up much of the lake they inhabit. The remaining population had a much higher frequency of spotted than non-spotted salamanders compared with the original population. The most likely cause for this change is -- 

• Natural Selection

• Gene Flow

• Mutation

• Genetic Drift
