Evolution Test Review

What

type

of structure?

• Homologous

• Analogous

• Embryological

• Vestigial

The similarities of bone structure in the diagram provide evidence of what?

• The organisms probably use there forelimbs for the same thing.

• The organisms evolved from a common ancestor.

• The organisms have the same DNA.

• All vertebrate species have identical forelimbs.

Scientists have found evidence that about 2.4 million years ago a gene regulating jaw muscles mutated and may have led to the more graceful human jaw we see today. The diagram below shows the skulls of 3 hominid species. Which statement below most closely explains the link between jaw size and hominid evolution?

• The jaws of hominids evolved to be smaller and less protruding over time as did the skull.

• The jaws of hominids evolved to be larger and more protruding over time.

• There appears to be no change in the jaws of hominids over time.

• The jaws of hominids changed over time due to a change in brain size

Which of the following correctly summarizes the physical changes that early humans went through over the past million years or so?

• Brain size increased as jaw size decreased
• Brain size decreased as jaw size increased
• Bipedalism increased as use of tools increased
• Bipedalism decreased as the use of tools increased

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 image represents which process?

• founder effect

• bottleneck effect

• gene flow
