The human gene for muscle protein differs from the muscle protein in monkeys in 4 places. It differs from chickens in 25 places. According to this information, which organism is more closely related to humans?

• Monkeys are more closely related because their proteins have fewer differences.

• Chickens are closer to humans because there are more genes.

• Monkeys are closer to humans because they both have the exact same genes.

• Neither organism is related to humans.

Charles Darwin traveled to the Galapagos Islands and studied a variety of species including tortoises, finches, and mockingbirds. Which type of evidence was he NOT able to use to form and support his theory?

Structures are similar in function but not in anatomical structure

• Vestigial

• Homologous

• Analogous Structures

• Embryonic

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

Based on the illustration to the right, what do the similarities between human and chimpanzee hands and feet suggest about the different organisms?

• Chimpanzees and humans both have hands and feet adapted for walking upright, showing they have identical DNA.

• Chimpanzees and humans both have similar hands for grasping, proving they make and use complex tools.

• Humans and chimpanzees both developed five digits on their hands and feet, suggesting they have a common ancestor.

• Humans and chimpanzees both have thumbs, proving they eat similar foods like meat, nuts, and vegetation.
