Question

humans, monkeys, and other primates have more physical characteristics in common than they do with other mammals, like horses, dogs, or mice. these similarities are evidence for a more recent common ancestor among primates than between primates and other mammals. think about the face, teeth, hands or feet, and offspring of primates, like humans, and of other mammals you may have encountered. which of the following best describes contrasting physical characteristics between primates and other mammals?

female primates can give birth to a larger number of offspring at once than most other mammals.

other mammals have greater grasping ability than primates, since primates lack opposable thumbs.

the teeth of most primates are much larger in size than in other mammals.

primates have larger, forward-facing eyes and smaller noses than most other mammals.

Explanation:

Analyze the question prompt

The question asks for the statement that best describes contrasting physical characteristics between primates (such as humans) and other mammals (such as dogs, horses, or mice).

Evaluate the first option

The first option states that female primates give birth to a larger number of offspring at once. This is incorrect. Primates typically have smaller litter sizes (often just one offspring) and invest more time in parental care compared to many other mammals like mice or dogs.

Evaluate the second option

The second option states that other mammals have greater grasping ability because primates lack opposable thumbs. This is incorrect. Primates are characterized by having opposable thumbs/digits and excellent grasping (prehensile) abilities, which most other non-primate mammals lack.

Evaluate the third option

The third option states that the teeth of most primates are much larger in size than in other mammals. This is incorrect. Primate teeth are not generally larger than those of other mammals of comparable size, and primates typically have a generalized, reduced dentition compared to specialized carnivores or herbivores.

Evaluate the fourth option

The fourth option states that primates have larger, forward-facing eyes and smaller noses than most other mammals. This is correct. Evolutionary Anthropology shows that primates evolved a highly developed visual system with binocular, stereoscopic vision (forward-facing eyes) and a reduced reliance on olfaction (smaller noses/snouts) compared to many other mammalian lineages.

Select the correct option

The fourth option is the only biologically accurate contrast.

Answer:

• (A) Female primates can give birth to a larger number of offspring at once than most other mammals.
• (B) Other mammals have greater grasping ability than primates, since primates lack opposable thumbs.
• (C) The teeth of most primates are much larger in size than in other mammals.
• (D) Primates have larger, forward-facing eyes and smaller noses than most other mammals. (Correct answer)
