Question 2

Explain the taxonomic problems associated with members of Tarsiiformes. How would an evolutionary taxonomist classify these organisms within the order Primate? How would a cladist classify these organisms within the primates?

Question 3

A typical day in the life of a primate

Accepted Answer

Primates typically have a routine that includes two main feeding periods, one in the morning and another in the late afternoon, to optimize energy intake and digestion.

Question 4

Cercopithecines

Accepted Answer

Cercopithecines typically live in groups where all the females are related. This is known as a matrilineal social structure. Male offspring leave the group at maturity and join other groups.

Question 5

Compare and contrast five differences in morphology and behavior between the strepsirrhine primates and the haplorrhine primates. Make a distinction between ancestral and derived traits in your discussion.

Question 6

Which of the following contributes to the endangerment of primates?

Accepted Answer

Habitat destruction is a major factor contributing to the endangerment of primates as it leads to loss of their natural living spaces.

Question 9

Using the information from the chapter on how ecology shapes behavior, create a model showing how certain ecological pressures might have favored sociality in primates.

Accepted Answer

Question 10

How do active metabolism, growth rate, and reproductive effort affect basal metabolism?

Accepted Answer

Question 11

Imagine you discover a new species of primate. It has a large body size (about 35 lbs.), is sexually dimorphic, appears to spend much of its time in the trees, lives in dense tropical forest, and has longer arms than legs. Based on this information only, what can you hypothesize about this new species' behavior and ecology?

Accepted Answer

The answer of Imagine you discover a new species of...

Question 12

The size and composition of primate social groups are a compromise between

Accepted Answer

The size and composition of primate social groups are a balance between the costs and benefits of sociality. Sociality can provide individuals with benefits such as increased protection from predators, assistance with food acquisition, and greater reproductive opportunities. However, sociality also involves costs like increased competition for resources and increased risk of disease transmission. Primate social groups are therefore typically composed of a balance of individuals that maximizes the benefits of sociality while minimizing the costs.

Question 13

Which of the following contributes to the endangerment of primates?

Accepted Answer

Biomedical research often involves capturing primates from the wild, which can contribute to their population decline and endangerment.

Question 14

If primates make different calls when they detect other species nearby, then one could predict

Accepted Answer

Different calls in response to other species nearby are typically alarm calls used to warn others of potential predation. This allows individuals to respond appropriately and avoid becoming prey.

Question 15

Summarize the changes in manual dexterity and sensory reorganization that accompanied the evolution of primates.

Accepted Answer

The answer of Summarize the changes in manual dexterity and...

Question 16

The United States has

Accepted Answer

The correct answer is B, as the United States has decreased the number of imported primates in recent decades. This is due to the implementation of the Animal Welfare Act, which includes regulations on the care and use of non-human primates in research. Furthermore, there has been a shift towards using domestically bred primates rather than importing them from other countries.

Question 17

Compare and contrast how primates differ from other mammals in each of the following categories and give a specific example for each one: (a) limbs and locomotion, (b) teeth and diet, (c) the senses, (d) the brain and intelligence, and (e) behavior.

Accepted Answer

The answer of Compare and contrast how primates differ from...

Question 18

What adaptations do some plants have to make themselves less palatable to animals that might otherwise eat them? Explain the primate counteradaptations that allow them to eat such plants.

Accepted Answer

The answer of What adaptations do some plants have to...
