Which of the following is a key principle of Kleiber's Law in relation to primate metabolism?
Larger animals are more energy-efficient and require less energy per unit of body mass.
What is the primary function of social behavior among primates?
To mediate cooperation among competitors for survival and reproduction.
Which primate group is characterized by strict seasonal breeding, with some species breeding only once per year?
Lemurs
What does the Resource Defense Hypothesis primarily suggest about female primates?
They are driven to group living to defend food resources collaboratively.
How do larger primate species typically manage the need for large amounts of food?
By consuming more abundant but lower-quality foods like leaves.
Which of the following is a behavioral specialization related to food acquisition in primates?
Dexterity and tool use
What is the primary cost of group living among primates?
Increased competition for food
Which metabolic principle explains why small primates require more energy per gram of body mass than large primates?
MSMR (Mass-Specific Metabolic Rate)
What is a key characteristic of primate sociality?
All primates are social, but not all are gregarious.
Which of the following best describes the Jarman-Bell Principle?
Larger animals can afford to eat low-quality, abundant foods.
What principle underlies kin selection as a driver of cooperation among primates?
Altruistic behaviors increase when individuals share genes.
Reciprocal altruism in primates is most likely to occur when
There is a high frequency of social interactions with memory and trust.
Which of the following is a benefit of non-kin cooperation among primates?
Increased reproductive success
What is the primary advantage of multilevel selection in primate social structures?
Balances selection at both individual and group levels.
What role does grooming play in primate social structures?
Reinforces social bonds and alliances
Which of the following is a key concept in understanding primate cooperation?
Reciprocal altruism
How does multilevel selection benefit cooperative groups?
It allows cooperative groups to outperform selfish ones.
What type of social bond is most likely to promote long-term cooperation?
Kin-based bond
In primates, what typically drives male dispersal from natal groups?
Mate competition

In primate societies, which behavior most commonly establishes social bonds?
Grooming
What is the function of sacculated stomachs in primates?

What characteristic is typical of female philopatry in primates?
Females remain in their natal groups
Which social structure is characterized by multiple males and females living together?
Multi-male/multi-female group
Which primate is known for using tools to crack nuts?
Capuchins
Which principle predicts that larger animals are more energy-efficient than smaller ones?
