- 6.1: Ecology
- If you’ve ever seen a female monkey cooing over her newborn baby or watched a tufted capuchin monkey use rocks as a hammer and anvil to crack open a nut, then you know how interesting nonhuman primates can be. As our closest living relatives, their behavior is strikingly similar to our own. Primatology studies primate behavior. Biological anthropologists studying primates are interested in their social complexity and ecological and behavioral variation.
- 6.2: Sociality, Residency Patterns, and Dispersal
- The majority of mammal species are solitary, with individuals living alone, except for mothers and dependent offspring. However, most primate species live in groups. Primate groups vary in size, composition, and cohesiveness. In this section, we’ll examine why primates live in groups and who stays, who goes, and why.
- 6.3: Reproductive Strategies
- It is important to recognize that primate reproductive strategies have evolved to maximize individual reproductive success. These strategies are divided into those dealing with offspring production and care and those that maximize mating success. Female strategies focus on obtaining the food necessary to sustain a pregnancy and choosing the best male(s) to father offspring. Male strategies focus on obtaining access to receptive females.
- 6.4: Communication
- In its most basic form, communication occurs when one individual (the sender) emits a signal that conveys information, which is detected by another individual. Primate communication comes in four forms: vocal, visual, olfactory, and tactile. Species vary in their reliance on each.
- 6.5: The Question of Future
- It may be surprising in a chapter on nonhuman primates to see a discussion of culture. After all, culture is considered by many, including cultural anthropologists, to be a distinguishing characteristic of humans. Indeed, some anthropologists question claims of culture in primates and other animals. Definitions of animal culture focus on specific behaviors that are unique to one population.
