1

Comparative Primatology

the study of our closest living relatives, the primates, for the purpose of understanding aspects of our own behavior

2

Strepsirrhini

Primate suborder that includes the Lemurs, Lorises, and Galapagos (the prosimians)

3

Haplorrhini

Primate suborder that includes the Tarsiers, monkeys, apes, and humans

4

Ceboidea

Primate superfamily that includes all monkeys found in the Americas

5

Cercopithecoidea

Primate superfamily that includes all monkeys found in Africa and Asia

6

Anthropoids

all monkeys, apes, and humans

7

Hominoid

Member of the super-family Hominoidea

8

Hominin

the division in Hominoidea that includes humans and our recent ancestors

9

Behavorial Ecology

The study of behavior from ecological and evolutionary perspectives

10

Foraging

the act of seeking and processing food

11

Five Areas of Socioecological Pressure

Foraging/Nutrition, Predation, Intraspecific competition, Interspecific competition, Habitat locomotion

12

Strategy

Set of behavior patterns that has become prominent in a population as a result of natural selection

13

Kin Selection

Behavorial favoring of one's close genetic relatives

14

Altruism

Selflessness in one's behavior

15

Potential

The spectrum of possible expression created by morphology, evolutionary history, and other aspects of a genotype

16

Performance

the actual expression of a trait or behavior; the actual influence on a phenotype a trait has

17

Phylogenetic Contraints

limits on current behavior or traits due to patterns and trends in an organism's evolutionary past

18

Infant Dependency Period

Period during which the infant is wholly reliant on others for nutrition, movement, thermoregulation, and protection

19

Spandrels

The by-products of structural change

20

Home Range

Area used by a primate group or community; often overlap between individuals

21

Affiliative

Bond enhancing or prosocial

22

Agonistic

Aggressive or combative

23

Philopatric

Staying in one's natal group; the habitually to stay or return to a particular area

24

Estrus

Behavorial and physiological sexual receptivity

25

Sociosocial Behavior

Nonreproductive sexual behavior that serves to resolve conflicts and/or reinforce alliances and coalitions

26

Primate-wide Features

-Five digits on hand and feet and free mobility of limbs
-flexible, grasping digits, with sensitive friction pads and nails rather than claws
-Erect posture in many groups

27

Two Major Groups of Haplorhines:

Tarsiers and Anthropoids (New World and Old Monkeys)

28

Platyrrhines

New World monkeys with outward facing nostrils

29

Catarrhines

Old World Monkeys and Hominoids (Apes and Humans)

30

Terrestrial Primates

Primates that live predominantly or entirely on land
-generally live in larger groups than arboreal species
-face greater danger from predators
-have large group size that provides some protection against predation
