1

mammalia

the class to which all mammals belong; this includes placental, egg-laying, and marsupial mammals

2

quadrupedal

walking on all four limbs

3

prehensile

grasping

4

opposable

the thumb or big toe can make contact with the tip of each of the other digits on the same hand/foot

5

stereoscopic vision

characterized by overlapping fields of view, allowing humans and other primates to see in three dimensions

6

postorbital bar

the bony ring that separates the eye orbit from the back of the skull; within Primates, this feature is found among the prosimians

7

nocturnal

active during the night

8

olfactory

relating to the sense of smell

9

neocortex

the outer part of the brain that is involved in higher functions such as reasoning, abstract thought, and language

10

diurnal

active during the day

11

trichromatic

a condition in which an animal possesses three light-sensitive pigments in the cones in the retina of the eye, making it possible to see blue, green, and red

12

dichromatic

a condition in which an animal possesses two light-sensitive pigments in the cones in the retina of the eye, making it possible to see blue and green

13

estrus

period of sexual receptivity in females, correlated with ovulation

14

petrosal bulla

a bony outgrowth on the base of the skull that houses the three bones of the middle ear

20

K-selection strategy

a reproductive strategy in which females have few offspring and invest greater parental care in those offspring

21

arboreal hypothesis

the hypothesis that primate features evolved as adaptations to a life in the trees

22

visual predation hypothesis

the hypothesis ascribed to Matt Cartmill that primate features evolved as adaptations to insect predation

23

angiosperm radiation hypothesis

the hypothesis that primate features evolved as adaptations to flowering plants

24

narrow niche hypothesis

the hypothesis that the suite of characteristics seen in primates evolved not only from selection pressure for fine branch feeding, but also from the relaxation of previous selection pressures

25

Prosimii

the suborder that includes lemurs, lorises, and tarsiers

26

Anthropoidea

the suborder that includes monkeys, apes, and humans

27

Homininae

the taxonomic subfamily that includes modern humans and our earlier ancestors, as well as chimpanzees and bonobos

28

Strepsirhini

the suborder that comprises lemurs, lorises, and galagos

29

Haplorhini

the suborder that comprises tarsiers, monkeys, apes, and humans

30

home range

the entire area exploited by an animal or group of animals
