Q

What is the name of the principle that describes larger animals to have lower BMR, and smaller ones to have higher BMR relative to body size?

A

Jarman/Bell Principle; explains that larger animals require lower quality food and have lower BMR relative to smaller animals. Brains smaller in larger animals.

16
Q

Describe life histories of primates compared to other mammals, and primates in general.

A

Life histories of primates are allometrically long compared to other mammals of similar size. Otherwise, isometric within the primate order.
Exception - Gorilla

17
Q

As per life histories, what 6 characteristics do primates possess that contrast with other mammals?

A

Longer gestation length, postnatal development, first reproduction age, inter-birth interval, generation length and life span

18
Q

What is the difference between being precocial and altricial?

A

Precocial offspring are well developed at birth. Altricial are underdeveloped.

19
Q

What are the two hypotheses behind the development of stereoscopic vision?

A

Arboreal creatures required stereoscopic vision to gauge distance of tree branches.
Visual predation hypothesis pertains to insectivorous diets ancestral primates were thought to have. Easier to catch prey.
Theories not mutually exclusive.

20
Q

What is the difference between being monotypic and polytypic?

A

Monotypic has one species under its genus whereas polytypic has multiple species under its genus

21
Q

What is the difference between dental formulas of catarrhines and platyrrhines?

A

Catarrhines - 2.1.2.3

Platyrrhines - 2.1.3.3 - extra premolar

22
Q

What are the two most ancient primates?

A

Lorises and lemurs

23
Q

What is a trait found in two different species that evolved separately from one another?

A

Homeoplasy

24
Q

What is the name of a trait inherited from its last common ancestor?

A

Homology

25
Q

What is a molecular clock?

A

The estimated rate of mutations

26
Q

What (2) muscles do folivorous primates develop for chewing?

A

Temporalis and masseter

27
Q

How can we identify what primate is most likely folivorous or frugivorous?

A

Frugivorous -relatively larger incisors, flatter molars

Folivorous - relatively small incisors, larger, sharper molars

28
Q

What can body size tell us about primate ranging patterns?

A

Larger primates tend to have smaller day ranges, but larger home ranges. Opposite for smaller primates.

29
Q

What suborder of primates do not have patrilineal societies? What family of primates have male-biased dispersal into matrilineal groups?

A

Prosimians; Cercopithecines

30
Q

What 3 groups of primates have equal dispersal among genders?

A

Prosimians, callitrichids and colobines

31
Q

What two groups of primates have a 50/50 dispersal of equal dispersal and female-biased dispersal?

A

Hominoids and cebids
