Flashcards in Workman Reader Ch. 4 Deck (16):
1

comparative method

Comparing different
species in order to add to our knowledge of anatomy, physiology or behaviour

2

common ancestor

Where behavioural patterns are similar it may suggest
that the responses are ancient and might be traced back to a common ancestor

3

frugivorous

fruit-eating

4

mate
guarding.

following a female around and mating with her intermittently
during her fertile period, while simultaneously chasing off other potential subordinate suitors

5

provisioning
hypothesis

Although
the provisioning hypothesis combines elements of both earlier theories, it
is the hunting and meat-eating parts of the equation that it relies on most
heavily. It is certainly true that in today’s foraging societies, hunting is
largely a male preserve and the gathering of plant foods is largely a
female concern

6

hominids

early human-like ancestors

7

polygynous

where males have more than one
mate

8

male parental investment

long-lasting pair bonds with male partners who were
prepared to help provide for the offspring

9

cryptic oestrus

by concealing
their period of oestrus (which they call ‘cryptic oestrus’) women may have
made men attentive to them continually, since only in this way would males be
able to ensure that they father a partner’s offspring

10

sexual dimorphism

the degree to which the sexes differ
in physical characteristics

11

polyandry

where one female
monopolises a number of males

12

arbitrary culture theory

differences in chastity and in sexual permissiveness in general in terms of random differences between cultures, which
may suggest that it is free from evolutionary influences

13

sperm competition

those able to produce the largest quantities
of sperm are most likely to inseminate a female and thereby pass on their genes

14

resource extraction

female chimps and baboons will sometimes
exchange sex for food

15

sexy sons

may be of benefit if such women pass on these attractive features to their sons
who would then have improved chances of attracting women

16

developmental flexibility

allows humans to adjust to social and economic
circumstances
