Monogamy
M=F, no F swelling, medium testes, long coitus
24 of 68
Polygyny
M>>F, no F swelling, small testes, long coitus
25 of 68
Polygynandry
M>F, F selling, large testes, short coitus
26 of 68
Polyandry
F>M, some F swelling, large testes, short coitus
27 of 68
F swelling
incites M-M competition
28 of 68
Large testes occur because
Multiple males, so sperm competition
29 of 68
short coitus
when there are other males
30 of 68
cyptic females choice
selection of sperm after copulation
31 of 68

purpose of gibbon singing

36 of 68
Dispersed females
solitary F or grouped F with de-synchronised ferility
37 of 68
Clumped Females
grouped F with synchronised fetility
38 of 68
Dispersed F
M can monopolise
39 of 68
F always dicate grouping
false: PTM, infanticide
40 of 68
PTM likely when
defendable resource, differing territory quality
41 of 68
Resource defense model
F live in groups because: Br increases with group size as get more food, because better at defending food from other groups
42 of 68
Predator defense model
F live in groups because: increased group size means better able to defende against predators so BR increases
43 of 68
Resource defense model
Wrangham et al., 1979
44 of 68
critisims of resource defense model
in large groups intragroup competition for food will outweight intergroup competition
45 of 68
critisisms of predator defense model
nothing counteracts intra group competition, only has a positive effect if lifetime RS is used
46 of 68
dunbar, 1988
predator risk sets the lower limit, intra groups food comp sets upp limit
47 of 68
scramble competition
food is dispersed so no-one can monopolise it
48 of 68
contest competition
food is clumped so winner gets greater share
49 of 68
BCG and WGS
larger group gets more food as dominant
50 of 68
BGC and WGC
PF depends on group size and dominance
51 of 68
gorillas only
north of congo river
52 of 68
Why do gorillas have a small penis
most competition pre coitus, big genitals are an imposition
53 of 68
incestusous sex occurs when?
overalpping generations, sons take over fathers position
54 of 68

63 of 68
why do chimps have very fast coitus
live in multi male groups, lots of competition
64 of 68

why did humans not have Resource holding polygyny
Hard in Hunter gathered societies
