1
95-97% of mammals show -- paternal investment
little
2
chimps and bonobos show no paternal investment though some -- is probable in chimps
paternal kin recognition
3
predictors of paternal care: -- paternity certainty
high
4
predictors of paternal care: -- benefits to offspring survival
high
5
predictors of paternal care: -- opportunity costs
low
6
-- paternity means investing in offspring you aren't genetically related to which is considered wasteful from the fitness perspective
misattributing
7
men should be more willing to invest when their investment --
matters
8
investment is less -- if it interferes less, or even coincides with future mating opportunities
costly
9
men's investment should be tempered by their probability of --
paternity
10
-- paternal confidence leads to less investment
lower
11
Strategy A: If infants looks more -- they may garner investment if the social father is not the biological father
anonymous
12
Strategy B: If infants -- father it might garner more investment by signaling paternity certainty
resembles
13
videotapes of mothers and their families after birth show that they allege -- resemblance
paternal
14
Anderson: men with higher paternity confidence should have -- actual paternity
higher
15
Do men alter their investments according to their paternity certainty? -- reports of investment dominate this literature and are therefore not very reliable
self
16
one clear comparison of investment and paternity comes from looking at --
fathers and stepfathers
17
genetic offspring of current mate
mating and parenting effort
18
genetic offspring of previous mate
parenting effort
19
step-offpring of current mate
mating effort
20
step-offspring of previous mate
neither mating or parenting effort
21
amount of money spent on children is highest for
genetic children of current mate
22
T/F: amount of money spent on genetic children of previous mate and stepchildren of current mate is about the same
true
23
time involvement with children is highest for
genetic children of current mate
24
T/F: time involvement with stepchildren of current mate is higher than that with genetic children of previous mate
true
25
-- resemblance is one potential cue of paternity (Apicella and Marlowe)
physical
26
men react more -- toward fictitious offspring whose faces were morphed to look more like their own
favorably
27
another cue to paternity is the perception of partner --
fidelity
28
men currently in a relationship with their child's mother report significantly -- investment than those no longer with the mother
more
29
Alvergne et al: raters were able to guess the true father with significant accuracy using facial cues but not
olfactory cues
