Paternity Uncertainty Hypothesis
Introduction. Paternity uncertainty hypothesis is a construct in behavioral ecology and evolutionary psychology, used to explain differential investment in offspring between the sexes. The hypothesis states that due to the nature of internal fertilization, a male inseminator cannot be fully assured (consciously or otherwise) of the genetic ...

Paternity Uncertainty and Father-Offspring Conflict
The sex-based asymmetry in parental certainty contributes to a variety of conflicts between males and females and to conflicts between males and putative offspring (Trivers 1974 ). Specifically, a male may come in conflict with offspring as he and the child attempt to further their own genetic success. As said, a male who is uncertain that the ...

Paternity Uncertainty and Evolutionary Psychology: How a Seemingly
According to evolutionary psychologists, paternity uncertainty arises from the fact that men are `hard wired' to seek as many sexual partners as they can, and women to seek men of superior genetic quality. This account is said to be demonstrable through independent biological evidence of widespread discrepancy between putative and actual ...
Paternity Uncertainty and Evolutionary Psychology: How a Seemingly
Evolutionary psychologists aspire to show how —contrary to `soft' social sciences such as sociology — `seemingly capricious' occurrences in the realm of human behaviour follow biologistic `laws of greater generality' (Pinker, 2005: xii).This article is a case study of the `seemingly capricious occurrence' of paternity uncertainty. According to evolutionary psychologists, paternity ...

Paternity uncertainty and the complex repertoire of human mating
The use of the paternity hypothesis as an explanatory framework encourages dualistic thinking because it focuses on differences in reproductive strategies and uses a single biological variable, paternity certainty. ences presented by Buss could also be explained by the subordination of women in patriarchal culture, rather than as a result of differences in evolutionary adaptation. Although ...
Paternity Uncertainty Hypothesis
Paternity uncertainty hypothesis is a construct in behavioral ecology and evolutionary psychology, used to explain differential investment in off-spring between the sexes. The hypothesis states that due to the nature of internal fertilization, a male inseminator cannot be fully assured (consciously or otherwise) of the genetic identity
Reevaluating the grandmother hypothesis
Incorporating paternity uncertainty into the model demonstrates the conditions under which the grandmother hypothesis is more plausible than a hypothesis that focuses on the contributions of men. Keywords: Grandmother hypothesis; Human evolution; Menopause; Paternity uncertainty.

Alternatively, the paternity uncertainty hypothesis for differential grandparent care brings about a different set of predictions. A grandfather, for example, has two degrees of uncertainty to his son's children but only one to his daughter's children. ...

Family Violence: How Paternity Uncertainty Raises the Stakes
We discuss how intimate partner violence (IPV), motivated by paternity uncertainty, sometimes leads to uxoricide (wife killing) by exploring two contrasting evolutionary ideas: the slip-up hypothesis (Daly & Wilson, 1988) and homicide adaptation theory (Buss & Duntley, 1998), and we apply evolutionary game theory in an attempt to better ...
Evolutionary psychology of parenting
Evolutionary psychology of parenting. Due to not carrying the child, the male is suggested to experience paternal uncertainty. [1] Different parenting styles across cultures also influence the temperament of an offspring. Additionally, varying attachment styles can influence the development of an offspring, impacting their future choices on ...

putative offspring (Trivers 1974). Speci cally, a. and the child attempt to further their own genetic success. As said, a male who is uncertain that the offspring shares his genes stands more to gain genetically by reducing investment in the child and increasing investment in mating and repro-duction.
Why men invest in non-biological offspring: paternal care and paternity
However, low paternity confidence was reported for only 49 of 3066 pregnancies (1.46%), and in another 3% of pregnancies, men refused to answer questions about paternity. Teasing out the effects of paternity uncertainty on paternal investments and paternal care may be more fruitful in societies where extra-pair paternity is more common.
Paternity Un(certainty): How the Law Surrounding Paternity Challenges
paternity fraud or paternity uncertainty is a central issue in Karen Shepard's 2013 historical novel, The Celestials, 8 . about Chinese strikebreakers who came to work in a shoe factory in North Adams, Massachusetts in the late 1800s. The factory owner's wife has an affair with the Chinese foreman, which results in the birth of ...
Paternity Certainty
However, in some species of socially monogamic passerine birds, extra-pair paternity is a common feature, and investment in non-kin brood is also common. Even with experimental manipulations of the degree of uncertainty of paternity, these males expend the same amount of investment in paternal care towards the offspring (Kempenaers et al. 1998).
The expendable male hypothesis
Paternity uncertainty represents the oldest and most common explanation of matrilineal inheritance and cooperative behaviour. Alexander was the first evolutionary anthropologist to describe what is, in fact, 'one of the oldest hypotheses in social science' in evolutionary terms. The adage, 'Mommy's baby; Daddy's, maybe' captures the ...
