Cuckoldry Biology

Cuckoldry Biology. Evolutionary biology theory predicts that males usually won’t invest a lot of time raising offspring when there is a good chance they are not the fathers. When being a cuckold makes evolutionary sense.

But the reality of the bird world is much less ideal.

Evolutionary biology theory predicts that males usually won’t invest a lot of time raising offspring when there is a good chance they are not the fathers. Yale university researchers have found a notable exception to this premise—a male fish in the mediterranean, the ocellated wrasse, that is more likely to be paternal when there is grave doubt about the offsprings’. An urban myth, often asserted with a wink & a nod in some circles, is that a very high proportion of children in western countries are not raised by their biological father, and in fact are not aware that their putative biological father is not. Under these circumstances, selection is expected to favour males that reduce paternal effort in response to cuckoldry.

Rate of cuckolded fathers stayed low in the past across human societies.

Under these circumstances, selection is expected to favour males that reduce paternal effort in response to cuckoldry. Genetic approaches are now developed to estimate historical cuckoldry rates.

Specifically, we show that cuckolded males only reduce paternal investment if both the costs of caring are relatively high and there is a high risk of cuckoldry.

In many species, however, these conditions are not satisfied and. In one notable instance, the term ‘cuckold’ has been used to mean the agent of cuckoldry rather than its victim. By forcing women to signal their menses, male relatives who may be affected by a woman's infidelities are able to assist her husband with paternity assessments.

Cuckoldry is detrimental in the dogon as land is inherited patrilineally, meaning that resources can be misdirected into genetically unrelated lineages.

Although the concept of ‘cuckoldry’ is now widely employed in behavioural biology, little attention has been paid to its origins and associations in ordinary discourse.
