Female Infidelity and Paternal Uncertainty

Evolutionary Perspectives on Male Anti-####oldry Tactics

In most cultures, marriage vows entail the promise of fidelity and lifelong commitment. In principle, marriage vows are a contract – a reproductive contract – between two individuals to maintain both emotional and sexual fidelity to one another ‘til death do them part.’ Monogamy. There are few species that maintain monogamous relationships between the sexes. It is commonly believed that males are more promiscuous, but new research is shedding light on the prominence of female infidelity as well as the consequences of such behavior.

Female infidelity is common in the animal kingdom as well as among humans. According to an analysis of 280 000 paternity tests conducted in 1999 by the American Association of Blood Banks, approximately 30% of children are fathered by extra-pair copulations; that is, 30% of children in this sample were fathered by someone other than the woman’s long-term romantic partner.

Current estimates of extra-pair paternity (paternity by someone other than the putative and domestic father, or ####oldry) are between 1 and 30%, with the best estimate at about 10% (Baker & Bellis, 1995; Cerda-Flores et al., 1999; Neale, Neale, & Sullivan, 2002; Sasse et al., 1994; Sykes & Irven, 2000). In other words, approximately 1 in 10 children are the product of female infidelity.

These "scientists" obviously ignored the data from Montel and Maury.
