Genetic‐genealogy approach reveals low rate of extrapair paternity in historical Dutch populations

Abstract

The Dutch EPP rate fits perfectly within the range reported for other contemporary and historical populations in Western Europe and was highly congruent with that estimated for neighboring Flanders, despite the socio-economic and religious differences between both populations. The estimated low EPP rate challenges the "dual mating strategy hypothesis" that states that women could obtain fitness benefits by securing investment from one man while cuckolding him to obtain good genes from an affair partner.

Kinship and morphological similarity in the skeletal remains of individuals with known genealogical data (Bohemia, 19th to 20th centuries): A new methodological approach

“…4–7, family tree: Supporting Information, Figure S1) were selected for studying biological relationships. Although the possibility exists (approximately 1 %) that some family members may not be biologically related (Larmuseau et al, , ), the relationships and other biographical data (sex, age, state of health, etc.) of these individuals are considered to be highly reliable; doubts do not exist.…”

“…Anderson () tabulates 67 sets of primary paternity data for over 40,000 humans from six continents. To these we can add six further Y‐chromosome, genealogical‐pair studies for over 5,000 humans from two continents summarized in Larmuseau et al (). Methodology varies considerably, particularly between the studies listed by the two main sources, but all have three things in common: (a) the Designated Male is the female's in‐pair male; (b) the percentage of (as termed here) Other‐Male Paternities are provided; and (c) in most cases, the sample size is also provided.…”

“…In the six genealogical‐pair studies, we use the total number subjected to DNA‐testing, not the total number of meioses generated by the genealogies. When sample sizes are not available in Larmuseau et al (), they are taken from the original publications. The level of Other‐Male paternity, however, which is sometimes subjective, is taken from Larmuseau et al ().…”

High rate of extrapair paternity in a human population demonstrates diversity in human reproductive strategies

“…High-quality genetic evidence of EPP in humans has only begun to accumulate in the last 5 to 10 years and is focused almost exclusively on populations of European descent (12). Unlike the picture of variable rates of concurrency emphasized by anthropologists, genetic data from both contemporary and historical populations have consistently revealed very low rates of EPP (~1 to 2%) (13)(14)(15)(16)(17)(18)(19). The only modern study of paternity in a non-Western population, among the Dogon of Mali, shows a similar rate of 1.8% (20).…”
