Comparative study of reproductive skew and pair‐bond stability using genealogies from 80 small‐scale human societies
OBJECTIVES: Genealogies contain information on the prevalence of different sibling types that result from past reproductive behavior. Full sibling sets stem from stable monogamy, paternal half siblings primarily indicate male reproductive skew, and maternal half siblings reflect unstable pair bonds. METHODS: Full and half sibling types are calculated for a total of 61,181 siblings from published genealogies for 80 small-scale societies, including…
The Ecology of the Barí
Beckerman, Stephen and Lizarralde, Roberto (2013) The Ecology of the Barí: Rainforest Horticulturalists of South America, University of Texas Press ( Austin, TX), xv + 273 pp. $55.00 hbk. The Ecology of the Barí represents an important contribution to human behavioural ecology. Beckerman and Lizarralde have collected and analysed a wealth of data on the ecology and demography of the Chibchan speaking Barí horticulturalists of Venezuela and Colomb…

Co-father relationships among the Suruí (Paiter) of Brazil
Partible paternity refers to the conception belief that children can have multiple fathers (“co-fathers”) and is common to indigenous cultures of lowland South America. The nature of social relationships observed between co-fathers reveals information about the reproductive strategies underlying partible paternity. Here we analyze clan, genealogical, and social relationships between co-fathers for the Suruí, an indigenous horticultural population…
Relatedness, Co-residence, and Shared Fatherhood among Ache Foragers of Paraguay
Hypotheses on the benefits of the practice of partible paternity are tested using demographic data for Ache foragers of Paraguay. Partible paternity refers to the institution of multiple males considered to contribute to the conception of a single offspring. Analyses focus on patterns of primary and secondary co-fatherhood among men, genealogical relationships between co-fathers, and relation between band co-residence and co-fatherhood. Results i…
Human Female Orgasm as Evolved Signal
Evolutionary History of Hunter-Gatherer Marriage Practices
BACKGROUND: The universality of marriage in human societies around the world suggests a deep evolutionary history of institutionalized pair-bonding that stems back at least to early modern humans. However, marriage practices vary considerably from culture to culture, ranging from strict prescriptions and arranged marriages in some societies to mostly unregulated courtship in others, presence to absence of brideservice and brideprice, and polyandr…
