This paper addresses methodological and metatheoretical aspects of the ongoing debate over the adaptive significance of Tibetan polyandry. Methodological contributions include a means of estimating relatedness of fraternal co-husbands given multigenerational polyandry, and use of Hamilton’s rule and a member-joiner model to specify how inclusive fitness gains of co-husbands may vary according to seniority, opportunity costs, and group size. These methods are applied to various data sets… 

Adaptationism – how to carry out an exaptationist program

The standards of evidence that could be used to identify adaptations and when and how they may be appropriately used are discussed and building an empirical case that certain features of a trait are best explained by exaptation, spandrel, or constraint requires demonstrating that the trait's features cannot be better accounted for by adaptationist hypotheses.

All the while, the traditional social sciences have remained steadfastly unwilling to accept that evolutionary approaches to human behaviour have any merit or relevance, and indeed have abandoned the scientific method in favour of more politically motivated interpretive methods.

Why do good hunters have higher reproductive success?

The qualitative and quantitative evidence bearing on these explanations are examined and it is concluded that although none can be definitively rejected, extensive and apparently unconditional sharing of large game somewhat weakens the first three explanations.

On the Decline of Marriage in Rural Ireland 1851–1911: The Role of Ecological Constraints and/or Developing Philopatry

The proportion of people who never married and the age at first marriage increased in rural Ireland after the famine (1845–1847). In 1851, 11% of the population were never married at 45–54 years and

Obstacles and catalysts of cooperation in humans, bonobos, and chimpanzees: behavioural reaction norms can help explain variation in sex roles, inequality, war and peace

It is concluded that human nature should be seen as consisting of evolved reaction norms, and variation in three behavioural contexts: relationships between the sexes, hierarchy and inequality, and intergroup interactions.

Behavior, ecology and genetics of Geoffroy's tamarin (Saguinus geoffroyi)

It is shown that tamarins spend significantly more time in secondary forest habitat and are more likely to forage and engage in social behavior in forest as compared to human-modified habitats and the role of two aquatic barriers of varying age in creating population genetic structure in S. geoffroyi is examined.

The author suggests that a process of cultural selection, or preservation by preference, driven chiefly by choice or imposition depending on the circumstances, has been the main but not exclusive force of cultural change, and shows that this process gives rise to five major patterns or modes in which cultural change is at odds with genetic change.
