The application of evolutionary theory to human behavior has elicited a variety of critiques, some of which charge that this approach expresses or encourages conservative or reactionary political agendas. In a survey of graduate students in psychology, Tybur, Miller, and Gangestad (Human Nature, 18, 313–328, 2007) found that the political attitudes of those who use an evolutionary approach did not differ from those of other psychology grad students. Here, we present results from a directed online survey of a broad sample (...) of graduate students in anthropology that assays political views. We found that evolutionary anthropology graduate students were very liberal in their political beliefs, overwhelmingly voted for a liberal U.S. presidential candidate in the 2008 election, and identified with liberal political parties; in this, they were almost indistinguishable from non-evolutionary anthropology students. Our results contradict the view that evolutionary anthropologists hold conservative or reactionary political views. We discuss some possible reasons for the persistence of this view in terms of the sociology of science. (shrink)

Males and females of a number of animal species divide labor and provide jointly for offspring. Males may provide food, for example, while females protect defenseless young. This exchange is unlikely, however, unless a prior partnership has been established in which a female practices fidelity in exchange for a male’s provisioning activity. The formation of the trading partnership is itself an exchange, and economic theory can help explain when and why there are mutual gains from trading fidelity for resources. Environmental (...) factors determine the potential gains from trade while evolved psychological mechanisms influence the extent to which gains are realized. (shrink)

In this article, I show that principles from both evolutionary biology and evolutionary psychology inform a model of the actor that is usually implicit in sociological research on the family and social stratification. Making this evolved actor model explicit can unify and explain existing empirical sociological findings in these areas, and suggest new hypotheses for future research. I suggest the same is true in many other areas of sociology as well, and that explicitly incorporating a fully developed evolved actor model (...) into sociology can both unify the discipline and reconnect it with the other life sciences.

Two studies examined the link between social dominance and male waist-to-hip ratio (WHR). Groups of four men interacted in a leaderless group discussion. In both studies, men with higher WHRs (associated with current and long-term health status) were rated by other group members as behaving more leader-like when an observer was present, and rated themselves as being more assertive. In Study 2, men with higher WHRs were rated by independent observers as behaving more dominantly, but only when the evaluator was (...) present. These results are discussed in terms of evolutionary models of health, attraction, and intrasexual competition. (shrink)

Feminist philosophers of biology bring the tools of feminist theory, and in particular the tools of feminist philosophy of science, to investigations of the life sciences. While the critical examination of the categories of sex and gender (which will be explained below) takes a central place, the methods, ontological assumptions, and foundational concepts of biology more generally have also enjoyed considerable feminist scrutiny. Through such investigations, feminist philosophers of biology reveal the extent to which the theory and practice of particular (...) scientific disciplines and research programs (and, indeed, their philosophical study) are intertwined with both value judgments and social hierarchies.

In this paper we provide a critical review of research concerned with social/environmental mechanisms that modulate human neuroendocrine function. We survey research in four behavioral systems that have been shaped through evolution: competition, partnering, sex, and pregnancy/parenting. Generally, behavioral neuroendocrine research examines how hormones affect behavior. Instead, we focus on approaches that emphasize the effects of behavioral states on hormones (i.e., the “reverse relationship”), and their functional significance. We focus on androgens and estrogens because of their relevance to sexually selected (...) traits. We conclude that the body of research employing a reversed or bidirectional perspective has an incomplete foundation: participants are mainly heterosexual men, and the functionality of induced shifts in neuroendocrine factors is generally unknown. This area of research is in its infancy, and opportunities abound for developing and testing intriguing research questions. (shrink)

In this study some typical aspects of human behavior are reconsidered in a new evolutionary perspective. Firstly, a theoretical paradigm is introduced, according to which animals show a natural propensity to maintain behavior far beyond the time when the triggering motivation has been removed;, these drifting conducts are defined as Vestigial Drifting Drives or. Such a paradigm is then applied to those human attitudes that once conferred an adaptive advantage on our species but have now become dysfunctional within the framework (...) of the current ecological crisis. In this context, human beings are considered the repository of VDDs that may play out as evolutionary threats. This thesis is supported by many examples and references that, hopefully, could stimulate scientific debate and further research in evolutionary anthropology, psychology, and related disciplines.
