SUMMARY:Richard McElreath - The endogenous Dorito: The cultural evolution of evolutionary mismatch
DESCRIPTION:Richard McElreath: UC Davis Department of AnthropologyIt’s common for evolutionary psychologists to invoke evolutionary mismatch as an explanation for maladaptive human behavior. For example\, people eat themselves to death\, because our food preferences evolved in a past environment with scarcity. Mismatch has also been invoked to explain the tendency for humans to cooperate with strangers and non-kin\, and mismatch is usually presented as an alternative to cultural evolutionary processes\, such as cultural group selection. I argue that every example of evolutionary mismatch is a study in cultural evolution and likewise that every example of cultural evolution is a study in evolutionary mismatch. The two processes cannot usually be separated in analysis\, as successful cultural institutions and beliefs are adapted to evolved human psychology. Likewise\, evolved psychology alone is an insufficient explanation\, because cultural forms evolve to manipulate it.

SUMMARY:David Nolin - What goes around comes around? Cyclicity as a statistical test of generalized reciprocity in social   network data.
DESCRIPTION:David Nolin: Boise State University Department of AnthropologyGeneralized (indirect) reciprocity is characterized by giving to other group members without regard to direct reciprocation from those same recipients\, with the costs of the donor’s generosity instead offset by transfers from other group members. This pattern has long been noted by anthropologists as a common feature of foraging societies; however\, there have been relatively few quantitative tests of the principle. One basic test is to see if what one gives is correlated with what one receives – a correlation of indegree and outdegree in network terminology. However\, a more specific test is to look for evidence of cycles in the network: A gives to B\, who gives to C\, who gives back to A. Using between-household food-sharing data from the fishing and whaling village of Lamalera\, Indonesia\, I test for evidence of cyclical exchange. Previous analyses have shown strong support for direct (dyadic) reciprocity in this population but this additional analysis finds no evidence of cyclical exchange. Instead\,there is a significant propensity to form transitive triads (A gives to both B and C\, and B also gives to C). This result is compared to ethnographic observations of social support via food transfers from economically secure to chronically needy households.

SUMMARY:Andrew Gersick - Courtship Signaling in a Social Context: What Flirting and “Flirting” May Do for Humans\, Birds and Others.
DESCRIPTION:Andrew Gersick: University of Pennsylvania Department of Animal BehaviorSexual selection is widely understood through the lens of the peacock’s tail – as the evolutionary driver shaping elaborate\ncourtship displays and signals. Less studied is the influence of sexual selection on cognitive abilities or behaviors that allow individuals to regulate how they use those signals. Prevailing theory suggests\, for example\, that courting males always present their sexually selected signals at maximum intensity and thus exhibit their capacity to bear the associated signaling costs. Yet many social creatures face shifting competitive contexts that would reward more flexible control over signaling behavior. Humans are an obvious example: we conduct our courtship within complex networks of potential eavesdroppers\, many of whom may have an interest in our sexual signaling efforts. I propose that the covert linguistic signals we call flirtation are an adaptive response to the shifting competitive pressures that surround human courtship. I will also discuss experiments with another social class of animals with a sophisticated communication system – songbirds – demonstrating that humans’ flexible signaling is far from unique.

SUMMARY:Eli Berman - Predation\, Taxation\, Investment and Violence: Evidence from the Philippines
DESCRIPTION:Eli Berman: UCSD Department of Economics This paper explores the relationship between investment and political violence through several possible mechanisms. Investment as a predictor of future violence implies that low private sector investment today provides a robust indicator of high violence tomorrow. “Rent-capture” or predation asserts that investment increases violence by motivating extortion by insurgents. A “hearts and minds” approach links investment to political violence in two possible ways: through an opportunity cost mechanism by which improved economic conditions raise the cost of rebel recruitment; and through a psychological “gratitude” effect which reduces cooperation of noncombatants with rebels. Finally\, tax capture implies that government will increase coercive enforcement in an attempt to control areas where increased investment increases tax revenue. We lay out these mechanisms in a framework with strategic interaction between rebels\, communities\, government and firms within an information-centric or “hearts and minds” counterinsurgency model. We test these mechanisms in the context of the Philippines in the first decade of this century\, using information on violent incidents initiated by both rebels and government and new data on industrial building permits\, an indicator of economic investment. Increases in investment are positively correlated with both rebel and government initiated violence. In the context of our theory that constitutes unequivocal evidence of predation\, is consistent with tax capture\, and weighs against predictive investment\, opportunity costs or gratitude being a dominant effect.

SUMMARY:Karen Kramer - When Mothers Need Others. The Evolution of Parenting\, Childhood & Cooperation
DESCRIPTION:Karen Kramer: University of Utah Department of Human Evolutionary Biology Human life histories differ from those of other closely related species in ways that significantly affect parental care and childhood. Most explanations for the hominization of life histories incorporate ideas about social interdependence and cooperative breeding.  While cooperation for the purposes of raising children is often presumed to be ancient\, it leaves no known fossil record or genetic signature. To address this empirical gap\, I will first discuss the evolution of parenting and childhood\, and then develop a simulation that looks at the question\, when do mothers need others? I will conclude by asking what is it that we can actually say about the past\, and suggest from model results that an age division of labor and exchanges between mothers and juveniles are an important gateway in the evolution of human sociality and cooperation.https://docs.google.com/viewer?a=v&pid=gmail&attid=0.1&thid=141e1e4c99b38333&mt=application/pdf&url=https://mail.google.com/mail/u/0/?ui%3D2%26ik%3D49bcb6aeab%26view%3Datt%26th%3D141e1e4c99b38333%26attid%3D0.1%26disp%3Dsafe%26zw&sig=AHIEtbQrR-sW3OQ5YGN4zMmkW5gWeuzd0A
