My NIMBioS Seminar – Tomorrow 3:30 EST @ University of Tennessee


For anyone around Knoxville tomorrow I will be giving a seminar at NIMA picture of me.BioS at the University of Tennessee at 3:30 EST (refreshments at 3:00 EST). Here is the information:

Time/Date: Tuesday, October 8, 2013, 3:30 p.m.
Location: Room 105, Claxton Building, 1122 Volunteer Blvd.
Speaker: Dr. Matthew Zimmerman, NIMBioS postdoctoral fellow
Topic:Cultural evolution of human cooperation and conflict

Abstract: Humans seemingly have a greater capacity for altruistic cooperation with non-relatives than any other species. For example, in experiments humans cooperate more than one would expect either from cross-species comparisons or by calculating payoff-maximizing behavior. Two main hypotheses have sought to explain this – the mismatch hypothesis, where humans evolved genetically-inherited rules for cooperation in small kin groups and misapply them in modern contexts, and the norm psychology hypothesis, where humans evolved the capacity for to learn cooperative norms. I show that a model developed to support the former hypothesis actually better supports the latter. Similarly, in warfare humans take large risks to benefit group members who are mostly non-relativ
es. Quite a few hypotheses have been proposed to explain this, however these hypotheses are fundamentally incomplete when they do not account for both cultural inheritance and group-structure. Finally, explaining cooperation in larger-scale complex human societies has been difficult since many of the institutions that work in small-scale societies become less effect ive as group size increases. Hierarchical organization seems a potential solution to increasing group size, though the basic theory has not been established. I present a preliminary model of hierarchy’s origins that I will develop as a NIMBioS post-doc.
