Additional attendees from network members will be charged tuition. This year, SFI is holding two summer schools - one in Santa Fe and one in Budapest, Hungary, so it will be important to get the registrations in early. Michael is also a recent member of SFI's Board of Trustees. The links are from the talk description on the agenda. OCT 7 2000.
Genetic relatedness is a central concept in the study of social evolution.
Though originally defined in terms of genealogy, the modern version of relatedness accommodates genetic similarity of any origin. This paper examines relatedness in group structured modes, in which a trait affects the fitness of all group members. Both trait types are common in nature as well as in theoretical models, but they have rarely been distinguished clearly. The average relatedness of recipients to actors differs for the two trait types within the same population and even the same individual, leading to different selection pressures and evolutionary outcomes. Recognizing the distinction between these trait types resolves some apparent contradictions in the literature, and clarifies the limits of some previous results.
