Upcoming Events



Coevolution of social behavior and social networks

Erol Akcay, Ph.D., University of Pennsylvania
- | Tedori Family Auditorium, Levin Building

The evolution of social behaviors is crucially determined by social structure, i.e., the pattern of interactions between individuals in a population. I explore how this social structure itself can evolve through…



The Genomic Basis of Environmental Adaptation in House Mice

Michael Nachman, Ph.D., UC Berkeley
- | Tedori Family Auditorium, Levin Building

A major goal in biology is to understand the genetic details of how organisms adapt to novel environments.  I will discuss recent studies on the genetic basis of environmental adaptation in…



The evolution of seasonal camouflage

Jeffrey Good, Ph.D., University of Montana
- | Tedori Family Auditorium, Levin Building

Adaptation to environmental change is central to the origin and persistence of species. Mismatches between the timing of key life history events and optimal environmental conditions have emerged as an important…
