SUMMARY:Ecology and the evolution of reproductive isolation\, Chaos & 
 Complex Systems Seminar\, Jenny Boughman\, UW Department of Zoology
DESCRIPTION:My research program addresses two venerable questions in e
 volutionary biology: How do new species arise? How does selection caus
 e genetic change in nature? Both questions have a rich history in evol
 utionary biology going back to Darwin and the modern synthesis. Despit
 e decades of research\; however\, we have only recently begun to revea
 l the mechanisms that generate new species in nature. Recent years hav
 e also seen phenomenal progress on understanding the genetic basis of 
 traits. We are now able to ask questions that were simply impossible t
 o address 20 years ago. Yet\, progress on understanding how selection 
 is acting in natural populations to cause evolutionary change at the g
 enetic level has lagged behind. My work melds two rapidly advancing ar
 eas - mechanisms of speciation and genetics of adaptation - to investi
 gate questions of fundamental importance to our understanding of biodi
 versity. I use an ideal system to study these questions - species pair
 s of stickleback fish (Gasterosteus spp.) found in the postglacial lak
 es of British Columbia. These are extremely young species and provide 
 a window on the speciation process. Evolutionary replication allows di
 rect experiments to test the evolutionary mechanisms involved.<br>
