SUMMARY:Gene Surfing and Survival of the Luckiest\, Physics Department
  Colloquium\, David Nelson\, Harvard University
DESCRIPTION:It is widely appreciated that population waves have played
  a crucial role in the evolutionary history of many species.   In para
 llel with Fokker-Planck descriptions of  stochastic processes in physi
 cs\, population geneticists have developed methods for understanding m
 utations\, genetic drift and selective advantage in such  situations. 
 Provided number fluctuations at the frontier are taken into account\, 
 neutral genetic markers can be used to infer information about growth\
 , ancestral population size and colonization pathways.  Neutral mutati
 ons optimally positioned at the front of a growing population wave can
  increase their abundance via a  "surfing" phenomenon.  Experimental a
 nd theoretical studies of this effect will be presented\, as well as r
 ecent attempts to extend statistical dynamics ideas to microorganisms 
 cooperating and competing in the turbulent environment of the ocean.
