SUMMARY:Gene Surfing and Survival of the Luckiest
DESCRIPTION:Featuring David Nelson\, Harvard University\nHosted by: Rama Ba
	nsil\nPoster: http://physics.bu.edu/posters/2012_Spring/03_Nelson.pdf\n\nPa
	rt of the Physics Department Colloquia Series.\n\nAbstract:\nIt is widely a
	ppreciated that population waves have played a crucial role in the evolutio
	nary history of many species. In parallel with Fokker-Planck descriptions o
	f stochastic processes in physics\, population geneticists have developed m
	ethods for understanding mutations\, genetic drift and selective advantage 
	in such situations.   Provided number fluctuations at the frontie
	r are taken into account\, neutral genetic markers can be used to infer inf
	ormation about growth\, ancestral population size and colonization pathways
	.   Mutations optimally positioned at the front of a growing popu
	lation wave can increase their abundance via a "surfing" phenomenon. Experi
	mental and theoretical studies of this effect will be presented\, including
	 recent work on bacteria and on mutualistic strains of yeast.
