DESCRIPTION:Co-author: Alan J McKane (University of Manchester)\n\nCompeti
 tion between individuals drives the evolution of whole species. When the f
 ittest individuals survive the longest and produce the most offspring\, it
  is conventionally assumed that the resulting species will therefore also 
 be optimally fit. In fact\, this reasoning is not always correct. Using th
 eoretical analysis and stochastic simulations of a simple model ecology\, 
 we demonstrate how the fitness of evolved populations depends on the detai
 l of the competitive interaction. In particular\, if competition is mediat
 ed by the consumption of a common resource then demographic noise leads to
  the stabilisation of species with near minimal fitness.\n\nRelated Links:
