    Population and Evolutionary Biology Research Group, School of Biological Sciences, University of Liverpool, Liverpool, UK
    J Evol Biol 16:47-54. 2003
    ..Growth under competition appears comparable with "the tragedy of the commons", much analysed in social sciences. Our LHS prediction suggests that evolution generates a solution that seems cooperative but is actually selfish...
