  bibo_abstract:
  - Shifts between adaptive peaks, caused by sampling drift, are involved in both
    speciation and adaptation via Wright's “shiftingbalance.” We use techniques from
    statistical mechanics to calculate the rate of such transitions for apopulation
    in a single panmictic deme and for apopulation which is continuously distributed
    over one- and two-dimensional regions. This calculation applies in the limit where
    transitions are rare. Our results indicate that stochastic divergence is feasible
    despite free gene flow, provided that neighbourhood size is low enough. In two
    dimensions, the rate of transition depends primarily on neighbourhood size N and
    only weakly on selection pressure (≈sk exp(− cN)), where k is a number determined
    by the local population structure, in contrast with the exponential dependence
    on selection pressure in one dimension (≈exp(− cN √s)) or in a single deme (≈exp(−
    cNs)). Our calculations agree with simulations of a single deme and a one-dimensional
    population.@eng
