text: 'Classical models of gene flow fail in three ways: they cannot explain large-scale
patterns; they predict much more genetic diversity than is observed; and they
assume that loosely linked genetic loci evolve independently. We propose a new
model that deals with these problems. Extinction events kill some fraction of
individuals in a region. These are replaced by offspring from a small number of
parents, drawn from the preexisting population. This model of evolution forwards
in time corresponds to a backwards model, in which ancestral lineages jump to
a new location if they are hit by an event, and may coalesce with other lineages
that are hit by the same event. We derive an expression for the identity in allelic
state, and show that, over scales much larger than the largest event, this converges
to the classical value derived by Wright and Malécot. However, rare events that
cover large areas cause low genetic diversity, large-scale patterns, and correlations
in ancestry between unlinked loci.'
