Abstract
We simulated the molecular evolution of a neutral nucleotide sequence
using an individual-based model that involves disruptive selection. We
show that the developed approach allows us to infer important details of
evolutionary processes from a sub-sample of the sequences resulting from
a simulation. This procedure permits one to estimate the confidence
limits for the observed rate at which new sequences evolve by analysing
the shape of frequency distribution curve of the pairwise genetic
distances among all the sequences. It is shown that this approach allows
to distinguish between different scenarios of environmental changes
which are important for speciation or intraspecific genetic
diversification. This method is proposed as an alternative to the
lineage through time approach that analyses the number of lineages in a
phylogenetic tree. (C) 2004 Elsevier B.V. All rights reserved.
