Da. Rand et Hb. Wilson, EVOLUTIONARY CATASTROPHES, PUNCTUATED EQUILIBRIA AND GRADUALISM IN ECOSYSTEM EVOLUTION, Proceedings - Royal Society. Biological Sciences, 253(1337), 1993, pp. 137-141
We introduce a new mechanism for evolutionary discontinuities in ecosy
stems and discuss the relation with punctuated equilibria, stasis and
gradualism. We conclude that these phenomena are natural consequences
of a nonlinear dynamic approach to evolutionary stability. In addition
we discuss some insights into speciation and the role of phenotype co
nstraints in determining the validity of the Red Queen hypothesis.
