We consider a class of simple two-dimensional discrete models representative of a system incorporating both mutationand predation. A selection of analytic and numerical results are presented, classifying the dynamic behaviour of the systemby means of Lyapunov exponents over a biologically-reasonable region of parameter space, and illustrating the occurrenceof hyperchaos and a Neimark-Sacker bifurcation producing regions of quasiperiodicity.
