Abstract

Earlier we have shown that oscillations with a long period (''supercycles'') may arise in two-locus systems experiencing cyclical selectionwith a short period. However, this mode of complex limiting behavior appeared to be possible for narrow ranges of parameters. Here we demonstrate that a multilocus system subjected to stabilizing selection with cyclically moving optimum can generate ubiquitous complex limiting behavior including supercycles, T-cycles, and chaotic-like phenomena. This mode of multilocus dynamics far exceeds the potential attainable under ordinary selection models resulting In simple behavior. It may represent a novel evolutionary mechanism increasing genetic diversity over longterm time periods.
