Heterochrony and Targets of Selection

  • Michael L. McKinney

To understand the importance of heterochrony in evolution, one of the main aspects that needs to be considered is the target of selection. By this we mean intrinsically generated structures are being preferentially selected under extrinsic regimes. We have demonstrated how the raw material for evolution can be produced at the intrapopulation level by the generation of heterochronic morphotypes as part of normal phenotypic variation. Extrapolating this to the interspecific level and above, we need to examine what is being selected, e.g., shape, size, life habits, behavior, or all of these.
