Adaptive Landscapes and Macroevolutionary Dynamics

Adaptive Landscapes and Macroevolutionary Dynamics

(p.205) Chapter 13 Adaptive Landscapes and Macroevolutionary Dynamics
The Adaptive Landscape in Evolutionary Biology

Thomas F. Hansen

Oxford University Press

This chapter starts out with a review of what is known about the potential for evolutionary change, the strength and pattern of selection on phenotypic traits, and rates of evolution and adaptation. This is then used to discuss and evaluate quantitative genetics models for evolution on an adaptive landscape. It is argued that the predicted dynamics is too fast to adequately represent patterns of macroevolution. Instead macroevolutionary dynamics must reflect long-term changes in the adaptive landscape itself. Models and theories about the evolution of the adaptive landscape are then reviewed and critically evaluated.

Keywords:   adaptation, constraint, stasis, evolvability, macroevolution, evolution rate, quantitative genetics
