Origination Patterns and Multilevel Processes in Macroevolution
Origination Patterns and Multilevel Processes in Macroevolution
This chapter deals with the large-scale evolutionary processes underlying patterns of phenotypic innovation. It describes the origin of evolutionary novelties, specifically their nonrandom origins in time and space, which demands novel approaches to the evolution of form, and considers the fates of novelties and the clades they define. The chapter suggests that the spatial and temporal regularities in the origin of phenotypic novelties are just one aspect of macroevolution which seems to need an expansion of evolutionary concepts and methods. It appears that multilevel approaches are significant in the understanding of long-term evolutionary processes.
Keywords: phenotypic innovation, phenotypic novelties, multilevel approaches, evolutionary processes
