Development, Ecology, and Environment
in the Cambrian Metazoan Radiation
By Doug Irwin
The Cambrian radiation of animal life is one of the most profound episodes of evolutionary innovation in the history of life. Understanding the causes of this event requires deciphering the relative contributions of environmental triggers, developmental novelties, and changes in ecosystem structure. At present, ecology appears to have been largely responsible for the breadth and structure of this event, but we lack adequate, process-based models to understand these ecological dynamics.
