Abstract

The roots of mammalian diversity The textbook view of mammalian evolution is one of an adaptive radiation, in which all the major forms arose to fill the available ecological niches in an explosive burst beginning around 90 million years ago, followed by much slower adaptive change leading up to the present. In a statistical study, Mark Pagel and colleagues track the evolutionary trends in body size for a complete phylogeny of the Mammalia and find no evidence for classic adaptive radiations at any point in history. Rates of speciation and morphological evolution are decoupled and there is no early evolutionary burst. Instead, body size evolution occurs in sporadic bursts across the phylogenetic tree.
