Size Disparity in Putative Primate Adaptive Radiations and Other Mammalian Clades

Key Points

This research aims to investigate whether adaptive radiation influences size disparity in mammals, focusing on primates.
Analyzed size distributions of various mammalian clades
Compared size disparity in lemuriforms and platyrrhines
Evaluated criteria for identifying exceptional clades
No evidence of exceptional clades based on size disparity
Found positive skew and no bimodality in size distributions
Lemuriforms and platyrrhines exhibit magnitudes of disparity consistent with adaptive radiation

Abstract

If adaptive radiation has influenced size evolution in mammals, the effect is not apparent in the distributions of size disparity. Without outliers, positive skew, or bimodality, there are no criteria for identifying exceptional clades. The magnitudes of disparity found in lemuriforms and platyrrhines can be interpreted as consistent with adaptive radiation, but size disparity does not provide decisive support for recognizing them as such.
