Alternative models of evolutionary processes suggest different associations between species diversification and trait evolution, but limited empirical evidence is available to test these models across large clades at global extents. Here we investigate the relative timing of species diversification and niche and phenotypic evolution across a global plant radiation (Saxifragales) with enormous phenotypic and habitat variation. We demonstrate strong temporal lags among rates, with increased diversification occurring first, followed by niche and phenotype. Accelerated diversification rates are coincident with mid-Miocene expansion of temperate biomes. Later increases in niche and phenotypic evolutionary rates argue against density-dependent diversification alone, indicating a major role for ecological opportunity. These results have broad implications for understanding diversification processes and the origin of present-day temperate biotas.

The Great Tree of Life is a concise, approachable treatment that surveys the concept of the Tree of Life, including chapters on its historical introduction and cultural connection. The Tree of Life is a metaphor used to describe the relationships between organisms, both living and extinct. It has been widely recognized that the relationship between the roughly 10 million species on earth drives the ecological system. This work covers options on how to build the tree, demonstrating its utility in drug discovery, curing disease, crop improvement, conservation biology and ecology, along with tactics on how to respond to the challenges of climate change.
This book is a key aid on the improvement of our understanding of the relationships between species, the increasing and essential awareness of biodiversity, and the power of employing modern biology to build the tree of life.
