Abstract
For nearly as long as molecular sequence data have been available for plants, they have been used to construct phylogenetic hypotheses and date the origin and diversification of clades (e.g., Boulter et al. 1972; Ramshaw et al. 1972). These studies infer evolutionary history of plants from patterns of molecular variation, and consequently, they rely in part on assumptions about the processes that create this variation. The availability of more and more molecular data have revealed increasingly complex patterns of evolution, resulting largely from the pervasive and highly nuanced effects of selection at the molecular level. Methods of evolutionary inference now must confront this molecular complexity. In this chapter, I review some of the factors associated with molecular rate variation in plants and discuss how insights into molecular evolution both inform and confound our ability to infer divergence times from molecular data.
