Rates of phenotypic evolution have changed throughout the history of life, producing variation in levels of morphological, functional, and ecological diversity among groups. General predictions regarding changes in phenotypic diversity as a function of evolutionary history and rates are developed, and tests are derived to evaluate rate changes. Species delimitation and species tree inference are difficult problems in the case of recent divergences, especially when different loci have different histories. I quantify the difficulty of the problem and introduces a nonparametric method for simultaneously dividing anonymous samples into different species and inferring a species tree, using individual gene trees as input. The phylogeny of Myrmecocystus ants is estimated using nine loci. Evolution of foraging time and coevolution of behavior and morphology in Myrmecocystus ants is examined. New models for reconstructing discrete states along branches of a tree and for examining continuous trait evolution and coevolution with discrete traits are developed and implemented. Foraging transitions between diurnal and nocturnal foraging evidently go through crepuscular intermediates. There is some evidence for increased rates of morphological character evolution associated with changes in foraging regime, but little evidence for particular optimum values for morphological traits associated with foraging.
