batatas evolved in pre-human times. We show that inferring an age estimate for Ipomoea and major clades within Ipomoea is highly problematic. Inferred divergence times are sensitive to uncertain fossil calibrations and differing assumptions about among-branch-substitution-rate-variation. Despite this uncertainty, we are able to make robust inferences about patterns of variation in diversification parameters within Ipomoea, and that the storage root of I. batatas evolved in pre-human times. Taken together, this study presents novel an
