Abstract:
For many questions in evolutionary ecology, it is quite valuable to have an estimate of the span of geologic time over which a group of species has arisen and diversified. This study uses a molecular clock approach to generate a first estimate of key divergences in the evolutionary history of the genus Helianthus, which to date has lacked such an estimate.
