The effect of genetic structure on molecular dating and tests for temporal si…

1. ‘Dated-tip’methods ofmolecular dating useDNAsequences sampled at different times, to estimate the age of their most recent common ancestor. Several tests of ‘temporal signal’ are available to determine whether data sets are suitable for such analysis.However, it remains unclear whether these tests are reliable. 2. We investigate the performance of several tests of temporal signal,…
