Table 4 Split times (and 95 % confidence intervals) of Neomys calculated in a species tree approach with IMa2 and *BEAST using different combinations of genes and estimated mutation rates. For IMa2, the isolation-with-migration (IM) or the isolation (I) models were used. Results obtained with a direct gene tree approach of the mammalian introns using BEAST are also shown
