Using phylogenetic comparative analyses, I examined the hypothesis that a difference in the rates at which Tpref and Topt evolve causes the mismatch in a lineage of European newts. In a laboratory thermal gradient, newts maintained body temperatures that were on average 8°C below Topt for maximum swimming velocity. The lower boundary of the Tpref range evolved faster than the mean Tpref, the upper boundary of the Tpref range, and Topt. The strong evolutionary co-variation between mean Tpref and its boundaries prevented the shift of mean Tpref away from Topt. This suggests that the variation in evolutionary rates has a limited potential to modify the disparity between thermal optima and preferenda.
