Just out of interest: If actual age would (should?) be playing a role,
where do we then account for differences between taxa with highly divergent
generation time, like drosophilids with perhaps more than 10 generations
per year under favourable conditions and panthophthalmids which probably
take multiple years to develop? And then I am just considering taxa within
the same order where one might give rise to new taxa on a much shorter
absolute time scale than the other.
