This is a question with some connection to a thing for Traveller that
I'm thinking about: Several years ago I encountered a 'thumb rule' of
evolution that went something like this "It take X years for a new
species to develop, Y years for a family, Z for an order, N for a new sex
and M for a kingdom." This is very aproximate and the time periods was
obviously very aproximate too.
But I'm interested in it as indicator of what is resonable and what is
not.
So, do anyone know the proper time periods for the various hierarchical
levels from kingdom to species?
