Hi John.
There is no problem simulating discrete characters on non-ultrametric
trees. You can use sim.char in geiger, sim.history in phytools, or a
number of other functions, in fact.
All the best, Liam

Hi all,
I'm curious to know whether there is a function for evolving discrete character
data onto a non-ultrametric tree. I know sim.char() can technically produce
output given a non-ultrametric tree, and the documentation does not specify
that it is a requirement, but all the example trees I
