Dear list,
I am tracing evolution of a binary trait on a phylogeny with 1500 tips.
Since the trait is labile and scattered across the phylogeny (Fritz Purvis
D= 0.45), I find it difficult to visually count the number of gains/origin
of the trait in ancestral state reconstruction. Is there any function to
estimate the number of independent gains and the respective node number if
possible? I am currently mapping the trait using *simmap *function from

Thanks in advance,
Gopal M
