<p>I was wondering if there was a Python program that detects convergent and divergent evolution on a tree. I am also curious if it is just better to look at a phylogenetic tree and conclude what is convergent or divergent evolution than what a program tells you.</p>

Is there a Python program that is able to show convergent and divergent evolution on a phylogenetic tree?
