No, but Nelson wrote a paper back in the early eighties about how to
identify possible reticulation events on a cladogram which has the character
distributions mapped on. The goal was to develop a protocol for placing
reticulation lines on the cladogram. I dont know whether anyone ever ran
with that, but it sure made me feel good to know that someone was thinking
about it, while I went off to find myself some "well-behaved" group.....:)
