Plenty of people have tried, and not gotten far. Anyway, the goal
is to find the most parsimonious cladogram, *all else being equal*.
And the real debate is over what that "all else" should consist of.
Hybridization (aka recombination or reticulation) is a hard problem
also in HIV research, but perhaps the biggest problem at present is
the preliminary challenge of figuring out what is a hybrid and what
is not a hybrid.
