Phylogenetic trees are not reconstructions of evolution, they are structures of data. Darwin produced a theory of evolution from structures of data, involving informal clustering. Phylogeneticists refuse to produce theories of evolution of descent with modification particular to cluster-produced structures of information about some group. 

There is one diagram in the Origin of Species. It is more like a Besseyan cactus than a cladogram.

Besides, just because my analysis suggests that group A is a 
monophyletic, that doesn't mean it really is.  Just that the data on  hand suggest it is.  By what criterion do I know that the reconstruction is accurate?
