Just a brief comment.

Because of the problems with a simplistic molecular clock, I tend to
focus not on estimates of divergence times but on the inferred _order_
in which derived characteristics were added to an evolving lineage.
The ordering of these branching points determined from cladograms
constructed with molecular data can be compared with those constructed
with morphological data. Furthermore, they can be compared with the
order of appearance reconstructed from our current knowledge of the
fossil record. These various methods provide multiple independent
reconstructions of branching patterns in the history of life.
