 The schematic illustrates an important point about the biological reality of polytomies.

 so as the result of two successive bifurcations. This is \emph{necessarily} so,
 because the only known method of reproducing DNA is by (semi-conservative) duplication.
 Whether this polytomy is resolvable depends on the available mutational data.
