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

+Three lineages coalesce in the left-hand genome of individual $D_{10}$, but do
 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.
