If we had the true genealogy of all individuals, living and dead, of a
large group of sexually-reproducing organisms, and plotted it in a
standard form, we'd see areas where the patterns were reticulate, and
other areas where they were divergent. The splits where one reticulum
separates from another are speciation. The results are species. If
that's not "special", I'm not sure whether anything in biology is
special. Of course, I'm prejudiced, because I studied speciation.
