(A) Species tree (blue area) and allele tree (lines). Sampling just one allele per species reveals only part of what could be known about a speciation (red allele branches, or clades), whereas sampling extensively (red + light brown clades) reveals much more about timing, geographical patterns of events, etc. Dark brown extinct clades are unknowable. (B) Allele tree for a host (red) and parasite (green) that would support sympatric speciation, because the parasite is not only sister species to the host but also originated later than the host (parasite alleles originate at a later time). (C) A pattern that has been observed for mitochondrial genes implying both interspecific gene flow and rapid evolution, possibly because of “selective sweeps” of selected mutations through the species (tree labeled as in B).
