AbstractThe geography of speciation has long been contentious.
In recent years, phylogenetic approaches have been proposed to
determine the geographical mode of speciation. If reliable,
these methods not only provide a means of settling the debate
about the geography of speciation, but also indicate that
sympatric speciation is surprisingly common and that peripatric
speciation is relatively rare. Similar to any phylogenetic
inference, reconstructions of speciation mode are only useful if
the underlying assumptions of the method are met. In this case,
the key assumption is that the geographical range of both extant
and ancestral species at the time of speciation can be inferred
from present-day distributi
