(c) To show that recognitional abilities are not sufficient either, Raymont cites empirical data "in support of the view that one can have the ability to noninferentially recognize a certain type of visual experience without ever having had it, and thus without knowing what it is like to have it".
Practical exploitation of heterogeneous transmission requires the sources of variability to be quantified, yet it is unusual to have empirical data of sufficient resolution to distinguish their effects.
Although molecular tools provide sufficient power in detecting genetic variation, empirical data on species delimitation are often difficult to interpret, since both gene introgression after speciation and shared ancestral polymorphisms can result in species paraphyly [ 15].
While multiple systems of drawing biogeographical boundaries have been proposed, empirical data have rarely been sufficient to test their rigor.
