Use of literature data may occasionally be considered as an alternative source for quantifying background variation, but may present great difficulties both regarding the representativity of the data and the possibilities to discern the different components of variation.
Although the placodal origin of these populations has been traditionally accepted, it is still a matter of discussion and the neural crest is considered as an alternative source for some of them (Whitlock 2004; Barraud et al. 2010; Forni et al. 2011; Katoh et al. 2011).
