 Axel Barceló Aspeitia and Angeles Eraña focused their work mainly on the modularity of mind in order to adapt the idea of domain specificity (Barceló, Eraña, and Stainton 2010) and to compare the hypothesis of massive modularity to other views about the structure of mind (Eraña 2012). In this context, Claudia Lorena García (2007) argues that the hypothesis of the modularity of mind needs to be understood in terms of the evolutionary biological concepts of variational independence (2007) and of functional homology and functional variation (2010).
