Cross-species comparisons in neuropsychology are designed to understanding the basic mechanisms of brain function. Claudia hetzer-egger a gene called pax, is responsible for eye development in all seeing animals, demonstrating a much closer relationship among very diverse kinds of animals. Homeobox genes similar genes, dictate body segmentation in both fruit flies and humans. Mutations slight alterations that produce, for example, differences in structure of the eye and nervous system in different animals.
