Evolution and development are the two biological processes most associated with the idea of organic change. Indeed, the very notion of evolution originally referred to the unfolding of a preformed structure within the developing embryo and only later acquired its current meaning as the transformation of species through time. It seems, therefore, only logical to assume that the biological disciplines that study these two different phenomena- embryology, later transformed into developmental biology, and evolutionary biology, especially phylogenetics-would be closely related
