The ontogenetic development of the pectoral girdle in seven anuran species ( Xenopus laevis, Discoglossus pictus, Bombina bombina, Bombina variegata, Pelobates fuscus, Bufo bufo and Rana dalmatina) was studied using cleared and stained specimens. The epicoracoid cartilage was found to develop in two different ways … Webstudy of evolution results from the lack of a theory of development that is able to predict morphologies from patterns of gene activity. To date, theories useful for understanding particular aspects of devel-opment include reaction-diffusion sys-tems (Turing, 1952; Meinhardt, 1982), models of mechanical interactions (Oster
