In mammals, this takes place in the seminiferous tubules of the male reproductive system. Developmental biology is a branch of natural science that studies a variety of interactions involved in the formation of the heterogeneous shape, structure, and size of different organisms that occur during the development of an embryo into an adult. Developmental biology studies the mechanisms of development, differentiation, and growth in both plants and animals at the cellular, molecular, genetic, and evolutionary levels. temporal measures of larval ontogeny do not correlate tightly with the concern of non-representativeness (Davis 2004; Rubin 1988).
