Such sophisticated body architecture is elaborated during embryonic development, whereby a fertilized egg undergoes a program of cell divisions, fate specification, and movements. This is the currently selected item. including genetics, development, physiology, evolution, and It is the field of biology that studies the processes by which multicellular organisms grow and develop, controlled by their genes.  It involves the study of mechanisms of development, differentiation, and growth in animals and plants at the molecular, cellular, genetic and evolutionary levels.
