Ontogeny

Ontogeny (also ontogenesis or morphogenesis) describes the origin and the development of an organism from the fertilized egg to its mature form. Ontogeny is studied in developmental biology.

The idea that ontogeny recapitulates phylogeny, i.e., that the development of an organism exactly mirrors the evolutionary development of the species, is discredited today. Nevertheless, many connections between ontogeny and phylogeny can be observed and explained by evolutionary theory.

Morphogenesis: Morphogenesis (from the Greek morph? shape and genesis creation) is one of three fundamental aspects of developmental biology along with the control of cell growth and cellular differentiation. Morphogenesis is concerned with the shapes of tissues, organs and entire organisms and the positions of th...

Organism: In biology and ecology, an organism (in Greek organon = instrument) is an assembly of organs that influence each other in such a way that they function as a more or less stable whole and have properties of life....
