•  Developmental biology

  Developmental biology is the study of the process by which organisms grow and develop. Modern developmental biology studies the genetic control of cell growth, differentiation and "morphogenesis," which is the process that gives rise to tissues, organs and anatomy. Developmental biology is that branch of life science, which deals with the study of the process by which organisms grow and develop.

•  Ecdysis

  Ecdysis is the moulting of the cuticula in arthropods and related groups. Since the cuticula of these animals is also the skeletal support of the body and is inelastic, it is shed during growth and a new, larger covering is formed. The old, empty exoskeleton is called an exuvia (or "exuvium"). After moulting, an arthropod is described as teneral; it is "fresh", pale and soft-bodied.

•  Morphogenesis

  Morphogenesis (from the Greek morphê shape and genesis creation, literally, "beginning of the shape"), is the biological process that causes an organism to develop its shape. It is one of three fundamental aspects of developmental biology along with the control of cell growth and cellular differentiation. The process controls the organized spatial distribution of cells during the embryonic development of an organism.

•  Metamorphosis

  Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some insects, amphibians, mollusks, crustaceans, Cnidarians, echinoderms and tunicates undergo metamorphosis, which is usually (but not always) accompanied by a change of habitat or behavior.

•  Neoteny

  Neoteny, also called juvenilization, is the retention, by adults in a species, of traits previously seen only in juveniles (a kind of pedomorphosis), and is a subject studied in the field of developmental biology. In neoteny, the physiological development of an animal or organism is slowed or delayed (alternatively, seen as a dilation of biological time). Ultimately this process results in the retention, in the adults of a species, of juvenile physical characteristics well into maturity.

•  Ontogeny

  Ontogeny (also ontogenesis or morphogenesis) (ontos present participle of 'to be', genesis 'creation') describes the origin and the development of an organism from the fertilized egg to its mature form. Ontogeny is studied in developmental biology, developmental psychology, developmental cognitive neuroscience, and developmental psychobiology. Ontogeny is that branch of life science which deals with the study of origin and development of an organism from fertilized ovum to its mature form.

•  Pangenesis

  Pangenesis was Charles Darwin's hypothetical mechanism for heredity. He presented this 'provisional hypothesis' in his 1868 work The Variation of Animals and Plants Under Domestication and felt that it brought 'together a multitude of facts which are at present left disconnected by any efficient cause'. The etymology of the word comes from the Greek words pan (a prefix meaning "whole", "encompassing") and genesis ("birth") or genos ("origin").

•  Stem cell

  Stem cells are cells found in most, if not all, multi-cellular organisms. They are characterized by the ability to renew themselves through mitotic cell division and differentiating into a diverse range of specialized cell types. Research in the stem cell field grew out of findings by Canadian scientists Ernest A. McCulloch and James E. Till in the 1960s.

•  Zygote

  A zygote (from Greek ζυγωτός zygōtos "joined" or "yoked", from ζυγοῦν zygoun "to join" or "to yoke"), or zygocyte, is the initial cell formed when a new organism is produced by means of sexual reproduction. A zygote is synthesized from the union of two gametes, and constitutes the first stage in a unique organism's development.

•  Embryo

  An embryo is a multicellular diploid eukaryote in its earliest stage of development, from the time of first cell division until birth, hatching, or germination. In humans, it is called an embryo until about eight weeks after fertilization (i.e. ten weeks LMP), and from then it is instead called a fetus. The development of the embryo is called embryogenesis.
