In the history of ideas, the continuity thesis is the hypothesis that there was no radical discontinuity between the intellectual development of the Middle Ages and the developments in the Renaissance and early modern period. Thus the idea of an intellectual or scientific revolution following the Renaissance is, according to the continuity ...
Also gastrocoel. The central internal cavity of the gastrula in most animal embryos, fated to develop into the lumen of the digestive tube ; the primitive gut. The archenteron initially has only one open end, known as the blastopore. B birth blastocoel Also blastocoele, blastocele, cleavage cavity, and segmentation cavity. The fluid-filled or yolk -filled cavity that forms in the developing ...
Developmental biology is the study of the process by which animals and plants grow and develop. Developmental biology also encompasses the biology of regeneration , asexual reproduction , metamorphosis , and the growth and differentiation of stem cells in the adult organism.
Special methods are used in the psychological study of infants. Piaget's test for Conservation.One of the many experiments used for children. Developmental psychology is the scientific study of how and why humans grow, change, and adapt across the course of their lives.
Also called "development in context" or "human ecology" theory, ecological systems theory was originally formulated by Urie Bronfenbrenner.It specifies four types of nested environmental systems, with bi-directional influences within and between the systems; they are the microsystem, mesosystem, exosystem, and macrosystem.
In biology, a biological life cycle (or just life cycle when the biological context is clear) is a series of stages of the life of an organism, that begins as a zygote, often in an egg, and concludes as an adult that reproduces, producing an offspring in the form of a new zygote which then itself goes through the same series of stages, the ...
Modern evolutionary developmental biology (evo-devo) studies the molecular genetics of development. It seeks to explain each step in the creation of an adult organism from an undifferentiated zygote in terms of the control of expression of one gene after another. Further, it relates such patterns of control of development to phylogeny.
The term ontogeny has also been used in cell biology to describe the development of various cell types within an organism. [4] Ontogeny is a useful field of study in many disciplines, including developmental biology, cell biology, genetics, developmental psychology, developmental cognitive neuroscience, and developmental psychobiology.
