Developmental systems theory (DST) is an overarching theoretical perspective on biological development, heredity, and evolution. [1] It emphasizes the shared contributions of genes, environment, and epigenetic factors on developmental processes.
Ecological systems theory is a broad term used to capture the theoretical contributions of developmental psychologist Urie Bronfenbrenner. [1] Bronfenbrenner developed the foundations of the theory throughout his career, [2] published a major statement of the theory in American Psychologist, [3] articulated it in a series of propositions and hypotheses in his most cited book, The Ecology of ...
The history of biology traces the study of the living world from ancient to modern times. Although the concept of biology as a single coherent field arose in the 19th century, the biological sciences emerged from traditions of medicine and natural history reaching back to Ayurveda, ancient Egyptian medicine and the works of Aristotle, Theophrastus and Galen in the ancient Greco-Roman world.
The bioecological model of development is the mature and final revision of Urie Bronfenbrenner's ecological system theory. The primary focus of ecological systems theory is on the systemic examination of contextual variability in development processes. It focuses on the world outside the developing person and how they were affected by it.
He considered cognitive structures' development as a differentiation of biological regulations. When his entire theory first became known – the theory in itself being based on a structuralist and a cognitivitist approach – it was an outstanding and exciting development in regards to the psychological community at that time.
In subsequent revisions, Bronfenbrenner acknowledged the relevance of biological and genetic aspects of the person in human development. At the core of Bronfenbrenner’s ecological model is the child’s biological and psychological makeup, based on individual and genetic developmental history.
Charles Darwin in 1868. Darwinism is a term used to describe a theory of biological evolution developed by the English naturalist Charles Darwin (1809–1882) and others. The theory states that all species of organisms arise and develop through the natural selection of small, inherited variations that increase the individual's ability to compete, survive, and reproduce.
A recapitulation theory of evolutionary development was proposed by Étienne Serres in 1824–26, echoing the 1808 ideas of Johann Friedrich Meckel. They argued that the embryos of 'higher' animals went through or recapitulated a series of stages, each of which resembled an animal lower down the great chain of being .
