Biology Developmental Biology is the branch of biology that studies the processes by which organisms grow and develop, from the fertilization of an egg through to the mature form of the organism. This field encompasses a range of biological disciplines, including genetics, cell biology, and embryology, to understand how cells divide, differentiate, and integrate into complex tissues and organs. Researchers in developmental biology explore mechanisms such as gene expression, signaling pathways, and the role of the environment in shaping the development of organisms, thus providing insights into normal development as well as developmental disorders.
