Developmental biology is the study of how organisms grow and develop from a single cell into complex structures. This field examines the processes that guide cell division, differentiation, and morphogenesis, which are essential for forming tissues and organs. Researchers in this area often focus on model organisms like Drosophila melanogaster (fruit flies) and Mus musculus (mice) to understand these fundamental biological processes. The discipline also explores genetic and environmental factors that influence development. By studying embryonic development, scientists can uncover the mechanisms behind congenital disorders and potential regenerative medicine applications. Overall, developmental biology provides insights into the intricate journey of life from conception to maturity.
