History and Origins
Developmental biology has its roots in ancient Greek philosophy, with Aristotle being one of the first to document observations on the development of embryos. However, it wasn’t until the 19th and 20th centuries that significant advancements were made in this field, particularly with the rise of embryology and genetics.
Key figures such as Theodor Boveri, Walter Sutton, and Thomas Hunt Morgan made groundbreaking discoveries that laid the foundation for our current understanding of developmental processes.
