Additionally, scientists during this period constructed mathematical models to better understand the physical principles of embryology, such as the Law of Recapitulation, and interconnections among genetic, environmental and physiological factors.Įven in our modern day, the study of embryology, or the scientific field of developmental biology, is constantly evolving.
This was a time of exploration, hypothesis and experiment: researchers developed anatomical tools, such as the optical microscope and microtomes, which allowed them to investigate the intricate details of embryonic development. In the 19th and early 20th centuries, observations and research catalyzed a rapid progression in embryological advancement.
