The invention of optical microscopes, which began around 1600, began laying the groundwork for the development of cell theory. The transition to modern biology appears to have occurred between the late 18th and the early 19th century, at which time biology came into its own as a legitimate, separate field of knowledge, emerging from its roots in medicine and natural history. In the early 20th century, the rediscovery of Mendel's work led to the rapid development of genetics. Today, biology research is interlaced with all other branches of science and mathematics.
