👉 Crenology is a field of biology that studies the development, evolution, and behavior of sexually reproducing animals. It focuses on understanding how organisms develop from eggs to adulthood and how these changes are reflected in their morphology and behavior. Crenology can be divided into two main branches: embryonic crenology, which deals with the early stages of an organism's life cycle, and postembryonic crenology, which studies the development of a specific organ or system within an animal.
