- 1. Theoretical biology is an interdisciplinary field that applies mathematical and computational tools to study biological systems and processes. It aims to develop theoretical models and frameworks to understand complex biological phenomena, such as the dynamics of ecosystems, the behavior of cells, and the evolution of species. By using mathematical models, theoretical biologists can make predictions, test hypotheses, and gain insights into the underlying principles that govern living organisms. This field plays a crucial role in advancing our understanding of biology and has applications in a wide range of areas, including genetics, ecology, and medicine.
