This important introduction to theoretical biology is a classic work in its field. Already in the 1930's Bertalanffy formulated the organismic system theory that later became the kernel of the GST (General Systems Theory]. GST is an interdisciplinary practice that describes systems with interacting components, applicable to biology, cybernetics, and other fields.

His mathematical model of an organism's growth over time is still in use today.
