Complexity and life

During the last two decades, a new understanding of life emerged at the forefront of science. The development of complexity theory, technically known as nonlinear dynamics, has allowed scientists and mathematicians to model the complexities of living systems in new ways that have yielded many important discoveries. In this article, the author reviews the basic concepts, current achievements and status of complexity theory from the perspective of the new understanding of biological life. Models and theories discussed include the theory of dissipative structures for nonlinear chemical systems, the application of bifurcation theory to genetic networks and cell differentiation, the study of the origin of biological form (morphology), a new approach to the understanding of developmental stability in embryology., and a model of the 'origin of life' and prebiotic evolution in tiny, membrane-bounded vesicles in the primeval oceans.
