Geoffrey West on Complex Biological Networks

Geoffrey West is a professor and past president of the Santa Fe Institute. He is a high energy physicist turned quantitative biologist who works on complex networks. In this very interesting conversation (see link below), which is a part of Cambridge Nights Series, he talks about amazingly simple scaling behavior seen in all species, including trees, which gives predictive power to the biological systems. For example, for a given mass of the species one can predict how long it is going to live, based on scaling behavior of metabolic rates with mass. I was always interested in learning more about the quantitative nature of the biological mechanisms, because there is a generic underlying physical phenomena at work for any biological system, and there must be a way to understand and predict the evolution of these systems based on these phenomena.

Similar talks can be found here and here, where he talks about surprising discovery of this kind of scaling behavior when applied to evolution of cities and companies.
