Reports from Duke University describe recent advances in theoretical biology
October 9th, 2008
"Robustness to mutations and noise has been shown to evolve through stabilizing selection for optimal phenotypes in model gene regulatory networks. The ability to evolve robust mutants is known to depend on the network architecture," scientists in the United States report. "How do the dynamical properties and state-space structures of networks with high and low robustness differ' Does selection operate on the global dynamical behavior of the networks' What kind of state-space structures are favored by selection' We provide damage propagation analysis and an extensive statistical analysis of state spaces of these model networks to show that the change in their dynamical...
