Evolution and immunity.

This report describes a meeting organized by Ken Smith and Jim Kaufman, entitled Evolution and Immunity, which took place at the University of Cambridge on 24 September 2009 to honour the anniversaries of the birth of Darwin and the first publication of The Origin of Species. Ten internationally-known speakers described the effects of evolution on immunity, ranging in timescales from the deep-time evolution of adaptive immune systems in vertebrates and invertebrates to the evolution of pathogens and lymphocytes within a single individual. The final talk explored the application of phylogenetic analysis to non-biological systems.
