Talk description: The standard view of evolution is that complex living things arise through gradual refinements of simpler precursors; each successive version becoming better adapted through natural selection, leading to exquisitely refined, complex mechanisms.  But there is another route for life to evolve complexity. Rather than being fine-tuned creations of natural selection, complex features can arise simply because biology is messy and noisy.  In this talk, Professor Jonathan Pettitt will explain how living systems tend to make simple mechanisms more complicated than they need to be. He will show how such ‘unnecessary complexity’ can both restrict and expand an organism’s evolutionary potential.
