Does symmetry arise from the algorithmic nature of evolution?

Prof. Dr. Ard Louis, (Rudolf Peierls Centre for Theoretical Physics, University of Oxford, U.K.)

The natural world is full of symmetries. Do these arise because natural selection favours symmetry, or could they arise for other reasons? By applying the coding theorem from algorithmic information theory to models of evolution we argue that random mutations are re exponentially more likely to generate phenotypic variation that has low algorithmic complexity than variation that has higher complexity. We find evidence for this exponential scaling in protein quaternary structures, RNA secondary structures, and gene regulatory networks. Rather than being favoured by natural selection, simpler and therefore more symmetric phenotypes emerge because they are easier to discover in evolutionary search.
