The effects of natural selection are ultimately mediated through protein function. The traditional view that selection on proteins is primarily due to the effects of mutations on protein structure has however in recent years been replaced by a much richer picture. This modern perspective was in evidence at a recent meeting on protein evolution in Hinxton UK. Here we report some of the highlights. Unsurprisingly Charles Darwin featured at lot at the meeting. Evolutionary arguments are all-pervasive in the biomedical and life sciences and this is particularly true for the analysis of proteins and their role in cell and molecular biology. From initial investigations of individual proteins in the 1940s and 1950s which were motivated by even earlier work on blood groups we can now routinely collect information from a large number of sequenced genomes to help us understand the evolution of proteins in terms of their sequences structures and functions and their roles as parts of biological systems. Comparative evolution The primacy of comparative and thus evolutionary arguments in the analysis of proteins and their structure was emphasized by Tom Blundell University of Cambridge UK who reviewed almost 40 years of structural bioinformatics. He noted that in the early studies of insulin structure the common ancestry of all life on .
