Convergence introduces Darwin to Plato

The phenomenon of convergence has been recognised in external morphology (e.g. the streamlined shape of sharks and porpoises), structural detail (e.g. the camera-like construction of the vertebrate eye and the octopus eye), and in many other functional aspects of organisms (e.g. the echolocation systems used by bats and whales). In textbooks and popular science writing, convergence is often explained in a Darwinian way, invoking the amazing powers of natural selection. However, far from being a curiosity that pops up from time to time, convergence appears to be a pervasive feature of the living world. Championing this perspective is Professor Simon Conway Morris, an evolutionary palaeontologist from Cambridge University, who is actively contributing to debate and constructing an online database of specific examples.
