Keeping an eye on evolution

Physorg.com: "Professor Shaun Collin, from UQ's School of Biomedical Sciences, together with colleagues from the Australian National University and the University of Pennsylvania, have identified animals that have eyes that bridge the evolutionary link between those designed to simply differentiate light from dark to those that possess a camera-like eye. Professor Collin said his research gathered evidence from multiple branches of biology, in support of a gradual evolution of the eye, and it proposes an explicit scenario to explain how it was that our eye emerged.
