Tarsier paper and cover photo in Proceedings od the Royal Society

Melin et al., in this issue of Proceedings B (http://dx.doi.org/10.1098/rspb.2013.0189), raises the possibility that such conditions favoured the evolution of enlarged eyes and high-acuity trichromatic vision in the last common ancestor of crown tarsiers, a concept that challenges prevailing views on the adaptive origins of anthropoid primates.
