摘要：

The skin of many animals includes cells that respond to light by dispersing or aggregating granules within them. A study of such cells in frog skin now delivers the finding that they express a molecule, melanopsin, which is similar to the light-sensitive rhodopsins in eyes. In itself, that is not surprising. What is unexpected is that melanopsin is more closely related to invertebrate than to vertebrate rhodopsins, including that in the frog's own eyes. In evolutionary terms, then, this observation throws up all sorts of tantalizing questions.
