Evolutionary replacement of UV vision by violet vision in fish.

Proceedings of the National Academy of Sciences of the United States of America - 13 Oct 2009

Tada Takashi, Altun Ahmet, Yokoyama Shozo

Abstract excerpt

The vertebrate ancestor possessed ultraviolet (UV) vision and many species have retained it during evolution. Many other species switched to violet vision and, then again, some avian species switched back to UV vision. These UV and violet vision are mediated by short wavelength-sensitive (SWS1) pigments that absorb light maximally (lambda(max)) at approximately 360 and 390-440 nm, respectively. It is not well...
