Abstract excerpt

Humans and other Old World primates (Catarrhini) share very similar L (long-wavelength, 'red') and M (medium-wavelength, 'green') cone photopigment spectral sensitivities, with peaks at around 563 nm and 535 nm, respectively. Changes of single amino acid residues at critical sites in photopigment...
