evolution of color vision

The evolution of color vision in primates is unique among most eutherian mammals.

The decline in the sense of smell may not be the direct result of the evolution of color vision, the Leipzig researchers say, but the two factors do seem to be related.

Casagrande, V.A., I. Khaytin, and J. Boyd (2007) What the evolution of color vision tells us about the function of parallel visual pathways in primates.

The fact that those with the most advanced vision also are the species with the most colourful bodies suggests the evolution of colour vision has taken the same direction as the peacock's tail.

Not only do scientists study the sifaka to get insight of evolution but they have also been the subject of those researching evolution of color vision, paternal care, matriarchal primate societies and causes of speciation.

The color vision priority hypothesis states that the evolution of color vision in primates may have decreased primate reliance on olfaction, which explains the relaxation of selective pressure that accounts for the accumulation of olfactory receptor pseudogenes in primates.
