The blue receptor is the quintessential element in the evolution of color vision, a wonderful new way to see things.
"The study is significant because it... moves beyond the food or sex debate for the evolution of trichromatic vision," says Nathaniel Dominy, a physical anthropologist at the University of California, Santa Cruz.
As it is overall well supported by the data, and in good agreement with previous analyses of different datasets (e.g. [ 41- 43], it is a well founded hypothesis of relationships. Although the tree has some nodes with low posterior probability, only two of these affect the interpretation of the evolution of colour vision (indicated by a and b in Figure 2).
-,, However, our results might provide a framework for speculating about the adaptive value of the evolution of color vision in order to fill a phylogenetic gap from Old World monkeys to humans.
"It contradicts everything we have thought for a century about the evolution of primate vision".
Our findings highlight the importance of the foraging hypothesis but not rule out the potential role of the intraspecific socio-sexual communication and may serve to add useful information to the debate regarding the adaptive value of the evolution of color vision in order to fill a phylogenetic gap from Old World monkeys to humans.
The early evolution of vision is an open question [ 9].
"We're at a historic juncture in the evolution of mobility…Our vision for the future is all encompassing….for all ages, from urban professional to exurban retiree, and from commute-minded to thrill-seeking," said, Harley-Davidson's CEO Matt Levatich on the LiveWire and e-concept releases.
Establishment of an expression system in cultured cells has been a major hurdle in the study of spectral tuning of butterfly photoreceptors, which has become a central topic of the evolution of color vision.
We may get a clearer view of the evolution of colour vision with additional data on SWS2 sensitivities and on ocular transmission, as well as refractive indices in compound lenses.
