April Flowers for redOrbit.com - Your Universe Online A new study, led by Dartmouth College, suggests that primates developed highly accurate, three-color vision that allowed them to shift to daytime living after eons of wandering in the dark. The findings, published in the journal Proceedings of the Royal Society B: Biological Sciences, challenge the prevailing theory that trichromatic color vision, a hallmark event in primate evolution, evolved only after primates became diurnal....

Contrary to the recently established theory that marsupials have excellent color vision, research has shown that the wallaby is a rare exception. The research team, led by Dr Jan Hemmi from the ARC Centre of Excellence in Vision Science and The Australian National University, has shown that Tammar wallabies are much weaker in discriminating different colors because they are missing one type of visual pigment cell. "Dr Ebeling has demonstrated that wallabies do not have the complete set of...

Researchers at the Johns Hopkins School of Medicine and their colleagues have found that mice simply expressing a human light receptor in addition to their own can acquire new color vision, a sign that the brain can adapt far more rapidly to new sensory information than anticipated. This work, appearing March 23 in Science, also suggests that when the first ancestral primate inherited a new type of photoreceptor more than 40 million years ago, it probably experienced immediate color...

WASHINGTON (Reuters) - Primates may have evolved color vision not to find the ripest, tastiest fruit but to detect that tell-tale blush on someone else's rump, U.S. researchers reported on Thursday. The cone structures in the eye that help detect color seem exquisitely tuned to skin tones, the team at the California Institute of Technology reports. "For a hundred years, we've thought that color vision was for finding the right fruit to eat when it was ripe," Mark Changizi, a...
