The vision system used to process color is separate from that used to detect motion, according to a new study by researchers at New York University's Center for Developmental Genetics and in the Department of Genetics and Neurobiology at Germany's University of Wrzburg. The findings, which appear in the latest issue of the Proceedings of the National Academy of Sciences, run counter to previous scholarship that suggested motion detection and color contrast may work in tandem.The study's...

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...

Vision, like other biological attributes, is shaped by evolution through environmental pressures and demands, and even closely-related species that are in other ways very similar might respond to their particular environments by interpreting the visual world slightly differently, using photoreceptors that are attuned to particular wavelengths of light. By studying a special group of closely-related fish species inhabiting the Great Lakes of Africa, researchers have uncovered clues to...
