You know the old idea that dogs see only in shades of gray?
Studies have shown that’s not true. Dogs do see some colors, though their color vision doesn’t reveal a world as richly or intensely colored as the world we see. Now a new study by scientists, published this month in the peer-reviewed journal Proceedings of the National Academy of Sciences, shows that our human color vision can’t compete with that of wild hummingbirds. These fleet little birds perceive a world far more richly hued than ours, full of visual cues humans never notice, via colors we can’t imaguine. In fact, said evolutionary biologist Mary (Cassie) Stoddard at Princeton:
Humans are color-blind compared to birds and many other animals.Recommend0 recommendationsPublished in
