A clear, molecular view of how human color vision evolved
Many genetic mutations in visual pigments, spread over millions of years, were required for humans to evolve from a primitive mammal with a dim, shadowy view of the world into a greater ape able to see all the colors in a rainbow. Now, after more than two decades of painstaking research, scientists have finished a detailed and complete picture of the evolution of human color vision.<img src="//feeds.feedburner.com/~r/sciencedaily/~4/36Pi0TMimXw" height="1" width="1" alt=""/>
