Re: Question for Arach or anyone
let's not forget that all mammals evolved from reptiles and we, for the most part don't have great colour vision, most mammals have very good night-vision, which automatically rules out colour vision (we have specific cells in our eyes, on lot for colour vision, one lot for night vision) the primates evolved colour vision to detect ripened fruit, it is possible birds evolved good colour vision for similar reasons early in their ancestory
