Does this explain why, at night, every car with a roof rack is the police?

Mostly primates, and they are mostly dichromats, but it certainly doesn't belong to only human mammals 2) Hundreds of other animals (non-mammals) have color vision, many much better than we do, including fish and birds with tetrachromacy (four cone cells) and butterflies with up to six unique cone cells 3) Did all these insects, fish and birds with extremely good color vision evolve it just to read each other's emotions? I'd love to see a bee blush... Can the scientist think of no other reason why the ability to see red might be selected for..? The article is interesting, but I have no idea what is up with this rot:
