    and even our brain’s ability to “see into the future” by generating images one-tenth of a second before they actually happen

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

    Am I the only one who didn’t notice the optical illusion in the first four in the slideshow?

    The article is interesting, but I have no idea what is up with this rot:

    For color vision, the cones that we have in our eyes—that [other] mammals don’t—are evolved to see the oxygenation modulations in the blood, because we want to sense the emotions in others.

    1) Plenty of other mammals have color vision. 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..?
