Seeing at the Speed of B Not c

Bees see the world almost 5× faster than humans, and this gives bumblebees the fastest colour vision of all animals, allowing them to easily navigate shady bushes to find food, so write researchers Skorupski and Chittka in the Journal of Neuroscience. The ability to see at high speed is common in fast-flying insects; allowing them to escape predators and catch their mates mid-air. However, until now it wasn't known whether the bees' full colour vision was able to keep up with their high speed flight. This research sheds new light on the matter; suggesting that although slower, it is still about twice as fast as human vision. [Source: physorg.com]

✝ We know from another recent post that insect vision emerged later than in vertebrates.
