* can only distinguish light from dark.
* causes small, round spots with a brown border surrounded by a a yellow halo.
* consists of a photoreceptor protein which absorbs light energy.
* occurs in cool, moist climates where fall-sown cereals predominate.
* present in adults are functionless.
+ Evolution of the eye, Early stages of eye evolution: Eye :: Evolutionary biology
  * The earliest light sensors were photoreceptor proteins. They are eyespots, found in protists. Eyespots can only distinguish light from dark. This is enough for photoperiodism and daily synchronization of circadian rhythms. They cannot distinguish shapes or determine the direction light is coming from.
  * Eyespots are found in nearly all major animal groups. The 'Euglena's eyespot, called a 'stigma', is at the front. Its red pigment shades a collection of light sensitive crystals. Together with the leading flagellum, the eyespot allows the organism to move in response to light to assist in photosynthesis, and to predict day and night, the primary function of circadian rhythms.
