Perceiving Light – the trickiest biological application on Earth

International Year of Light Blog

One of the most important abilities developed by living organisms on Earth is adaptation to the light that comes from the nearest star in our galaxy – the Sun. This ability is called light perception. Interestingly, it defines not only the perception of a source of light, but the perception of all surrounding reality! It determines colors, shapes, orientation in space and in time.
