Evolution of the eye, artwork
Evolution of the eye, computer artwork. It is thought that the eye originated as a patch of light-sensitive cells (left) on the organisms surface. When a mutation in some organisms led to the cells being positioned in a small depression, it became possible to detect the direction of the light source. As the depression became deeper and the aperture narrower (centre), this information became more precise and it was possible to make out shapes. Next a protective layer formed over the opening, allowing cells inside the eye to begin to specialise. Some organisms went on to form lenses at the front of the eye (right), which allowed the eye to focus

EDITORS COMMENTS
This artwork titled "Evolution of the Eye" takes us on a visual journey through the remarkable development of this complex organ. The print showcases the gradual transformation from a simple patch of light-sensitive cells to the intricate structure we know today. On the left side, we witness how these light-sensitive cells initially formed on an organism's surface. However, a fortunate mutation led to their relocation within a small depression, enabling them to detect the direction of light sources. As time passed and evolution took its course, this depression deepened and narrowed in the center image, enhancing precision and allowing for shape recognition. The subsequent formation of a protective layer over this opening marked a crucial milestone as it paved the way for specialized cells inside the eye to emerge. Moving towards the right side of the print, we observe some organisms developing lenses at their front, revolutionizing their ability to focus. With its white background highlighting every intricate detail, this illustration beautifully captures nature's ingenuity in shaping one of our most vital sensory organs. From cutouts depicting various anatomical components like retina, iris, pupil, and optic nerve to terms such as aqueous humor and sclera that hint at its biological complexity – every element contributes to our understanding of ocular evolution. This thought-provoking artwork by Science Photo Library invites us to marvel at how life has evolved over millions of years into beings capable of perceiving shapes and experiencing vision through these incredible eyes.
