Eyes: How Evolution Learned to See is a 3D virtual gallery on MyGallery3D, a walkable online exhibition of 16 works. Step inside and explore it in your browser: no app, no headset.
This is a 3D virtual gallery of eyes, and you walk through it in your browser: ten fundamentally different ways an animal can turn light into an image.
Darwin admitted the eye seemed "absurd in the highest possible degree" as a product of natural selection. Then he explained why it was not. Eyespots have evolved independently somewhere between 40 and 65 times, and a model using deliberately pessimistic numbers found that a flat patch of photoreceptor cells could become a full vertebrate eye in under 364,000 years. Some jellyfish have elaborate eyes and no brain at all.
The oldest certain fossilised eye comes from a Schmidtiellus reetae fossil, 530 million years old, collected at Saviranna in northern Estonia. It carried around 100 ommatidia, spaced further apart than a modern dragonfly's, and no lens at all. Trilobite eyes were stranger still: clear calcite crystals formed their lenses, unlike most other arthropods, which have soft eyes.
A compound eye is a bundle of ommatidia, each with its own lens, pointing in slightly different directions. Some carry up to 28,000 of them and see a full 360 degrees. The trade is resolution: physics stops a compound eye from resolving better than 1 degree. What it gains is speed. A honey bee registers a change in light in 0.01 seconds, where a human takes 0.05.
Every technological method humans commonly use to capture an optical image already occurs in nature, with two exceptions: zoom and Fresnel lenses. The scallop Pecten fringes the edge of its shell with up to 100 reflector eyes, each focusing with mirrors rather than a lens. The spookfish uses a curved mirror of stacked guanine crystals to catch light from below while a lens handles the light from above.
