Fly eye and Penrose 11

Fly eye and Penrose 11

A play on light and form,

This is a microscopic image of an eye cross-section… Not an eye like ours, with a single lens, the crystalline that concentrates light on our retina. No, a compound eye of thousands of tiny facets, each comprising a miniscule lens… A Drosophila eye, the eye of the fruit fly.

So different from our own. And yet, the gene used by Drosophila embryos in the assembly of their eyes is so very close to the gene that we use in the construction of ours. To such an extent that if we artificially replace its eye gene with our own, our gene allows the tiny fly to construct this eye with a thousand lenses…

And here, a work by the mathematician Casselmann : Penrose 11. Variations on geometric patterns. Shifting. Relating. Passing through one form into another. An abstract illustration that evokes the wealth of variation that genealogy has produced on a single theme, over the long history of the evolution of life.
