Evolution is looking at you


Evolution was at work when eyespots eventually appeared on the wings of butterflies and moths. This trick was so successful, that it was repeated over and over again. Eyespots are a form of mimicry in which a spot on an animal body resembles an eye of a different animal, helping to deceive potential predators. This is evolution following evolution: eyespots developed only when the evolution of eyes themselves was well underway. Depicted is a selection of eye-spotted Lepidoptera. They sit on an ancient oak tree that, as a symbol of the evolutionary tree, was borrowed from Ernst Haeckel, Darwin’s ardent German propagandist.

Natural selection is looking at you


The succession of species, their "blooming" periods and extinctions, puzzled 19th Century naturalists.  Then, Charles Darwin identified natural selection as the key mechanism of evolutionary change. In this  image, Darwin's "fancy" eyes are the eyespots on moth wings that mimic the eyes of predators, an iconic  example of change through natural selection. The bowler hat is a reference to the surrealist painter,  René Magritte, for whom it was a symbol of the bourgeois. Indeed, in the typically narrow mindset of  Darwin’s day, even hinting at procreation was not done. So it certainly marks his genius that he opened  his eyes to the vistas offered by natural selection -- despite his hat..

Windows on Evolution

Charles Darwin, 212 stencil /acrylic  (Din A4)

Science-Art-Nature organises a virtual exhibit “Windows on Evolution: An Artistic Celebration of Chares Darwin”  commemorating coming Darwin Day, February 12, 2013.

I decided to participate in this on-line exhibition. To get in the mood and to kick my entry off,  I made a stencil of the portrait of Charles Darwin, looking through evolutionary eyes. Then I made prints with acrylic spray paint.

 It is is not yet my entry. There is more to come in the near future.
