These images are created by millions of living, single-celled, aquatic organisms as they carry out photosynthesis. Photographic negatives are placed in front of Euglena gracilis and they are drawn towards the varying degrees of light passing through the negatives. In turn, they create haunting, temporary images. By working with these primitive life forms, my work explores Darwin’s ideas about our origins and evolution. Many of the artworks are named after lines from The Origin of Species. I also highlight an ecological system in which we depend on such life forms for most of our oxygen.
