A depiction of the history and relationships over diverse species born throughout time
This center of the fan denotes the birth of life on earth 3.8 billion years ago. Since that time, evolution has given rise to diverse species, and edges of the fan represent the limits of the living world in the present day. The many milestone events of biological history, including the emergence of eukaryotes, the advent of multicellular life, the transition of marine life to terrestrial habitats, and species explosions, can be read as an exciting and dramatic story. This project is an attempt to show how each species is positioned in that history and how species relate to each other. As can be seen from our position within the fan, we humans are also part of the same biohistory that began 3.8 billion years ago.
