The tree of life might seem like a stable design, appropriate for indelible ink. Plenty of people think so. An Internet search for “phylogenetic tattoos” turns up some showy skin art. But the branches are shifting. Since a radial diagram based on 1990s genetics inspired a rush for tree-of-life tattoos, technical diagrams of life’s ancestral connections have been redrawn. When Patrick Keeling at the University of British Columbia in Vancouver unveils a working scientist’s current diagram for his students, most have never heard the names of the major branches. In the new vision — based on increasingly sophisticated genetic analyses — people and other animals are closer cousins to single-celled choanoflagellates than to other multicellular organisms.
Genetics-based versions of the treetop of life have inspired a new genre of tattoo, often with symbolic organisms rather than multisyllabic labels. Science Ink: Tattoos of the Science Obsessed, Carl Zimmer (Sterling). © 2011 Carl Zimmer. Tree thinking qz.
