On a steep, narrow street above Chinatown works Jonathon Keats, a tweed-suited, bow-tied 32-year-old who, with assistance from a phalanx of scientists, is genetically engineering God in his apartment. Advisers to Keats’ organization, the International Association for Divine Taxonomy, include biochemists, biophysicists, ecologists, geneticists and zoologists from the University of California at Berkeley, the Smithsonian and other institutions of scientific repute. The mission: to determine where on the phylogenetic map -- the scientific tree of life -- to put God.
