Are the venom and body enzymes coded for by the same genes ? In this way , the genes could be tinkered with to perfect them for their new role of killing envenomated animals . But researchers sequencing viperid venom genes found just the opposite-that the exons were evolving at a much higher rate . Atop this basic template , nature has wrought complex combinations of ridges and crests , protruding processes and corkscrew tusks to fashion the framework of different species . The sea lions are a mess of overbites and underbites , their crests twisting to the left or the right , the bony protrusions extra large or entirely missing . Genes of all non-bacterial and non-viral organisms are constructed in common fashion , with segments that code for the final protein interspersed with segments that code for nothing . It is the foundation of features that help attract a mate : sexy crests , macho jawlines , demurely dimpled chins . The author and co-author of more than 127 publications in ornithology , he was a prolific scholar . Programs providing credit for similar purposes may be experiencing the same types of collection problems and therefore may seek similar strategies or innovations for contacting borrowers and collecting delinquent debt or other functions , such as disposing of properties acquired through foreclosure . By studying these diverse Alaskan faunas , my colleagues and I are integrating the paleontological histories of the northwestern and northeastern Pacific to form a comprehensive picture of how North Pacific Cenozoic mollusks responded to changes in climate , tectonics and paleogeography . But here at the Academy 's Osher Foundation Laboratory for Molecular Systematics , Robin Lawson and I have begun to sequence venom protein genes in elapids in an effort to find out whether or not they share the viperid pattern of gene duplications and rapid exon evolution .
