During the year ending September 2007 UCSC added eight new organisms to the GBD: lizard (A. carolinensis), horse, platypus, medaka, stickleback and three worms (Caenorhabditis brenneri, C. remanei and Pristionchus pacificus). Nine existing organisms were updated with new assemblies: mouse, cow, cat, fugu, zebrafish, Drosophila melanogaster, two worms (C. elegans, C. briggsae) and sea urchin. As updates are added, older assemblies remain accessible either on the primary website or through the GBD archives.
