Oh wow, i was doing some research, this could be fun after all. [hider]Over a hundred future animal species are described and illustrated in the book. Major groups include the "rabbucks", versatile descendants of rabbits filling the ecological niches of deer, zebras, giraffes and antelope; "gigantelopes", descendants of antelope filling niches held by elephants, giraffes, moose, musk oxen, rhinoceroses, and other large herbivores; "vortexes" and "porpins", descendants of penguins evolved to fill the aquatic niche of cetaceans; and the predatory rats, the major group of terrestrial predators and descendants of rats. There are also more bizarre creatures such as the "raboons", gigantic theropod-esque descendants of baboons, the "night stalker", a gigantic predatory leaf nosed bat native to Batavia, the "desert leaper", a giant dipodid and the "chiselhead", a descendant of the eastern gray squirrel that has evolved a wormlike shape and large incisors for chiseling into coniferous trees (hence its name).[/hider]
