Welcome to my Metazoic site! This site discusses the existence of the creatures to come along after humans will be extinct. I first became interested in a world after man when I acquired my first copy of Dougal Dixon's After Man: A Zoology of the Future in 1992. However, I unwittingly created creatures that did not exist from the time I was about 8 years old. But it was after I obtained a copy of that book (now a collector's item) that I decided to take these same creatures I created as a child and make them more realistic in an evolutionary sense. Though it may be hard for a lot of us to grasp, humans will soon become extinct. One of the biggest factors of how this will happen is the current overpopulation rate. Which is why I don't contribute to the population. I created this world with little more than mammals fulfilling all ecological niches with the help of some friends. I even gave the era of the age after man a name, I called it the Metazoic, derived from the words for "After-era" (Meta, meaning after, and zoic meaning era). We are now in the Cenozoic era. To view all the animals I have created since I began this project, you can go to the "Meet the Mammals" section of this site. To discuss your own ideas about what you think will happen in the future world, and share your ideas with others, please feel free to leave a comment.
One more thing, some of you may find this site quite offensive, and you have a right to your own opinion. But please respect my right to have an opinion too. I'm not saying there is no GOD, I believe it was HIM who got the ball rolling. But I believe after that, evolution took over. There is so much more evidence of evolution than there is of creation. Even that going on right under our noses. Other than that, enjoy yourself and visit our many links.

More About Bipedalism in Mammals
The first of these is in the book Chasing Kangaroos by Tim Flannery. In it, some scientists did a comparison of energy efficiency of kangaroos compared to quadrupedal animals. In energy efficiency, the kangaroo blew the quadrupedal animal tested out of the water. Another interesting coincidence is found in humankind itself. Among mammals, humans have extraordinary endurance; a fit human can outpace a quarterhorse!
The second one shows how dinosaur-style bipedal gaits are better than erect gaits. Among mammals, humans are unusually subject to a panoply of back problems. This is because our spinal chords are erect, and so our vertebrae are pressing against one another due to gravity. This leads to bad back, slipped discs, and more. Animals with theropod-style stance, however, such as birds are rarely subject to these problems, because the back is mostly the same as it would be in horizontal position, albeit with less support in the forequarters.
This I believe blows to death the theory that mammals taking on a bipedal gait is impossible and a waste of energy! They require NO energy!! Or less than quadrupeds! Mammal bones are also heavier in proportion to their size than dinosaur bones, so they would benefit better by being theropod-like bipeds than quadrupeds because they would burn less energy. Note what I said about streamlining. And I believe Proletarian was wrong about if mammals took on a bipedal stance they would have to lose and then re-evolve their legs. Did we have to do that to take on a bipedal stance? No, we didn't!
