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.

Why Humans Are Still Here
If humans still had to live like their earliest ancestors, we would not survive at all. We, unlike all other wild animals, do not have teeth or claws as defenses or weapons, we cannot run very fast, we are not as strong as other animals our size, our jaws are weak so we cannot kill or eat our food without specially-made weapons. And we are relatively delicate creatures, much more so than any other mammal our size, our bones are easily broken and our flesh is very easily torn and easy for a predator to bite into. All other prey animals have very tough flesh, are fast-moving, or have some kind of weapons of defense. People do not like to think of their species as being prey for others, but if we were still living in a wild state, we could very easily become targets for all kinds of large predators. Simply put, we would not survive the wild at all. Big predators would eat us into extinction.
Many other hominids have become extinct over the past 2 million years the family has been around. There was even one that was believed to be semi-aquatic and have partially-webbed hands and feet. It was a short-lived, yet crucial, part of our evolutionary outcome. Though we are related to gorillas, orangs and chimps, none of these other closely-related species can swim. Their skeletal structure is too heavy to keep them afloat, and the way the nostrils are placed on the face, water can get into their airway passages and the animals will drown quicker than a human would. It is believed that our nose is shaped the way it is now to help keep out water. Much like the proboscis monkey of Borneo, which is also a semi-aquatic species with a large nose. This could explain our ability to swim, whereas all our other living relatives take pains to avoid the water. This particular species is probably what shaped us into the species we are today.
It could also explain why humans are mostly hairless. Most aquatic mammals are indeed hairless, such as whales, dolphins and manatees. Hair, for the most part, is dead weight in the water. The only fully-aquatic mammal that has put it's fur to good use is the sea otter, and sea otters are relatively slow swimmers compared to seals and dolphins, and mostly just float on the surface of the water. The fur does provide buoyancy, but also keeps a layer of warm air next to the animal's skin to keep them from chilling in the water, especially at night when temperatures drop. But humans evolved in Africa, where it is hot, and it is believed we lost our fur to prevent overheating when we took to the African savannah, where it is much hotter than it is in the jungle where our closest wild kin, the chimpanzees, live. This also aided our semi-aquatic relatives that probably shaped us into the creatures we are now, from becoming waterlogged and drowning. One article I recently read also explains that we may have lost our fur to ward off parasites like ticks and fleas. Many parasite species carry deadly diseases, like plague and lyme disease. If we had fur, parasites would be very hard to spot and brush off since we could not see them in between the hair fibers. So one theory of why we are mostly hairless, whereas other primates aren't, is that it was a defense against parasites.
Somewhere back in our lineage, humans went from a semi-aquatic existence to a fully terrestrial existence. Why? Because the land offered so much more in the way of food for us to take fully to the waters. This is one time evolution took a U-turn. But as a result, we did suffer some problems. Among those is one problem I have been struggling with for several years, FAT!! This is also why we have problems in childbirth, why water births are much easier and less painful than giving birth lying out of water, on our backs. No other mammal feels as much pain in childbirth as we do. Also, because we are naked, we rely on the skins of other animals to keep us warm. Or we build heated structures today to shelter us from the elements. Not exactly what nature intended, but it's a product of our civilizations. We still have hair, it's just not as widesread on our bodies as it is in other land mammals. This also helped in learning to control fire, for heat and cooking, to tenderize our meat. All other living things fear fire and won't go near it, but humans have learned to use it to their advantage, especially today. Everything that made our societies and civilizations is controlled by fire. We use it to burn energy to light and warm our homes, cook, drive to work every day. Everything we are familiar with now is controlled in some way by fire. I say if dinosaurs had learned to exploit fire the way we have, they might still be around today!
Anyone else want to read about Oreopithecus, or the Aquatic Apes we descended from, there is an interesting article that discusses the proof that we did come from this creature. Click on this link to visit the Aquatic Ape Theory.
