| Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike.

Obey or I'll send you to the moon

In this world, Earth is inhabited by humans for the next 5 million years, until they finally leave. Even though they have found out how not to harm nature, a mass extinction has occurred, and animals that are Extinct in the Wild have not been released back into the wild of Earth. Plus evolution has been slow as we have not allowed any mutants that have occurred to breed. Here we jump forward to year 25 million, where we will be looking at life. Also I would like to do 100 million years in the future and 200 million years. World in 25 million years: California has separated and drifted north west, and is covered in lush forests. North America has separated from South America (though not by much) and moved slightly North, causing huge taiga in the North, forests around the current U.S.-Canadian border and around the coasts, huge prairie in the center, in Central America is a rainforest, and the south-eastern corner of the U.S. (around Florida to Louisiana, north to Southern Missouri (due to Mississippi river) and north to South Carolina) is a huge swamp from the slightly higher ocean level (due to more ice melted in Antarctica than frozen in Greenland). South America has drifted slightly northward, causing the entire Northern 2/3 to be covered in rain forest, and the southern third to be covered in savannah. Antarctica has drifted north too, and the southern half is covered in ice sheets, while the northern half covered in tundra savannah (coniferous trees). This has caused unique fauna to evolve in Antarctica. Africa has crashed into Gilbratar, blocking off the Mediterranean and causing it to dry out, forming a huge salt desert. The northern half of Africa is dry savannah with Acaica plants littering the landscape, similar to todays African Savannah. Europe’s western and northern side is covered in forest, the southeastern side is covered in prairie. Asia is covered in rain forest to the south-east, the center of Asia in a huge strip is covered in forest, and now-Russia is covered in taiga. There is also a huge desert in the area of the Gobi desert today. Australia has moved northward to the equator and crashed into Papua New Guinea, it is now covered in rain forest everywhere except for the central savannah, not too different from Africa’s savannah. Africa east of the Nile has broken off and formed East Africa (AKA Lemuria) and is covered in rain-forests. Madagascar has drifted farther from Africa, and is still covered in rain forest. The primary herbivores are lemurs, the primary carnivores are tenrecs, which are very diverse, resembling hedgehogs, otters, weasels, rats, etc... Greenland has become bigger by way of the Canadian isles, and has moved northward to become an Australia-sized north pole Antarctica, effectively keeping the sea level at about the same level. There is also approximately 30% oxygen content in the air from the extra plants in Antarctica, allowing arthropods to become 150% bigger (15 inches big approx), and bigger chordate limit. You can call the habitats by these names. Antarctic savannah tundra. South American savannah/rain forest. North American grassland plains/forest/Central American rain forest/taiga/swamp. Californian forest. West African rain forest/savannah. East African rain forest. Madagascar rain forest. Australian rain forest/savannah. European forest/grassland plains/Mediterranean desert. Asian desert/forest/rain forest/taiga. To name an animal, putting in the begging (name)/(ancestor)/(scientific name, if any)/(habitat) would be nice. I'll put a survivor list, then creatures I created soon. I'll also attach an early draft of it I made, but you need Pages (Mac OS X only) or possibly OpenOffice to open it.

Nice concepts. And no, the atmosphere didn't matter, since even the largest pterosaurs could fly nowadays.
There's the whole Middle Cretaceous Crisis thing, and that, alongside the progressively poorer fossil record towards the end of the Cretaceous, would explain pterosaur absence, not avian diversity. Also the discovery of a smaller azhdarchid species with a different beak on the same territory as Quetzalcoatlus suggests at least azhdarchids were more diverse than previously thought. Anyway, back to the topic |

Well, you're the pterosaur expert. Could there be a feathered descendant of porcupines? Feathers are basically thick hairs with branching hairs, the porcupine spines are basically thick hairs, so all they need is branching structures coming out from it and the spines to lose some of its density. |

Could be, though there wouldn't be any use for them, since they wouldn't be doing any flying any time due to how heavy and ungraceful they are |

But the theropods (and possibly their lizard ancestors) had feathers and couldn't fly. So why couldn't a porcupine evolve feathers? |

I have the 2nd and last batch of creatures. Megaduck:  Here is a bigger picture of the Megaduck Mersnail:  Here is a bigger picture of the Mersnail Platyraffe: Platyraffe/Platypus/Australian Savannah: A 10 foot tall herbivorous giraffe-like descendant of the platypus.  Here is a bigger picture of the Platyraffe Ratanteater:  Here is a bigger picture of the Ratanteater Seaguana:  Here is a bigger picture of the Seaguana Terror Bill: Terror Bill/Platypus/African Savanna: A carnivorous platypus. They have developed teeth-like structures on its bill to kill and eat.  Here is a bigger picture of the Terror Bill Terrowl:  Here is a bigger picture of the Terrowl Theriumonitor:  Here is a bigger picture of the Theriumonitor Trapjelly:  Here is a bigger picture of the Trapjelly And finally, the Tree Octopus:  And here is a bigger picture of the Tree Octopus Hope you like it! |

I'm not saying theey couldn't, it'd just be unpratical for a large rodent like a porcupine |

Well, it could be an adaption that porcupines evolve to protect against the next ice age in around 6-8 million years. Afterward the porcupines just got a thinner coat. |

i think that platypus are unreal,because they have got reduced teeth(i can describe it more,but in english is that very hard for me ) more possible is marine platypus,that eath shrimps and snails or doplhin like platypus(but there is problem with milk) |

Actually I wanted the teeth to be coming from the bill instead of being teeth. The platypus has horny plates on its bill which can turn into something like teeth. Also, the babies do have an egg tooth, so that could turn into real teeth. |

I have 5 more species, all for the Canadian taiga. Coywolf/Coyote/North American Taiga: A gray with brown bottom 5-6.5 foot long woolly coyote. It lives in packs of 10-20 individuals and has a bigger head and snout. Coybear/Coyote/North American Taiga: A bear-like woolly dark brown, gray, or black coyote with saber teeth. It is 6-10 feet long, depending on species. Megadeer/White Tailed Deer/North American Taiga: A 15 foot tall long necked deer. Other than its size and neck it looks exactly like a white tailed deer. Megagoose/Canadian Goose/North American Taiga: A 10 foot tall black goose. Its shape is like a Canadian goose except the legs are 2x as long. Smilofus/Bobcat/North American Taiga: A 7 foot long saber-toothed bobcat. It looks exactly the same. It is brown-gray with spots on the legs and head. There is also the arctic rabbideer from the first page. |

Well, lynx partially rules the European forest, but I haven't done anything for Asia yet. I just don't know its fauna. In case any of you were wondering, I will not do any descendants of domesticated animals or GE animals. Could there be a group of bipedal herbivores/omnivores/carnivores similar to Metazoicas therapeds? I could see them being evolved from elephant shrews like in Metazoica which will place them in Africa, kangaroo rats which will place them in North America, jerboas which will place them in Africa or Asia (can be an alternative for a eutherian kangaroo), or hopping mice which will place them in Australia (but I doubt that they would due to competition of macropods). Also, what do you think of my ground sloth-like descendant of South American monkeys? |

elephant shrews-i think that is more possible to evolved into leptictidium like animals,or small pig/antelope like forest herbivores hopping mice in australia-there are kangaroos,hopping mice have no chance |

Actually I think that elephant shrews are at the stage that dinosaurs were when bipedalism was starting to evolve. If its true, then elephant shrews can definitely become theropod-shaped. As for my ground sloth primate, all primates have at least limited bipedalism. So ground sloth primates are possible. |
