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. With a member base comprising users from across the world, our community is the largest and longest-running place of gathering for speculative biologists on the web.

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.

Well, European herbivores are very low, so they could, along with rodents, water deer, muntjac, and possibly rabbits conquer Europe.

Now, what can the 100 MYF amphibious octopi be like?

And what about Pangea II, 200 MYF? There was a decan traps-like extinction in 110 MYF. I'm thinking the kochlidtheria, flying lizards, crocodilians, testudines, deer-lizards, and snakes be rulers, with octopi taking the amphibian niche (amphibians survived the last Pangea, so the amphibious octopi could too), with rabbits and lagmorphs taking the small herbivore niche (with some small armadillos or opposums in ex-South America and small possums in ex-Australia), and birds being extinct. Crocodiles will probably still hold their niche that they've held for millions of years, or they could take the coastal forest predators and the amphibious octopi taking the crocodile niche.

For the desert interior of Pangea II insects and worms could rule, with cockroach descendants being the predators and beetles and ants being the main herbivores.

For the sea the sea snails could still hold the sea niche, sharks also taking the whale niche (cephalopods might retake their present day niche, but sharks still have the dolphin niche), and cnidarians keeping their 100 MYF niche.

For 25 MYF Europe, hedgehogs, wolverines, lynx, and European Baboontherium could rule as predators.

Are the gigant arthropods in the center Pangea II big in size? Because arthropods need lots of oxigen to reach big sizes. And most members in this forum dislike gigant arthropods unless they've got a plausible explanation for that remarcable size.

No, the arthropods are not gigantic size. But the amphibious octopi, kochlidtheres, reptiles, and mammals can't survive the dryness and heat, so arthropods are the biggest lifeforms out there.

And another species for 25 MYF: Jaguarunditherium/Jaguarundi/North American rain forest, southern forest, and swamp: 6-9 feet long gray with spots Jaguarundi descendant. It replaces jaguars in North America. The swamp subspecies have wider webbed feet.

The shark idea, while seeming to borrow from TFIW's sharkopath, does seem likely. That is if they use bioluminescense. If they communicate by projecting a weak electrical field, that's an interesting take.
Actually, I forgot to tell you, sharks are already intelligent. They have been know to play, have problem solving skills, curiosity, and there is a case of 7 great whites working together to bring a partially beached whale to deeper water so they could eat it. So a pack hunting one won't be so far off. Also, as for TFIW, I would say electric fields are better than light as only they are able to sense it, allowing them to sneak up, if they do sneak up.

 I managed to miss all this? :o

Great work.
Terrestrial cephalopods, however...

Good to see creative bcreatures, but the jumping slugs' muscles seem a bit of a problem. How do they work?
Time flows like a river. Which is to say, downhill. We can tell this because everything is going downhill rapidly. It would seem prudent to be somewhere else when we reach the sea.

For the octopus some limbs might fuse to become one foot (I know it's like TFIW, but it's plausible) or possibly super-compact and leg like, allowing them to move at the fastest the speed we can walk. There could also be arboreal ones.

As for the other part, they are snails, and they walk. They also have some sort of endoskeleton.

an ancestor for your fish jellys (?) could be the box jellyfish. It hunts mainly with it's eyes and is arguably the most agile swimmer of all jellyfish being able to make quick turns.
Awesome project by the way.

The box jellyfish could be the group of jellyfish that dominates the see in 100 MYF.

I think I know what to do with the 100 MYF octopus. They fill the arboreal predator niches previously taken by mammals like cats and civets. And with the entire world being rain forest, Mediterranean forest, or swamp, they have water easily. Although they will probably have thick skin so that it's not damaged by the trees.

Also, I've got a large mammal replacement for 100 MYF. It's called the otter deer. It is about 15 feet long, descended from lizards, and replaces large mammals in North America. They have a slender shape, with longer legs that are under them, a long neck, and a long tail. I'll start working on it and try to get it up on DeviantArt today.

 Yep. I knew sharks were intelligent. In fact, when I picked a list of ten animals for my research paper on animal intelligence, sharks were in the list. Very highly intelligent.

The lizardeer is up: Posted Image

Lizardeer/Anole/100 MYF North America: Lizardeers replaced large mammals in North America in 100 MYF, being more successful in the hot world-wide rain forests. They can be from 7 feet long to 40 feet long and a variety of colors.

What kind of animal might come of the treeshrews? Because they seem likely to survive, but I don't know what could come of them in 25 MYF.

Also, could there be omnivorous terror-squirrels? I saw one of the speculative future projects, and the idea was trashed, but squirrels are omnivores and there is a case of squirrels cruelly killing a dog for food, so it's not that far off.
