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.

While unregistered users are able to browse the forum on a basic level, registering an account provides additional forum access not visible to guests as well as the ability to join in discussions and contribute yourself! Registration is free and instantaneous.

The fungus that infected Permian therapsids wasn't a regular fungal pathogen, but a zombie-state causing fungus akin to the fictional Cordyceps species from The Last of Us.

Bacteria are actually extremely derived posthumans from the future.

There are no transitional pterosaurs. 220 million years ago, alien biology undergrads were fucking around to see if they could get an archosaur to fly, then let their creations loose again for shits and giggles.

Insects are extremely polyphyletic.

Bristletails evolved from krill
Silverfish from myriapods
Cockroaches from isopods
Odonatans and mayflies from unknown crustaceans
Webspinners from spiders
Beetles from horseshoe crabs

And so on...

Projects
Punga: A terraformed world with no vertebrates
Last one crawling: The last arthropod

ARTH-6810: A world without vertebrates (It's ded, but you can still read I guess)

Potential ideas-
Swamp world: A world covered in lakes, with the largest being caspian sized.
Nematozoic: After a mass extinction of ultimate proportions, a single species of nematode is the only surviving animal.
Tri-devonian: A devonian like ecosystem with holocene species on three different continents.

Spiders actually are insects after all.

And rhinoceros, sharks and tuatara really are dinosaurs. All pre-Triassic "sharks" are just ratfish.

Stegosaurus' plates were actually tiny wings that allowed it to fly by flapping them really, really fast.

Not only is Troodon valid, all maniraptors are descend from it

Arthropods are just post-humans from the far future

So called reptiles are just hyper derived HeLa cells send to the past from 3 billion years in the future

Lungfish are actinopterygins

Dinosaurs never existed, but it's not actually a conspiracy by scientists. Alien smugglers actually manufactured the "bones" to conceal drugs and sneak them onto planets under the guise of being hunting trophies.

Megalania was actually just a very large Komodo dragon which was enabled to grow to larger sizes by an abundance of prey.

Viruses are actually posthumans, and the viral parts of our genomes are not from past viral infections but are in fact the only human genetic material that will survive in some future viruses.

Chilesaurus isn't really a dinosaur, but instead is a late-surviving shuvosaur.

Sauropods aren't dinosaurs at all but they are late surviving descendants of Odontochelys that have become much more highly complex and evolved convergently similar to giraffes and elephants but the prosauropods are actually highly-derived late- surviving descendants of Euparkeria.
Discontinued projects:
The New Ostracoderms (i might continue with this project again someday)
The Americas (where in 58 million years from now in the future North and South America has both become isolated island continents)

We are all actually just sapient troodontids living in a full-immersion VR MMO of a speculative future where the dinosaurs were wiped out by a meteor, and I've been playing so long I've completely forgotten about my troodontid life and how to leave the simulation. Please help me get out.
