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.

Regular Forum Snaiad
Snaiad is one of Humanity's first off-world colonies, the jewel in the sky, the realm of the sublime. The hopeful colonists arriving from the war-weary Mediterranean found themselves not in a second Garden of Eden, but an unusual new world they had to understand and adapt in order to survive. Understand it they did, and here is what they found. Discuss.
