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.

A another less serious scifi sorta of thing I did awhile back.

Grays (2007)

The Grays are real, but not from another planet. They are indeed from Earth and are multiverse travelers. They happen to live in a timeline where dinosaurs never died out. But they enjoy visiting our alternate timeline in which humans live and abducted them in their multiversal ships. Their testing base happened to be in the location on their Earth where Roswell, NM is on our Earth. Thus the 1947 crash was indeed their 1st attempt at multiverse travel that went extremely wrong. Earth's governments are helpless to these invaders since their technology far exceeds our own. We are merely lab rats in the eyes of the Grays.

Their culture is is very strange in comparison to humans. They not only do not care to wear clothing but are completely carnivorous. However they are not savage. They will raise small mammals for meat and egg laying dinosaurs for eggs. They are very inquisitive and love to figure out things. Their large skulls support a brain larger than humans. Their huge eyes can see in the dark very well. This is important since they are nocturnal. This is one reason why abduction happen mostly at night.

They have feathers like birds and are warm blooded. They lay eggs and put them in incubators. Females run things in society since they are bigger and more aggressive. The males are more colorful with bright blue feathers. They even do odd mating rituals like birds would with chirps and puffing out their chests.

Since their eyes are different from humans they use a neutralizer to wipe the minds of their subjects. They tend to look down at mammals and think they are inferior since they tend to eat their relatives for lunch. They also enjoy abducting livestock for an exotic snack.

As you can see they evolved from the raptor dinosaurs, specifically the Troodon. They lost most of their tail and snout but still have some claws even thought they are not used too much. They still have sharp teeth and have a huge brain. Their bones are quite brittle since they were once agile hunters. They still have the agility but must make sure they do not get hurt and break a bone.

When they make sounds they can make hypersonic sounds that humans cannot hear. This makes it seem like they are communicating via telepathy but really they are not. In short they are not little green men in the UFOs it is little gray dinosaurs!

Evolution of the Grays (2005)

I know this is very implausible but I thought i would share it just the same.

Here were a couple species I made a long time ago where the Arctic had melted and the new species evolved. It was not taken very seriously but some fun drawing. Just though i would share something not Sagan 4 with you.

Walurus (2005)
Its a fully aquatic polar bear that evolves after the ice caps have melted away.

Posted Image
Sea Foxter (2013)
The Sea Foxter is a future evolution of the Arctic Fox after the ice of the North Pole melts. They have adapted a sea otter like body with thick layers of fur. Its coloring is dark like the summer Arctic Fox. Without ice and snow it doesn't need a white coat anymore. It is mainly a scavenger who follows the Walursus (a future polar bear). It nibbles up the floating scraps that the Walursus leaves behind. They still come to land to make dens and raise their pups. Their acute sense of smell allows them to find a floating kill from miles away. They are opportunists so they will also scavenge on land if the opportunity presents itself. However with human encroachment most land kills are road kills.

Brachoose (2007)
If a Canadian Goose evolved into a Brachiosaurs-like creature. This one is less serious. I just think it looks cool.

An arboreal, nocturnal relative of crocodiles of Australia from the Pleistocene, such as Quinkana. Being the apex predator of its environment, it has no need for armor, and has smoother, less protected skin, so it can change its skin color depending on its environment and mood. A grasping appendage at the end of the tail helps to climb, while sickle claws also aid in clinging to branches.

I was recently thinking back to my old project Janus , and how to deal with some of the issues raised with biradial symmetry, in particular, oceanic and marine life. Tails obviously couldn't work, so I was originally thinking fins. However, I have a new idea I want to run by to check the plausibility: Jet propulsion lungs (well, really just gills but they later become lungs). The animal sucks in water into a central gill/lung, where it's then propelled out of the mouth to speed it along.
Non Enim Cadunt!

No idea how to actually hold down a project.

I was imagining kangaroo's coming to inhabit some form of large grassland and assuming the role as large grazers.

I like the idea behind it, as it seems plausible to me, but I feel like it if it were to become some sort of grazer it would probably have a less saturated color scheme, maybe something like a more brown or gray sort of coloration resembling other mammalian grazers.

flightless ratite like herbivorous pterosaurs they have developed long powerful hind legs adapted in much the same way as a ratite and one of there toes has adapted into a deadly sharp claw much like a cassowary and the other 2 toes of there once five toed feet becoming dewclaws. there wings once adapted for flight have become small mostly used for elaborate display or to frighten predators via spreading there wings and flushing them with blood to make them brightly colored and reveal a prominent eye spot. as for why they exist they come from a world where ratites never evolved and a single small species of pterosaur made it through the k pg extinction and to avoid competition with the more numerous and arguably better flight adapted birds became flightless.

A rather muscular ape descendant who has taken to a savannah like biome where no other predators are present, allowing them to fill the niche. They'd have a tawny colour and would ambush prey, before quickly snapping their neck as a killing method. I've always wanted to have a predator that kills by this method and nothing terrifies me more than a massive camoflauged gorilla snapping the necks of some poor zebra analogue.
Projects Currently Being Worked Upon:

Karkinos: Where faith meets myth on a world of the strangely familiar.
Under New Suns: The forums own colonisation race! Steep yourself in my lore....

Projects in suspension (for when inspiration hits):

- Galapagaia
- Rich Man's Ark (nice little bit of community spec :P)
- Ichor

Projects for a latter day:

makes sense to me - lots of mammalian herbivores outside of Australia are red-colored to camoflage with teh greenstuffs, thanks to the colorblindness of their predators

Deer die out, and goats become the new dominant deer-type fauna. It's essentially deer, but they got creepy goat eyes.

Don't forget horns, deer got antlers that fall off each year, while goats have horns that stay all year round.

How do deer got die out? And are goats you thinking about domestic or wild caprids?

Like the idea, planed something similar, but chose to keep deers.
Projects (they are not dead, just updated realy slowly, feel free to comment):
-World after plague After a horrible plague unleashed by man nature slowly recovers. Now 36 million years later we take a look at this weird and wonderful world.
-Galaxy on fire. They have left their home to get out of war. They had no idea what awaits them.

Here's an idea I have for The Speculative Dinosaur Project

A Pygmy Stegosaur that lives on an island in Asia (Like The Andaman Islands)
My sporadically updated Youtube page

Do you get it? I hardly ever come here so I'm like something a cryptozoologist would study

How about a plant that builds a structure out of sand grains and resin that surrounds its roots to protect from burrowing animals. It eventually evolves to retract its stem into the shell when it is touched, other species evolve an entirely mineralized skeleton
