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.

what if the bolid that hited earth during credacerous will be 12000 meters

the extinct spicies are
-all hemichorodates
-all flower plants(with few exceptions)
-all dinosaurs (with exception of bambiraptor)
-all pterosaurs
-all tailless amphibians
-all rays
-all rays
-all mamals (with exceptions of gondwanatheria,marsupials and eutheria)
-all squamates(with few exceptions)
-all birds (with exceptions of ichtiornis)
-all arachnids(with exceptions of scorpions and spiders)
-all crocodiles

sow wath you think (we speculkate about life on earth 200 milions after this K-T)

My project. It stands for "The Future is Bizarre". Basically, it's my future evolution project, focusing on 15MYF, 100MYF, and 225MYF. At first, I had echinoderms ruling the land in 225MYF. I've edited those out and have replaced them with a strange lizard descendent and saltokochlids (a future evolution of snails).



But enough about my project.

Too many extinctions. What will be left to evolve?

The aquatic one I believe. Cause it happened in animals like sea lions.

But please, please, PLEASE, PLEASE, PLEASE give up on the tripod land descendants! I really don't want to start a war.
Star a war? Wow ... over a fictional project?

It's his vision, and instead of saying implausible, impossible, or that will never happen, how about you show him scenarios where it can happen?

Life is stranger then we think. Some forms that existed in the past were so weird, they would equal alien life. I don't see why can't we help him with this project, by introducing species that are so different then the ones now, one would think he lives in an alien world?

The debate so far wasn't very constructive, only because his ideas do not match what you consider to be "possible" to happen in the future. How can you be so sure? That's why we speculate here, not draw conclusions.

So let's speculate, how can we make those strange life forms possible .... by introducing certain scenarios.

We've got triped birds and starfish ruling the Earth. This doesn't seem like it'll be completely compatible with the parameters of Earthly life.
What if there is a larger, faster predator in the water who drastically outnumbers starfish, and it feeds on them? They would have to evolve quickly or go extinct.

Maybe they can evolve into greater size, and become amphibian maybe? Land and sea dwelling creatures too.

Just throwing some possibilities here.

It's not that these ideas aren't strange. They are. But strange does not equal a good project. It must be strange and plausible. These creatures certainly have the strange part down. But the plausible aspect is still way over their heads.


When it comes to land echinoderms, they would never, ever evolve. And it's not because the haven't yet. Their basic biology does not allow them to. Echinoderms possess a water vascular system, meaning they have to have water CONSTANTLY rushing through their system to perform the basic biological functions, like reproduction, movement, respiration, circulation, digestion.

Besides Orionite. A super-predator will not, I repeat not, push echinoderms out of the water. All the super-predator would do would be to push the echinoderms into producing a potent venom. Nothing more.




As for tripedal birds, marine birds and penniped birds are perfectly fine. But the tripeds could not gain dominance on land. The bipedal icthyornids would take over from them easily. Besides, with basic chordate anatomy, it would be both ridiculous and impossible for a tripodal structure to evolve.






That said, there is only one way ANY of this would be possible while still keeping it on Earth: diverge at an earlier point in Earth's history. All this stuff is impossible at a K-T divergence. But if you start in the Cambrian or Precambrian, the plausibility shoots up tremendously.

That still doesn't mean that they won't have the water vasculatory system! That's like saying that tetrapods aren't land fishes, but derived from fishes.

Hey Janlor, if you want a land starfish I recommend you to wait until Canis Lupus makes his echinoderm post in his blog. He's going to try to make a plausible land echinoderm, but I can't think of any way.

I wouldn't describe them as land-fishes. :O.o:

By water vacsulatory system, which one do you mean?
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.

It's their version of muscles. It needs a constant water flow through their skin or they can't move. In fact, their hearts wont beat and lungs won't work. If echinoderms leave the water they suffocate, can't move, no blood running... It's a horrible way to die.

How does it work? How did they evolve it? Those things need to be taken in consideration before saying it.

I found out that you're in Sagan4. I want to say that Earth life doesn't work like the life of Sagan4.

How? Please explain how they moved away from using water. I can't determine if it will work until more info is given.
