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.

@Scrublord: It depends-how would they become dominant in the first place? Fish struck on a very effective, yet simple layout; hard but small scales on the outside allow for protection while permissing side-to-side movement used in nektonic swimming, while an internal structure for muscles to pull against allows potential for strong swimming. Hallucigenia is a benthic feeder with protection in the form of external spines and is otherwise very squishy. I can see it if benthic fauna suddenly becomes diverse, though you would need to explain why.

Side note: Pikaia is actually closer to the lancelet side of Chordata, considering fish had almost already evolved in a recognizable form.

@gestaltist: I've altered it a bit since I made that original post. The planet is in an eccentric orbit, only coming fatal-twilight close at periapsis. It has a significantly larger magnetosphere than Earth, which helps with stellar wind and UV radiation being much higher than Earth conditions. But the real kicker is that the star is much older than the planet- by about several billion years. The reason for this is that Fonix is actually a recaptured rogue planet, its orbit reasonably stabilized by the revolution of a brown dwarf sibling at about 5 AU.

Little is set in stone, so please comment.
This was getting fairly big.

Only partly so, if the planet is still tidally locked. @Inceptis - hard to comment with so little data. If the planet is now on an excentric orbit, and not tidally locked, then you're good as long as the planet has the right atmosphere. Research suggests that a stable atmosphere can outweigh the temperature differential between the apsides. I would have to look for the papers I read about that.

Not that I remember. I did an entry for a COM where annelids were dominant, though.

Oh, sorry. I was thinking of Flish's entry for Old Life, New Beginnings.

So I was recently thinking of opening up Galapagaia again, but perhaps changing the setting sand scenario. For example, I think the initial list of species I introduced was too broad for true exploration, and I thought of whittling it down to essential cornerstone species and some key, most memorable members of the Galapagos isle. My thoughts are to include the key Tortoise, Iguana and Finches, but then I dont want to just create a bird dominated world that would most likely take place. So I may change it up entirely and rather than doing a Serina style epoch by epoch description, have it set in the far future of the world when all the life has settled into some extraordinary place, describing the evolutionary history as more of the planet is learnt about. Oh and rather than have it be a simulation, place it more in line with tampering aliens on a foreign world vein.
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:

Maybe have the finches perish early on (or end up restricted to Cocos Island or somewhere equally remote), and-or just focus on some of the other fauna and flora of the Galapagos...the snakes, maybe, or the bees, or...

Here's a project I've been ironing out for a long time now, and it's now in my signature as an upcoming work, so I figure I might as will put it here (though it IS something I plan to do eventually, so no stealing. . .)

I call it "The Big One". I got the idea from reading Stephen Jay Gould's book Wonderful Life, where he briefly wonders what life might look like today if a different group of organisms (say, Hallucigenia instead of Pikaia) had evolved into the dominant phylum of large animals on Earth after the Cambrian explosion. So I've decided to do exactly that--create a timeline where Hallucigenia gives rise to the dominant phylum on Earth. This is basically the Mt. Everest of alternative evolution. The Big One, in other words.
Needless to say, this project's going to take a lot of thinking. What direction are other phyla (arthropods, mollusks, etc?) going to take? What effect will mass extinctions have, assuming they're still the same as our world? But it's something I want to do nonetheless.
I like this. But there's something I must make clear, Hallucigenia is NOT an arthropod. Not anymore than a clonial salp is a vertebrate. I said this because I don't want neo-arthropods coming from this. Anyway.

As for true arthropods, they'll probably still colonize land several times. But maybe you could to a different set? Instead of hexapods, myriapods, and arachnids, you could do trilobites, nektaspids and phyllocarids. And maybe some more minor lineages become terrestrialized over time, such as fuxianhuiids, nektaspids, pycnogonids and eurypterids (just as isopods, amphipods, true crabs and hermit crabs in real life).

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.

Marellids would be interesting if they lived past the Devonian. Antler crabs for the win!

Fonix is still tidally locked, it's just that it experiences extreme libration of its sun, distributing the sunlight more evenly across the surface. It would also create some interesting spots in the shadows of mountains where the sun rises fatally and sets friendly, working vice versa.

Yeah. But imagine terrestrial pycnogonids.

Hmm. Tidally locked on a very eccentric orbit? Alright. Then we are back to my original question. You only have one side of the planet recieve heat. Air on that side will be constantly rising due to warming, whereas it will ge falling on the dark side. Such a one-sided movement will probably tear the atmosphere apart - it will simply evaporate into space on the day side. What is your solution? An eccentric orbit does little to change that.

Libration is an interesting concept but first you need an atmosphere. :)

unless it gets around to the other side of the planet (or even to any nonsunward side) before it evaporates into space.

yes, every planet loses some gas to space. even Earth (arid zones are particularly bad for this, my science lessons always said, because gas and humidity escaped the atmosphere during the day)...and yet Earth manages to survive 4 billion years with arid zones.

True, but Earth has various counterbalances. E.g., the most arid areas are in the subtropics where the air actually falls due to the Hadley cell terminating there. This prevents too much air from escaping at those latitudes. On a tidally locked planet, creating a stable circulation pattern is much harder - I'm not saying impossible, mind you, but unless you want to handwave it, it is the primary concern on such a planet.

Interactions between the planetary rotation (and Coriolis force) and the constance of the subsolar point are not trivial to calculate. It's a completely different situation than on Earth, where it's not a point but a band that gets the most insolation. Having a hot band allows for Hadley cells forming, and - subsequently - the whole atmospheric circulation with jet streams, etc.

With a tidally locked planet, it's different. The air movement wouldn't start North and South from the Equator, like on Earth. It would start North, South, East and West from a single subsolar point at the equator. It would be deflected by the Coriolis force to one side, but it would be more local.

Look here for some more information.
