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.

Well lots of plants make protein. I know this because I know a lot about potatoes. A potato contains 4.3 grams of protein (I like mine with raisins). Potatoes help keep me healthy and strong! So maybe the fruit could move.

Does anyone know how long it would take potatoes to turn into animals? What if there were no other animals on their planet?
I feel like such an adaptation would take quite a while, maybe like half a billion years
Projects and concepts that I have stewing around
Extended Pleistocene- An alternate future where man died out, and the megafauna would continue to thrive (may or may not include a bit about certain future sapients)
Inverted World- An alternate timeline where an asteroid hit during the Barremian, causing an extinction event before the Maastrichtian. Dinosaurs, pterosaurs, and notosuchians make it to the present, along with a host of other animals.
Badania- Alien planet that has life at a devonian stage of development, except it exists in the present day.
Ido- Alien world where hoppers (derived flightless ballonts) and mouthpart-legged beasts are prevalent.
Leto- Life on a moon orbiting a gas giant with an erratic orbit; experiences extremes of hot and cold.
The Park- ???
Deeper Impact- a world where the K-Pg extinction wipes out crocodilians, mammals, and birds; squamates, choristoderes, and turtles inherit the earth.
World of Equal Opportunity- alternate history where denisovans come across Beringia and interact with native fauna. Much of the Pleistocene fauna survives, and the modern humans that end up crossing into North America do not overhunt the existing animals. 10,000 years later, civilizations exist that are on par with European and Asian societies.
The Ditch- Nothing is what if seems..

Do moons have to be terrestrial? Could they be gaseous? I know they would probably be all terrestrial but I wonder if that's a rule.

I don't know a great deal about astronomy but I don't know if a gas giant (or a gas planet in general) can be a moon. From what I know most gaseous planets tend to be massive and I think even if a gaseous planetoid ended up becoming a moon the gravitational pull of the planet it's orbiting would disrupt the structure of the planet and tear it apart, similar to what might have happened to Saturn's rings (even though that's a solid object).

I don't know if that can actually happen but that makes sense to me

Gas giants occur because a planetary nucleus develops sufficient mass to prevent hydrogen and helium from escaping its atmosphere. Several things change the threshold for this to happen, like how rapidly the nucleus builds up and how far from the star the core is. Gas giants can form with lower masses further from the star. this paper gives a figure of 8.5 Earth masses required to form a gas giant at 5 AU and 3.5 Earth masses at 100 AU.

Moons which co-form with their primary have an issue which makes larger moons spiral rapidly inward and collide with the planet, so there seems to be a ceiling for maximum co-formed moon mass. In our solar system, the co-formed moon with the largest mass compared to its planet is Titan, at 4,000 to 1 (Ganymede sits at a paltry 12,000th of Jupiter's mass). Giant impacts seem to be able to produce moons at around a 100 to 1 ratio as seen with the Earth and the Moon but I have no idea how that would work with a gas giants. Captured moons might be the best option.

At 13 Jupiter masses, you start getting brown dwarves, and for a body just below this point a co-formed moon with the same ratio as Titan would be a little bit more massive than the Earth, not in gas giant territory. A moon with the same ratio of mass between the Earth and the moon would be 51 Earth masses, a bit less than a 5th of Jupiter's mass, certainly large enough to hold on to a gaseous envelope... though the scenario that resulted in our large moon might not be possible for gas giants.

But, being near a forming gas giant and particularly a huge one might have all sorts of effects that make it harder to grow a gaseous envelope, and increasing primary mass might make the necessary ratio to avoid falling in higher and higher (Jupiter's size ratios indicate this).

I think the most plausible scenario is a capture. A smaller gas giant is perturbed into a distant orbit with a large Jovian.
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.

Probably never mostly because If i remember correctly, animals didn't evolve from plants at all.

Both evolved independently from single-celled eukaryotes.

In fact, animals are more closely related to fungi than to plants.

Pretty sure he simply meant "animal-like organisms" rather than "exact copy of animals". And, although almost certainly that could never happen on Earth (animals are simply so difficult to exterminate), he did mention that this would be occurring somewhere where animal competition is out of the question.

You remember correctly. Animals are indeed closer to fungi than to plants and are not descended from either. I think, however, that what hotpotato! may have meant about potatoes turning into "animals" was not so much about turning into true animals but rather about becoming mobile heterotrophic organisms. We might call such organism "animals" out of convenience rather than as any accurate classification.

Oh, sorry for my mistake there. I'm still a huge noob at this lol. Well to answer hotpotato question, plants have shown the ability to be mobile (Though not as much as animals) , so take a billion years or less, and maybe they could learn how to specialize the movement ability. Also, I'm really surprised on how fast and active this community is as the last forum I visited pretty much abandoned the forum itself for the discord.

Good morning/afternoon (depending on the time zone)!

Could prokaryotes or extratterestrial prokaryote analogs evolve multicellularity comparable to basal animal phyla, such as Placozoa?
After all, multicellularity has already evolved in Bacteria - just look at biofilm.

Is it possible that this level of structural organisation and extracellular communication could progress to more advanced forms?

Of course, prokaryotes have many limitations compared to Eukarya (lack of nucleus, organelles etc.).

A future Earth when eukaryotes will have become extinct due to CO2 starvation, an alternate timeline in which eukaryotes never evolved or an exoplanet with highly developed prokaryote analogs are all possible settings for such a proccess to unravel.

Imagine multicellular pseudometazoans in the Earth's far future!

Yes, but they may not qualify as "prokaryotes" in the traditional sense by the end of it.

Size of image = magnification*actual size.

So say if I am looking at a sphere 0.1 mm in diameter with a microscope set up for 100x, it will appear to be 10 mm in diameter at the eyepiece.

Therefore obviously magnification = Size of image/actual size.
