| 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!

Heyall - does anyone know how difficult the process for becoming endothermic/ectothermic is? iirc there's only been one species of mammal to re-evolve ectothermy and I wanted to know if that would have been a difficult/very slow process. |

sorry for my ignorance, but I looked at your project and found nothing about this "antmice", so I would like to understand more how this works. about the flight, I want to say the flight to the normal "rhinogrates", of normal size and not for the "insects"(But I've seen it now so maybe its possible https://en.wikipedia.org/wiki/Kitti%27s_hog-nosed_bat ) and adding, why do insects (and a lot of other animals) manage to be so small?

I understand that after the hypothetical second Pangaea that is thought to occur in the future, after that any details on future continents becomes somewhat hazy. However, can anybody point me in the right direction of how the continents may split up? Or do we have no clue whatsoever? |

We basically have no idea what's going to happen as far as I'm aware. That's where speculation on what continents after Pangea II is basically speculation. You can imagine what the continents would look like but their formation depends on how the supercontinent splits itself |

Similar to how the recent super continent split up.At least 4 or many continents can form. Pure speculation |

Here they are. Insects started out small, AFAIK, and sub-centimeter size are the default for most or all phyla. Hoeothermic metabolism just really penalizes small sizes. I also recall reading somewhere, maybe on Gert Van Dijk's blog, that external skeletons are more efficient than internal ones at a small scale. |

Hmm, been thinking about New Zealand and the Seychelles. Both are fragments of continents, and both are either largely submerged, or were in the past. Both have no land mammals, but both are home to fairly diverse reptilian and amphibian fauna. But both would have had mammals at one point. We do have a mammal fossil from New Zealand, and both islands were part of chunks of Gondwanaland at some point. There are two possibilities when it comes to this fauna. One, that these islands were totally submerged, and that all life there colonised it from nearby landmasses. Two, that their were small island refuges that remained above the sea. This seems to say one of two things. Either, frogs and caecilians are better at rafting across open ocean than mammals. Or mammals are not as well suited to surviving in tiny refugia. I'd suspect that it's the latter, but does anyone know better? The whole thing is made more confusing by the fact that mammals clearly can raft pretty large distances, primates and rodents colonised the South America and Madagascar from Africa after all. |

I suppose the fact that the St Bethans mammal made it to New Zealand and died off suggest one of the causes for it's extinction could be the latter but it could also be other things like a minor extinction event, climate change, disease etc. New Zealand, as much of a fragment as it is, is still an impressively large landmass compared to other islands so I don't think mammals would have a tough time surviving there for millions of years. Especially when New Zealand is a similar size/maybe larger than Madagascar and mammals have done very well there for tens of millions of years |

I'm fairly sure that at some point in the past New Zealand was mostly or even wholly submerged. The islands as they are are obviously large enough for mammals. |

Are there any major changes that a mushroom would have to go through to become aquatic? Obviously there would be a few necessary changes that would allow them to survive, but what would those necessary changes be? googling "aquatic mushroom" results in references to a Psathyrella aquatica, but i was unable to find any specific information on what allows it to have an aquatic lifestyle.

can bats occupy a niche like those of birds? (not the actual bats, but a flying mammal as a bat but not so specialized for echolocation) (yes I know that birds occupy many ninchs, but I think of something like colorful day bats like tropical birds) and just as a joke, it would have like a bird to develop echolocation ? like birds bats and bats birds.edit I just discovered that there are birds that do echolocation [https://en.wikipedia.org/wiki/Swiftlet] it's surprising how lately I've been interested in clades that I've always reneged on, like rodents and bats ... maybe one day I'll come to like birds Edited by Cool_Hippo43, Apr 16 2018, 07:00 PM.

hum, back the colored plants As would be the dynamics between these different species of autotrophic type, the earth is dominated by green plants, but in a planet with plants of other colors as they would be distriución them by the globe? They could exist together creating different types of biomes normally, or one would end up always leaving in front of the other ?? Edited by Cool_Hippo43, Apr 17 2018, 05:52 PM.
