| 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!

I have a related question to the one I asked earlier. A lot of future evolution scenarios--the Neocene Project, for example--have the Hawaiian islands and other volcanic islands still existing as much as 25 million years from now. But I was under the impression that volcanic islands were usually short-lived, lasting for a few million years at most. |

You'll want to go to Preferences on the top right of the board, Update Profile in your profile options and then type in your member title. The Hawaiian hotspot has been going on since the Late Cretaceous at least, potentially older if there's more seamounts that have been subducted beneath the Aleutian trench, leaving a trail from the trench all the way to the modern Hawaiian islands. Some mantle plumes like that can last for quite some time. |

And back to my old question, are there any marine mantle plumes we know of now that are currently underwater but could potentially form islands in the future? |

Does anyone have any estimates for how long the Galapagos island chain will exist? How about New Caledonia? Socotra? |

What is the etymological difference between 'spiracle' and 'nostril'? I've done some research, but all I've come across for spiracle is 'a usually respiratory opening'. Any ideas? |

The way I'm familiar with it being used, a nostril is a specific kind of spiracle connected to a set of nasal passages. People are unlikely to use the term spiracle when the term nostril is available, though with some animal groups it happens now and then, like blowholes of cetaceans sometimes being called spiracles. |

Is there a thread where you can ask for suggestions for the naming of projects? If not, can I start one? |
|
Projects I'm probably going to do: Evolutionary continuum: Currently unnamed project- takes place 250 million years after the extinction of man Alternative Evolution: The Sanctuary- The best zoo in the world The Habitable Zone: Sapients of the universe- exactly what it sounds like Alternate universes: A bestiary of the land of Hyrule- again, exactly what it sounds like Ixuligaxa- A Sheatheria-esque project but the wildlife came from the orvadacian and earlier. Café Cosmique: Ultimate power- A gritty reboot of Power rangers, but not too gritty, some xenobiology and posthumans The menagerie- A world where a team is formed to combat the increase of crimes by Folklorish and Mythological creatures To Sum It Up- a bestseller in the sanctuary universe, It focuses on Rises and Falls, Trials of the century, and the worst of the worst | |

In lines of the Galapagos, there really isn't any estimates, but we do know a bit of it's history, that might help us figure it out. First, the volcanic province that made the islands is relatively young, having begun around 20 million years ago-maybe a bit more, but that still up in the air. This would seem to indicate that it might still be quite active in the future. However, we also know that the mantle plume's maximum potential intensity is similar to the Icelandic plume and only half as strong as the Hawaiian plume. Now I'm going to go on a bit of a speculative leap here, but this may indicate that the Galapagos plume won't last nearly as long as the Hawaiian plume, so the island chain may not last more than... 50 to 100 million years? I'm spit-balling with that estimate, btw. Although do note that even in that case, the islands 50 millions hence will most certainly not be the current islands, but entirely new ones. The Nazca plate will move those current islands off the mantle plume, and they'll erode to nothing over time. |

Removing helium and other impurities would also help, probably more than just adding more hydrogen. Also, you get colossal amounts of raw materials. |

To what extent does the motorized flight resemble the swimming, without prejudice to the locomotion on land? In comparison to Earth's gravity / atmosphere, what would be a good number of gravity / atmosphere? for example, we want to make it easier to get away, but we do not want everything to fly for nothing. And also about atmospheres, what is the relationship between dense atmospheres and turning the planet into a hot hell? Does it depend on the composition of the atmosphere or your mood? (In thesis we want dense atmosphere, but not a Venus) and Do most arthropods support large temperature changes? like Very hot and very cold places? Edited by Cool_Hippo43, Apr 4 2018, 05:03 PM.

Okay, after reading a little about corals, I discovered that some do symbiosis with dinoflagellates, so I thought of some kind of evolution of a totally autotrophic coral, like a new kingdom, one analogous to plants, but aquatic. is there any limitation in this development? another thing, the corals are several polyps together, an anemone is like a great polyps alone and totally "evolved" right? |

There are no name suggestion threads, but you can certainly start a project whenever you want to. |

Well, corals are already sort of analogous to plants. They are sessile, spread asexually, and use sexual reproduction to establish new colonies elsewhere. Some reef corals might be able to grow without zooplankton to eat, and their zooxanthellae definitely help coral to grow. I didn't read the whole thing, but here's a paper that explores the topic of whether we should consider corals autotrophs or heterotrophs: Reef Corals: Autotrophs or Heterotrophs? Corals are a bit more picky than plants, which can limit where they grow. They like water to be consistently pretty warm, and tend to like stable salinities (they don't like growing near estuaries). They tend to have a hard time in intertidal areas because they don't like being exposed to air, but also don't like growing too deep because this limits the light they get (low light makes it hard for them to photosynthesize and secrete calcium carbonate). They also need clear water with little sediment suspended in it, as sediment can cover the coral and hamper photosynthesis and feeding. So, even if they were entirely autotrophic, corals would have a hard time establishing a wider distribution. And yeah, anemones are solitary polyps! Corals can also grow as single polyps, but they are distinguished by (among other things) their ability to secrete a calcium carbonate skeleton. Both corals and anemones are polyp shaped cnidarians, which is essentially an upside down medusa (what jellyfish spend most of their life as). |
