| 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!

Seeing as bone is derived from cartilage and cartilage apparently exists in various types of animal besides just the chordates then I see no reason why one couldn't potentially have had bony skeletons evolve in non-chordate animals. Could perhaps make for some good alternative evolution spec. |

There are also a few plants that have leaves that are not green, and are colors such as pink, red, or purple. Now, these plants are mostly ornamental, cultivated varieties, but a few are like that in the wild as well. Can't remember which ones off the top of my head though. |

so plants of all colors can exist, that depends on the star. but based on something like the sun, there could easily be bluer or greener plants (such as cyanobacteria and purple arhaceae) |

non green pterrestrial plants are still something I don't understand also important to say about the bacteria, their are anaerobic but yeah plants could have totally have use other pigments Nano´s blueworld uses lichens with cyanobacterial pigments and teh fact that green pigments were dominant was a bit of "random chance" afaik |

On a somewhat related note, what of photosynthetic life forms that aren’t the same color as their photosynthetic pigment? For instance, as a hypothetical example, could a green plantimal become red or blue or brown if it offers a selective advantage (e.g. camouflage), or would its body being a different color from its photosynthetic pigments decrease light absorption too much? Must organisms give up their photosynthetic devices if they wish for their skin to assume different colors? |

An organism which is a different color than its photosynthetic pigment is just blocking more light from said pigment. |

Even if the plant is purple and their photosynthetic pigment is blue? I thought that might work because purple is a mixture of blue and red. |

Purple light isn't a mixture of blue and red light. |

Okay, I think of a planet with less gravity and an atmosphere denser than the earth. In this place are only relatives of gastropods, bivalves, plateomints, lobopods, echinoderms and other things that you consider "slow" and invertebrate (no arthropods). How could the flight evolve in this place? Maybe gastropods flapping "wings", but I do not know if that is a good one. Or descendants of lopodes (as in diyu) that glide and can flap wings. so how can flight evolve into soft stuff? does some kind of Ossification necessary for such an action? What else could you have on this planet that would not be a risk to the slow gastropods? |

Does anyone know how electricity might interact with different minerals, especially ones that are most commonly found in caves, such as quartz, fluorite, gypsm, calcite, etc.? |

assuming that a super advanced (very advanced) civilization, which has the knowledge of building planetary systems and creating planets, how could they save a star dying? Just always throwing more "fuel" in it? |

Well stars are powered by nuclear fusion and if I'm not mistaken this is due to all that gas being compressed so tightly (NOTE: technically stars are in a plasma state rather than a gaseous one, though all that plasma is derived from gases). I guess throwing some more gas onto the star could help though there are the issues of where to obtain all this extra gas and how to get it to be incorporated into the star. I have no idea how that would work or even if it could at all work.

It's important to remember that vertebrates and arthropods came from very "lowly", squishy stuff (lancelet like animals and lobopods respectively). They key to getting past this is the development of 2 key features. A hardened skeleton (internal or external) and a skin/covering that prevents significant water loss. These conditions are what allow for the rapid spread into inland environments and set the conditions for flight to evolve. |
