| 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!

Dinosaurs also once had ancestors with flexible backs (lizard like stem archosaurs). If they an change, so can mammals. |

@Setaceous Cetacean: That means about double the oxygen partial pressure on (SL) Earth which is safe without any need for acclimatisation. At that pressure, though, mild nitrogen narcosis will set in. Likely impaired performance, reasoning, and possibly mild euphoria. I don't think the effects of chronic nitrogen narcosis are well understood but they may be important. Best to bring your own breathing mix. Following good practice in moving between pressure levels would be important for avoiding nitrogen narcosis and air embolism. |

Interesting. Thanks! How could Archosaurs (IE, Saltwater crocodiles) get around whatever the reasons they can't become viviparous? |

Do all plant cells have chloroplasts, even the ones in the bark, interior, roots, etc? Is there any precedent of chloroplasts being lost? |

Someone can correct me if I'm wrong but I'm sure the bark of large plants (so trees) consist of dead cells that effectively become a necrotic shell for the plant and protect it from environmental wear-down and herbivores that can eat the inside of it. So I don't think they have chloroplasts, or if they do they aren't functional anymore |

Even in a leaf, epidermal cells usually lack chloroplasts. Inner stem and root cells usually miss them, as do many cells in plant reproductive organs. Ghost orchids have chloroplasts only in specialised roots. Pinesaps, among with several other parasitic plants with mycorrhizal associations (most famously the the ghost plant), contain none. |

Are elephant seals currently at their maximum size to be able to move on land or could they reach greater sizes before terrestrial movement becomes difficult or even dangerous for them? I'm thinking of a upper limit of 7,000 kilograms; is that alright, too much or could they get larger? I'm specifically referring to the males since... well it's sort of obvious |

Does anyone have any good resources on the quality / content of soil in alpine regions? I haven't been able to find anything on the subject that details things such as the amount/percentage of various nutrients and only a vague "rich / dry" thing. |

Would it be possible for carbon-based organisms to incorporate gold into their biochemistry, as with other types of minerals? |

depends on what you mean by "their biochemistry"...into their skin and hair or other tissues, sure - that's actually how morgue doctors can determine if a victim was exposed to arsenic or other toxins: just take a hair sample. if that's not what you mean, then I don't know. sorry. |

Other than increasing leaf size, what ways could a plant evolve to maximize captured sunlight in low light conditions? |

The most immediate thing which I could come up with is to darken its pigmentation. Darker tones absorb more light. |

So then would black leaves be the most efficient, as black absorbs all light? |

Technically, yes, due to that simple fact. However, iirc, the atmospheric composition plays into it too; certain wavelengths are scattered in the upper atmosphere which leaveshehe only certain wavelengths viable for collection. Hence why we still have green plants when black ones could dominate. |

Yeah, I was basically thinking of an animal (probably a reptile) with gold in its skin, scales, teeth and bones. Fossils of these animals are well-preserved like Borealopelta, with their skin and scales still there, and their bone agatized. Upon discovery, the gold is still there and combined with the gembone and well-preserved fossils their remains basically become treasure. |
