| 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.

I was just thinking about the future evolution of domesticated dogs in a "humans disappear" scenario. I know that wolves are likely to rebound in a major way in their former range in North America and Eurasia. Even dogs that survive the loss of humans and are able to hunt and survive on their own are likely to be killed or absorbed into the burgeoning lupine population. However what would happen on islands that wolves would not be able to get to. How would dogs end up looking in places like England , Ireland and Japan. Would they end up looking like the wolves that used to live on these islands (as they would be filling a similar ecological niche) or would they look very different |

I... sort of disagree with this answer? But it depends on the environment the alien evolves in, and what you define as being similar to Earth life as well as how you define being anthropomorphic. There are some features of Earth life that will likely be present on other planets, provided the planet is able to support complex life. For one, based on what we can observe, aliens are likely to use water as a solvent and will probably be carbon based. Likewise, features that have evolved more than once in Earth's history are more likely to evolve again on other planets. Eyes are very likely to evolve again (they've popped up independently in at least mollusks, vertebrates, arthropods and cnidarians), as are limbs. Jaws and fuzzy integument have evolved more than once and are likely to evolve again as well. Bipedal motion has evolved again and again in vertebrates, so could probably pop up again in a terrestrial organism with paired limbs. So, a bipedal, terrestrial carbon based organism with eyes, jaws, fuzzy skin and paired limbs could probably evolve again pretty easily. Is this anthropomorphic? That's up to you. Both humans, kangaroos, and ostriches fit this description. I guess I'm trying to say that there are a lot of features present in Earth life that are very likely to appear again on other planets.
Yes, darkling beetle larvae can eat polystyrene! At least, that's what certain peer-reviewed studies suggest (Biodegredation and Mineralization of Polystyrene by Plastic-Eating Mealworms: Part 1. Chemical and Physical Characterization and Isotopic Tests). Supposedly they have microorganisms in their gut that can digest the styrofoam, and they can incorporate the carbon from the plastic into their lipids. And as for complex mite behavior, that could probably evolve? Spider mites seem to live gregariously and work together to protect their nests (Variation in social behavior within a spider mite genus, Stigmaeopsis (Acari: Tetranychidae)), while dust mites appear to prefer to migrate down paths that their kin have already chosen (Collective Migration in House Dust Mites). Since mites that already exist have evolved the ability to sense where their fellows go, they could probably evolve to sense where tardigrades are. And since some mites have already evolved an instinct to collectively protect their nests, they could probably extend that instinct to protect a food source. Tiny animals are constantly surprising us with their ability to perform complex behaviors, and based on what we are learning about their behavior I see no reason why mites would buck this trend.

When I read the original question, and what I presume Russwallac thought, I figured they meant proper furry anthros ala Fursonas. Imo there are many traits that would likely show up on other planets, but take on new forms. A carbon-based organism with eyes, jaws, fuzzy skin, and paired limbs would include both earth dogs and (depending on what you consider a jaw) Illion's wooly starusses. |

That makes sense too! I thought that Russwallac meant that multicellular aliens would be very unlikely to evolve any trait common to Earth life. I've seen lots of people out there in that camp that think all aliens have to look like surreal, eyeless Barlowe-esque things and I'm just not sure that's likely. Not that Expedition is bad! It has some of the most breathtakingly unique alien designs I've ever seen! But I think it's a better piece of art than it is a piece of hard science fiction. I'm also the kind of person that would say that dogs and starusses have a lot of similarities, so there's that ![]() |

Despite that dogs are domesticated animals, they have become so dependent, so reliable on humans that they will end up dying out with mankind (if they were in a "humans disappear" scenario). |

I'm going to have to disagree, while many breeds of dog are small, weak, and very sickly thanks to human breeding and would die out there are also hundreds of dogs that have either not been breed so much that they're useless in the wild, or have in fact been breed to be better at survival in certain ways. While pugs would likely not survive, Labradors, Bloodhounds, Greyhounds, etc could possibly survive and diverge into the future. A question of my own in regards to creatures with legs running straight along the underside of the body in a line (as an example, the Gyrosprinter from Darwin IV). Is it better for balance to have the body wide and flat, tall and thin, or just a general cylindrical sausage shape? I'm looking at the possibility of having a running creature with a similar leg-plan and would like to know which way I should lean the body shape. |

But they're less efficient at it than cats or mustelids. Dogs are really "in their element" as pursuit predators of big game; they aren't as good at hunting small prey on their own. New question. How did bone skeletons first evolve in vertebrates? Could the same set of features that led to bone skeletons have just as easily arisen in other animals besides chordates?

IIRC the origin of our skeleton was just a simple mineralization of an already-existing, cartilaginous skeleton. As for other clades developing bony skeletons, I'd probably say not, save for maybe mollusks and non-chordate deuterostomes. |

about pigmentation in plants ... I would like to know why plants are green (not necessarily how that works but why green color?) is the most energetic way or something or is it random? could plants with other pigments exist? such as yellow or blue plants? If so, what could exist could be that the ancestors of the plants "changed color" evolving into plants with different colors (but still being plants), or the only possibility would be another totally separate kingdom. would it be disadvantageous to have other colors without being green? (using as base a planet analogous to earth and a star similar to the sun) |

some harvestmen also seem to have some weird internal thing going on,read theuy even have calcium about plant pigments yes there can exist other fotosintesis pigments and is usually linked with type of star, on sun type stars is a bit of random we have green plants but there are photosynthetic purple bacteria,cyanobacteria that area litle more bluish, not to count all algaes that we have from brownish to red pigments |
