| 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!

Yes. (seriously, it depends upon gravity, atmosphere thickness, body support structures, limits to support/breathing/reproduction/something else, if it lives on land/sea/elsewhere, etc) |

IIRC, Mammalian Hair is more suited to keep them warm whereas Arthopodic hairs are more used as sensors to help track prey from large distances through vibrations. Could be wrong though. |

As said earlier, arthropod hairs (which are called setae) are primarily sensory organs. Though some do have unique uses for it... |

It's worth noting that there are actually a number of living eagles that approach or even exceed the Haast's eagle in terms of wingspan-- the Steller's sea eagle, the wedge-tailed eagle, and the golden eagle, to name only three. |

There is a short video on PBS' youtube channel that explains how dinosaurs got so large, and goes a little into how mammals haven't been able to reach such sizes. It's explained by the same guy that does the CrashCourse videos on another channel. EDIT: Got a question of my own; could an animal adopts its behaviour for one purpose to suit another purpose? I know that sounds vague and confusing but I'll explain. I just recently found out that some dubia roaches will raise their abdomen upwards as a form of mating display and realised these could be a new insect species/genus/family for Future Planet (name for now will be peacock roaches, or pearoaches). Now the fan-like rear would be used for mating purposes, but I'm wondering if roaches could adapt their behaviour to be used as a defensive mechanism against threats (basically realising their fan is useful against threats as well as for mating). I realise more intelligent animals could realise something they do could have multiple purposes but I'm not sure about insects EDIT. AGAIN: Ok just thought of something else. Ignoring what our skies would like, how would Earth be like if the moon was a ring like Saturn's rings, or when the moon was actually a ring some four billion years ago? And would the width of a ring make a difference? Like how significant would the effects of a 1,000 mile wide ring be compared to one that is 10,000 miles or more Edited by CaledonianWarrior96, Feb 10 2018, 09:35 AM.

It's probably best to think of it the other way around, why did sauropod get so large? Because no other dinosaur approached them in size. Were it not for sauropods we might assume the largest land animals can get is 20-30 tonnes. The biggest stegosaurs, ankylosaurus and ceratopsians were all comparable in weight to living elephants. Even the most massive theropods and ornithopods were not heavier than the largest extinct elephants and indricotheres. Sauropods probably had a perfect combination of characteristics mentioned in other posts that allowed them to break this barrier. |

can "cultural" behaviours affect evolution without reaching sophont stufflike stuff that is learned and teached could that affect an animal evolving into a different niche |

right after the Big Splat, our Moon was a ring around the Earth...from that, formed what we call our Moon. if we had rings now, I imagine tides would be determined by where the densest group of ring-rocks were (or the most rocks), rather than a regular monthly cycle. as for behavior - sure, its called preadaptation...and you gave a pretty textbook example of how it works. imagine if an early feathered beast flapped its arms to win over a mate - millions of years later, its descendants use that same behavior...to get slightly airborne. |

Interesting video. Incidentally, seeing as he says that one of the size constraints is that bigger mammals need to birth bigger young, then what would this say in the context of non-placental mammals where they will either birth tiny larvae-like young or have such young hatch from eggs? Could this mean non-placental terrestrial mammals could potentially reach greater sizes than terrestrial placentals given the opportunity? (though of course the lack of hollow bones and air sacs will still be placing constraints on their maximum sizes). |

Mammals are also kind of badly constructed as organisms anyways. Their ancestral forms were small borrowers that needed very flexible bodies, which are good if you're small, but when you get large, your back kinda fails to support it as well compared to dinosaur backs which are comparably stiff. |
