| 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!

Lets say dinosaurs some how became dominant creatures AGAIN after they lived a long time ago what would happen? |

We call that the age of birds. Mammals stayed tiny for awhile after most of the dinos went extinct. The giant birds kept us tiny for a long time. |

No no no, try a bird dominated world. Which shouldn't be hard. A recipe for mammal extinction is first make the world really hot and moist, then really dry while still hot, then mammals shouldn't be dominant since it's hard to survive really high moisture in hot temperatures, then hot and dry so that our lousy water conservation drives even more to extinction. |

A really hot and dry world sounds more like reptiles would take over, not birds (I think lizards are even more successful desert dwellers than birds, aren´t they?). |

Birds already have excellent water-conserving capabilities like their dinosaur ancestors and other reptiles. They could easily survive in a desert because it wouldn't take much tweaking for them to adapt to such environments. As for birds reaching sizes compared to large dinosaurs, its possible. They already have light bones and airsacs, so they could lengthen their short tail for balance when they reach large sizes. They could reach sauropod sizes if they evolve to walk on their wrists and adapt their forelimbs for bearing weight. Edited by Toad of Spades, Oct 14 2010, 09:37 PM.

Yes, because it's simply wrong. Birds were never dominant. Oh right, there were some big predator birds, but honestly, mammals became the dominant vertebrate group pretty soon after the cretaceous. It's like saying today's world is dominated by snakes and crocodiles. |

While birds always had and will always have a much higher biodiversity than mammals, they simply can't be dominant. Granted, birds have adaptations like a much superior pulmonary system, several adaptations to preserve water, and feathers, but they also have many disadvantages, like obligatory bipedal stance and ovipary, which simply make them inferior to mammals. Birds can evolve large, flightless forms in a world dominated by mammals, but thats about it; the only mammal group they can triumph over are bats. Pterosaurs, on the other hand, have less of the problems birds have, being quadrupedal and capable of ovovivipary. Combining that with the advantages birds have, they make more serious competition. |

ovivivapory? I thought all archosaurs couldn't develop ovivivapory. Yeah, if someone engineered a flying animal with all the advantages of birds and pterosaurs and wiped out mammals and birds, than they would have great potential for dominance. |

I think he meant oviparity, not ovoviviparity. And this is about dinosaurs again rising to dominance JohnFaa, not how awesome pterosaurs were. Because pterosaurss are not actually dinosaurs. I would have thought you would know that؟ Reptiles do very well in deserts, but birds do well too and unlike reptiles, birds can live pretty much everywhere else too. Aside from permanently at sea. Birds becoming the dominate form of life is going to take some doing, as pointed out mammals are just better at most things. It can happen, aside from pinnipeds and a few bats New Zealand's fauna was entirely dominated by birds, and still is for the most part. I can't think of anything that won't leave a rodent alive, but will keep birds around. A virus that infects and kill all mammals is ridiculous right? Edited by lamna, Oct 16 2010, 06:11 AM.

I doubt anything short of aliens setting up a unique resturant chain could plausibly lead to the extinction of mammals. They are highly adaptable organisms, and they don't go easily. |

What I said was that birds managed to keep the mammals small for a llittle while. The mammals won eventually. |
