| 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!

OK. You might remember that I earlier posted a topic about the plausibility of the atmospheric animals in Kenneth Oppel's novels. Well, that inspired me to post an entirely new topic of the sort about how the Earth's atmosphere could have been colonized by vertebrates, starting about 30 million years ago. Step 1, 30 million years ago: The first colonist, an the keystone species of this aerial ecosystem, is a species of fly. This fly's larvae have evolved the ability to "balloon" great distances, like baby spiders, feeding on airborne pollen grains and algae. They only touch the ground to pupate and when they are eggs--the adults are also exclusively airborne. Step 2, 25 million years ago: One species of these flies evolves swarms, great masses of larvae that float thousands of feet in the air. They are, however, easy prey for predatory insects such as wasps, some of which evolve a similar life cycle to prey on them specifically. Step 3, 20 million years ago: The next breakthrough occurs when birds begin to evolve species specialized in these atmospheric insects. Most of these birds are related to swifts and swallows, and they spend the majority of their lives in flight, hunting the insect "plankton." Naturally, they are followed by birds of prey. Step 4, 15 million years ago: Here's the difficult part. Some of these birds become even more specialized. They overcome their inability to evolve vivipary by storing their eggs in a brood pouch of skin as they fly, and almost never land. They reach enormous sizes, with 12-foot wingspans and weighing over 35 lb. With arrays of bristles around their mouths to funnel in insects, they are the baleen whales of the sky. They, in turn, are preyed on by highly specialized raptors. By this point, the sky is a fully functioning ecosystem Any thoughts? Edited by Scrublord, Dec 23 2009, 05:39 PM.

Venatosaurus: These kite-like critters.... Will they be plant-like; with the 'kite-'tether' working like a root system? |

I actually just recently designed an air-dwelling species, although they seem highly impracticle and I'm pretty sure they couldn't fly on a planet unless it had decently lower gravity and a thicker atmosphere.![]() I just wonder how social patterns would work differently in the air... |

If it lives on the air wouldn't it be more pratical if it lacked legs? |

I'm probably wandering off-subject just a bit, but..... Yellowdrake; I was wondering, assuming such creatures came to be.... What would compell creatures to live in the air all time?(Evouloutionly, speaking, of course) |

That's the whole reason I created those flies: as a food source that would compel animals to take to the air. |

You don't need to use much energy on movement, predators find it hard to reach you, you can go faster, you can see further, etc. |

Time flows like a river. Which is to say, downhill. We can tell this because everything is going downhill rapidly. It would seem prudent to be somewhere else when we reach the sea. "It is the old wound my king. It has never healed." | |

This is really clever! Maybe bats would work better than birds, since they're viviparous and don't have to worry about eggs? |

Unless the birds could do a surinam toad and have the eggs inside its back. Learning to fly, however, could prove troublesome... |
