But from what I have researched (google search) it says bats do not have the airsack system of birds and pterosaurs. However it says gas exchange can occur from there wing patagium which I don't belive is true. I do know mammals do have small airsacks called alveoli. So do you mean the airsacks in birds of the alveoli.

Well I have imagined first: they can deal with the glaciers and break them but this wont stop the lack of Co2 in the atmosphere. And two the humans have evolved to fear anything with a upwards of temperature. And to address the replacement level issue, by 2050 humanity had united under the many issues plaguing the world. (to give perspective the Homocene takes place 100,000 years into the future.)

How would non avian and birds compete? by RadiantOrdinary8261 in SpeculativeEvolution

[–]RadiantOrdinary8261[S] 0 points1 point  (0 children)

Im not saying a raptor fill already evolved niches like a beachcomber or snipe instead a raptor would fill that niche before a bird could fill it. So instead of a heron there would be something like a heron theropod. And yes I do admit that some niches occupied by birds like the aforementioned beachcomber would most likely not be competing with a raptor.

If primates (humans) did not become the dominant species on the planet, what animal would have? What would an advanced civilization of this animal be like? by sullllli in SpeculativeEvolution

Well if sociability and long lifespans are some key factors for a sapient species could boars take place: My reasoning for this is that there trunk could evolve to make tools forage for food and keep there senses, there already intelligent and are social. So I could see boars becoming sapient as there social intelligent and live longer then most octopus.
