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.

Also bear in mind the ecological pressures that dictated the form and size of the eagle. Haast's eagle hunted in a similar manner to how other eagles hunt, and so required very strong and powerful wing and leg muscles to give it enough power to fly fast, manoeuvre rapidly, and bring down very large prey items with its talons. This musculature would weigh it down more, and while perhaps the bird could have weighed as much as other giant birds, the eagle could not afford to reach the same linear dimensions, especially considering it had pretty short wings relative to its body size for an eagle.

Haast's eagle was a compromise of both size and power, and other giant birds like the teratorns and pelagornithids had to sacrifice their overall body strength, particularly so in the legs, for them to reach the sizes they did. Neither teratorns or pelagornithids had particularly powerful legs, teratorns could at least walk quite comfortably on theirs but they had none of the same strength and power built into them as the eagle's legs. It's speculated that the largest teratorns in South America could only get so big due to the winds being blown in from the sea before the Andes got in the way to lift them off the ground, compared to the eagle which would be capable of launching itself into the air from a standing start with a good jump. I can't imagine a bog-standard eagle could reach the same wingspans as giant teratorns and pelagornithids without changing the way they're built, and how they behave, and they wouldn't just be a scaled up eagle in the manner of Haast's eagle.

Could chitons evolve camera eyes with an aragonite crystal lens??

Also I still don't get shipworms, how does it eat the wood shavings if there is a shell (the rasping thing) in the way? Sorry I haven't slept for 24 hours and this might be a really stupid question

Did all of the small long tailed pterosaurs (forgot their name) die out before the end of the cretaceous?

The only non-pterodactyloid pterosaurs ("rhamphorhynchoids") with a record extending into the Cretaceous at all are the anurognathids, and they stil have short tails, whether that be a shared trait with pterodactyloids or evolved convergently. In any case, none of traditional long-tailed pterosaurs are known from the Cretaceous, let alone the very end of it.

Yeah, non pterodactyloid would be a better term. Thanks.

I don't want to get picked on as usual ,like today,but that question have been answered a quadrilion times.About indian plate,it's still ramming into Asia.African plate,by popular belief,is believed that this plate is going lately to combine with europe,which we can't be sure.

Doesn't matter if the question has been answered before, a two word answer like that isn't helpful.

Anyone know where I can read more about the fauna/climate of the Eemian interglacial? It's such a fascinating period

I don't see how that question has been answered many times, it's not really that a lot of people ask the same, and in any case, it does not cost much to share the most common or most accurate answer, or if you feel it's annoying to answer, just do not answer it in the first place.

The plates are not combining, the African plate is diving under the Eurasian plate by subduction.

Err... no. Subduction doesn't work both ways.

So this was made in 2011 but I found an article discussing the subduction zone between the African and Eurasian plates. It seems the former was going under the latter but apparently due to differences in tectonic mass and thickness there is a switch going on. So I guess it looks like Eurasia is going under Africa now

Actually, that's an interesting idea: What if you had two c-shaped plates that hit each other at the points of the c, so that each was both subducting and being subducted under the other? (And yes, this isn't all that relevant to the specific Africa-Eurasia collision.)
