WHAT IS SPECULATIVE EVOLUTION?
Speculative evolution is the exploration and imagining of how life might evolve in the future or could have evolved in alternate pasts. It's a multimedia sci-fi genre that harnesses scientific principles to create detailed and plausible hypothetical creatures, ecosystems, and evolutionary histories.

I like seed worlds and speculative ecologies. Imagining how species interact and form novel ecosystems is fun.

what about a bird but with bat wings?

The problem is that bird wing fingers are locked tightly together, the opposite of a bat wing.

This, but apparently they weren't good fliers/gliders

Why would birds evolve in this direction when their wings are much more efficient than bat wings?
Anonymous No.5041616
>>5041464

They're not as efficient though. One feather too less and they're flightless, while bats can operate with 20% of their wing membranes gone.

Further, bird wings are mostly dead tissue, while bat wings are living tissue all the way and can flex and bend, adding more agility
Anonymous No.5042230

They didn't evolve in that direction. Scansoriopterygids are well outside of Avialae and represent a totally independent evolution of flight in dinosaurs. And they're a lineage that was probably outcompeted by birds given that there's no evidence of them outside of the Jurassic

no, bird wings are really inefficient, theyre only good at soaring, not so much with tight turns, also bird are kinda badly "designed" at flying, because you have legs, which do nothing to aid with flying, only landing.
and think about the amount things that a species to go through to achieve feathers, its like intelligence, theres a much easier path that have existed and worked, pterosaurs were extremely successful, lizards and squirrels have developed skin flaps, by all accounts feathers are a fluke that really shouldnt exist

I don't think anyone has scanned it. It's not on Zlibrary either and it seems to only be available in hardcopy. I haven't found any digital copies for sale.

Pterosaurs were even worse at tight turns and such than birds, there's a reason birds outcompeted pterosaurs at every small niche
Anonymous No.5043588 >>5043628

Not true, there were small pterosaurs in the Late Cretaceous like Piksi. There simply are not enough sites with high degree of preservation.

Pterosaur wings were pretty efficient, more so than bird wings but perhaps not as much as bat wings

yes, but pterosaurs got fucking hueg, 10 meters across and as heavy as 500 lbs, the heaviest bird was 7 meters across at 270lbs, and wasnt some bitchass scavenger, it was a predator through and through because it didnt waste its time on legs, it put all its effort into wings
the only reason why birds are successful is because pterosaurs arent around, and even then, the moment they suffer a setback, bats are waiting to take over the diurnal timeslot

there were some small ones remaining but given that pterosaurs went extinct while multiple separate bird lineages made it through, that's a fairly good indicator that the smaller niches were dominated by birds

birds absolutely had several advantages in several niches over pterosaurs, as evidenced by them managing to establish themselves while pterosaurs were already widespread, same thing with bats having advantages in several niches over birds

>>5043591
Bats can't soar, so any aerial niche that requires it is pretty safe for birds, now that does leave them possibly vulnerable to getting pterosaur'd but bats have been around for a while and haven't really managed to intrude on the passerines in any way

not multiple, only three and barely

bruh, soaring is literally just holding your arms out, its not rocket science
and again, moving into a niche while its occupants are still there is extremely difficult, and bats have only existed for 50 million years and have taken over the entire nocturnal timeslot, birds have been around for 140 million and all they got is owls
Anonymous No.5043725 >>5043904

three is multiple, the fact three made it through and 0 pterosaurs is not just purely through luck, birds were represented significantly better in niches that would let them survive the K-Pg event

>>5043690
And bats can't do it, their specific form of flight and their wing structure simply can't give them controlled soaring unless it is completely restructured, and none of the niches bats occupy really give them evolutionary pressure to evolving it, since it would likely come at a cost of their maneuverability which leads to momentary fitness decrease

And I already mentioned that bats are better at several niches, just a couple in particular that they're unsuited to taking from birds

there's also nightingales, nightjars both of which have large distribution

>that's a fairly good indicator that the smaller niches were dominated by birds
no it isn't
the three lineages of birds that survived were all ground nesting semi-terrestrial animals, the more arboreal enantiornithes which were the dominant clade of birds at the time that you'd be arguing out competed pterosaurs all died out as well.
