Right, I have thought of a Sapient Humanoid distantly descended from primitive hybrids between ancestral Litopterns and Notoungulates. They have long necks, floppy prorhiscises, large incisors and forward-facing eyes with a keratinous horn on top of the heads in males. They have two opposable digits between their middle hoof-fingers on each hand and three hooves on each foot and stripey limbs.

>>3424529
If you mean dinosaurs, their size had nothing to do with oxygen levels, their bodies were simply better pre-adapted for large sizes in terrestrial environments than mammals are, such as having pneumatized bones that helped cut down on weight.

>>3424573
Arthropods becoming large was related to oxygen levels, however. Their breathing system is less efficent than vertebrate's so they need high oxygen levels in order to be able to survive at large sizes.

That said the size of Carboniferus arthropods is severely overstated by pop culture. Yes, Meganeura was massive for a dragonfly, but it was still only about as big as a hawk. Those "giant bugs" would still be dwarfed by even modestly-sized modern animals. The arthropod bodyplan is just not well suited to large sizes at all, and those issues extend far beyond breathing difficulties.

How do I make up fictional creatures that arent just obvious chimeras of real animals with exotic colors schemes but still keeping them somewhat relatable(having eyes, mouth, limbs, tail, etc)

Pic related is a good example, sure you could say it's some kind of rabbit/dinosaur/rhino mix but it's ambiguous enough to the point it feels like its own unique thing.

This is a superb series, so well researched and skillfully produced. However, the creature designs are kind of mundane. Every organism parallels some existing creature on earth, and there are very few unique niches or novel adaptations. I understand the limations of simple 3D models, but everything on this planet is a copy-paste of stuff on earth except with blobby spider monsters.

As a primer for explaining the mechisims driving convergent evolution and the universal laws constraining evolutionary adaptation, the series is excellent. But as a creative project it's a little lacking. I'm not sure whether the author's intent was the former or the latter. It feels more like a tutorial for speculative evolution rather than an actual world building endeavor.

That being said, it is certainly one of the most rigourous spec bio projects out there, and I can't wait for the next video.

Has their been any serious attempt to model a hypothetical ecosystem on a gas giant planet? Not just Sagan's floaters and sinkers but an actual interconnected ecosystem with a food chain and everything.

I've been brainstorming ideas about a Neptune sized planet in an F-class star's habitable zone (approximately the distance of mars). The low mass is crucial because the weather would be less violent in the temperate layer of the atmosphere. The key factor of the ecosystem is the layer of thermophile decompose organisms that inhabit the lowest, hottest layer of the "life zone" that consume any organism that dies and falls down through the atmosphere, with the Terran analogy being worms in the soil eating dead and decaying matter.

The atmosphere would contain an "aerial ocean" of water vapor with the volume of approximately 100x Earth's oceans, flying organisms ingest water through their lungs instead of drinking it. In addition to eye-like organs for sight, they have extremely sophisticated echolocation organs so that they can fly and navigate at night and avoid storms. More than just simple sound emitting devices, the organs would be true biological radars that emit actual radio waves, and predatory fliers would have their radar tuned to track prey .

F class stars don't live very long. Their main sequence phase is only 3 billion years as opposed to 10 billion years in G class stars like our sun.

It took 2.5 billion years just for multicellular life to take off on Earth.
>>
>>3434918
the existence of the francevillian biota shows that multicellular life could conceivably evolve within such timescales, a planet could conceivably also gain a longer lifespan than its star through being dislodged and absorbed into another star system which came to close, although using odds like that you end up getting a scenario where you might as well say that aliens or the divine did it because that would probably be more believable
>>
>>3434918
Huh?
>>
>>3434918

Star's lifespans shrink as mass increases. Red dwarves are calculated to live for hundreds of trillions of years because they can have 1/10 our sun's mass.

Unfortunately, red dwarves stars tend to be more irritable with their flare activity and can fry any planet in the habitable zone.

I like that sharks are apparently so perfect for what they do that the basic shark design hasn't changed at all for millions of years.
They've changed in size, but everything else has more or less went untouched.
It wouldn't surpize me if we found shark-like things elsewhere in the future, where evolution has more or less reached the same conclusion as earth.

Kinda like dingos. They were seperated from every other canid species on the planet as they evolved, but nature more or less said that certain designs just make sense, so they ended up looking more or less like every other dog

Here you go. The dolphin snake is an ambush predator inhabiting a chain of marshy low-lying islands. The tail and fins have become knobbier, and are used to shuffle along the ground, inchworm style.

The islands are full of large slow moving herbivores descended from rodents. The dolphin snake hides itself in reed thickets or shallow water. When a prey animal wanders too close it lunges forward, vicegrips the neck with powerful jaws, and pulverizes the unlucky critter with a vicious death roll.

A few decades into the future, a war between Israel and several surrounding countries eventually leads to the nuclear annihilation of northeastern Africa. A large majority of species were banished to extinction as a result of this, but a few clung onto their lives. The naked mole rat was one of the only vertebrates that was able to survive, with a few populations caught just out of the blast range. They were able to repopulate the wastelands pretty quickly due to their high resistance to cancer and soon created a new population much larger than before.

Several million years later, naked mole rats and their descendants have become the dominant mammal of the wastelands. Without any competition from other vertebrates, some mole rats have abandoned their ability of being warm blooded, instead opting to be heated by the sun. This type of mole rat has also stopped being fossorial and eusocial, instead living their lives similar to lizards. Males will climb up on rocks to watch over his territory. If he sees a bug, he will run to it and eat it. If a female enters his territory, he will try to make her stay; and if another male enters he will try to fight him off. They are most active in the mornings and evenings, when it is still hot but not enough to cause the rats to overheat, otherwise they will hide in burrows under rocks.

When a male successfully courts a female, she will stay in his burrow and later give birth to around half a dozen small little pups. She will feed them with milk while the male collects insects outside which he will chew up and feed to both his mate and their children. When they are able to feed themselves, the rat pups will leave disperse to new areas away from their birthplace. For now they lead a simple life, but as their habitat becomes less of a wasteland and new species start moving in, they will need to adapt to change.

A turtle from an island that reaches temperatures of about 30F very often, so they've adapted the means to heat up in the sun.
Curled rock climbing claws that can lift up while on the ground. A very wide shell (slightly wider than they are long) that's a greenish black with ribbons of red in between the chutes. Said chutes are spikes that aren't too tall, and lay flatter the farther out from the center they are, and the belly plates are raised so that they don't have to fully rely on their claws.Their necks stretch out about half their body's length, and the skin stretches wide to get more sun while they hang from the rocks, and is also a greenish black with a red line going from its eyes to the edge of the frilly skin (for mating season). Their beaks are stubby and strong, so they can eat nuts and sometimes small bones. The tail is very strong, stubby, prehensile, and acts like a hook.

They are omnivorous, but only predatory if the prey can be cornered, is too slow, or dead. They love fruit, but it's rare on their island, so they mostly eat vegetation and nuts.

could mammals ever develop the bright colors you find in insects, birds and lizards?
>>
>>3443683
sure! there's a good deal of mammals (particularly primates, since we have the excellent eyesight and colour vision needed to appreciate a colourful mate) that have developed very colourful patches (mostly on the face and ass/testicles)
>>
>>3443688
ah yeah mandrills, is green possible though? i was looking at some of those jungle lizards and snakes and wondered if a green monkey or ape would ever be possible.

>>3443688
Kinda funny that the most colorful mammals basically have a red ass or blue balls.
>>3443683
There's a bright green sloth because of algae.
>>
>>3443690
in theory sure! most mammals have super shitty eyesight compared to lizards, fish, and birds, so we've only just started getting this stuff with primates. and in jungles just having shadowy browns is as good camouflage as being green would be, so there's no real incentive for a mammal to evolve to be green even if we couldn't see it (especially when, to mammal predators like big cats, green and brown might as well be equivalent). but there's no actual barrier to a monkey evolving to be green. vervet monkey scotums are already edging towards the turquoise side of blue.

>Has their been any serious attempt to model a hypothetical ecosystem on a gas giant planet? Not just Sagan's floaters and sinkers but an actual interconnected ecosystem with a food chain and everything.
I don't think so. Just to get it to work you'll need to reinvent biochemistry. Carbon-water organisms would be too heavy and get destroyed by the violent forces of a gas giant. Ice giants on the other hand tend to be calmer, and you mention Neptune, or a Neptune sized sized planet. Neptune is an ice giant, but Neptune sized gas giants and even rocky planets with T H I C C atmospheres can exist. A warmer Neptune could even have liquid water.
>F-class star
I'd think an F-class star would put too much energy into a giant. F-class's have most of the benefits a G-class star (like our sun) and some of the detriments of a red dwarf combined with some of the problems of a blue star. Too bright, too radioactive, too much solar wind. All of this will be making your gas giant have some truly amazing but Hellacious storms constantly going. I'd recommend pushing it to the outer edge of the habitable sone, or outside of it altogether, as planets that large can generate some of their own heat, and the bulky atmosphere (depending on composition) will hold in more heat from the host star.
>at night
The entire planet would probably be in permanent twilight, as light is bent and spread through the atmosphere.

I'm working a bit on one. Probably won't amount to much though.
On that note, anyone have advice for developing the lineages through time? I've come up with a few phyla with unique general body plans for each, but coming up with specfic species and ecosystems at different time periods is tough. I'm planning to start it a bit by phylogenetic bracketing of the groups that have evolved a common ancestral trait.
Would appreciate help with learning about biomaterials like bone and cellulose and chitin. What other possibilites are there?

>Would appreciate help with learning about biomaterials like bone and cellulose and chitin. What other possibilites are there?
I forgot the name, but the fibrous parts from plants (like wood, the thing that gives earth plants rigidity). Also don't be afraid to get weird. An animal gaining photosynthesis from mutualism might eventually become spined trees. And organisms have to get the material for their bodies. A moon like Europa doesn't have the iron or calcium for Earthlike bones and blood, that's not to say those mechanisms can't exist, they'll just exist in a different way.
>>
>>3446825
I think the question you should be answering is why, not can. In biology the answer to can is usually yes. So in SpecBio the question you need to answer are how and why.
>>
>>3446833
I think lignin is what you're thinking of. What about it? I am planning to involve mutualism and endosymbiosis. I know I mostly only have CHONSP for Biomaterials, so that restricts it a bit. Is there some sort of general rule or theory for them? I know polymers are what I should search for, but there are so many...
>>3446825
I don't know about numbers for that, you can probably find that online somewhere. I would guess that for bugs to develop lungs, they would have to do it from some novel structure, considering how long they have been around breathing like that. Maybe from very derived setae or plastrons?
>>
>>3446825
Sure, why not. There's already bugs with inflatable body parts so that's part of the way there, right? What if moths evolved gas exchange in their weird inflatable pheromone organs?

There's a cypress and a few molluscs that do this. Sperm deletes the egg DNA, takes over the embryo. Species/population is all male, needs related females to reproduce.

The flip side of this, gynogenesis, is more common. It's just partheno with extra steps, you need sperm to trigger the egg and get it to divide.

I love speculative biology, but the online community can be such cancer. Why are so many autistic 13 year olds drawn to this subject? Why are so many creators pretentious and petty? Why is gate keeping and gish gallop so prevalent?

Every discussion inevitably breaks down into nitpicking, semantics, and pissing contests over who can spout the most psuedoscientific terminology. As someone with an actual degree in biology, the arguments over whether natural selection could do this or that are often totally spurious and based on fundamental misunderstandings of evolutionary theory. You can see several examples of this in the thread. Where do all these spec-obsessed brainlets come from?

Two things I hate the most:
>Vague questions like "could ABC evolve XYZ?" (the answer, almost invariably, is yes - given the correct circumstances). An interesting spec discussion needs more context than that
>Projects involving fantasy creatures. It's been done to death. It's rarely done well. It's not interesting. Most of the time it's just a cover for sharing furbait or cringeworthy fiction projects

Most species of primary producers use radiation (instead of light) as their power source to fix oxygen during respiration (radiosynthesis). Near to the equator animalesque plants climb giant fungal trees to photosynthesize. Some animals "hunt" these plants. I haven't actually decided on how the animals are, although they definitely all (at least land animals) possess some level of exoskeleton or chitinous plates that's primary purpose is deflecting as many x-rays and gamma radiation as possible, and soaking up the radiation it can't so it doesn't poison the organism's organs. The undergrowth and "grass" is more fungal descendents, single-celled yeast and slime-mold like organisms grow by consuming radiation, at least until the bright light of Loki led to photosynthesizers pushing into that niche. Around the poles only the hardiest species survive. The temperature stays around -100C before Loki and -40 after, the auras are so bright that there is effectively no night at the poles, although with the strong solar winds even the rest of the planet can get bright auras lighting up the night (and day). During "summer" the red supergiant lights up the nightside of Baldr to be even brighter than the dayside, and during this time the plants enter a period of rapid growth and reproduction.
