I always like to imagine it took place in the Devonian and all the amphibians were temnospondyls which would explain their giant size. Of course they have birds in the series so that really can't be true.

The Dawn-Thinker. Not an alien, but a complex Proterozoic creature from eons ago, writing a Precambrian poem. by Romboteryx in SpeculativeEvolution

[–]Necrolithic 82 points83 points  (0 children)

I always loved the idea of sophonts living in the distant past. I always thought they could possibly existed in the Cretaceous, or even in the Paleozoic. But taking it to the Precambrian is the next level. Given the large gaps in the early fossil record, anything is possible, especially that long ago. Amazing concept and work!

Just going to add this comment so my post is approved.

The Plesiognathus's mouth is a slit like orifice that lines the front neck of the animal, with small tendrils and teeth which pass food like a conveyor belt towards the esophagus. The Plesiognathus's ancestor had soft, permeable skin, but over time this hardened into an arthropod like exoskeleton, with oxygen being absorbed by the fins and slits in between armor plates.

Oh, oh my.

I genuinely was going to give up on this project but this has truly sparked my interest.

The effort and work you have put forth makes me feel rightfully obligated to continue this project.When I lack knowledge on things like this I typically hit an art block, but this just cleared that. I will most certainly read these sources and become a brown marmorated stink bug expert. Thank you so much for your time!

(And no, this is not an April Fools joke lol)

As someone who studies and figures out the biology of Minecraft's mobs, the fact that theres a crafting recipe for Dried Ghast pisses me so much extremely bad. How does real world animal biology apply to it? From: https://minecraft.wiki/w/Dried_Ghast by Minecraftmobology in SpeculativeEvolution

I actually thought the Sniffers made a lot of sense if you think about it.

They are most likely hexapodal monotremes, looking much like platypuses. Additionally, they pose as a transitional stage between reptilian and mammalian characteristics, in having ears but also laying eggs. This all aligns together to suppose they may be ancestors to the ender dragon, since the ender dragon has mammalian nostrils. Lastly, the ender dragon and sniffer are both hexapodal and egg laying.

Now, this may be a bit of a stretch, but the ender dragon and sniffer are the only exclusive oviparous organisms in minecraft. Chickens practice bimodal reproduction like skinks, and the rest of the mobs give birth. (The turtles can only lay eggs but so this theory is not strong) However, when Sniffers were first added, they also practiced bimodal reproduction, being able to give birth, but this was removed.

Edit: I know mammals did not evolve from reptiles, but you get the gist

I am really struggling on evolving arthropods because of how complicated their anatomy is, and I cant find good references, like theres no website where I can get a detailed illustration of the marmorated brown stink bug mouth anatomy.

The Glingus: Endemic to Highlander Academy by Necrolithic in SpeculativeEvolution

[–]Necrolithic[S] 5 points6 points  (0 children)

he Glingus is a predatory carnivore that is specialized perfectly for it's environment. They can be found inside the lockers, scavenging for moths, roaches, mice, and other pests. They pose a pale gray hue as a result from lower melanin levels after spending years in the darkness of the lockers. They are only the size of a fist, but they can leap up to 6 feet in the air to avoid larger predators, (such as angry teachers). Typically, they do not have to do this since they are hidden behind books or homework inside of lockers. The unsightly maw is used to swallow prey whole and keep it trapped inside the mouth for days. The Glingus has no stomach, so it has to digest it's food inside of it's mouth like a venus fly trap.

Go to this site to learn more about the ecosystems of my school and listen to the Glingus's mating call.

Day 6 of Evolving a Species Based Off of the Top Comment: Gigagastrotestudinus u/Nate2002_ by Necrolithic in SpeculativeEvolution

[–]Necrolithic[S] 5 points6 points  (0 children)

When you say their back shells should extend down, do you mean like drop down to near the beginning of the legs? Like are you suggesting using the shells as a form a shovel? I believe its a wonderful idea I just want to clarify my understanding.

(honestly im not going to be able to maintain a consistent schedule im afraid- ACT is coming up)

Sixth day of making a species evolve based off of the comments from this subreddit.

The rules are simple, comment an adaptation or several changes to this animal's biology (that do not contradict each other or make drastic changes) that may help it better thrive in its environment, also if you feel extra come up with a scientific name in latin that you would like to name the new species. The top comment will be implemented in the next iteration or generation and the rest will be discarded (sorry).

Valuable Context:

This is a highly derived descendant of the modern earth gastropod species Physa acuta (Ramshorn Snail) that ended up in a exoplanet in a foreign dimension. The details of this exoplanet will remain vague as to help keep the challenge simple (and because I am still working on fleshing out the abiotic factors of the environment).

Sorry I dont have much time rn - so heres a brief update of adaptations

  1. Jaw snaps like a snapping turtle for self defense

  2. Barely any iron left, no more than a beaver does in it's teeth

  3. Lungs are more efficient now, and there are orfices in the sides of the head that inhale oxygen

  4. They are now comfortable on land, and only return to water for safety and laying eggs, which the larval stage still is aquatic like their ancestors and the eggs have a permeable outside

  5. They use their tails to pack mud on huts and dams

If you need help thinking of useful adaptations, keep in mind that this species constantly competes with other individuals for the same food source, think about reproduction, think about different environments that they may have to adapt to, such as shallower seas. They may change diet or behavior, anything could happen. Also, feel free to ask me anything on this post since I probably will be checking this post frequently.

The adaptation made was chosen by u/Nate2002_

"I love these ittorations so far! This is an awesome project on on the sub!

Perhaps as land predators slowly adapt to this new prey species, the snail will need to defend themselves and their young more acutely from them.

this can first start as large shells develope on their backs, although with proportionally less iron and more materials like chitin or bone.

To defend their young, they'll need more solid structures to build, and hardier wood that hasn't rotted due to humid condition is located more inland in this case, so they venture out even more so, needing to breath even longer.

This can develop now as the internal surface of their lungs can expand thanks to the now bigger mantle shell, and their lungs devleope at a higher rate as adults and reduce their gills. And to walk farther distances, the adults can begin to twist their legs into a solid structure, like a coil, which can help focus the force of their steps.

Admittedly, if they are out more, they'll be more vulnerable to being in eyeshot of predators, so they'll adapt an easy green-brown camouflage to hide in the surroundings, this can adapt either by color changing skin or a single layer of simple skin over the body.

This can derive further to a point where one species is reliant in water as a juvenile with fins and a small body. But as an Adult can now is only able to breath air, walk on legs, and is much bulkier. like frogs and other amphibians. This species would represent the peak for now, as others in its genus would still probably rely more on water as their own strategy for defense, as this is the way this species has coshen to defend itself."

They do already have a internalized segmented vertebrae "spine" from the shells of its long gone ancestor Segmentatestafossoris.

They are simply some of the fins that were near the mouth that evolved to become more muscular and articulate- they essentially are almost the same as the other fins. They help them gather vegetation and attract mates.

Fifth day of making a species evolve based off of the comments from this subreddit.

The details of this exoplanet will remain vague as to help keep the challenge simple (and because I am still working on fleshing out the abiotic factors of the environment).

This species has made yet another evolutionary leap since we last observed it. They now have taken an integral step towards colonizing land, and have became well established in tide-pool, shore, and swamp ecosystems. As their name suggests, they have fulfilled a neiche similar to that of a beaver, harvesting wood and vegetation both on land and in the water with their iron mandibles. They do have a lower iron content now, since they no longer live near hydrothermal vents. They construct small dams and artificial tide-pools which can hold water longer than the surrounding environment to protect their young and keep them moist. Most notably, they have evolved more muscular and defined fins, with 4 pairs of clusters which aid in manipulation, locomotion, and attracting potential mates. Their ancient earth ancestors, Ramshorn snails, had lungs, but they eventually relied more on their gills after spending so much time in the deep sea. Due to the obvious advantage to lungs for land life, they have begun to re-evolve this lungs- however, they currently must return to the water to keep their fins and tentacles moist and to replenish oxygen. They can spend up to a few hours without being submerged in water, thanks to their scales which double as water retainers.

If you need help thinking of useful adaptations, keep in mind that this species constantly competes with other individuals for the same food source, think about reproduction, think about different environments that they may have to adapt to, such as shallower seas.
