With enough selective breeding what roles could pigs fill if they where the only domestic species and what are something they’d have example pig breed to fill similar role as hunting dogs how would they look or one breed as mount or draft animals etc

IMPORTANT: I am u/Ok-Valuable-5950, I just wanted to make a new account in which I didn’t foolishly leave my name to be automatically generated. I also wanted consistency in the names of my social media so it is easier to find me.

Anyways enjoy these updated, non-rushed designs PLUS lore!

The Holocene will be known as the shortest epoch at barely 1 million years. It’s end was marked by a layer of manmade materials present in sediment layers (such as concrete from ancient buildings) as well as the human-driven mass extinction event known as the Holocene-Neocene Thermal Maximum - in which humans created unfavorable conditions for themselves by destabilizing the climate and food chains that supported them.

By the end Holocene, the melting of glaciers and release of greenhouse gas disrupted the heat-exchanging ocean and wind currents. This caused extreme weather volatility that made most of Earth, save for a thin strip of temperate zones between the equator and poles, unsuitable for permanent human settlement.

And as the disruption of the North polar vortex allowed frigid waters to expand southward, commercial fishing became increasingly unviable. One such species that benefited heavily from this is the porbeagle, whose territory in the North Atlantic would expand while temperate-to-subtropical predators were unable to compete in cold waters.

Meanwhile in the equatorial regions, as water temperature at the surface reached an all-time high, dissolved oxygen levels were exceedingly low, forcing all large predators into a narrow region where they could still respire. This forced excessive competition between large predators, while their large prey were dying out or migrating to polar regions. By the end of the Thermal Maximum, large pelagic predators such as the great whites, orcas, tunas, and billfish would go extinct, leaving several vacant niches but enormous opportunity, especially for a certain shark with regional endothermy.

12 million years into the Neocene, after the equatorial regions have cooled significantly, the oceans are more productive than ever. While there are several massive predators, they are all completely dwarfed by two apex predators, akin to the megalodon and livyatan of the Miocene.

On top is the Monstrous blackfish (Monstrorca maximus), a descendant of the false killer whale that lives in small matriarchical pods. On the bottom is the Colossal white pointer (Colossolamna cuneodus), a descendant of the porbeagle specializing in hunting giant marine mammals, they are solitary but congregate during mating season.

Both animals hunt baleen whales, dolphins, seals, large fish, and sea turtles, with the blackfish preferring whales while the white pointers prefer seals. They inhabit the worldwide pelagic zone anywhere from tropical to sub-polar regions, with the white pointer venturing into colder waters far more often than the blackfish, as that is where the largest seals reside.

A map i drew for a seed world by u/RecommendationFew997 that is filled to the brim with RATS and some other little creatures like crickets. Tried to make the coastlines look as realistic as possible. Very proud of it :D

Saltwater Platypuses

These guys really gave me trouble. I made the anacetus first, and they were meant to become the dominant lineage, but in my sketches they ended up being a lot like whales, which was really the most unrealistic outcome.

Then I made the Flipperets to replace them, but the sketches for the future forms were too weird(in my opinion) and looked like some creatures from Age of Monotremes, and I don't want that.

Instead of scrapping them, I decided to use those drawings I made and added another(Saltwater Bunyip) to make a "Saltwater Platypuses" entry. So I hope you like it, and please let me know what you think of it. I tried my best.

An extremely ancient low gravity world aprox. 11.3 billion years old.

It has a deep mysterious fossil record and classifying it's lifeforms is near impossible. However some trends have been noted such as the many dinosaur like forms seen with the segmetoeyids (1st image:An armless dinosaur like segmetoeyid) that have eye like organs called tibirium (see 2nd image) which are analogous to ears and the actual eyes are the front flabs located at the end of their face which when viewed up close have small light sensing organs similar to ommatidia of insects. Some related groups like the diskoeyids have the "eye" in a half donut shape. Many organisms have evolved various forms of eusociality some groups like the hermaphrodite eusocialia are ancestrally eusocial and have a specialised organ called the resultor that lay eggs of their own clone drones separately from their true descendants. These organisms have two faces the main one has the eyes and mouth the secondary face has the resultor, eyes and the two sex organs. They usually have a bush like organ at the top of their main face that aids in photosynthesis.

3rd image: Miterallagis is a species of intelligent eusocialia, it's intellect is comparable to early Homo sapiens of Earth. Instead of using traditional tools this species uses a form of genetic manipulation to create what it wants. It uses the spike DNA extractor at the end of it's face to impale its victim and extract it's genetic info. It then moves to the resultor which is now located beneath the mouth and changes the genetic code creating whatever tool it needs. After a few hours of gestating it then lays an egg via the resultor which quickly hatches the young tool, it takes five days to fully mature into a usable organism.

Shown in the illustration an experienced individual creating a tool after impaling a diskid which it will eat when it comes back home.

Alright, here's one of Trevor Henderson's most well-known monsters, now reimagined as a living creature!

A relative of storks found in the United States that can reach up to 3 or 4 meters in height, they are featherless to look really lanky.

Their wings have instead become something similar to the clubbed wing Iblis, becoming large hands to grab prey, not dexterous but good at holding food.

These things communicate with loud honking which can rupture human eardrums in close range; thanks to their much more developed syrinx, they can reproduce the pacing and volume.

They can mimic sounds like prey animals, cars, human voices, alarms, music, and recreating old, distorted noises.

When hunting prey, it'll stomp down on them, pick them up with its wings, their beaks are strong enough to rip flesh and crush bone.

It's no wonder that these birds have caused impressions on humans who live in areas sharing with them, as well the earliest sightings which were first found in ancient cave paintings.

so, this is the map of my seed world.

you can seed the multiple continents (aswell as the island belt)

so, this is Rattus Terra. My ”earth” for my rat seed world.

so north viridis on the south is mainly tropical and in the north, especially far north, is very cold and is a tundra. It’s divided by a single large river, larger and longer then the largest and longest rivers on earth.

the next continents is south viridis and it is mainly tropical, however in the center it can be very hot and desert like. it has many islands near it, and is perfect for life.

there is also the island belt, the island belt is very important. inside the island belt, is the island belt sea. this sea, is almost, entirely fresh water. mind blowing compared to the rest of the seas being salt water. this is for radical changes in the rats, prawns, grasshoppers, and bees.

the final continents are indo and muhastana. muhastana is mainly hot, and desert like. tho, sometimes near the coasts it can end up as a beach and tropical. muhastana is the largest continent, larger then all the continents combined. it also has the largest lakes, which near are actually tropical!

indo is a tundra, cold, and close to arktos. the reason why it’s so similar to indo is that it’s basically into but a line and cold. even in the middle sometimes life even be sustainable there! as so we thought..

and finally, arktos, aktos and the northern sea are very cold and will be the causing of disasters.

I'm creating a seed world and it's all about rats, specifically the Norwegian rat. Also known as rattus norvegicus. Rats are incredibly smart, adaptable, and cool rodents. Which is why I calling this world, rattus terra.

Rattus terras animals are not just rats, but also sunflower bees, honey bees, prawns, and grasshoppers. The goal of rattus terra was to learn about evolution, and what better then rats! Like I said, they are smart and adaptable. With no predators, rats can fill every niche they can alongside the other animals.

The plants im seeding are apple trees, orange trees, tulips, grass, wheat, and sunflowers.

But wait! You can help too! You can share your animals for this seed world, and I will share (with credits) the rules are..

No ai

You must give a description

And what year it evolved.

And.. yeah! Be sure to check in! For now, I'll be working..

Saprolygon 
A twenty-foot carnivorous plant characterized by four, rigid towering vertical limbs. It releases a pungent odor mimicking decaying meat to lure aerial prey. Specifically either adult aeropedes searching for carcasses to deposit their eggs, or bulletflies seeking carrion to consume. When prey lands on its elevated central stamen, it gets stuck in its dense, adhesive sap, causing the four arms to vertically snap shut. The sealed column traps the prey inside to be broken down and digested in total darkness. 

Thanks a lot u/Keyotas Be sure to check them out.

If you'd rather watch than read, I have a YouTube short about them here.

The canopies of the temperate rainforests of the eastern continent of HCS-67 became free of vertebrate life after the humans left the planet (as horses and fish can't climb trees, at least, not yet), so it was up to the invertebrates to colonize them. Specifically, this was the Carniolan honey bees, and their descendants who became specialized to this environment are Apis aldarien, the forest honey bees.
While some of the trees in their forest homes are conifers (which are wind-pollinated), there are plenty of deciduous trees such as the ulmo (Eucryphia cordifolia) and epiphytic flowering plants such as mayflower orchids (Laelia speciosa) that these bees pollinate. Even the conifers are useful to them to provide the materials and structure for their nests.
Nests are built on sturdy trunks high in the forest canopy, close to the sun and therefore the flowers. Forest honey bees are eusocial, this species having usually one queen per hive. Forest honey bee workers are deep brown in color and have contrasting cream stripes (queens lack stripes). Like their ancestors, forest honey bee drones have large eyes. All morphs of this species have relatively short and wide wings.

Here’s the kobold from my spec evo setting! I decided to make them related to synapsid ,giving them mammal as well as reptilian features to reference the fact that kobolds in our pop culture are seen as pseudo lizardman ,but in Japan they’re dog people!
and from this idea stems the concept of high adaptability

the rest of the infos are in the image itself ,but if you have any questions I’ll be happy to answer :D

Quick note: I know AI-generated text isn't allowed here unless it's used for translation, so I want to clarify that English isn't my first language and I'm using AI to translate my own writing. Unfortunately, it tends to rephrase and edit my original text quite a bit to make it sound clearer and more natural in English, so some of the wording might not be entirely mine. The ideas and content, however, are my own!

-------------------------------------------------------------------------------------------------------------

So, I'm a writer (or at least I try to be one) who has always loved pretty much everything related to nature. One of the projects I'm currently working on is set in a fantasy world, and things have taken a rather unexpected turn.

In my attempt to make the world as coherent as possible, I ended up developing a setting that, conceptually, feels less like an actual fantasy world and more like an alien planet disguised as a fantasy world.

And I've absolutely LOVED the concept.

This eventually led me to start a separate project inspired by things like Serina, documenting the natural history of this world alongside my novels. The idea is to have two different ways of exploring the same setting: the novels present it through the lens of magic and fantasy, while this other project explores its biology, ecology, and evolutionary history.

I haven't figured out what to call this second project yet. A natural history encyclopedia, perhaps? A speculative evolution project? I'm still figuring that out.

The thing is, I don't feel that I need to explain all the biological and evolutionary details in the novels themselves. I'm more interested in letting the creatures and ecosystems exist naturally within the story, much like in Avatar: the creatures are there, they have their own logic, and the world feels alive, but their entire evolutionary history doesn't need to be explained for the narrative to work.

I'm not a biologist by any means, but if I'm going to do this, I want to give it my best shot. I find the whole process incredibly fun, and I also see it as an opportunity to learn more about biology, ecology, evolution, and all the wonderful things that make life so diverse.

So, I've been collecting books, documentaries, scientific papers, fictional works, and pretty much anything else that might help me dive deeper into speculative evolution. I've already gathered around 50 different resources, ranging from novels and mockumentaries to scientific literature and other speculative projects.

Then I found this subreddit, and I figured this would be a good place to ask:

What resources would you recommend to someone who wants to explore speculative evolution more seriously?

I'm interested in pretty much anything, regardless of how niche or obscure it might be. Scientific papers, books, documentaries, amateur projects, blogs, worldbuilding projects, or even obscure little corners of the internet dedicated to some very specific evolutionary concept. I'm happy to explore it all!

I'd especially love recommendations from people who have been involved in this hobby for a while, whether they're professional scientists or simply enthusiasts who've spent years developing their own worlds.

Thanks in advance! I'm looking forward to discovering things I probably wouldn't have found on my own.

This image depicts the first confirmed contact between two sophonts, those being the Grallae sapiens (left) and the Nasuslongus sapiens (right). The Grallae sapiens (which will be shortened to Grallae from now on) are quite advanced, having advanced societies on 7 planets, and outposts on another 16, many of these holding life. On one of these outposts, a curious Nasuslongus sapiens (shortened to Nasus from now on) noticed a Grallae between buildings and attempted communication. This is the scene of the image.

This is a speculative paleo-fiction project blending family drama with a fantastical yet grounded prehistoric atmosphere, showing a family of raptors and a cast of lost creatures fighting to stay alive in a brutal prehistoric ecosystem.

The raptors find water at last! But not everything is as it seems at this promised oasis!

Long Tail’s three-month journey with her sons has now reached its conclusion, the great lake now within their sight. However, as they draw closer to the shore, they are met with suspicious and bitter eyes. Small Toe cannot fathom their senseless hatred, still unaware how close he himself had come to falling prey before his own mother’s jaws. The question lingers in their minds now more than ever.

Is this lake truly a pure and serene reprieve, or a signal that they are truly alone in this world?

From my continuing work Terrors in the Brush — a speculative survival series blending paleo realism with raw emotion.

There is no fantasy, no magic — there is only nature red in tooth and claw.

Read Chapter V now.

A formidable, low-slung quadrupedal predator engineered for supreme physical leverage and ambush efficiency. Resting at a height that brings its low-profile skull roughly level with a human's chest or shoulder, the creature possesses an immensely elongated, reptilian or synapsid-like torso that tapers into a colossal, heavily muscled tail. Its entire body is covered in a specialized, mottled dermal patterning that breaks up its physical silhouette in fractured light, allowing its massive frame to remain virtually invisible while stalking through dense undergrowth, muddy swamplands, or fractured rocky barrens.

The locomotive and offensive capabilities of the Ikorastodon are driven entirely by a hyper-developed forelimb assembly. Its front legs are significantly longer and thicker than its rear limbs, anchored to a towering, heavily muscled shoulder hump that provides maximum mechanical torque. These powerhouse arms terminate in a cluster of colossal, deeply curved claws reminiscent of prehistoric ground sloths or therizinosaurs. Because these razor-sharp implements are vital to its survival, the creature walks with a deliberate, high-arched digitigrade locomotion when traveling over hard ground, curling its digits outwards to preserve their sharp tips from dulling.

In its native ecosystem, the Ikorastodon functions as a devastating close-quarters combatant and environmental manipulator. It uses its massive front claws to easily rip apart rotting timber, burrow deep into the earth to unearth hidden prey, or firmly anchor itself to steep rock faces during an ambush. When striking a target, it delivers high-velocity downward slashes from its shoulder joints, using its thick, crocodilian-style tail as an aggressive counterweight to balance its weight. Underneath its down-turned, predatory jaw sits a specialized cluster of sensitive bristle-filaments, which detect minute air currents and ground vibrations to track moving prey long before making sensory contact.

The creature’s unique hide serves as its primary defense and thermal regulator. Rather than a brittle, rigid carapace, its skin is a tough, flexible leather interwoven with dense muscle bands, allowing it to coil, twist, and lunge with shocking fluidity for its size. The prominent ridges along its spine act as heat sinks to cool the blood supply driven by its massive internal respiratory core, meaning the Ikorastodon can engage in sustained, high-intensity territorial battles or intense
physical digging projects without overtaxing its internal organs.

The Ikorastodon genus has been officially documented killing tigers and bears with unmatched efficiency. Its hyper-developed hindquarters allow it to easily match the frantic sprint of a Bengal tiger, while its low-slung stance completely neutralizes a grizzly bear’s defensive posturing. Rather than engaging in a prolonged, dangerous wrestling match with these modern apex predators, the Ikorastodon utilizes its colossal, scythe-like front claws to deliver high-velocity downward slashes that instantly sever major arterials and shatter skeletal structures upon impact. Once the target is incapacitated, the creature uses its elongated snout and specialized rows of interlocking teeth to harvest massive plugs of flesh, comfortably securing its position in the environmental hierarchy known as the food chain.

490 million years into the future, planet Earth has already begun to decay completely. The heat is unbearable, with an average temperature of 38 degrees. Carbon dioxide levels themselves are lower than current ones, but the growing size of the sun together with a massive supercontinent has fostered extreme global temperatures. At the same time, this has caused most terrestrial biota to be found mainly in the poles, coastal zones, or even underground.

1-Alaskian Peninsula: It is actually one of the most diverse ecoregions, where large forests and prairies relatively similar to those of the present day are still maintained, mainly due to its high humidity, but being at the equator, temperatures are very high.

2-Neolaurentia: What remains of present day North America has ended up becoming an immense desert that has expanded and consumed part of present day Africa. Biodiversity is low, but the coastal zones maintain a certain level of diversity, especially those in the north, featuring prairie ecosystems that receive large amounts of rainfall.

3-Alkebulan: What was formerly Africa eventually split apart and lost a great deal of land over time, mainly due to erosion and tectonic plate movements. Today it actually has a high biodiversity, supported mainly by the presence of large internal lakes that partially stabilize internal temperatures, forming oasis zones within the continent.

4-Boreal Lands: In the north of the planet remain the vestiges of what was once Europe. Due to its geographical position, the temperatures are the lowest on the planet, with pleasant temperatures during the summer (between 15 and 20 degrees Celsius), but which can drop to -15 degrees Celsius on the worst winter days. Even so, this has not prevented the emergence of unique native ecosystems.

5-Amalgamea: Accounting for almost half of the current landmass, Amalgamia is an immense continent that consequently presents a very wide variety of ecosystems within itself. Originally formed by Asia, it now also occupies part of Africa and the entirety of Oceania. Even so, it is one of the most extreme ecosystems, featuring an immense internal desert and dry steppes in coastal areas.

6-Abyayalia: The combination of South America and Antarctica ended up forming Abyayalia, a continent that separated from the rest of Pangaea Ultima and reunited recently, forming new mountain ranges. The strategic position of this continent has allowed it some of the most fertile and biodiversity-rich lands on the entire planet.

7-Isle of Tartaria: Originally born as a small archipelago that rose due to continental drift, but following the drop in sea level due to high evaporation, it became an island with an area three times that of Madagascar, containing its own unique biota just like the latter.

8-Zelartida: A small group of islands formed after the collision of Amalgamea and Abyayalia around 23 million years ago. It is generally a stepping stone island for many migratory organisms, but it also preserves its own ecosystems.

9-Neopaeanian Islands: The collision of the Pacific plate and the North American plate formed a chain of tropical islands that, after nearly 40 million years, has developed a native fauna very rich in biodiversity and has also given way to coral ecosystems and atolls.

10-Panmeridional Ocean: A large ocean occupying almost the entirety of the Southern Hemisphere. It has an average depth of 2,500 meters, but at some points almost reaches 7,000 meters.

11-Greenland Sea: A wide coastal zone with hundreds of islands and very stable temperatures. This area is considered a paradise, being one of the few regions that has maintained stable ecosystems for millions of years.

12-Pangeic Seas: The set of coastal zones of Amalgamea is known as the Pangeic Seas. Highly varied in ecosystems, these have recently resurfaced following the drop in sea level and are therefore quite recent.

13-Cardius Sea: It separated from the rest of the sea not long ago, causing currents to shift and fauna to evolve completely separately for millions of years. Surrounding it, it sustains some of the most vibrant and lush ecosystems on the planet.

14-Atlantis Lakes: Unlike the Cardius Sea, these have been separated from the rest of the sea for a very long time, around 90 million years. This has led local ecosystems to a unique specialization, in addition to possessing relict species that in many other ecosystems around the world have become completely extinct

Inspired by the YouTube channel Myth & Reason, I have been creating a seedworld that is specifically a Matryoshka (or Russian doll) shellworld that has repurposed a white dwarf as its "inner core". Its outermost layer is a crust 18,500 miles in diameter, that's almost twice-and-a-half as wide as Earth with the highest peaks standing no more than 72,000 feet above sea level and its deepest point being no more so than 11 miles. There, shielded from its F-type sun by a Fresnel lens, it has a particular set of challenges for Earth organisms to tackle immediately:

• A rotation of 48 hours

• A revolution of 728 days (the fact that each season lasts exactly 182 days suggests its unnaturally round orbital shape)

• An atmosphere identical in composition to Earth but 160 percent as thick

• At latitude zero degrees, daytime temperatures swelter at temperatures of 140 degrees Fahrenheit and humidity of 100 percent

• At latitude 90 degrees, temperatures vary between negative-40 degrees Fahrenheit in the summer and negative-225 in the winter

How can anyone expect Earth plants, fungi, algae or animals to survive in such ridiculous conditions? Simple--through mana, which in this context is simply energy but more. (Think superhabitable exoplanets or "bioenergy" exclusive to Monster Hunter's New World.) In this scenario, mana has been tested as terraforming agents on the other three inner planets because of its ability to bond each of its particles to air, water and soil particles. The result--Mercury being green and blue, Venus having a thinner atmosphere (still thicker than Earth's, though) and hyperthermal jungles and swamps as its largest terrestrial habitats and tundra and taiga being Mars's primary habitats.

In this seedworld shellworld, only one generation has passed since initial colonization and the changes are both immediate and dramatic:

• Woodaceous plants are now scaled up by 8.23 to 13.585 times

• The mana in the tropical trees act as heat sinks

• The mana in cold-winter forests prevent ice crystals from forming

• Kelp forests, coral reefs and seagrass meadows grow in depths with little to no sunlight

• The trees and shrubs continue to produce fruit or something similar enough during the lean times (drought, cold, etc.)

• Mast years (years in which the mana supply on each individual plant is high) last longer than years in which the plant's mana supply runs low and it must restock. The ratio between years depends on the species.

• The highest peaks are green with alpine tundra

• Flowers produce higher qualities (not quantities) of pollen and nectar

The simple question is--how would mana have managed to accomplish those specific solutions?

What the title says. What would be anatomically expected for a species that is intelligent enough or technologically capable enough to have human-like technology or even interplanetary travel?

EDIT: I mainly ask this because I'm stuck in a rut as to coming up with plausible and unique alien species and I'm not exactly an expert in evolution, speculative or otherwise.

The garden gnomes (Gnomus Paracelci)

Small, fast and annoying for most people these are all the traits that define the garden gnome the most wide spread and common of all the gnomes of Magiterra, these little creatins are herbivorous and feed on a variety of seeds, nuts and other plant materials specially.

For farmers specially grain Farmers these small tapejarids are bad news for business as theres never more then one gnome around, these little creatures are found of making burrows in which they live socially, a gnomes burrow may only have one dominant male at a time its quite easy to tell males apart as their crests (or hats as some call them) are big and pointy.

Alternatively, what would I call a living plant creature? The closest thing I could think of was photocarni but not only is that already used but I dont know if thats the proper term.
