some creatures evolved from crab eating frogs for a seed world project🌱

here's a bunch of creatures located in kelp forests or seagrass meadows on planet hal (a seeded planet)

This is not exactly part of any future project, but as concept idea inspired by somebody's brainstorm that I discussed a long time ago, I had the sketches for a while with vague description so I decided to at least flesh out a little more these future chameleons of a far away seed world.

In spec evo, there's a concept known as the "seed world" (or seed planet), a thought experiment where a planet capable of hosting life (usually from earth biology) is "seeded" with a few select organisms (and other starting conditions), and potential evolutionary-timescale outcomes of this are then speculated upon. For instance, what if there was a planet that was basically Earth as we know it except there's no vertebrates, and then someone adds a bunch of ducks? What niches would the ducks diversify into? Would any of them evolve into cool megafauna? What would it take for ducks to evolve into avian moles? Interesting stuff. But not what I'm doing here today.

Many of you will say that I was so preoccupied with the starting assumption that McDonaldland characters are species rather than individuals that I didn't stop to think if I should, and I agree. Anyway this is my seed world - "McDonaldland" - about 50 million years after a terraformed earthlike world was seeded with classic McDonaldland characters for an advertising stunt, part of a promotional tie-in with a movie about alien planets or something (records from this era are spotty at best). This stunt directly led to increased sales of McDonald's products for many Earth-years, but once the promotion was over the planet was filed away and forgotten about for around 50 million years.

We've got a towering therizinobirdie having a snack, a bunch of western lowland gorilmaces hanging out on a nice warm rock, and some apex predator descendents of fry kids fighting over a burgersnake, which we can tell is unhappy to be considered a meal. A trio of hamburlugos glide among the treetops, eyeing up the other burgersnakes as they slither away. Sadly, none of the lineages descending from clowns made it this far.

McScientists documenting this ecosystem after its rediscovery by McDonald's archivists are intrigued to note the example of convergent evolution on display with the "sentient hamburger" seed-species evolving into snakes. Anacondas and buns, together at last.

Should I make a seed world ? Also what animal species should I put in it 🫵 help

Native life!!! Ok so on Kteis 8b, or Ctitan, there was previously its own set of life, just microbial, but life nontheless. Multicellularity is only really in the colonial way earth bacteria can get (such as filaments). Though there is macroscopic unicellular representation, as on earth

This is Scalosia, theyve been just doing their own thing for about 4.6 billion years.

And below is the most prominent phylla and their information with little gags or visually shown info in the images

Dont worry they wont just bebrushed over as much as youd think, they will appear multiple times (extinction events, pathogens, symbiosis, etc). If something doesnt add up PLEASE tell me

for your consideration: mollusc based plant life

An introduction to Terra Psittacina: a budgerigar-focused seed world

Originally set up as an experiment in geoengineering by a technologically advanced human civilisation, the biosphere of Terra Psittacina has long since been abandoned, its organisms left to fend for themselves. The entire ecosystem was built around one species — the budgerigar, Melopsittacus undulatus. This is the story of those descended from the original few organisms that were brought to the planet from Earth.

The planet itself is very similar to Earth in size, axial tilt, and orbit. Its star is similar to Earth’s sun, but its moon is both larger and closer in orbit, giving the planet strong tides. The maps illustrated here show the planet's appearance 1 million years AE (after establishment). The top one is during the northern hemisphere summer, the bottom one is during the southern hemisphere summer.

At this point in time, most of the planet's biodiversity is centred around the two tropical continents — Reflection in the east, and Titan in the west. The northern continent, Precipice, has few inhabitants, as do the two large archipelagos — Chandelier in the north, and Debris in the south.

The climate is warm, but as plants take over the land it will slowly cool. Speciation has been extremely rapid in the first one million years as new ecological niches are filled. It is the early Eopsittacine, the first period of the Diapsidian Era. The world has just begun.
