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.

>This was not always the case.
yeah, it wasn't always the case, but what Happened to all those non Carnivoran carnivores? Carnivorans outcompeted all the small to medium sized Creodonts and only the Hyaenodonts survived because of island isolation in Africa to become giants who didn't compete with Carnivorans for resources which allowed them to migrate back into Eurasia and persist for longer.
>megafaunal herbivores are much more diverse with (until humans showed up) ground sloths and proboscideans flightless birds like ostritches and rheas
We do not live in a world of island continents anymore. The Megalocnids evolved on an island continent where the native notoungulates had just been clobbered by the Grande Coupure and their lower metabolism allowed them to get big on fewer resources. By the time of the GABI, they were already heavily derived megafaunal herbivores making it impossible to muscle them out from that niche. Similarly, Proboscidean Afrotheres became megafaunal herbivores on Island Africa allowing them to take advantage of the decline of the Paraceratheriids caused by climate change. Not even going to address the ostriches and rhea comment, because I already stated I was talking about mammals guilds.
In Eurasia there are 4 genera of Cervids, 7 genera of bovids, and 3 genera of Chevrotain that are under 50 kilos most of which are not threatened and many of which are even smaller at under 30 kilos. The continuity of the Afroeurasian landmass means they will have the ability to travel almost anywhere in the Eastern hemisphere save Australia and other islands in a post extinction event world.

Again, like I said in my previous post, the Americas with the their small number of small Artiodactyls (Pudu, Mazama, and three different genus of Peccary) but diverse cast of Caviomorphs are the best place to hope for a mixed megafaunal herbivore guild.

I was criticizing the "Rodents inherit the earth" trope not saying megafaunal rodents can't exist

Speaking of which, god I fucking hate how stupid dinosaurs in Dragon Ball look.
>>
>>4949177
they're just wacky cartoon dinosaurs based on the pop culture depictions at the time, you have to remember that people ACTUALLY thought they looked like that more or less at the time. Plus there's nothing wrong with them being inaccurate in an anime or cartoon, outdated designs as inspiration for modern fiction is fun. Just look at primal, those designs were ALL outdated despite the fact that they're more recent than the design you gave as an example, but it's still fine - it's stylized, it's fun. It's also not spec evo, but it doesn't have to be.

Who is Jefrey (with one F) and why should you care?
He was found abandoned in some bushes late one night, filthy and covered in fleas back in mid-July 2024. He’s growing up fast, and enjoys car rides, climbing trees, fetching his ball, playgrounds, and capybaras. Some believe him to be a goblin or gremlin. He was named after the Pixies song “Space (I Believe In)”.

Jefrey suffers from severe ear-ectile dysfunction.

Originally posted him here back in July 2024 seeking advice for potential health problems due to his folded ears, some /an/ons wanted more of him, and so now you’re stuck with him.

1 - this why Latin binomial exists.
2 - it was probably named that after a type or early specimen compared with other weasels at the time of collection and description. There are many examples of this kind of weirdness. The northern mockingbird, for one, is found all across the United States, Mexico, Cuba, and only barely in Canada. It is only "northern" in the sense that it was initially collected in the carolinas.

The camera angle instantly makes me assume something went down right before the start of the video, or that the animal has a negative history with people. Maybe the local little shits threw rocks at it one time too many.

https://english.elpais.com/international/2025-02-14/too-many-capybaras-rodents-face-vasectomies-in-luxury-argentine-community.html

Nordelta is one of Argentina’s best-known gated communities. Built two decades ago on a wetland neighboring the Luján River, north of Buenos Aires, it now has 45,000 wealthy inhabitants, living in landscaped homes with views of lakes and streams. The habitat has changed in the past 20 years, but it is still a tempting one for one of its former occupants, the capybaras, whose numbers have tripled to more than 1,000 in just over three years. Most neighbors have gone from viewing these giant rodents with sympathy to reporting attacks on pets and destruction of plants. Many are now demanding something be done.

The Buenos Aires government has just approved wildlife population control plans that include selective sterilization and contraceptives with which they hope to reduce the rate of reproduction and solve the growing coexistence problem.

Cantón adds that the biggest coexistence problem occurs with dogs because both dogs and capybaras are territorial animals: “People reinforce the fences of their houses to avoid confrontation with their dogs and also altercations involving children because although the capybara is not aggressive, a female with young will become aggressive if approached.”

Some environmentalists are calling for no action to be taken against capybaras and, instead, for a law to be passed to protect the wetlands and prevent any construction on them, questioning the environmental sustainability plans that allowed neighborhoods like Nordelta to crop up. Others point out that there are people who want to live in nature, while wanting to get rid of its natural inhabitants, whether they be capybaras in Nordelta or foxes in nearby neighborhoods.

Why are vegan animals so big?

>>
>>4949867
>Also we'll never know how orcas hunted them.
Probably with some difficulty. Isolating the young from the adults and then going after them, maybe. That'd match the descriptions we got about their behaviour:
"Steller's sea cow may have exhibited parental care, and the young were kept at the front of the herd for protection against predators. Steller reported that as a female was being captured, a group of other sea cows attacked the hunting boat by ramming and rocking it, and after the hunt, her mate followed the boat to shore, even after the captured animal had died."
Steller's sea cow was ridiculously big. Two, maybe up to three times the weight of a male adult sea elephant. And Orcas have difficulty with hunting those:
http://eleseal.org/kw/kw_hunting.html
Getting mobbed by half a dozen 5- 10 ton animals while trying to kill one of them through its ridiculously thick blubber and unable to drown it because it's buoyant would give even an Orca pause, I think.
>>
>>4949908
True, but obviously there was a massive intelligence difference between Orcas and Steller's Sea Cow.
