Crabs. https://en.m.wikipedia.org/wiki/Carcinisation
Multiple different species have evolved into crabs. Apparently it's kind of a mystery.
I think they're the perfect organism.
I'm only 1/4 joking.

I’ll bet 90% of people commenting on the internet immediately thought: “octopi!”
Twelve ponderous paragraphs into the article, this brilliant scientists finally says: “octopi.”
Crows! Oh. Are we taking guesses? Dogs! Any creatures who have lived close with humans? Cockroaches!
My best guess? Probably another primate. Bonobos and Chimpanzees seem like the ideal candidate to take over the husk of Human civilization the quickest. Another species might have a shot, but then it's a question of how many millions of years it's going to take for them to evolve and if they can survive the cataclysmic events that will no doubt hit Earth in the meantime.
If not primates, I would bet on one of the following species:
Corvidae - Extremely intelligent, highly adaptable, tool-users, social, pass down their knowledge to offspring.
Canis Familiaris - Highly social, apex predators, genetically diverse, spread throughout every corner of the world.
Loxodonta - Extremely intelligent, highly social, adaptable, builders and tool-users, long lifespans.
It will be dolphin people!
I'd bet on racoons or some primate. They aren't going to get far though until there's enough continental subduction to reveal fresh metal and fossil fuel deposits, and that could take a very, very long time.
But they
- Have extremely short lifespan so a limited capacity to learn (1-2 years)
- Don’t raise their offspring, in fact after mating/laying eggs they naturally die, so no knowledge sharing
- Are extremely solitary and don’t have social bonds or do anything socially, so little communication/passing of knowledge
I’m not even convinced that intelligence is a requirement to be the dominant species. Intelligence is so expensive that nature rarely ever selects for it.
Trilobytes did pretty damn well for a hell of a lot longer than we have so far. I think we need a stronger working definition of “dominant” in order to judge any candidates.
But the reason he gives for them becoming the dominant species is their intelligence.
Sure well if that is a precondition of the conversation, we can talk about it. But IMO it may be a faulty assumption to go on.
On top of that, they might not even survive the CO2 and consequent ocean acidification. If humans were to get eradicated by some super plague, then octopi might still stand a chance. However, the points you mentioned mean that they are playing this game in hard mode when it comes to winning by intelligence.
I worked as an intern at a lab studying octopus vulgaris.
They are extremely sensitive to all sorts of things in the water. Keeping them well is very difficult. Although I would imagine if there are big but gradual changes in water environment, they would have a chance of adapting faster due to short life cycles and the fact that mating creates hundreds of thousands of eggs.
If we assume that they somehow survive all the way to the very moment when humans get a permanent ban to the Earth Server, then the changes should be gradual enough after that. The bad news is, humans love to play this game by recklessly exploiting every bug and glitch, so rapid changes (in evolutionary scale) are the norm.

Octopi would rule the world if they had any sort of generational data transfer.
Eighteen paragraphs of throat clearing to get to the point of the title.
It's the new norm. Worse when it's video format and, thus, hard to skim.
Sponsorblock and YT's "relevant metrics" or chapters are life savers lol.
It's unlikely an aquatic species can achieve technological breakthroughs needed to spread like humans can. It would be very difficult for them to build fires, smelt metal, and create the advances based off of those tools.
While they can be extremely smart and adaptable, it's difficult to imagine how a species like that could develop machines.
Sure, there's possible ways around it, like natural vents and geothermal power, but why would they utilize these resources without a benefit like cooking?
Shells or coral could serve as early tools, but (just my opinion) I feel it's a little human-centric to assume fire and metallurgy are required to progress. Just because we did it that way, doesn't mean another species would have to.
I've spent a lot of time thinking about this exact subject, and I dunno. As much as I consider it, as abstractly as possible, I have considerable difficulty finding an alternate route to significant human-like dominance. Fire and metallurgy are just so incredibly useful across so many domains. I challenge you to present a reasonable alternative route.
Yeah, but we did all of our discoveries as a land-based species. It's totally possible some water-based species would find other crazy useful early techniques, then eventually discover stuff like "fire" much further down the line with access to more robust technologies. Their scientific roadmap would look very different from ours, but there are so many weird tricks and techniques that would eventually lead towards some of the dominating processes we have.

Such as?
Even then, they are still short-lived, non-social animals who don't raise their young. How do individual discoveries compound into robust technologies?
Fire and tools were what we needed to become the dominant species, as they gave us power to take down the larger megafauna.
whatever comes after us will have to make due with whatever crap we leave behind. There wont be enough natural resources left for them to use if they want to do anything larger scale or advanced
A symbiosis between octopi and dolphins 🤔

Their lifespans are very short and that whole ocean acidification thing might be a problem.

They are marine which makes fire impossible which severely limits industrial advancement. Similarly they are not social animals which negates a lot of the division of labour advantages of a society. While a species of octopus might advance intellectually to ponder its own existence I doubt it could achieve the infrastructure necessary to significantly control its environment.
They could use the underwater volcanoes to smeltle the meltle though, thought of that? Checkmate.
We have terrestrial volcanoes, how far would human civilisation advanced if they were our only source of fire.
Don't forget that they only live 1-2 years. 3 tops. I think this is even more limiting than fire. And if evolutionary pressure leads to longer lifespans somehow, they must overcome the whole dying after mating thing.
True, also they do not raise offspring which means zero communication of non-instinctive knowledge between generations.
I think we will screw up this planet even more before the end. So, probably bugs.
Crows and ravens. Highly adaptive. At home in a deep forest or the remains of a burnt out city. Social. Predisposed to intelligence.
The whole concept of a "dominant species" is also a bit ridiculous and probably shouldn't be bought into whole cloth. If what we mean by "dominant species" is 'the most radiatively expansive single species before allopatric speciation takes over..", then pick any one of the many many invasive we've spread around the planet. Our intelligence has allowed for a massive and basically instantaneous geologic layer globally, but it's not something that can be handed off in the way that a vasculature did for land plants or the ability to decompose cellulose and lignin did for fungi.. unless we want it to be.
If you really want intelligence to make it's mark on the earth we need a way to move it from our species into other species, because we're not long for this world. Move the genes specific to human nervous tissue and neurons into bees, ants, termites, any formian creature. That'll get this party started.
I think there's a solid argument to be made for ants as the world's dominant species. There are even supercolonies that span multiple continents. https://pmc.ncbi.nlm.nih.gov/articles/PMC3352483/
They will likely continue to thrive in the post-human global environment. Their success does not rely on human development (like, say, rats), nor are they severely threatened by human development (like...well, most things).
Was talking about this earlier with the s.o., we've both got pretty substantial biology training (phds, ms, bs etc). We both agreed that "dominant species" is a bit of a term looking for a definition, as in, it's not something extending from biology or ecology but rather something being imposed upon them. We were between nostoc and rhizobium, with fungi capable of digesting lignin in third place, for the most "world dominating" species, in the sense that those species, through their biology, have carved the planet into a place much more suited for themselves.
It strikes me that humans aren't even really doing that, but rather, we're selecting for an environment less suitable to our own survival. So I don't know that humans would even rank for dominance over the environment because we really don't have any sense of control over the matter, whereas, some other species clearly do.
Dominant at what?
Yeah, nature is not good with a "dominant" species. Not for the whole planet at least.
Ants. The hive mind structure will be hard to beat.
There is no hive mind. They use chemicals to communicate.
