We tend to think of agriculture as a human innovation. But insects beat us to it by millions of years. Various ant species cooperate with fungi, creating a home for them, providing them with nutrients, and harvesting them as food. This reaches the peak of sophistication in the leafcutter ants, which cut foliage and return it to feed their fungi, which in turn form specialized growths that are harvested for food. But other ant species cooperate with fungi—in some cases strains of fungus that are also found growing in their environment.
Genetic studies have shown that these symbiotic relationships are highly specific—a given ant species will often cooperate with just a single strain of fungus. A number of genes that appear to have evolved rapidly in response to strains of fungi take part in this cooperative relationship. But it has been less clear how the cooperation originally came about, partly because we don’t have a good picture of what the undomesticated relatives of these fungi look like.
Now, a large international team of researchers has done a study that traces the relationships among a large collection of both fungi and ants, providing a clearer picture of how this form of agriculture evolved. And the history this study reveals suggests that the cooperation between ants and their crops began after the mass extinction that killed the dinosaurs, when little beyond fungi could thrive.
Common Ant win. Just a daily reminder that Ants are much cooler than cats
Does your cat engage in agriculture ? Didnt think so
Wouldn’t know it with how efficiently my cat was fertilizing my bed the other day.
Dang this is cool. A model for surviving climate change: live underground and grow fungus for food. Is anyone seriously working on this besides the leaf-cutter ants?
Worth pointing out that the domesticated fungus in leafcutter ant nests is not found anywhere else in the world, it’s genetically distinct. When they start a new nest, they even carry a sample of the fungus for the new gardens as if they are maintaining the FLAME OF CIVILIZATION
did the ants domesticate the fungus, or did the fungus domesticate the ants?
Ants are fuckin cool. I wish the egg layers weren’t referred to as “queens” because it gives the wrong implication that ant nests are a monarchy and that the queen somehow rules them.
In reality no decision-making comes from the queens since ants will continue to dig nests, find food, and care for each other even without a queen. The nest just doesn’t have eggs to replace them.
Ants are really closer to being socialist collectives than anything. Food is divided evenly (although queens do get fed more, but only for the biomass needed to produce eggs) even the tiniest bit that is found is shared among as many as possible.
I like the ones that carry off and bury dead ants. I saw a video where someone wiped the compound they release when they die on one’s back and little guy was like “well guess I’m dead” and waited till he got carted off and thrown in the pit. Eventually it dissipated and he got back to work.
thank you ants. thants.
Some ants even pretend to be injured to get carried back by their nestmates, they just like me fr fr
The ant equivalent of pretending to fall asleep on the car ride home so one of your parents will carry you inside and tuck you into bed
You have the right idea but I gotta share my ant brainrot for a moment
Queens indeed do not rule nests and they are essentially the brood slave of a colony at worst, the colony’s sex-having consolidated into an individual at best. But Queens do make some big ass decisions when it comes to starting a colony, since they are the ones who, after mating (usually out in the open in a nuptial flight event), make the decision of where to dig the first tunnels of a new nest. They also care for the first generations very closely, even helping them out of their eggs and stuff, it rules.
Its probably worth mentioning though that this isn’t true across all ant species, since there’s a ton of variety. Some ants do no have morphologically distinct queens, as they are selected from among the workers in little ceremonies that scientists once though were dominance duels but now they think might be little cheerleading competitions to see who gets the crowd going best (awesome). Other ants don’t have queens at all and are parthenogenic, which has crazy consequences for the dispersal patterns of their offspring. And then you have the supercolonies with multiple queens which are worth their own effortpost
Tyranids farming ork biomass.
GW “super intelligent hive mind swarm” doesnt know agriculture meanwhile real ants farm.
The “hive mind” trope sucks ass, seriously, it misses so badly. It’s always some kind of “one mind, many bodies” thing even though that’s just a body, like the one your cells and neurons make up. The hive mind is, if anything, only possible when there are many individuals whose ability to independently gather and digest information in the group. It’s emergent from the shared dependencies of social animals. The most direct example is often ants because they can’t even survive without others to regulate their bodily processes, like they can’t poop right and die if there aren’t any other ants to barf food into in order to empty their second stomach. Their “hive mind” is something they make as a collection of individuals, just like with humans tbh (but that’s just philosophy in the end aince it’s hard to empirically test)
