The weight of all ants on Earth is roughly equal to the weight of all humans- aka there are a lot of ants. And can be found everywhere mammals are able to live. So they make sense as a food source
Your username makes me think you'd be a good person to ask:
Sorry, what? (Edit, this sounds like I don't believe you, but it is more that I am in disbelief!) Ants evolved from stinging wasps? Were they flying at that time? Or were wasps at some point non-flying and the 'wasps' grouping is a wide one like 'beetles' is?
This is such a fascinating space I know very little about.
I don’t know the answer to your questions off the top of my head, unfortunately, but they are most certainly answered in The Ants by E.O. Wilson. It’s a fascinating and artfully written book. I unfortunately gave my copy to a student, or I’d have found the relevant passage for you. (The biomass fact mentioned in a parent comment is mentioned in the book as well.)
Yeah I was surprised too! I don't actually know that much about ants or biology, but
- (1) ants fly!
well they don't usually fly, but they spread wings and fly during a "nuptual flight" to start new colonies [0]. I only learned this a few years ago when I moved into the woods and mass migrations of flying ants often.
From what I can see, all wasps fly, and I can't find anything saying their common ancestor couldn't fly. So since ants can partially fly, I think it's much more likely they evolved from a flying ancestor. They just lost lost the ability to fly most of the time and totally dominated the land niche.
Incidentally, living in the woods has also taught me that there are a variety of wasps that live underground like ants do. I used to think they all built open-air hives.
- (2) I made that comment mostly based on a paper [1] I found while googling around. According to the paper:
> The stinging wasps (Hymenoptera: Aculeata) are an extremely diverse lineage of hymenopteran insects, encompassing over 70,000 described species.... The most well-studied lineages of Aculeata are the ants... and the bees
This is consistent with what I've seen on Wikipedia. Basically ants, bees, and wasps are very closely related. The Wikipedia page on Aculeata [2] has a nice family tree that includes sawflies, bees, and wasps.
So yes, wasps is wide like beetles. But there are more beetles. Beetles get their own order, whereas stinging wasps, bees, and ants have an "infraorder", which I guess is like an order but smaller. The Wikipedia article on Hymenoptera has a family tree that shows the relationship with beetles [3].
srsly, granted I didn't add a ton of value to the thread, but if a simple gesture of gratitude for a needed moment of human levity results in downvotes and attempts at judgy put-downs, something's wrong here. please look at my comment history before deciding who belongs on what forum. I love this place and will accept whatever further karma hits come for mentioning karma in addressing this incivility.
Trees really aren't a good example of convergent evolution. The evidence tends more toward "all plants have woodiness genes, and sometimes those genes can be activated/deactivated".

> aka there are a lot of ants
This is true
And easier to predate on at scale than humans.
I was thinking maybe that's why the evolved stingers, but it turns out ants evolved from stinging wasps not vice versa.

You may not like it, but this is what peak mammalian performance looks like.
Ant eater pickup line.

wow, was that a misplaced and unnecessary barb.

At the end of all things, when evolution has reached its inevitable end, all that will be left is a war between ant eaters and crabs.
Ant eating crabs.
Crab eating ants.
We'll kill the ones that eat us and eat the ones we kill.
Crabs are already quite susceptible to ants, due to ants being small enough to swarm and attack the joints and gaps of the crab's carapace.
What about a crab made out of ants?
I can see the shear abundance of ants tilting the scale of evolution's nonlinearity.
Reminds me of Mitch Hedberg, ~"[Ants are] great if you're ever really hungry and want to eat 2000 of something."
A bit like [carcinisation](https://en.wikipedia.org/wiki/Carcinisation) for crustaceans
Another one is, believe it or not, trees: https://eukaryotewritesblog.com/2021/05/02/theres-no-such-th...
Trees really aren't a good example of convergent evolution. The evidence tends more toward "all plants have woodiness genes, and sometimes those genes can be activated/deactivated".
Fruits are, though.
And then you have trenacisation for transportation systems.
Did any anteater dinosaurs exist before that?
Ant eating dinosaurs exist today: https://learnbirdwatching.com/birds-that-eat-ants/
how many times things evolved into sharks?
ichtiozaur, dolphin/orca
anything else?
