> ants are smarter than they look.

Many moons ago I had a big pot of rhubarb in my back yard¹ and was initially irritated by the appearance of ants and aphids, until I took a moment to watch them and realise that the ants were bringing in the aphids and tending to them. The buggers were farming. The ants can't digest the leaves of the rhubarb, but the aphids can and excrete a sugary by-product that the ants “milk” from them. It is a fascinating bit of nature to read into. They even defend the aphids from predators and so forth, so it isn't a bad life for them either.

[1] Not a euphemism for a lovely garden in that case, it was literally about a square yard of concrete behind the mid-terrace I was renting.

> But in all seriousness, ants are smarter than they look.

I'd argue the opposite, ants are dumber than they look. You look at a random ant stack in the forest and it looks like they're smart, but that's only when they're "controlled" by the collective, individual ants themselves are pretty dumb in the end, but it's hard to see as typically we always see them around/in their stacks in nature.

As a collective, yes. If you look at individuals, they often go in circles and act really dumb. But for the colony it still works out, bigger brains would cost too much energy I suppose and simple algorithms work. (I often watched real ants while and my head translated their behavior to simple algorithms)

Someone else who has read Godel, Escher, Bach by Hofstadter?
