ted 2003 – The emergent genius of ant colonies

i like to think about how org’s work.. how the simple parts interact to create the behavior of the whole org

systems like ants: web, brain, cells, …

about 10 000 species of ants.. live in colonies .. 1 or 2 queens.. most walking around sterile female workers.. no central control…

how behavior changes as colonies get older…

3 min – every year on same day.. each colony sends out virgin unmated queen. and male. and they mate.. after that males die.. the newly mated queen … fly off.. drop wings.. live for 15-20 yrs continuing to lay eggs from that original mating..

change in years.. 10-12 000 ants at age 5… stays that age for 15 ish years till queen dies.. cycles again..

colony size changes as colony age..  what i think about – task allocation.. how does it change what it’s doing.. ie: adjusting as conditions change.. w/nobody telling anybody what to do .. how do they adjust…

4 categories: foraging/patrollers/nest maintenance workers/midden workers (put territorial chemical in garbage) – only about 25% of colony.. and oldest ants

ants you see walking around don’t do much eating

curiously looks as though about 1/2 ants in colony are doing nothing.. bible.. look to the ant oh sluggard… if something happened might all come out if needed.. but rarely come out… what function to a reserve of ants.. doing nothing..

never nothing going on…

9 min – don’t see very well – mostly work by smell… even if queen did have intelligence to send chemical messages to tell others what to do.. no way could make it in time to see shifts.. so .. she’s not directing behavior of colony

what’s relationship between ants doing diff tasks.. i was thinking .. each ant dedicated to one task from birth..  so i experimented.. found… diff tasks are interdependent and ants switch tasks.. they go off what’s needed to be done…

13 min – older colonies.. more stable… not any older.. not due to experience of older/wiser ants… (because only live a year)… only change is colony size…

so what kinds of decision or rules.. since no ant can access global situation.. that would change as colony gets larger… what i’ve found.. is antennae interaction.. it’s the rate at which it meets other ants.. that tells them what to do..

how can an ant tell i’m a forager… and if i start to meet higher number of nest maintenance.. i switch.. this layer of grease on outside of ant… longer they stay outside… so task specific order.. used in brief antennal contacts…

17 min – this system is messy/variable/noisy.. in particular.. 1\ experience of each ant can’t be very predictable.. rate at which it comes back depends on what happens to it.. 2\ ants ability to access this pattern must be very crude.. because ant can’t do counting..

it’s not that this haphazard pattern of interactions produces a factory with precisions.. in fact .. if watch them.. end up wanting to help them… it’s not that perfection arises.. but works pretty well.. been around a long time.. something they’re doing is clearly successful enough…

you’d expect interactions to be closely connected to colony size… when ant in large/colony can’t use same rule.. as colony develops produces diff behavior..


ted 2014 – What ants teach us about the brain, cancer and the Internet

i study ants.. using interactions diff in diff environments.. could learn from them about .. brains, data networks, cancer… they all have no central control…

in ant colony.. no one in charge.. rather.. very simple interactions.. ants use smell..

mechanism simple enough ness

doesn’t matter which ant it meets.. and no major complicated signal/message.. all that matters to the ant is the rate at which it meets other ants..  this constantly shifting network that produces the behavior of the colony…

ant network.png

our brain works in the same way .. but what’s great about ants is you can see the whole network as it happens

using interactions diff to meet diff challenges.. ie: operation costs, find/collect resources…

the system works to stay stopped unless something is happening

above video – on doing nothing ness

why some colonies forage less than others.. thinking of ants as neurons.. whether there might be small diff’s and how many interactions each ant needs to go out and forage…

the brain – maybe some individuals/conditions that electrical neurons need more stimulus to fire..

reproductive success.. colony lives about 28 years , ie: colony 154 is a great grandmother.. offspring colonies resemble parent colonies in their decisions.. even though ants never meet.. so can’t be learning from parent colony… so look at genetics..

colonies that conserve water.. ie: stay in when really hot outside.. do better… i thought colony 154 was a loser because they stayed in and did nothing.. but not so..

finding out what’s actually working best

internet uses algo to generate flow of data… we call this analogy.. the anternet… data doesn’t leave unless signal that there’s enough bandwidth to flow… ants using algo so similar to one we recently invented… and ants have had 130 mill years to evolve.. and thinking other colonies will have great insight we haven’t thought of yet

where ants abundant and diverse…  where it’s go.. unless something negative happens..

they use their interactions to measure density

cancer – ants never poison own colonies… many diff kinds of cancer… some will spread… where must be getting resources they need… if resources are clustered likely to use interactions for recruitment.. so if we figure out how.. like ants.. we could set traps…

Gordon studies ant colony behavior and ecology, with a particular focus on red harvester ants. She focuses on the developing behavior of colonies, even as individual ants change functions within their own lifetimes.

Gordon’s fieldwork includes a long-term study of ant colonies in Arizona. She is the author of numerous articles and papers as well as the book Ants at Work for the general public, and she was profiled in the New York Times Magazinein 1999.

fantastic quote, re-watching it myself now :) Reminds me of a quote I pulled from this aeon article:…

(dec 2016) – The queen does not rule… The ant colony has often served as a metaphor for human order and hierarchy. But real ant society is radical to its core

Historically, many have found the idea of division of labour a compelling and powerful model. .. But it’s not natural. A vision of human society ordered and improved by division of labour has permeated and distorted our understanding of nature.

science of people ness

human nature

The implication was that the workers in an ant colony, all sisters or half-sisters, are divided into naturally fixed groups, and genetically programmed to perform a particular task. .. each ant’s role is unalterable destiny,

we know now that ants do not perform as specialised factory workers. Instead ants switch tasks……Yet in an ant colony, no one is in charge or tells another what to do.

Like many natural systems without central control, ant societies are in fact organised not by division of labour but by a distributed process, in which an ant’s social role is a response to interactions with other ants.

to respond to the changing world.

This social coordination occurs without any individual ant making any assessment of what needs to be done.

verifiability.. supposed to .. ness

rather.. indigenous us

However appealing it might be to imagine ant colonies organised by division of labour, the evidence tells us they are not.

the collective process of task allocation in ant colonies is based on networks of simple interactions.

Each encounter, in the form of a brief antennal contact, has no meaning to the ant, but in the aggregate, the rate of encounters determines how many ants are currently foraging.

simple mech to facil whimsy

The system that ant colonies use to organise their work is a distributed process.

Primarily, in a distributed process, there is never central control, while in division of labour there might be.

For division of labour, specialisation can lead to better work. By contrast, in a distributed process, the fact that individuals are interchangeable makes the whole system more robust and more resilient.

the term ‘distributed process’ originated in computer science…. no single unit,…knows what all the others are doing and tells them what to do. … Distributed processes often operate in parallel rather than in series. …In a parallel process, different steps can be done at the same time.

Ants can show how distributed processes might allow us to adjust to a changing environment

as temp placebo.. getting us back to listening..

although certain large regions of the brain seem to be involved in particular tasks, at the level of neurons it looks like division of labour is not the rule.

We say that disease, intelligence, psychosis, athletic ability and so on are ‘genetic’, as if inside a person’s cells there were little switches labelled ‘cancer’ or ‘paranoia’ or ‘endurance’. In fact stress, sunlight, exercise and similar influences can change which genes are turned off and on. Biologists are learning that what genes do depends as much on what is happening outside as well as inside the cell.

human nature

To envisage how an ant’s task of the moment arises from a pulsing network of brief, meaningless interactions might compel us instead to ponder what really accounts for why each of us has a particular job.

a story about people grokking what matters

The alternative, that a person is a shifting flux of impressions and feelings, lacking a defined core, is difficult to grasp.

The most fundamental appeal to the idea of division of labour is, perhaps, that it provides a reassuring sense of control.

reassuring..? or deadening..?

Reality is less soothing but much more interesting. A distributed process can be messy and not fully predictable, yet can provide greater resilience and robustness.

Division of labour is a human innovation, drawing on our ability to learn and improve by practice, and to trade goods and services. The growing recognition that natural processes work differently from our symphonies and armies will allow us to see the natural world more clearly.
