A few animals genuinely teach — they change what they do for a learner, at a cost to themselves, and the learner acquires a skill faster. Ants are among them.
Well supportedGood evidence backs this, though some details remain open.
Teaching, defined functionally as behaviour modified in the presence of a naive individual at a cost to the actor, which accelerates the naive individual’s learning, is documented in meerkats and in tandem-running ants. The definition makes no requirement about the teacher’s mental states.
- Who this applies to
- A small number of species meet the functional criteria. Most social learning in animals involves no teaching at all.Do not extend this beyond the taxa listed — the popular version over-reaches.
- Studied in
- Animalia
Why we rate it this way, and what the caveats are
Both key cases include a manipulation rather than observation alone: playback of pup calls in meerkats, and measurement of leader speed against follower contact in ants. Both show the demonstrator adjusting to the learner.
How far it can be extended
Only a handful of species have been tested against all three criteria, and most social learning proceeds without any modification of the demonstrator’s behaviour.
Caveats
- The functional definition deliberately excludes intention. An ant meeting it does not mean an ant intends to instruct.
- That definition is contested precisely because it admits cases many people would not call teaching.
- Most animal social learning — copying, being drawn to where others are feeding — involves no teaching whatever.
Still unanswered
- Whether any non-human teaches with an understanding that the other does not know something.
- Whether the functional definition should be tightened, and what would be lost if it were.

The leader’s pace is controlled by the follower’s antennal contact, the leader pays a fourfold time cost, and the follower subsequently finds the destination far faster.
