Signals Across Species: Coordination, Likes, and Pheromones — 3 Eusocial Insects and Pheromone Coordination

Humans coordinate via symbolic traces, herd mammals via observable behaviour, and eusocial insects — ants, bees, termites — achieve collective alignment through chemical signalling. Pheromones provide a striking example of distributed, non-symbolic coordination, highlighting how ecological pressure operates across different semiotic/functional systems.

1. Chemical Signals as Minimal Moves

In insect colonies, coordination relies on pheromones:

• Trail pheromones: guide foragers to food sources.

• Alarm pheromones: signal threat and mobilise defence.

• Task allocation pheromones: regulate division of labour.

Each pheromone release acts as a minimal signalling move:

• It does not represent or evaluate another’s mental state.

• It is relational: it shapes the probability of neighbouring insects’ behaviour.

• Iteration occurs as multiple individuals deposit, sense, and follow pheromone gradients, creating emergent colony-level alignment.

2. Distributed Micro-Interaction Ecology

The ecology of pheromone signalling is highly parallel and cumulative:

1. An individual detects a stimulus (food, threat, or task need).

2. It emits pheromones, altering the chemical gradient in the environment.

3. Nearby individuals sense the gradient and adjust behaviour.

4. The process repeats, producing emergent alignment at the colony level.

Like human social media likes, these are iterated minimal moves, but they differ fundamentally:

• Signals are chemical, not symbolic.

• Feedback loops operate physically, not representationally.

• Coordination is constrained by sensory thresholds and chemical decay.

3. Ecological Pressure and Probability Bias

Pheromone-based signalling produces probabilistic bias similar to herds:

• High concentration → higher probability of following the trail or engaging in the task.

• Low concentration → lower probability, reducing the likelihood of action.

• Iterated deposition and sensing create self-reinforcing patterns, e.g., dominant foraging paths.

However:

• There is no metaphenomenal meaning: insects are not aware of alignment as “meaning about meaning.”

• Structural drift is ecological and behavioural, not symbolic: colony coordination adapts within constraints but does not create new semiotic potential.

4. Comparison with Humans and Herd Mammals

Feature	Humans: Likes	Herd Mammals	Eusocial Insects
Signal type	symbolic, metaphenomenal	behavioural/postural	chemical/pheromone
Iterability	high, low-cost, digital	moderate, local	high, distributed, cumulative
Visibility	public, global	local neighbours	local via chemical gradient
Coupling to value	attention, prestige	survival	colony-level functional efficiency
Metaphenomenal meaning	present	absent	absent
Ecological pressure	biases semiotic potential	biases behaviour probabilities	biases colony action probabilities
Structural transformation	possible (semiotic drift)	unlikely	evolutionary timescale only

Key insight: insect coordination exemplifies distributed minimal moves producing emergent alignment, analogous in mechanism to likes and herd signals, but without symbolic mediation or metaphenomenal meaning. The functional outcome is entirely constrained by ecology and biology.

5. Takeaways for Cross-Species Analysis

• Pheromone signalling demonstrates highly parallel, cumulative coordination with strong ecological feedback.

• Probabilistic bias drives emergent colony-level patterns, but no symbolic or metaphenomenal layer exists.

• Humans are unique in coupling symbolic minimal moves with visible aggregation and social value, producing rapid, short-term systemic drift in semiotic potential.

• Herd mammals and insects achieve functional coordination through iterated minimal acts, but constrained by local interaction and survival imperatives.
