Chemical Signalling and Colony Intelligence

Ants communicate primarily through chemical signals. Their language is built on pheromones, complex organic molecules produced by specialised glands, and a single ant can deposit dozens of different compounds to convey different information. Trail pheromones guide nest-mates to food. Alarm pheromones trigger escape or defence. Queen pheromones suppress worker reproduction. The precision of this chemical vocabulary is what allows colonies of millions to function as coordinated units.

The most studied case of ant communication is the alarm response. When a large animal or object approaches a colony, the vibrations and chemical disturbances trigger a specific sequence: a single detecting ant releases alarm pheromone, the pheromone binds to receptor neurons on the antennae of nearby ants, and those ants release the same pheromone in turn. The cascade can mobilise a colony of thousands within seconds. The signal is not undifferentiated. Different alarm pheromone components trigger different behaviours. Some drive escape, others drive attack, others recruit defenders to a specific point. An ant alarm call, in other words, is a structured message with a specific address and a specific content, not a single undifferentiated "danger" signal.

The structure of the ant alarm call has been refined in recent research. Entomologists have begun to show that the relevant unit of communication is not the single pheromone molecule but the combination. Cocktails of pheromone components, released in specific ratios, trigger specific and reproducible behaviours in the receiving ants. The call is closer to a code than a shout. It has parts, and the parts have meaning. Ants detecting an approaching threat are not just broadcasting alarm. They are specifying, through chemistry, what kind of threat, what response is appropriate, and which members of the colony should respond.

Islamic Context
حَتَّىٰ إِذَا أَتَوْا عَلَىٰ وَادِ النَّمْلِ قَالَتْ نَمْلَةٌ يَا أَيُّهَا النَّمْلُ ادْخُلُوا مَسَاكِنَكُمْ لَا يَحْطِمَنَّكُمْ سُلَيْمَانُ وَجُنُودُهُ وَهُمْ لَا يَشْعُرُونَ
Until, when they came upon the valley of the ants, an ant said, "O ants, enter your dwellings so that Solomon and his armies do not crush you while they do not perceive it."
— Quran 27:18

The ant's call in the verse has a structure. It opens with an address, yā ayyuhā al-naml (O ants), directed at the colony as a whole. The ant is not whispering to a neighbour. It is speaking to the entire community. Al-Qurtubi (d. 1273) noted that the address to the whole colony is what makes the verse distinctive. An individual ant is not merely retreating. It is organising the retreat of others, and the address is what does the organising.

Then come the directive and the named threat. Udkhulū masākinakum, enter your dwellings, and lā yaḥṫimannakum Sulaymānu wa-junūduhu, that Solomon and his armies do not crush you. The ant is naming both the action it wants the colony to take and the force that is approaching. The warning is not a general cry of danger. It is a specific instruction, paired with a specific reason. Al-Razi (d. 1210) noted that the ant's speech is precise rather than panicked. The ant is identifying the appropriate response and the specific threat, and conveying both. Mujahid, one of the earliest commentators, observed that the speech follows a recognisable order: address, instruction, justification. The call has parts, and the parts work together as a structured message.

Then comes the phrase that makes the verse's structure most pointed. Wa hum lā yashʾurūn, while they do not perceive it. Al-Razi noted that the phrase places the ant's perception and the humans' in opposition. The ant perceives the threat; the humans do not. The warning is being given precisely because the larger creatures are oblivious to the harm they are about to cause. The final component of the message is the asymmetry of awareness, and it is what gives the structured message its urgency. The ant is not warning for its own sake. It is warning because it knows something the humans do not.

The Connection

The Qur’an depicts an ant issuing a structured directive that matches what we now know about the precision of pheromone-based signaling. Science has revealed that ant communication is not panicked noise, but a sophisticated code of chemical ratios that specifies threat and target. The verse captures this exactly: it portrays an intelligent, audience-specific alert delivered with structural order. By highlighting the humans' lack of awareness, the text emphasizes that the ant's signal succeeds precisely because it conveys information the humans cannot perceive.
