Part 4: The dangling conversation In the previous article, we saw bacterial populations defend themselves collectively. Cyanobacteria formed protective flocs, while dying E. coli released enzymes that helped surviving cells withstand antibiotics. Throughout this series, communication has been the recurring theme: signals accumulate, populations respond, and collective behaviour emerges.

Male sperm whales produce exceptionally powerful slow clicks that may remain detectable across roughly 70 kilometres of deep ocean while maintaining remarkably precise intervals of five to ten seconds.

Longhorn crazy ants cooperatively transporting awkward loads through mazes reveal a striking scaling effect: larger teams solve geometrically difficult problems much more effectively than smaller ones, even when the physical burden per ant is held constant. Simple gravity-like simulations reproduce easy cases but fail on harder puzzles unless researchers add distributed, ant-like rules such as shifting force directions and responding to nearby openings. Unlike the simulations, the ants appear to apply broadly useful behavioural rules without retuning them for each maze.

A comparative study across arthropods finds that sperm cooperation is far more widespread and evolutionarily recurrent than previously assumed.

A game theory model examines how collective intelligence can arise when each individual observes only one part of a complex environment.

Observations from Mexico’s Gulf of California document orcas cooperating to dismantle large sharp-tail sunfish. One whale stabilised the prey while another accelerated into it, requiring precise positioning, timing and apparent coordination between participants. Researchers are considering several interpretations, including food processing, play, social bonding and adults demonstrating techniques to juveniles. Similar behaviours elsewhere show that orca groups can develop locally distinctive, socially transmitted methods for handling prey, although more observations are needed to establish how widespread this particular tactic is.

Groups of American cockroaches can continue occupying a shelter after environmental cues change, even though isolated individuals quickly move elsewhere.

Ultra-weak ‘biophotons’ might be used to diagnose disease, or could even represent a new signalling mechanism in cells.

In the previous article, we saw that bacteria may encounter several overlapping signals. Different messages can indicate neighbours, competitors, changing conditions or competing courses of action.

Long before a distant herd comes into view, an elephant likely already knows it is coming, thanks to silent messages sent through the ground.
