[…] What is surprising is how poorly we still understand global ant societies: there is a science-fiction epic going on under our feet, an alien geopolitics being negotiated by the 20 quadrillion ants living on Earth today. It might seem like a familiar story, but the more time I spend with it, the less familiar it seems, and the more I want to resist relying on human analogies. Its characters are strange; its scales hard to conceive. Can we tell the story of global ant societies without simply retelling our own story?
[…] Recognition looks very different for humans and insects. Human society relies on networks of reciprocity and reputation, underpinned by language and culture. Social insects – ants, wasps, bees and termites – rely on chemical badges of identity. In ants, this badge is a blend of waxy compounds that coat the body, keeping the exoskeleton watertight and clean. The chemicals in this waxy blend, and their relative strengths, are genetically determined and variable. This means that a newborn ant can quickly learn to distinguish between nest mates and outsiders as it becomes sensitive to its colony’s unique scent. Insects carrying the right scent are fed, groomed and defended; those with the wrong one are rejected or fought.
[…] It is remarkable how irresistible the language of human warfare and empire can be when trying to describe the global history of ant expansion. Most observers – scientists, journalists, others – seem not to have tried. Human efforts to control ants are regularly described as a war, as is competition between invaders and native ants, and it is easy to see why comparisons are made between the spread of unicolonial ant societies and human colonialism. People have been drawing links between insect and human societies for millennia. But what people see says more about them than about insects.
This means that a newborn ant can quickly learn to distinguish between nest mates and outsiders as it becomes sensitive to its colony’s unique scent. Insects carrying the right scent are fed, groomed and defended; those with the wrong one are rejected or fought.
For the entomologist Neil Tsutsui, who studies unicolonial ants at the University of California, Berkeley, insects are like Rorschach tests. Some people see his research as evidence that we should all get along, while others see the case for racial purity.
Does anyone know of any articles/papers about using ants in bioengineering?
Interesting question. My background is in computer science so I’ll definitely be interested to hear of any more “biological” research related to ants. In CS there’s a class of stochastic optimization algorithms that are inspired by how anthills solve problems and have analogue to eg. pheromones. See eg. this Scholarpedia page for more information. Also here is a paper with the funny title “Do Ant Colonies Obey the Talmud?” about computation and ant colonies – it uses a Talmudic example to show that ant colonies at least as defined in the simplified model are capable of solving optimization problems
