Concrete was poured into an giant underground ant megalopolis, which acts as a mold. After the concrete hardened, scientists carefully excavated it to reveal the structure of the ant's elaborate "city-state":
Everything looks like it has been designed by an architect, a single mind, but of course that isn't true. This colossal and complex city was created by the collective will of the colony, the super organism.
It's kind of grown-up reverse ant farm.
