But despite the Secret Service–like behavior, and the regal nomenclature, there's nothing hierarchical about the way an ant colony does its thinking. "Although queen is a term that reminds us of human political systems," Gordon explains, "the queen is not an authority figure. She lays eggs and is fed and cared for by the workers. She does not decide which worker does what. In a harvester ant colony, many feet of intricate tunnels and chambers and thousands of ants separate the queen, surrounded by interior workers, from the ants working outside the nest and using only the chambers near the surface. It would be physically impossible for the queen to direct every worker's decision about which task to perform and when." The harvester ants that carry the queen off to her escape hatch do so not because they've been ordered to by their leader; they do it because the queen ant is responsible for giving birth to all the members of the colony, and so it's in the colony's best interest-and the colony's gene pool-to keep the queen safe. Their genes instruct them to protect their mother, the same way their genes instruct them to forage for food. In other words, the matriarch doesn't train her servants to protect her, evolution does. Popular culture trades in Stalinist ant stereotypes-witness the authoritarian colony regime in the animated film Antz-but in fact, colonies are the exact opposite of command economies. While they are capable of remarkably coordinated feats of task allocation, there are no Five-Year Plans in the ant kingdom. The colonies that Gordon studies display some of nature's most mesmerizing decentralized behavior: intelligence and personality and learning that emerges from the bottom up.
