蚂蚁如何建造如此复杂的地下城市？

Ant colonies dig intricate tunnel networks using their strong mandibles and coordinated teamwork.
Each ant follows simple rules based on pheromone trails and soil texture, not a central plan.
Tunnels stay stable because ants avoid sharp angles and reinforce walls with saliva and soil.
Ventilation shafts allow fresh air to flow deep underground without human tools.
Nurse ants carry eggs and larvae to warmer or cooler chambers depending on developmental needs.
Some species even farm fungi or herd aphids, turning parts of their nests into living farms.
The queen stays protected in a central chamber while workers handle construction and repairs.
Ants adjust tunnel size and layout as the colony grows or seasons change.
Researchers study ant digging to improve robot algorithms for underground exploration.
Their cities can last decades and house millions—built entirely without blueprints or supervisors.
