Why do ants work in colonies?
Show answer & explanation
Answer: Division of labor increases success
Ants enjoy social interaction — Wrong. Ants don't have emotions like enjoyment. Colony structure evolved because division of labor dramatically increases survival success.
Learning from older ants — Wrong. Ants don't learn socially—behaviors are largely instinctive (genetic). Colony succeeds through division of labor and chemical communication.
Division of labor increases success ✓ — Correct! Eusocial superorganism! Ant colonies show division of labor: (1) Queen—reproduction only. (2) Workers—foraging, nest building, brood care. (3) Soldiers—defense. (4) Some species: farmers (grow fungus), herders (tend aphids). Chemical communication (pheromones) coordinates colony. Collective intelligence—colony acts like single organism. Leafcutter colonies: 8 million individuals! Individuals sacrifice for colony (kin selection—share genes with queen's offspring). Evolutionary advantage: specialization outcompetes generalists!
