Biological Parallel
Fitness landscapes explain why optimization for one role guarantees nothing about the next. Cheetahs perfected for speed lose kills to combat-optimized competitors. Irish elk antlers drove reproductive success until habitat loss made them a metabolic death sentence. Giant pandas specialized on bamboo so narrowly that any habitat disruption creates existential crisis. Darwin's finches demonstrate the landscape shifting in real time — beak depth optimized for one seed distribution becomes a liability when conditions change.
