Gene Up-Regulation in Response to Predator Kairomones in the Water Flea, Daphnia pulex

This detailed molecular analysis shows how environmental chemical signals trigger gene expression changes that produce defensive morphology in Daphnia. The research provides a textbook example of within-lifetime adaptation without genetic mutation - phenotypic plasticity in action.

The business parallel is clear: organizations don't need to fundamentally restructure (mutate) to respond to environmental change. They need gene regulation equivalents - culture and processes that permit different expressions based on detected conditions.
