What evolutionary pressure results in reef organisms producing complex, novel organic compounds?

Answer

Surviving chemical warfare among themselves and warding off predators

The highly competitive and densely populated nature of coral reef ecosystems forces resident organisms into constant chemical negotiation for survival. This intense evolutionary pressure, often described as chemical warfare among species competing for space or resources, drives the production of sophisticated, often novel, secondary metabolites. These organic compounds function as sophisticated defense mechanisms, serving both as deterrents against predation and as chemical weapons against competing sessile organisms. Pharmacologists find these molecules exceptionally interesting precisely because they are products of intense natural selection, suggesting inherent bioactivity applicable to human health challenges.
