Description

The introduction presents lichens as remarkable examples of cooperation and adaptation in nature. Although they are often overlooked, lichens represent complex living systems formed through relationships between fungi and photosynthetic partners such as algae or cyanobacteria. These partnerships allow lichens to survive in some of the most challenging environments on Earth.

The authors introduce lichens as organisms that challenge traditional ideas about what a single organism is. For much of scientific history, lichens were difficult to classify because they are not simply one organism but a community of interacting partners. Modern research has revealed their complexity and changed how scientists understand symbiosis and cooperation in nature
