Why Fungi?

Prehistoric ancestors of modern fungi called Prototaxites emerged more than 400 million years ago, during the Silurian–Devonian transition, when Earth’s terrestrial ecosystems were still sparse, strange, and dominated by microbial crusts, primitive plants, and early fungi-like life.

Fungi are among Earth’s ancient terrestrial pioneers. Long before modern forests or animals transformed the continents, fungi helped shape early land ecosystems. These organisms faced a harsher planet: stronger ultraviolet stress, limited nutrients, desiccation, and unstable surface conditions. Over deep evolutionary time, fungi developed remarkable survival strategies, including robust DNA repair systems, resistant spores, protective pigments, metabolic flexibility, and the ability to recycle complex matter. The emerging field of Astromycology asks how these ancient adaptations can inform the biological future of space exploration.
