Your article “Lichens unleashed” paints a picture of lichens as complex symbiotic communities with the ability to survive in space and thus potentially undertake interplanetary travel (27 December, p 38). Has anyone considered they could, in fact, be intelligent and highly developed aliens – albeit on a microscopic scale – living peacefully on Earth?
How like humans to spot and explore the potential to enslave them for our own benefit!
