Scientific research increasingly shows that biological novelty is created by horizontal fusions between species. Our very cells are the product of an ancient bacterial merger. Whole landscapes and species are only possible because beings decided to co-become. In a culture that enshrines the individual, what health and resilience have we denied ourselves? Is it possible that there are better futures visible only from the vantage point of symbiotic collaboration? More simply, with every spore-threaded breath we are but built and rebuilt from our physical environment. When we choose to inhale otherness, we acknowledge the intelligence of our bodies is not solitary, it is relational. Our bodies are open systems, waiting for the right questioning touch. In an age of ecological crisis and unforeseen change, future worlds may only become thinkable when we think between belief systems and between bodies.
