Simplexidels

Simplexidels are a hypothetical group of organisms proposed in speculative fiction, primarily known for their unique biological structure. They are characterized by a single, undifferentiated cell that performs all life functions. This means that instead of having specialized tissues and organs like most multicellular life, a simplexidel's entire existence is contained within one cellular unit. This singular cell is capable of reproduction, metabolism, and response to stimuli. Their simplicity is their defining trait, allowing them to potentially thrive in environments where complex life might struggle due to resource limitations or extreme conditions. The concept of simplexidels often explores the boundaries of what constitutes life and the diverse forms it might take beyond Earth. While not based on current scientific discovery, they serve as a thought experiment in astrobiology and evolutionary biology, prompting consideration of simpler life forms as potential extraterrestrial inhabitants. Their existence remains purely theoretical.
