What is the worlds least intelligent?

Answer 1

It's difficult to definitively identify the "least intelligent" entity in the world, as intelligence can be measured in various ways and depends on context. Some might argue that simple organisms, like single-celled bacteria, exhibit minimal levels of intelligence due to their lack of complex nervous systems. However, even these organisms demonstrate adaptive behaviors essential for survival, challenging the notion of intelligence as a strictly human trait. Ultimately, intelligence is a multifaceted concept that varies widely across different species.
