Most of these languish in obscurity – many have never even been named – but some of the relatively few species that have been studied exhibit remarkable abilities. Many of these are physical: some micro-organisms are amazingly strong; others can hibernate for hundreds of thousands of years or thrive in environments so extreme that they would kill off most other life forms in a flash.

But many bacteria and protists also exhibit behaviour that looks remarkably intelligent. This behaviour isn't the result of conscious thought – the sort you find in humans and other complex animals – because single-celled organisms don't have nervous systems, let alone brains.
