Weird Biology

The brand-new, hilarious book from best-selling, record-breaking author Adam Kay. The olden days were pretty fun if you liked wearing chainmail or chopping people's heads off, but there was one tiny little problem back then...doctors didn't have the slightest clue about how our bodies worked. It's time to find out why Ancient Egyptians thought the brain was just a useless load of old stuffing that might as well be chucked in the bin, why teachers forced their pupils to smoke cigarettes, why hairdressers would cut off their customers' legs and why people used to get paid for farting.

In recent years, scientists have hypothesized life-forms that can only be called "weird": organisms that live off acid rather than water, microbes that thrive at temperatures and pressure levels so extreme that their cellular structures should break down, perhaps even organisms that reproduce without DNA. Some of these strange life-forms, unrelated to all life we know, might be nearby: on rock surfaces in the American southwest, hydrothermal vents on the ocean floor, or even in our own bodies. Some, stranger still, might live in Martian permafrost, swim in the dark oceans of Jupiter's moons, or survive in the exotic ices on comets.
