Why Feet Are Weirder Than You Think

Compared with almost every other animal on Earth, our feet seem strangely specialised. They can't grip branches, they're full of arches and joints, and for some reason we're the only species that regularly puts shoes on them. Hannah and Michael explore how millions of years of evolution transformed ape like feet into powerful biological springboards, uncovering a surprising connection between human walking, pizza slices, and one of mathematics' most beautiful ideas. After the break, they ask why feet attract so much attention from WikiFeet ratings to one of the most common fetishes on Earth. ------------------- For more information about Cancer Research UK, their research, breakthroughs and how you can support them, visit https://www.cancerresearchuk.org/our-research/rest-is-science Cancer Research UK is a registered charity in England and Wales (1089464), Scotland (SC041666), the Isle of Man (1103) and Jersey (247).
