Revealing the workings of the human body on a scale never seen before, this is the most comprehensive account of how our unique and amazing bodies make us who we are. Breathtaking CGI takes viewers inside the body to show how different parts of our anatomy have evolved and why. Presented by Michael Mosley this programme takes us deep under our skin where we are dwarfed by even the smallest cell. Spectacular photography shows human behaviour in super slow motion, revealing elements of ourselves that we are completely unaware of. Presented by Michael Mosley.
