The fossil cast at 08:40 in the Bones episode is in fact KNM-ER 1813 rather than TM266-01-60-1. However the information stated about the fossil Sahelanthropus is correct.
• Your bones are as strong as granite in supporting weight. A block the size of a matchbox can support 9 tonnes.
• An adult has fewer bones than a baby. We start life with 350, but they fuse together as we grow and we end up with only 206.
• You use 200 muscles with each step, but only 12 of these are in the leg.
• The gluteus maximus is the largest and one of the strongest muscles in your body. It keeps the body erect and is the chief antigravity muscle that aids walking up stairs.
• People in our ancient past may have run faster than Usain Bolt. 20,000 year old fossilised human footprints in Australia show a male was accelerating barefoot at 23 mph in mud. Bolt can reach 26 mph, but only briefly and on a running track wearing high-tech shoes.
• The skin is your largest organ, with adults carrying about 4 kg and 2 square metres of it, covered by 4 million sweat glands producing about 500ml of sweat every day. Without skin you would literally evaporate.
• There are more living organisms on your skin than there are humans on the surface of the Earth. Every square inch of skin has about 32 million bacteria on it.
