7 February

On 7 February in 850,000 BC, somebody walked across some mud in Happisburgh, Norfolk. The discovery of their footprints was reported exactly 852,014 years later, when scientists declared them to be the oldest footprints by early humans ever found outside of Africa. A guide for time travellers advised visitors not to wear trainers. (PROSE: Time Traveller's Diary)
