Forget your smart phone, there was once a time when a lump of flint was the thing no one could live without.
500,000 years ago no hunter-gatherer was without their handy flint axe. Used for chopping, cutting, scraping and pounding it was the multi-tool of the day and essential for survival for our Neanderthal and earlier ancestors.
Fast forward to 6000 years ago and modern humans used flint tools to plough the first fields, whilst flint arrowheads became the first weapons of mass destruction.
