What happened
By about 2.6 million years ago, early humans were deliberately making the first stone tools. The Smithsonian describes this earliest toolkit, known as the Oldowan, as the most basic stone implements: hammerstones, stone cores, and the sharp flakes struck off them, which could cut and scrape in ways bare hands could not. Toolmaking then spans the whole 2.6 million years since, a record that runs unbroken from a chipped stone flake all the way to the device you are reading this on.
Why it matters
Tools let our ancestors act on the world instead of only adapting to it: butchering meat, working wood, and eventually reshaping their whole environment. Every technology on every later timeline the site holds, from the printing press to the microchip, is a distant descendant of this first sharp flake.
How we know
The Smithsonian Human Origins Program describes stone toolmaking spanning the past 2.6 million years, beginning with the Oldowan toolkit of hammerstones, cores, and sharp flakes.
