In June 2019 Science News reported that discoveries in East Africa of what may be the oldest expertly sharpened stone implements suggest early members of the human genus Homo invented advanced flaking techniques about 2.6 million years ago in what is now Ethiopia.
Oldowan tools are a foundation story for human technology, so new claims that early knappers already worked with precision still matter for Horn readers who follow archaeology from the Afar and related sites.
Kept as science and archaeology archive, the report dates another chapter in the debate over how early Ethiopian stone-tool makers shaped the human deep past.
