The development of this technology is believed to have extended the waking portion of the human Circadian rhythm to its current 16 hours.
A 2016 paper by Heyes et al. suggests that the presence of manganese dioxide at Pech-de-l'Azé may mean that it was used in the production of this technology, whose competitive advantage is discussed in a 2009 popular book by Richard Wrangham ["RANG"-um]. The oldest known evidence of this technology was found in Wonderwerk [VAWN-dehr-vairk] Cave in South Africa. This technology was used in processing silcrete, making it easier to flake. The development of this technology is believed to have extended the waking portion of the human Circadian rhythm to its current 16 hours. It was used to (*) harden weapons like the Lehringen Spear. Percussive and friction methods of creating this technology are represented by bow drills and striking flint with metal. For 10 points, what is this technology used to cook food?
