A new fleet of autonomous robots is now making one of the world's oldest foods

In the beginning, archaeologists believe, the first breads were created using some of the most rudimentary technologies in human history: fire and stone. In the region that now encompasses Jordan, one of the world's most ancient examples -- a flatbread vaguely resembling pita and made from wild cereal grains and water -- was cooked in large fireplaces using flat basalt stones, according to Reuters. The taste is "gritty and salty," Amaia Arranz-Otaegui, a University of Copenhagen postdoctoral researcher in archaeobotany, told the news service. "But it is a bit sweet, as well." More than 10,000 years later, bread has clearly evolved but, perhaps, not as dramatically as the technology being used to bake it.
