Cave debris may be the oldest example of people who eat starch

Science

Small fires in a cave in South Africa caused what the researchers considered to be the oldest examples of key decisions in daily food from parents. No, there is no dessert. Think of roasted starch plants.

The Sgoreli system remains classified as dating back around 120,000 years, about 65,000 years ago on the cave river, archaeologist Cynthia Labelle said from the University of Cambridge in England and her colleagues. Organic fragments containing starch granules, however, cannot be associated with plant species known to contain starch.

Based on locally available plants, people can from Stone Age bulbs and roots in caves have been prepared, scientists say. Compared to raw tapioca flour mills their cooked counterparts offer people a very effective source of glucose and thus for energy. Human fossils were previously found in coastal caves at the southern tip of Africa, also dating from earlier around 120,000 years ago.

Old cornmeal at River Cave Classification supports the possibility that Homo sapiens genetic improvement was developed to help long before people started starch plants in Africa growing around 10,000 years to absorb poorly degradable starch. Scientists have found that more copies of the gene for digestion today have Stone Age populations such as Neanderthals and Denis.

Old people in South Africa may mix boiled roots and food tubers, shellfish, fish and games (SN: 8/13/11, p. 22), said Larbey’s team. Roots and tubers will be available throughout the year. While little is known about the origin of cooking, at least 300,000 years ago was built in the African campfire (SN Online: 2/20/14).
