What our ancestors ate? Discovered the remnants of food left by the age of 65 thousand years Source:

What do you think ate human ancestors thousands of years ago? Today we know the exact answer to this question, as scientists have discovered the charred remains of different plant foods in Northern Australia. The age of the finds ranges from 65 000 to 53 000 years. Food residues preserved in the ruins of the ancient kitchen fire in Magebane — the shelter of Sandstone, which is considered the oldest dwelling place in Australia. According to a study published in the journal , the researchers, with the help of local aborigines, were able to identify 10 different plant products, analyzing the preserved charcoal.

Happy accident

After Analyzing the preserved charcoal, the researchers came to the conclusion that the natives were preparing a variety of fruits, nuts, palm stems, roots and tubers. As said study co-author Anna Florin from the University of Queensland (Australia) and food remains were preserved by chance. These specific food waste had been touched by the fires because of cooking and turned into charcoal. They represent the earliest evidence of the use of plant foods outside of Africa and the Middle East.

In the study, scientists were able to extract small pieces of coal from the earliest aboriginal settlements in Magebane. Identification was performed by comparison of ancient remains with modern reference materials under the microscope of very high power. The study's authors write that the results obtained have shown that the earliest known human population in Australia, a number of plant products, including those that required treatment. To make these products edible, the natives complements the culinary process technology grinding stone.

it looks like the Sandstone Magebane

Anyway, today scientists do not doubt that the first Australians had an extensive Botanical knowledge. This knowledge later allowed them to adapt and thrive in a new, unfamiliar environment. Ancestors were able to guarantee access to carbohydrates, fats and even proteins, applying the knowledge and developed technological innovation and labor for collection and processing of Australian plant products. Researchers believe that recent discoveries predate existing evidence of such practices in Shule — a continent that once consisted of Australia, New Guinea, Tasmania and the Indonesian island of Seram.

Some experts suggest that early movements through island Southeast Asia in Sahul facilitated access to high-calorie foods. The results indicate that the breadth of the power was the basis of the success of the early modern population in the region, and labor costs for processing plants ensured reliable access to nutrients in the new environment. Ancient herbal products are just one of several significant discoveries that were made in Magebane. For example, there was discovered evidence of the earliest technology of the grinding stone outside Africa and the first was the use of reflecting pigments in any part of the world.
