New discoveries made at the Klasies River Cave in South Africa’s southern Cape, where charred food remains from hearths were found, provide the first archaeological evidence that anatomically modern humans were roasting and eating plant starches, such as those from tubers and rhizomes, as early as 120,000 years ago.

Discovery reveals plant-based menu of prehistoric man

THE HEBREW UNIVERSITY OF JERUSALEM—A tiny grape pip (scale 1mm), left on the ground some 780,000 years ago, is one of more than 9,000 remains of edible plants discovered in an old Stone Age site in Israel on the shoreline of Lake Hula in the northern Jordan valley, dating back to the Acheulian culture from 1.75-0.25 million years ago. The floral collection provides rich testimony of the plant-based diet of our prehistoric ancestors.

While around the world remains of Paleolithic plants are scarce, this unique macro-botanical assemblage has allowed researchers from the Hebrew University of Jerusalem and Bar Ilan University to study the vegetal diet of humans from early-mid-Pleistocene, which is central to understanding the evolution, adaptation and exploitation of the environment by hominins.
The findings were recovered during archeological excavations at the waterlogged site of Gesher Benot Ya’aqov, where the earliest evidence of human-controlled fire in western Asia was discovered in recent years.
Prof. Naama Goren-Inbar of the Institute of Archeology at the Hebrew University of Jerusalem, who conducted the excavations with colleagues, have long studied findings of hominid occupations in the Levantine Corridor, through which several hominin waves dispersed out of Africa.
In a research paper that will be published in the Proceedings of the National Academy of Sciences (PNAS) on December 5, titled “The plant component of an Acheulian diet: a case study from Gesher Benot Ya’aqov, Israel”, Prof. Goren-Inbar reveals the discovery of the ancient macrobotanical remains, which for the first time indicate to the rich variety of plant assortments and subsistence opportunities that were available to the early humans on the transition from an African-based to a Eurasian diet.
“In recent years we were met with a golden opportunity to reveal numerous remains of fruits, nuts and seeds from trees, shrubs and the lake, alongside the remains of animals and man-made stone tools in one locality,” Prof. Goren-Inbar said.
Of the remains found on site, Prof. Goren-Inbar and Dr. Yoel Melamed of the Faculty of Life Sciences at Bar Ilan University have identified 55 species of edible plants, including seeds, fruits, nuts, leaves, stems, roots and tubers.

The findings, many of them minor in size, have been preserved for hundreds of thousands of years thanks to the damp conditions in the vicinity of the site, said Dr. Melamed. The basalts under and in the site were dated by Ar/Ar and the dates were further confirmed by results of paleomagnetic analyses.
“This region is known for the wealth of plants, but what surprised us were the sources of plant food coming from the lake. We found more than 10 species that existed here in prehistoric times but no longer today, such as two types of water nuts, from which seven were edible,” explained Dr. Melamed.

The site was submerged under the Jordan River and the Hula Lake in conditions of humidity and lack of oxygen, aided by the fast covering of layers of sediments, in which archaeologists also found stone tools and animal fossils.
Gesher Benot Ya’aqov is also the place where Prof. Goren-Inbar found the earliest evidence of the use of fire in Eurasia (LINK). “The use of fire is very important because a lot of the plants are toxic or inedible. Using fire, like roasting nuts and roots for example, allows the use of various parts of the plant and increases the diversity of the plant component of the Acheulian diet, alongside aquatic and terrestrial fauna,” said Prof. Goren-Inbar.
The use of fire and the availability of a diverse range of flora highlight the ability of prehistoric man to adjust to a new environment, to exploit the environment for his own benefit and to colonize beyond Africa.

Live science

This harvest came 3,000 years too late.
Hundreds of blackened potatoes were pulled out of the ground at a prehistoric garden in British Columbia, Canada.
Dating back to 3,800 years before the present, the garden was once underwater, in an ecologically rich wetland. And it shows signs of sophisticated engineering techniques used to control the flow of water to more efficiently grow wild wapato tubers, also known as Indian potatoes. 

Archaeologists led by Tanja Hoffmann of the Katzie Development Limited Partnership and Simon Fraser University in British Columbia uncovered the garden during roadwork on Katzie First Nation territory just east of Vancouver, near the Fraser River.

The site had been waterlogged for centuries, resulting in good preservation of plants and other organic materials like wooden tools that would have normally disintegrated over time.

In all, the researchers counted 3,767 whole and fragmented wapato plants (Sagittaria latifolia). Today, these plants are found in wetlands across southern Canada and the United States. Though they were not domesticated, the chestnut-sized roots had long been important to indigenous people, and they are mentioned in some of the first ethnographic accounts of the Pacific Northwest. Explorers Meriwether Lewis and William Clark, for example, were offered wapato roots at a native village near present-day Portland, Oregon. Clark wrote in his diary that the plant resembled a “small Irish potato,” and after being roasted, had “an agreeable taste and answers very well in place of bread.”

The ancient tubers that were found in British Columbia had turned dark brown to black in color, and some still had their starchy insides preserved. The garden had been covered in tightly packed, uniformly sized rocks, leading the researchers to conclude that this was a man-made deposit. Wapato plants can grow far underground, but an artificial rock “pavement” would have controlled how deep the roots could penetrate. This would have allowed the harvesters to more easily find the tubers and pull them out of the muck, Hoffmann and her colleagues wrote in their study, published Dec. 21 in the journal Science Advances.

Besides this waterlogged garden, the archaeological site also had a dry area where people would have lived. The researchers also found about 150 wooden tools that would have been used to dig out the plants.

Radiocarbon dates from the burnt wood found at the site suggest it dates back to 3,800 years ago and was abandoned 3,200 years ago.

The site could represent the first direct evidence of wetland plant cultivation in the prehistoric Pacific Northwest, according to the report on this discovery.
