Early humans used grinding tools that were potentially part of a process for making simple breads, discoveries in what is now the north of Saudi Arabia show.
The findings, published in the journal Plos One, provide a deeper understanding of the subsistence strategies and cultural practices of Neolithic populations in a region where the preservation of organic matter is limited because of the aridity.
Northern Arabia was once considerably greener and wetter, making it much more conducive for early human populations to find water and game.
However, due to the present dry climate, little organic matter has been preserved, posing challenges to the reconstruction of Neolithic lifestyles.
Researchers adjusted dating methods to consider changes in the atmosphere's carbon levels over time.
Maria Guagnin, one of the lead authors from the Max Planck Institute of Geoanthropology, told The National one of the sites had a build-up of several layers "and the layers with the grinding tools were dated to about 7,000 to 8,000 years ago".
"The second site is also Neolithic with most of the fireplaces dated to between [about] 5300 and 4800 BC," she said.
Through the use of high-powered microscopes, researchers from the Max Planck Institute, the National Research Council of Italy, the Institute of Heritage Science and University College London conducted a use-wear analysis of grinding tools discovered at Jebel Oraf in the Nafud desert.
These grinding tools are believed to have been used to process bone, pigment and plant matter.
Moreover, these tools were repurposed over their lifespan until they were ultimately broken and placed on hearths.
By comparing the wear patterns on these ancient tools with modern experimental ones, scientists determined that different grinding activities leave distinct traces on the tool's surface.
"The findings allow us for the first time to get an understanding of the organic materials that were processed at the site, which have not survived because of the extreme aridity in the region today," Ms Guagnin told The National.
"The grinding stones are really striking. We now know that these highly mobile herders carried heavy grindstones – up to 3kg – with them because they used these tools for a range of different materials, which were all important for their daily life."
The Neolithic tools exhibited signs of being used to process meat and bones, suggesting that bones might have been crushed to gain access to the marrow.
While there is no evidence of domesticated grains in this period in northern Arabia, the study’s authors believe wild plants were ground and perhaps even baked into simple breads.
“The hearths where we found the grinding tools were extremely short-lived, indicating that Neolithic people might have been highly mobile,” Ms Guagnin said.
“Breads would have been a portable and ideal food for such populations.”
In addition, the tools provided evidence of pigment processing, which may have been associated with art.
The study suggests that pigments were processed on a larger scale than previously thought, suggesting the existence of more Neolithic rock art than the few surviving panels indicate.
“The Neolithic residents of Jebel Oraf clearly valued grinding tools,” said Giulio Lucarini, the study’s other lead author from the National Research Council of Italy.
“Many were extensively used, some to the extent that they had holes, indicating they might have been transported. This emphasises that these heavy grinding tools played a vital role in their daily routines.”
"The grinding tools we analysed were all made of sandstone, which is locally available," Ms Guagnin told The National.
"However, sandstone is not available directly at the site – they seem to have had grindstone workshops some kilometres away and then brought the tools to a camp site next to an ancient lake."
The methodology used in this research is a rarity for archaeological finds from the Arabian Peninsula.
However, it offers invaluable insights into the production, use and re-use of these ancient tools, shedding light on the daily lives, economy and art of the people who used them.
Researchers collaborated closely with the Saudi Ministry of Culture during the study, with further partnerships involving King Saud University and institutions from the UK, Ireland and Australia.

THREE POSSIBLE REPLACEMENTS
Khalfan Mubarak
The Al Jazira playmaker has for some time been tipped for stardom within UAE football, with Quique Sanchez Flores, his former manager at Al Ahli, once labelling him a “genius”. He was only 17. Now 23, Mubarak has developed into a crafty supplier of chances, evidenced by his seven assists in six league matches this season. Still to display his class at international level, though.
Rayan Yaslam
The Al Ain attacking midfielder has become a regular starter for his club in the past 15 months. Yaslam, 23, is a tidy and intelligent player, technically proficient with an eye for opening up defences. Developed while alongside Abdulrahman in the Al Ain first-team and has progressed well since manager Zoran Mamic’s arrival. However, made his UAE debut only last December.
Ismail Matar
The Al Wahda forward is revered by teammates and a key contributor to the squad. At 35, his best days are behind him, but Matar is incredibly experienced and an example to his colleagues. His ability to cope with tournament football is a concern, though, despite Matar beginning the season well. Not a like-for-like replacement, although the system could be adjusted to suit.

What is the FNC?
The Federal National Council is one of five federal authorities established by the UAE constitution. It held its first session on December 2, 1972, a year to the day after Federation.
It has 40 members, eight of whom are women. The members represent the UAE population through each of the emirates. Abu Dhabi and Dubai have eight members each, Sharjah and Ras al Khaimah six, and Ajman, Fujairah and Umm Al Quwain have four.
They bring Emirati issues to the council for debate and put those concerns to ministers summoned for questioning.
The FNC’s main functions include passing, amending or rejecting federal draft laws, discussing international treaties and agreements, and offering recommendations on general subjects raised during sessions.
Federal draft laws must first pass through the FNC for recommendations when members can amend the laws to suit the needs of citizens. The draft laws are then forwarded to the Cabinet for consideration and approval.
Since 2006, half of the members have been elected by UAE citizens to serve four-year terms and the other half are appointed by the Ruler’s Courts of the seven emirates.
In the 2015 elections, 78 of the 252 candidates were women. Women also represented 48 per cent of all voters and 67 per cent of the voters were under the age of 40.
