Bere Barley, a "Neolithic" Grain

 

Bere Barley, a "Neolithic" Grain





Bere, pronounced “bear” is a six-row barley which when milled becomes Bere Meal. It is still grown and used today in Orkney to make a traditional flatbread called a Bannock. It is probably Britain’s oldest cereal in continuous commercial cultivation.

The domestication of the Bere Barley grain is likely to have begun soon after the retreat of the last ice age, when plants, animals, and humans first colonised the vast plains of the North European continental shelf, an area east, west, and north of Orkney.

The grain probably initially adapted itself to the local climatic conditions, and the process of domestication was continued when humans would collect the heads of the primitive wild barley, selecting for size to make the nutritional content of the cereal worth the effort of extracting it from the seed head.

The theory implies that the continued viability of seeds or grains as they were carried into higher latitudes required them to be adapted to environmental conditions starkly different to those under which they were first domesticated.

The plant that is created under these circumstances is known as a “landrace”, which is defined as a domesticated, locally adapted, traditional variety of a species of animal or plant that has developed over time, through adaptation to its environment and isolation from other populations of the species.

Bere Barley, Hordeum Vulgare L. , is the ancient grains that is found on the Outer Hebrides and Orkney.

“Barley (Hordeum vulgare ssp. Vulgare) was one of the first and earliest crops domesticated by humans. Currently, archaeological and genetic evidence indicates barley is a mosaic crop, developed from several populations in at least five regions: Mesopotamia, the northern and southern Levant, the Syrian desert and, 900–1,800 miles (1,500–3,000 kilometers) to the east, in the vast Tibetan Plateau.

The wild progenitor of all of the barleys is thought to be Hordeum spontaneum (L.), a winter-germinating species which is native to a very wide region of Eurasia, from the Tigris and Euphrates river system in Iraq to the western reaches of the Yangtze River in China. Based on evidence from Upper Paleolithic sites such as Ohalo II in Israel, wild barley was harvested for at least 10,000 years before it was domesticated.

Barley as a whole is well-adapted to marginal and stress-prone environments, and a more reliable plant than wheat or rice in regions which are colder or higher in altitude.”(Hirst)

Rather than an imported grain, modified by human agency, Bere Barley was probably self-adapted.

Different environmental conditions exist in Orkney, compared to those normally found over much of Eurasia.

I hesitate to call anywhere unique, but there are things that make the northern Isles different, and create a different climate, and radically different weather and seasons.

Chief among the factors that condition the climate here is its location on the planet. The gulf Stream is a constant flow of equatorial water that pushes up the Atlantic ocean towards the Arctic ocean bringing warmth to the British Isles. It also brings violent winds to Orkney.

"Searching for the Origins of Bere Barley: a GeometricMorphometric Approach to Cereal LandraceRecognition in Archaeology" by M. Wallace et al.

"The spread of agriculture beyond the regions of cereal domestication in the FertileCrescent of southwest Asia was a lengthy process crossing biogeographic boundaries.Following initial expansion through Anatolia and to Cyprus, domesticated crops reachedsoutheast Europe c.8500 yrs BP, and from there were dispersed along two main routes: a southern route along the Mediterranean, reaching the Iberian peninsula c.7500 yrs BP, anda northwards route passing through central Europe by c.7500 yrs BP and eventuallyreaching northern Scotland c.6000 yrs BP (Bocquet-Appel et al. 2009; Fort 2015). Thecontinued viability of agriculture as it spread across Europe, especially along the latternorthwards trajectory, required crops to adapt to environmental conditions starkly differentto those under which they were first domesticated (Bogucki 2000; Bonsall et al. 2002;Halstead 1989). This is exemplified by adaptations in responsiveness to daylength with thenorthwards spread of agriculture (Jones et al. 2012) and observed adaptation to specificabiotic stresses (George et al. 2014; Schmidt et al. in prep.). Adaptation in crop specieswould have come about through periods of stable cultivation on the edges of newenvironments, leading to the emergence of new, locally adapted landraces."

The Orkney Vole

The Orkney Vole " Much debate surrounds the origins of the Orkney vole Microtus arvalis orcadensis (Yalden 1999; Corbet 1961). It is the only vole on Orkney and is found on eight islands, while in mainland Britain the field vole (M. agrestis) is the only Microtus species. M. arvalis and M. agrestis occur widely across continental Europe with overlapping distributions (Mitchell-Jones et al 2003). It is therefore clear that M. arvalis did not colonise Orkney naturally (Haynes et al 2003; Haynes et al 2004), and although modern consensus supports a human introduction during the Neolithic (Hedges et al 1987), their geographic origin and mechanisms of introduction still remain uncertain ."

Neolithic Migration to Orkney

Image
  The Story of the Neolithic Migration to Orkney  The Neolithic people of Britain were a nomadic group of cultures that entered the country from the Dutch region of northern Europe from before 7000 years ago until after 6000 years ago. They came on foot, across a land bridge that is now shallow water between Holland and East Anglia, in England.  These people brought with them a suite of technologies ,  including pottery, domesticated animals, landscape structures, economic systems, community activities, timber joinery, structural engineering, and small-scale industries. They had boats , but these were limited to dugout canoes for use on inland waters, lakes, harbours, and perhaps for crossing rivers. These were people who had arrived in Northern Europe from the south, gathering in the Scheldt valley. As a group of various peoples we call these the Swifterbant Culture , and it was much later that the various groups included here, having established mobile populati...

Archaeology in the North Sea

  Archaeology in the North Sea   The Orkney Vole is thought to have been imported, by uncertain means, to the archipelago from mainland Europe without setting foot on mainland Britain.  How this happened is a bit of a mystery.  Summary A complex series of shallow inland seas "The Marr Bank Lagoon" were carved out along the east coast of Britain from about 70,000BP. They were not directly connected to the Norwegian Channel or the Norwegian Coast, but were separated from it by a ridge of land , north from Dogger Bank to the Atlantic Ocean.  In this period from 70,000BP to 40,000BP the mountains of northern England and Scotland were capped with thick snow, and the Shetland icecap was in a continual condition of collapse, blocking the Marr Bank Lagoon   at the north.  The Marr Bank Lagoon was surrounded by a shoreline which was backed onto the icesheet on all sides. Evidence suggests that the Lagoon did not freeze over. At around 40,000BP animals and ...
