Pre-Pottery Neolithic B (PPNB) is part of thePre-Pottery Neolithic, aNeolithic culture centered inupper Mesopotamia and theLevant, dating toc. 10,800 – c. 8,500 years ago, that is, 8800–6500 BC.[1] It wastyped by British archaeologistKathleen Kenyon during herarchaeological excavations atJericho in theWest Bank, territory ofPalestine.
Like the earlierPPNA people, the PPNB culture developed from theMesolithicNatufian culture. However, it shows evidence of having more northerly origins, possibly indicating an influx from the region of northeasternAnatolia.
Cultural tendencies of this period differ from that of the earlierPre-Pottery Neolithic A (PPNA), in that people living during this phase began to depend more heavily upondomesticated animals to supplement their earlier mixed agrarian andhunter-gatherer diet. In addition, theflint tool kit of the period is new and quite disparate from that of the earlier period. One of its major elements is thenaviform core. This is the first period in which architectural styles of the southern Levant became primarilyrectilinear; earlier typical dwellings were circular, elliptical and occasionally even octagonal. Pyrotechnology, the expanding capability to control fire, was highly developed in this period. During this period, one of the main features of houses is a thick layer of white clay plaster flooring, highly polished and made of lime produced fromlimestone.
It is believed that the use of clay plaster for floor and wall coverings during PPNB led to the discovery ofpottery.[2] The earliest proto-pottery wasWhite Ware vessels, made from lime and gray ash, built up around baskets before firing, for several centuries around 7000 BC at sites such as TellNeba'a Faour (Beqaa Valley).[3] Sites from this period found in the Levant utilizing rectangular floor plans and plastered floor techniques were found atAin Ghazal,Yiftahel (westernGalilee), andAbu Hureyra (UpperEuphrates).[2] The period is dated to between c. 10,700 and c. 8,000BP or 8,700–6,000 BC.
Plastered human skulls were reconstructed human skulls that were made in the ancientLevant between 9000 and 6000 BC in the Pre-Pottery Neolithic B period. They represent some of the oldest forms of art in theMiddle East and demonstrate that the prehistoric population took great care in burying theirancestors below their homes. The skulls denote some of the earliest sculptural examples ofportraiture in thehistory of art.[4]
Danielle Stordeur's recent work atTell Aswad, a large agricultural village betweenMount Hermon andDamascus could not validateHenri de Contenson's earlier suggestion of a PPNAAswadian culture. Instead, they found evidence of a fully established PPNB culture at 8700 BC at Aswad, pushing back the period's generally accepted start date by 1,200 years. Similar sites toTell Aswad in the Damascus Basin of the same age were found atTell Ramad andTell Ghoraifé. How a PPNB culture could spring up in this location, practicing domesticated farming from 8700 BC has been the subject of speculation. Whether it created its own culture or imported traditions from the North East orSouthern Levant has been considered an important question for a site that poses a problem for the scientific community.[5][6][7][8][9][10][11][12]
Work at the site of'Ain Ghazal inJordan has indicated a laterPre-Pottery Neolithic C period, which existed between 8,200 and 7,900 BP.Juris Zarins has proposed that a Circum Arabian Nomadic Pastoral Complex developed in the period from the climatic crisis of 6200 BC, partly as a result of an increasing emphasis in PPNB cultures upon animal domesticates, and a fusion withHarifian hunter gatherers in Southern Palestine, with affiliate connections with the cultures ofFayyum and theEastern Desert ofEgypt. Cultures practicing this lifestyle spread down theRed Sea shoreline and moved east fromSyria into southernIraq.[13]
The culture disappeared during the8.2 kiloyear event, a term thatclimatologists have adopted for a sudden decrease in global temperatures that occurred approximately 8,200 years before the present, or c. 6200 BC, and which lasted for the next two to four centuries. In the followingMunhatta andYarmukian post-pottery Neolithic cultures that succeeded it, rapid cultural development continues, although PPNB culture continued in theAmuq valley, where it influenced the later development of theGhassulian culture.
Around 8000 BC, before the invention of pottery, several early settlements became experts in crafting beautiful and highly sophisticated containers from stone, using materials such asalabaster orgranite, and employing sand to shape and polish. Artisans used the veins in the material to maximum visual effect. Such objects have been found in abundance on the upperEuphrates river, in what is today eastern Syria, especially at the site ofBouqras.[14] These form the early stages of the development of theart of Mesopotamia.
Pre-Pottery Neolithic B fossils that were analysed for uniparentals via ancient DNA, were found to carry the Y-DNA (paternal) haplogroupsE1b1b (2/7; ~29%),CT (2/7; ~29%),E(xE2,E1a,E1b1a1a1c2c3b1,E1b1b1b1a1,E1b1b1b2b) (1/7; ~14%),T(xT1a1,T1a2a) (1/7; ~14%), andH2 (1/7; ~14%). The CT clade was also observed in a Pre-Pottery Neolithic C specimen (1/1; 100%).[15] Maternally, the rare basal haplogroupN* has been found among skeletal remains belonging to the Pre-Pottery Neolithic B,[16] as have the mtDNA cladesL3[16] andK.[17]
DNA analysis has also confirmed ancestral ties between the Pre-Pottery Neolithic culture bearers and the makers of the EpipaleolithicIberomaurusian culture of North Africa,[18] the MesolithicNatufian culture of the Levant, theSavanna Pastoral Neolithic culture of East Africa,[19] the Early NeolithicCardium culture of Morocco,[20] and theAncient Egyptian culture of the Nile Valley,[21] with fossils associated with these early cultures all sharing a common genomic West Eurasian/Near-Eastern component.[20] A paper from 2021 would find that the Mesolithic Natufians cluster the closest with modern Saudi Arabians, Desert Bedouins and Yemenis. The Natufians were also close to, and ancestral to the ancient Levant PPNB/C and the later Levantine Bronze Age samples.[22]
Mathieson et al. (2015) & Lazardis et al. (2016), discovered that the Levant Neolithic samples from PPNB to PPNC were a mix of a component related to Natufians, and another lineage related toAnatolian farmers from Barcin and Mentese.[23][24] In another study from 2021, the populations of the PPNB Levant were modelled as having 60.5% Israel Natufian Epipaleolithic related ancestry, and 39.5% Turkey Barcin Neolithic ancestry. Later, geneticists in 2022 using 1.2 million single nucleotide polymorphisms (SNPs), discovered that the ancient DNA of the Pre-Pottery Neolithic of Mesopotamia and Anatolia, showed that these populations were formed through admixture of pre-Neolithic sources related toAnatolian,Caucasus, and Levantine hunter-gatherers.[25]
Altınışık, N Ezgi et al. (2022) studied 13 genomes from the PPNB atCayonu, Turkey, and found they were formed by an admixture event between western and eastern populations of early Holocene Southwest Asia.[26]
In 2023, Xiaoran Wang and team found that their six genetically analyzed PPNB individuals, were having ancestry from Levantine Epipaleolithic, Anatolian Neolithic,Iranian Neolithic, and Caucasus Hunter-Gatherers. The PPNB in general exhibited strong evidence of gene flow from populations related to Anatolia compared to the earlier Natufian hunter-gatherers. PPN individuals from Ain Ghazal further to the north in Jordan had a stronger genetic affinity with Anatolia than the PPN of Ba'ja, although not significantly so.[27]
The spread of theNeolithic in Europe was first studied quantitatively in the 1970s, when a sufficient number of 14C age determinations for early Neolithic sites had become available.[28]Ammerman andCavalli-Sforza discovered a linear relationship between the age of an Early Neolithic site and its distance from the conventional source in the Near East (Jericho), thus demonstrating that, on average, the Neolithic spread at a constant speed of about 1 km/yr.[28] More recent studies confirm these results and yield the speed of 0.6–1.3 km/yr at 95% confidence level.[28]
Since the original human expansions out of Africa 200,000 years ago, different prehistoric and historic migration events have taken place in Europe.[29] Considering that the movement of the people implies a consequent movement of their genes, it is possible to estimate the impact of these migrations through the genetic analysis of human populations.[29] Agricultural and husbandry practices originated 10,000 years ago in a region of the Near East known as the Fertile Crescent.[29] According to the archaeological record this phenomenon, known as "Neolithic", rapidly expanded from these territories into Europe.[29] However, whether this diffusion was accompanied or not by human migrations is greatly debated.[29]Mitochondrial DNA – a type of maternally inherited DNA located in the cell cytoplasm- was recovered from the remains of Pre-Pottery Neolithic B (PPNB) farmers in the Near East and then compared to available data from other Neolithic populations in Europe and also to modern populations from South Eastern Europe and the Near East.[29] The obtained results show that substantial human migrations were involved in the Neolithic spread and suggest that the first Neolithic farmers entered Europe following a maritime route throughCyprus and theAegean Islands.[29]
