Mehrgarh

Mehrgarh sometimes anglicized as Mehergarh or Mehrgar, is a Neolithic (7000 BCE to c. 2500/2000 BCE) site located near the Bolan Pass on the Kacchi Plain of Balochistan, Pakistan, to the west of the Indus River valley.

The earliest settlement at Mehrgarh, in the northeast corner of the 495-acre (2.00 km²) site, was a small farming village which was inhabited from circa 6500 BCE. It is one of the earliest sites with evidence of farming and herding in South Asia. The site was discovered in 1974 by an archaeological team led by French archaeologists Jean-François Jarrige and Catherine Jarrige, and was excavated continuously between 1974 and 1986, and again from 1997 to 2000. Archaeological material has been found in six mounds, and about 32,000 artifacts have been collected.
 
Mehrgarh is now seen as a precursor to the Indus Valley Civilization, displaying the whole sequence from earliest settlement and the start of agriculture, to the mature Harappan Civilisation.

Jean-Francois Jarrige argues for an independent origin of Mehrgarh. Jarrige notes "the assumption that farming economy was introduced full-fledged from Near-East to South Asia," and the similarities between Neolithic sites from eastern Mesopotamia and the western Indus valley, which are evidence of a "cultural continuum" between those sites. But given the originality of Mehrgarh, Jarrige concludes that Mehrgarh has an earlier local background," and is not a "'backwater' of the Neolithic culture of the Near East."

According to Lukacs and Hemphill, while there is a strong continuity between the neolithic and chalcolithic (Copper Age) cultures of Mehrgarh, dental evidence shows that the chalcolithic population did not descend from the neolithic population of Mehrgarh, which "suggests moderate levels of gene flow." They wrote that "the direct lineal descendents of the Neolithic inhabitants of Mehrgarh are to be found to the south and the east of Mehrgarh, in northwestern India and the western edge of the Deccan plateau," with neolithic Mehrgarh showing greater affinity with chalocolithic Inamgaon, south of Mehrgarh, than with chalcolithic Mehrgarh.

Gallego Romero et al. (2011) state that their research on lactose tolerance in India suggests that "the west Eurasian genetic contribution identified by Reich et al. (2009) principally reflects gene flow from Iran and the Middle East." Gallego Romero notes that Indians who are lactose-tolerant show a genetic pattern regarding this tolerance which is "characteristic of the common European mutation." According to Romero, this suggests that "the most common lactose tolerance mutation made a two-way migration out of the Middle East less than 10,000 years ago.

While the mutation spread across Europe, another explorer must have brought the mutation eastward to India – likely traveling along the coast of the Persian Gulf where other pockets of the same mutation have been found." They further note that "[t]he earliest evidence of cattle herding in south Asia comes from the Indus River Valley site of Mehrgarh and is dated to 7,000 YBP.

Archaeologists divide the occupation at the site into eight periods.

The Mehrgarh Period I (7000 BCE-5500 BCE) was Neolithic and aceramic, without the use of pottery. The earliest farming in the area was developed by semi-nomadic people using plants such as wheat and barley and animals such as sheep, goats and cattle. The settlement was established with simple mud buildings and most of them had four internal subdivisions. Numerous burials have been found, many with elaborate goods such as baskets, stone and bone tools, beads, bangles, pendants and occasionally animal sacrifices, with more goods left with burials of males. Ornaments of sea shell, limestone, turquoise, lapis lazuli and sandstone have been found, along with simple figurines of women and animals. Sea shells from far sea shore and lapis lazuli found as far away as present-day Badakshan, Afghanistan shows good contact with those areas. A single ground stone axe was discovered in a burial, and several more were obtained from the surface. These ground stone axes are the earliest to come from a stratified context in South Asia. Periods I, II and III are contemporaneous with another site called Kili Gul Mohammed.

In 2001, archaeologists studying the remains of two men from Mehrgarh made the discovery that the people of the Indus Valley Civilization had knowledge of proto-dentistry from the early Harappan periods. In April 2006, it was announced in the scientific journal Nature that the oldest (and first early Neolithic) evidence for the drilling of human teeth in vivo (i.e. in a living person) was found in Mehrgarh. According to the authors, their discoveries point to a tradition of proto-dentistry in the early farming cultures of that region. "Here we describe eleven drilled molar crowns from nine adults discovered in a Neolithic graveyard in Pakistan that dates from 7,500 to 9,000 years ago. These findings provide evidence for a long tradition of a type of proto-dentistry in an early farming culture.

 The Mehrgarh Period II (5500 BCE–4800 BCE) and Merhgarh Period III (4800 BCE–3500 BCE) were ceramic Neolithic, using pottery, and later chalcolithic. Period II is at site MR4 and Period III is at MR2. Much evidence of manufacturing activity has been found and more advanced techniques were used. Glazed faience beads were produced and terracotta figurines became more detailed. Figurines of females were decorated with paint and had diverse hairstyles and ornaments. Two flexed burials were found in Period II with a red ochre cover on the body. The amount of burial goods decreased over time, becoming limited to ornaments and with more goods left with burials of females.

The first button seals were produced from terracotta and bone and had geometric designs. Technologies included stone and copper drills, updraft kilns, large pit kilns and copper melting crucibles. There is further evidence of long-distance trade in Period II: important as an indication of this is the discovery of several beads of lapis lazuli, once again from Badakshan. Mehrgarh Periods II and III are also contemporaneous with an expansion of the settled populations of the borderlands at the western edge of South Asia, including the establishment of settlements like Rana Ghundai, Sheri Khan Tarakai, Sarai Kala, Jalilpur and Ghaligai.

 Period IV was 3500 to 3250 BCE. Period V from 3250 to 3000 BCE and period VI was around 3000 BCE. The site containing Periods IV to VII is designated as MR1.

 Somewhere between 2600 BCE and 2000 BCE, the city seems to have been largely abandoned in favor of the larger and fortified town Nausharo five miles away when the Indus Valley Civilization was in its middle stages of development. Historian Michael Wood suggests this took place around 2500 BCE.

The last period is found at the Sibri cemetery, about 8 kilometers from Mehrgarh.

Early Mehrgarh residents lived in mud brick houses, stored their grain in granaries, fashioned tools with local copper ore, and lined their large basket containers with bitumen. They cultivated six-row barley, einkorn and emmer wheat, jujubes and dates, and herded sheep, goats and cattle. Residents of the later period (5500 BCE to 2600 BCE) put much effort into crafts, including flint knapping, tanning, bead production, and metal working. Mehrgarh is probably the earliest known center of agriculture in South Asia.
The oldest known example of the lost-wax technique comes from a 6,000-year-old wheel-shaped copper amulet found at Mehrgarh. The amulet was made from unalloyed copper, an unusual innovation that was later abandoned.
