Does Drilled Tooth Enamel Prove Ancient Dentistry? - Mehrgarh and the Aceramic Neolithic in South Asia | Sleepy Facts About History · Sleepy Facts About History

Welcome to Sleepy Facts About History. When we
0:12
think of the Neolithic era, we usually picture
0:15
a package deal, farming, permanent villages,
0:18
and pottery all arriving together. But the ancient
0:22
settlement of Mergar, located on the Karchi plain
0:26
in what is now Pakistan, breaks that assumption
0:29
entirely. 7 ,000 years before the Common Era,
0:33
people were farming wheat and barley. herding
0:36
cattle, and building mud -brick homes without
0:39
making a single ceramic vessel. For over 4 ,000
0:44
years, this community thrived at the foot of
0:47
the Borland Pass, using bitumen -coated baskets
0:50
for storage and developing sophisticated craft
0:53
traditions. This episode examines the deep archaeological
0:58
record of Maegar to understand how early South
1:01
Asian agriculture actually developed. We explore
1:05
how domesticated crops and animals reached the
1:08
region through inter -regional exchange, how
1:11
the site participated in long -distance trade
1:13
from materials like lapis lazuli, and how the
1:17
eventual arrival of pottery marked a technological
1:19
shift, rather than a revolutionary break. We
1:24
also look at the remarkable discovery of drilled
1:26
human teeth to understand what they tell us about
1:29
early technical skill. and what they do not tell
1:32
us about ancient medical professions. I kept
1:36
returning to one question while working on this
1:39
episode. Why do we assume human progress moves
1:43
in a single predictable line? Looking at Maegar
1:47
reveals a much more interesting reality. The
1:50
people here were not waiting for civilization
1:52
to begin, nor were they simply a preliminary
1:55
step toward the later Indus cities. They were
1:59
active. creative participants in their own world,
2:02
adapting outside influences and developing local
2:05
traditions across deep time. Understanding their
2:09
long, gradual history offers a far more accurate
2:12
picture of how human societies learn to live
2:14
differently. At Maegar, on the edge of the Bolan
2:21
Pass, people were already farming wheat and herding
2:24
cattle 7 ,000 years before the Common Era. They
2:28
did this without pottery, without cities. Without
2:32
any of the things we usually assume must come
2:34
together, what they had was time. More than 4
2:40
,000 years of living, burying their dead with
2:43
beads of lapis lazuli from Afghanistan, coating
2:46
baskets with bitumen to store grain, and drilling
2:49
teeth with flint tools. All of this happened
2:53
while the mountains behind them kept open a corridor
2:56
to the wider world. Imagine a small village at
3:00
the edge of a mountain pass. 7 ,000 years before
3:04
the Common Era. The houses are built of mud brick,
3:07
shaped by hand from the local clay and left to
3:10
dry in the sun. Inside them, people store grain
3:15
in baskets coated with a dark, sticky substance
3:18
to keep out moisture. Outside, fields of wheat
3:23
and barley grow on the alluvial soils of a broad
3:25
plain. Cattle, sheep, and goats are herded in
3:30
nearby pastures. When someone dies, they are
3:34
buried in the ground near the houses, with selected
3:37
objects placed beside them. Perhaps beads of
3:41
blue stone. Perhaps a favorite tool. There is
3:46
no pottery here yet. That will come later, more
3:50
than a thousand years later in fact. This is
3:53
not the dramatic beginning of farming in South
3:56
Asia. It is something more interesting than that.
4:00
It is a community already living with agriculture.
4:03
already connected to wider networks, already
4:06
experimenting with how to organize their lives
4:09
around plants, animals, and each other. This
4:12
is Mergar on the Karchi Plain of what is now
4:15
Pakistani Balochistan at the foot of the Bolan
4:18
Pass. And the question this episode asks is not
4:23
what single thing began here, but what generations
4:26
of farmers were doing to cross the more than
4:28
4 ,000 years that this place was occupied. To
4:33
understand why this matters, we need to clear
4:35
away some common assumptions. Many people, if
4:39
they have heard of the Indus Valley civilization
4:41
at all, know Harappa and Mohenjo -daro. They
4:46
know the great cities with their planned streets,
4:48
their sophisticated drainage, their standardized
4:51
weights and measures. It is tempting to imagine
4:55
that these cities emerged suddenly, almost miraculously,
4:59
from a landscape that had been waiting empty.
5:02
or to assume that farming in South Asia must
5:05
have begun at one identifiable moment, at one
5:08
special place, perhaps imported wholesale from
5:11
somewhere else. Magar complicates all of this.
5:15
It shows us that farming, herding, craft production,
5:20
and settled village life developed gradually
5:23
across millennia, in specific places with specific
5:26
histories. as part of wider regional processes
5:29
that connected local people with distant networks.
5:33
The site was discovered in 1974 by French archaeologists
5:38
Jean Francois and Catherine Gerrige. Excavations
5:43
by the French archaeological mission to Pakistan
5:46
through the following decades revealed a remarkably
5:48
deep and continuous sequence of occupation. What
5:52
they found was not a single revolutionary moment,
5:55
but a long, layered record. of people learning
5:58
to live differently the location itself tells
6:02
us something important marigas sits on the kachi
6:06
plain west of the indus river at the foot of
6:10
the bolan pass this pass is one of the main routes
6:14
connecting the indus valley with the iranian
6:17
plateau and regions further to the west the plane
6:22
offers alluvial soils that can be cultivated
6:24
seasonal water sources and access to both highland
6:29
and lowland resources. These include mountain
6:32
pastures, riverine floodplains, mineral deposits,
6:36
and trade routes. The environment was favorable
6:40
for early farming and herding, but it was also
6:43
a place of connection. People at Maegar were
6:47
not isolated pioneers. They were participants
6:50
in networks that stretched across mountains and
6:53
valleys. Their material lives reflect this dual
6:56
character of local adaptation and inter -regional
7:00
exchange. The earliest levels at Mergar, designated
7:05
period I and dated to approximately 7000 -5500
7:09
BCE, are aceramic. That is, they lack pottery
7:15
entirely. This is worth pausing over. because
7:19
pottery is so often associated with the Neolithic
7:22
that we might assume it arrived as part of a
7:24
package with farming and settled life. At Mergar,
7:28
it did not. The earliest farmers here had agriculture,
7:33
architecture, storage technologies, craft production,
7:37
and burial practices, but they did not make pottery.
7:41
Instead, they used baskets coated with bitumen.
7:45
a naturally occurring tar -like substance to
7:48
store and carry goods. These were not crude temporary
7:52
containers awaiting something better. A bitumen
7:56
-coated basket would have felt substantial in
7:59
the hands. Woven plant fibers darkened and stiffened
8:03
by the thick, slightly tacky coating. The bitumen
8:06
pressed into every gap between the strands to
8:09
form a seal against moisture and insects. The
8:13
weight of a full basket of grain would have been
8:16
considerable. The dark surface would have caught
8:19
the light differently from the pale woven fibers
8:22
beneath. The bitumen worked by filling the microscopic
8:25
spaces between woven fibers, creating a barrier
8:29
that water and pests could not easily cross.
8:33
This was a technology that required knowledge
8:36
of local plant materials, of where to find bitumen
8:39
and how to heat and apply it. of how to shape
8:43
a container that would hold together under weight
8:45
and over time. They built multi -roomed rectangular
8:49
structures of mud brick, some used for living,
8:53
others apparently for storage. They cultivated
8:56
domesticated wheat and barley, and they herded
9:00
cattle, sheep and goats, and they buried their
9:04
dead, sometimes within the settlement itself,
9:07
with selected grave goods. These included beads,
9:12
baskets and stone tools the grave goods suggest
9:16
care and mortuary practice and perhaps some notion
9:19
of what a person might need or what might signify
9:22
their identity in death the significance of this
9:25
aceramic neolithic is that it separates elements
9:28
we might otherwise bundle together farming does
9:32
not require pottery settled life does not require
9:36
pottery these were separate developments And
9:40
at Mergar, we can see them unfolding on different
9:43
timelines. The people of Period I were not incomplete
9:47
or preliminary farmers. They were fully engaged
9:51
in an agricultural way of life, with all the
9:54
scheduling, storage, labor organization, and
9:58
risk management that farming entails. They had
10:01
simply not adopted or developed ceramic technology.
10:05
When pottery does appear in Period VII, Around
10:08
5500 BCE, it represents a technological shift
10:12
but not a fundamental economic or social transformation.
10:17
The village continues. The farming continues.
10:21
The herding continues. Something new has been
10:25
added, not something essential supplied at last.
10:29
This brings us to the material evidence for craft
10:33
production and technological change across the
10:35
early periods. This evidence is remarkably rich
10:39
at Mergar, and essential for understanding how
10:42
this community functioned. The basketry and bitumen
10:46
-coated containers of the aceramic levels are
10:50
sophisticated technologies in their own right.
10:53
They required knowledge of part fibers, of bitumen
10:57
sources and properties, of shaping and sealing.
11:00
These containers would have been used for storing
11:03
grain and other goods. Their manufacture implies
11:07
both specialized knowledge and the social organization
11:10
to produce and distribute them. More visually
11:14
striking is the evidence for bead making. Beads
11:17
at Mehrgarh were produced from materials including
11:20
lapis lazuli, a deep blue stone mined in northeastern
11:24
Afghanistan, turquoise from Iranian sources,
11:27
and marine shell from the Arabian Sea coast.
11:31
The presence of these materials is concrete evidence
11:34
for long -distance exchange networks. Someone
11:38
at Mergar, or someone in contact with Mergar,
11:41
had access to resources from hundreds of kilometers
11:43
away. The beads themselves required skill to
11:48
manufacture. This involved drilling, grinding,
11:52
and polishing. They appear in burials, as well
11:55
as in domestic contexts. suggesting that they
11:58
carried social and perhaps symbolic significance
12:01
beyond mere decoration. A bead of lapis lazuli,
12:05
that particular intense blue, would have stood
12:08
out dramatically against the brown landscape
12:11
and the earthen tones of mud brick and basketry.
12:15
Held in hand, it would have caught even dim light,
12:18
the drilled perforation visible as a small dark
12:22
core running through the coloured stone. It was
12:26
a material connection to distant places, transformed
12:29
by local craft into objects of value and meaning.
12:33
Stone tools at Magar also show development across
12:37
time. The earliest levels feature blades and
12:40
scrapers made from local materials. These were
12:44
tools for cutting plant stalks, for processing
12:47
grain and animal hides for working wood and bone.
12:51
The manufacturing required skill. It involved
12:55
striking or pressure flaking stone to create
12:58
sharp edges, then retouching them for specific
13:01
tasks. Over time, tool types and manufacturing
13:06
methods changed, reflecting both local experimentation
13:09
and continued connection to wider technological
13:13
networks. The stone tool industry was not static
13:17
or primitive. It was a dynamic craft responsive
13:20
to changing needs and opportunities. and it supported
13:24
the agricultural and domestic activities of the
13:27
community. The appearance of pottery in period
13:30
II, around 5500 BCE, marks a significant technological
13:35
development without being a revolutionary break.
13:39
Ceramic technology requires knowledge of clay
13:42
sources, tempering materials, firing temperatures
13:45
and shaping techniques. Its adoption at Mergar.
13:50
after more than a thousand years of aceramic
13:52
occupation suggests either gradual local experimentation
13:55
or the adoption of practices from elsewhere more
13:59
likely it involved some combination of both once
14:03
established pottery became a durable and versatile
14:07
medium for storage cooking and serving it appears
14:11
in increasingly varied forms in later periods
14:14
But its late arrival relative to other elements
14:17
of the Neolithic package reminds us that technological
14:20
change is not uniform or predetermined. Different
14:24
communities adopted different innovations at
14:27
different times according to their own circumstances
14:29
and connections. The question of connections
14:33
with regions to the West is central to understanding
14:36
Mergar, and it requires careful handling. The
14:40
domesticated wheat and barley found in the earliest
14:43
levels are species that were first domesticated
14:46
in the Middle East, in the Fertile Crescent region.
14:50
Similarly, sheep and goats were domesticated
14:53
in Western Asia before they appear at Mergar.
14:56
This means that these crops and animals reach
14:59
the Kharchi plain through networks of some kind.
15:03
This may have happened through the movement of
15:05
people, the exchange of goods and knowledge,
15:08
or some combination. The precise mechanisms remain
15:12
debated among scholars. The evidence does not
15:15
allow us to specify whether this involved migration,
15:18
trade or the gradual diffusion of practices across
15:22
generations. What we can say is that Mergar was
15:26
not an isolated local invention of agriculture.
15:29
It was a community that adopted and adapted domesticated
15:33
species from elsewhere, incorporating them into
15:36
local practices and local environments. The wheat
15:40
and barley that grew on the Kharchi plain were
15:42
not identical to their Middle Eastern ancestors.
15:45
They had been selected, cultivated, and probably
15:49
modified through generations of local farming.
15:52
The sheep and goats herded at Megar became part
15:56
of a local pastoral economy, integrated with
15:59
cattle herding and crop cultivation in ways that
16:02
reflected local conditions and choices. And all
16:06
of this movement of crops, animals, materials,
16:10
knowledge, passed through or near the Bolan Pass.
16:13
This was the visible gap in the mountains behind
16:17
the village. The corridor that connected the
16:19
Karchi plain to the Iranian plateau and beyond.
16:23
When the people of Mergar looked up from their
16:26
fields, they saw the mountains rising to the
16:29
west. They knew the pass that cut through them.
16:32
The route that brought Lapis Lazuli. and turquoise
16:36
and new ways of doing things. This is where the
16:40
Zebu cattle become particularly important. Zebu,
16:44
or Bos Indicus, are the humped cattle characteristic
16:48
of South Asia. They represent a distinct domestication
16:53
history from the Taurean cattle, Bostorus, of
16:56
the Middle East and Europe. The presence of Zebu
17:00
remains at Magar. Identified through osteological
17:03
analysis, indicates that local South Asian domestication
17:07
processes were underway alongside the adoption
17:10
of Western species. This is not evidence that
17:14
Zebu were domesticated at Megar itself. The origins
17:18
of Zebu domestication remain uncertain and likely
17:21
involve multiple regions and processes across
17:24
the subcontinent. but it is evidence that the
17:28
people of Mergar were participating in distinctively
17:31
South Asian developments as well as in wider
17:34
inter -regional networks. Their agricultural
17:38
economy was neither purely imported nor purely
17:41
local. It was a hybrid, shaped by connection
17:45
and adaptation over long periods. The dual process
17:50
of connection and local development is one of
17:53
the most important patterns that Mergar reveals.
17:56
We might be tempted to frame this as a simple
17:59
story of outside influence or, conversely, of
18:03
indigenous resistance. Neither framing captures
18:07
what the archaeological evidence actually shows.
18:10
The people of Mergar were not passive recipients
18:13
of a Neolithic package brought from the West.
18:17
They were active participants in networks that
18:20
moved crops, animals, materials, technologies
18:23
and knowledge across considerable distances.
18:27
They were simultaneously developing local practices,
18:30
local breeds, local traditions of craft and architecture
18:34
and burial that cannot be explained by outside
18:38
influence alone. The lapis lazuli beads, the
18:43
zebu cattle, the mud brick houses, the bitumen
18:47
coated baskets, all of these coexist in the archaeological
18:52
record. and they demand an interpretation that
18:55
allows for both connection and creativity. This
18:59
brings us to one of the most remarkable and most
19:02
misinterpreted pieces of evidence from Mecca,
19:05
the drilled teeth. In Neolithic burials dating
19:09
to approximately 7000 -5500 BCE, archaeologists
19:14
found human molars that had been deliberately
19:17
drilled. These were small, precise holes made
19:20
with flint -tip tools, apparently using a bow
19:23
drill or similar rotary mechanism. The drilling
19:27
shows considerable skill. A flint tip rotated
19:31
by a bow or similar device would have cut slowly
19:35
through the hard enamel. This required steady
19:38
pressure and precise control to avoid cracking
19:41
the tooth or injuring the surrounding tissue.
19:44
The holes are clean, controlled and in some cases
19:47
appear to have been made with awareness of tooth
19:50
anatomy. The process would have been painful
19:53
and slow. This makes both the skill of the operator
19:57
and the willingness of the subject significant.
20:00
This is one of the earliest known examples of
20:03
dental intervention anywhere in the world and
20:06
it is genuinely remarkable. But it is also easily
20:10
misinterpreted. The popular imagination and sometimes
20:15
even scholarly commentary has been tempted to
20:18
see these drilled teeth as evidence of a universal
20:21
medical profession, an organized system of dental
20:24
care, or a level of medical knowledge that implies
20:28
specialized practitioners serving a whole community.
20:31
The evidence does not support such conclusions.
20:35
The drilled teeth are limited in number, found
20:38
in specific burials. and we have no evidence
20:42
that this practice was widespread standardized
20:44
or performed by designated specialists it may
20:49
have been a specific craft tradition perhaps
20:52
associated with particular individuals or lineages
20:55
perhaps performed for particular purposes that
20:59
we do not fully understand it may have had ritual
21:02
or social significance as well as or instead
21:05
of therapeutic intent What we can say with confidence
21:09
is that some people at Mergar possessed a technical
21:11
skill and the conceptual framework to perform
21:14
this intervention, and that this represents a
21:17
remarkable achievement. What we cannot say is
21:21
that Mergar had dentists in anything like the
21:23
modern sense, or that this practice tells us
21:26
about a general system of medical care. The drilled
21:30
teeth are evidence of possibility, not of profession.
21:34
The later history of Mergar... from the Chalcolithic
21:38
periods through to the site's eventual abandonment,
21:42
reinforces the themes of gradual change and regional
21:46
reorganization. Periods III through VII, spanning
21:50
roughly from the 5th to the 3rd millennium BCE,
21:53
show continued occupation and development. Copper
21:57
tools began to appear alongside stone ones. They
22:01
did not replace them but supplemented them for
22:03
certain tasks. Pottery traditions became more
22:07
elaborate, with new forms and perhaps new decorative
22:10
approaches. New areas of the settlement were
22:14
brought into use, suggesting population growth
22:16
or changing social organization. The site expanded
22:21
and changed, but it did not transform into something
22:24
fundamentally different. It remained a farming
22:27
and herding community, with craft production
22:30
and inter -regional connections. adapting to
22:33
changing circumstances across generations the
22:38
people continue to make beads to herd cattle
22:41
and sheep and goats to cultivate wheat and barley
22:45
to build with mud brick and to bury their dead
22:48
with selected objects the changes were real but
22:52
incremental visible in the archaeological record
22:54
as shifts in material culture rather than as
22:57
breaks or revolutions the eventual abandonment
23:01
of mergar sometime around 2600 to 2000 BCE, has
23:07
sometimes been interpreted in dramatic terms.
23:10
It has been described as collapse, as failure,
23:13
as the end of a civilization. The archaeological
23:17
evidence does not support this interpretation
23:19
either. Megar was not abandoned because its inhabitants
23:24
failed or because their way of life became unsustainable.
23:28
It was abandoned. or its population shifted to
23:31
other locations as part of wider changes in regional
23:34
settlement patterns. Other sites in the area,
23:37
other senses of population, became more prominent.
23:41
The Indus Valley civilization was emerging to
23:45
the east, with its urban centers at Harappa and
23:48
Mohenjo -daro. The regional landscape of settlement
23:52
and economy was being reorganized. Megha's role
23:56
in this landscape changed. and eventually the
23:58
site was no longer occupied. This is not collapse.
24:03
It is the normal stuff of historical geography.
24:07
Places rise and fall in importance. Populations
24:10
move. Centres shift. The people who had lived
24:14
at Mergar for more than 4 ,000 years did not
24:17
disappear or fail. They continued elsewhere in
24:21
changed circumstances. The relationship between
24:25
Mergar and the later Indus cities is worth clarifying,
24:29
because it is often misunderstood. Mergar is
24:33
sometimes presented as a direct ancestor of the
24:36
Indus civilization, the first step on an inevitable
24:40
path toward urbanism. This is not what the evidence
24:44
shows. Mergar was one strand in a wider process
24:49
that eventually led to village networks across
24:51
the Indus region and, much later, to the development
24:55
of cities. The farmers of Megha were not on their
24:59
way to building Mohenjo -daro. They were living
25:03
their own lives in their own time with their
25:06
own concerns. The connection between Megha and
25:10
the Indus cities is one of long -term regional
25:13
development, of accumulated knowledge and practice,
25:17
of networks that expanded and intensified over
25:20
millennia. It is not a direct causal chain and
25:24
it is certainly not an inevitable progression.
25:27
If we want an analogy, Mergar's relationship
25:31
to later Indus cities is something like a small
25:34
town's relationship to a later metropolis. It
25:37
is connected through long -term development,
25:40
part of the same regional history but not a direct
25:43
or inevitable precursor. This long perspective
25:47
is what Mergar most fundamentally offers. The
25:51
site preserves no single moment when farming
25:54
began. It records instead generations of experimentation
25:58
with plants, animals, houses, bodies and community.
26:03
People learned which crops grew well on the catchy
26:07
plain, how to store surplus against bad years,
26:10
how to build with local clay, how to make beads
26:14
from imported stone, how to drill teeth. how
26:18
to bury their dead with appropriate objects they
26:22
did this over thousands of years with changes
26:25
that were gradual and cumulative rather than
26:27
sudden and revolutionary they maintained connections
26:31
with regions to the west adopting and adapting
26:34
crops and animals and technologies they developed
26:38
local traditions including the domestication
26:41
of zebra cattle and distinctive practices of
26:43
craft and burial they were not isolated not primitive,
26:48
not on an inevitable path to civilization. They
26:51
were farmers, herders, craftspeople, living in
26:55
a particular place with particular resources
26:58
and particular connections, making their lives
27:01
work across deep time. What remains uncertain
27:04
is also worth acknowledging. The precise chronology
27:09
of Mergar's earliest occupation and its relationship
27:12
to other early sites in the region is still being
27:15
refined. The exact mechanisms by which domesticated
27:19
crops and animals reached Mergar from the west
27:22
are not fully understood. This includes the question
27:26
of whether it happened through migration, exchange,
27:29
or the diffusion of knowledge. The social and
27:34
political organization of Mergar's inhabitants,
27:37
inferred from burial practices and architecture,
27:40
remains debated. The reasons for the site's eventual
27:43
abandonment are not completely clear. environmental
27:47
change, shifting trade routes and regional settlement
27:50
reorganization have all been proposed as contributing
27:54
factors. The full extent of Mergar's connections
27:58
with contemporary sites in Iran, Central Asia
28:01
and the Indus Valley is still being explored.
28:05
And the relationship between Mergar's later phases
28:08
and the emergence of Indus urbanism, while generally
28:12
understood in terms of long -term regional development,
28:15
lacks precise causal links. These uncertainties
28:19
are not failures of research. They are the normal
28:23
condition of archaeological interpretation, and
28:26
acknowledging them honestly is part of what makes
28:29
historical explanation trustworthy. So what did
28:33
the farmers of Mergar begin? They began nothing
28:36
single, war simple. They participated in the
28:40
gradual development of farming, herding, craft
28:43
production, and settled village life in the borderlands
28:46
west of the indus across more than 4 000 years
28:50
of occupation they show us that agriculture in
28:54
south asia was not imported wholesale not invented
28:58
locally in isolation but developed through processes
29:01
of connection and adaptation that links local
29:05
communities with wider networks they show us
29:09
that technological change is uneven that pottery
29:12
can arrive a thousand years after farming That
29:15
dental drilling can exist without a medical profession.
29:18
That a site can be important without being a
29:21
birthplace or a direct ancestor of later civilizations.
29:26
They show us most of all that the deep history
29:30
of human communities is a matter of generations
29:33
experimenting with how to live. With plants,
29:37
with animals, with materials, with each other
29:40
in specific places and specific circumstances.
29:44
accumulating knowledge and practice that eventually,
29:47
and only eventually, made later developments
29:49
possible. The first Indus cities lay thousands
29:53
of years in Megha's future. The farmers who lived
29:57
at the foot of the Bolan Pass did not know this,
30:00
and it was not their purpose. Their purpose was
30:03
to farm, to herd, to make, to bury, to connect,
30:08
to adapt, to continue. and in doing so they left
30:14
a record that helps us understand how human societies
30:17
gradually, laboriously, and without any single
30:21
revolutionary moment, learn to live differently.
