During the Bronze Age, Eurasia's genetic, cultural, and linguistic landscape underwent profound changes, driven by migrations and innovations. The Yamnaya culture, originating around 3000 BC in the Pontic-Caspian steppe, played a pivotal role in these transformations. This society, characterized by a nomadic pastoralist lifestyle, introduced significant advancements such as wheeled vehicles, horse domestication, and arsenical bronze metallurgy. The Yamnaya migrations contributed to the spread of Indo-European languages. They reshaped the genetic composition of Europe and Central Asia, giving rise to cultures like the Corded Ware in Europe and the Afanasievo in Siberia.
The Yamnaya genome blended two primary ancestral groups: Eastern Hunter-Gatherers (EHG) and Caucasus Hunter-Gatherers (CHG). These groups introduced paternal haplogroups like R1b and R1a, which are prevalent in modern European populations. Minor genetic contributions also came from Western Hunter-Gatherers and Early European Farmers, reflecting interactions with neighboring populations. By the end of the Bronze Age, Northern Europe exhibited higher Yamnaya ancestry than Southern Europe, highlighting regional variations in admixture.
Cultural transformations during this period were equally significant. The Yamnaya culture's influence on Indo-European language spread was particularly pronounced in Northern and Central Europe. The Corded Ware culture, for example, emerged through a mix of Yamnaya ancestry and Neolithic European traits, becoming a cornerstone of Northern European development. The Sintashta and Andronovo cultures, descendants of Yamnaya, advanced chariot warfare and metallurgy, shaping civilizations across Eurasia. The "Steppe Hypothesis" strongly associates the Yamnaya with the spread of Proto-Indo-European languages, though alternative theories propose earlier origins during the Mesolithic or Neolithic.
Biological changes accompanied these cultural shifts. Traits such as lighter skin pigmentation and lactose tolerance became more prevalent, driven by environmental pressures and social changes. Male-biased migration patterns were evident, reflected in genetic markers and burial practices that underscored patrilocality and emerging social stratification. These migrations brought about not only genetic turnovers but also widespread cultural and technological exchanges.
Despite the Yamnaya's central role, the broader story of Indo-European origins remains complex and debated. Some scholars argue that Proto-Indo-European languages may have emerged earlier than the Yamnaya culture, involving a longer timeline of interaction across Eurasia. Nonetheless, the Bronze Age stands as a transformative era that shaped the genetic, linguistic, and cultural foundations of modern Europe and Central Asia, with the Yamnaya serving as a key catalyst in these changes.

the story of human migration Out of Africa 50,000 years ago outlines human resilience adaptation and exploration
0:15
around 50,000 years ago ancestors of all present-day human populations or
0:20
anatomically modern humans began migrating Out of Africa eventually inhabiting nearly every corner of the
0:26
globe this migration was driven by climatic changes resource scarcity and social and
0:32
technological advancements that enabled humans to explore new areas the journey
0:37
began in East Africa where Homo sapiens had evolved roughly 300,000 years earlier for thousands of years small
0:45
mobile groups lived as hunter gatherers developing skills in tool making communication and cooperation by 50,000
0:53
years ago some groups began to move out of Africa likely through the northeastern route via the Sinai
0:59
Peninsula into the Levant this migration was aided by improved climatic conditions Advanced tools and symbolic
1:06
communication which gave these humans an advantage over species like neanderthals upon entering the Levant
1:13
some groups moved Eastward into Asia While others ventured into Europe these
1:18
migrations were neither linear nor continuous but occurred in waves influenced by environmental changes such
1:25
as glacial Cycles one major wave moved into Europe where they coexisted and
1:31
interbred with neanderthals this interaction left a genetic Legacy that is still present in modern non-african
1:38
populations by 40,000 Homo sapiens had established themselves across much of
1:43
Europe developing distinct cultures and Technologies by this time humans had
1:49
already reached South Asia southeast Asia crossed Open Seas to reach Australia 65 to 50,000 years ago the
1:56
Americas were the last major land masses to be colonized by humans around 20 to 15,000 years ago during the last glacial
2:04
maximum small groups of humans crossed the bearing land bridge from Siberia into Alaska from there they spread
2:11
rapidly Southward along the Pacific coast and through interior corridors they reached the southern tip of South
2:17
America marking the end of a journey that began in Africa tens of thousands of years
2:24
earlier in Europe modern humans began arriving around 50,000 years ago
2:29
coexisting briefly with neanderthals who were already in Decline the harsh Ice
2:35
Age climate forced these early humans to innovate developing more efficient tools and hunting strategies for survival by
2:42
30,000 years ago cultures like the orig nation had emerged known for creating
2:47
tools and weapons from Stone bone and antler later cultures such as the gravan
2:53
and magdalini adapted to changing climates and thrived for thousands of years each characteriz by unique tools
3:01
art and traditions during the Ice Age Europe was a cold dry grassland home to animals
3:08
like mammoths reindeer and bison early humans hunted these animals and gathered plants relying on seasonal migrations of
3:16
reindeer and salmon for sustenance shelters ranged from caves to constructed dwellings near rivers and
3:22
Springs Art and symbolism became increasingly significant with early humans creating beads pendants and cave
3:29
paintings by 30,000 years ago famous sites like Lasco and Altamira display
3:34
detailed depictions of animals often linked to rituals or beliefs Venus figurines suggest shared
3:41
spiritual ideas while magdalenian art from around 20,000 years ago represents
3:47
some of the most advanced symbolic expression of the era as the Ice Age ended and large
3:54
animals disappeared humans adapted to new environments developing innov ative
4:00
ways to record information and express themselves these advancements in art and
4:05
tools reflected their beliefs stories and social connections shaping human
4:11
life beyond mere survival before the Ice Age Europe's
4:17
population consisted of distinct groups such as the vesten cluster in central eastern Europe and the fornal cluster in
4:24
the west early European sites like kostenki in Russia dating back 35 ,000
4:30
years revealed the genetic ancestry of modern Europeans this ancestry found in
4:36
gravettian cultures contributed to the development of tools art and iconic Venus figurines similarly the Goyette
4:44
cave in Belgium provides insights into early Western Europeans who survived the
4:49
coldest ice age periods and later influenced the magdalenian culture during the coldest times humans
4:57
sought refuge in warmer regions like southwestern Europe where the saluton culture thrived after the Ice Age new
5:05
genetic groups like The Villa Bruna ancestry emerged spreading across Europe
5:10
and replacing older populations like the greton these migrations and cultural
5:17
exchanges shaped the genetic and cultural diversity of Europe leading to the populations we recognize today early
5:24
Europeans varied in appearance with Western hunter gatherers having darker skin and lighter eyes while Eastern
5:32
hunter gatherers displayed lighter skin and darker eyes over thousands of years
5:37
migrations environmental shifts and cultural Innovations created the foundations of modern
5:46
Humanity the Mesolithic period which followed the last glacial maximum was a
5:51
time of remarkable human adaptation to the rapidly changing postglacial World in Southwest Asia the natufian
5:59
culture culture played a crucial role in transitioning from hunter gatherer societies to the beginnings of
6:05
Agriculture known for their sedentary way of life the nans established settlements in the Levant and made use
6:12
of resources like wild cereals and small game as the climate warmed they began experimenting with cultivating wild
6:19
cereals laying the foundation for the Agricultural Revolution of the Neolithic
6:26
era the Levant and Anatolia played a central role in the next great transformation of human society the
6:33
introduction of Agriculture as the postglacial climate stabilized around 12 years ago Societies
6:40
in these regions transitioned from a hunter gatherer lifestyle to one centered around farming and permanent
6:49
settlements the natufian people in the Levant began to cultivate wild cereals
6:55
like barley and wheat experimenting with early forms of agriculture
7:00
this transition laid the foundation for the Neolithic agricultural revolution which spread to Anatolia and Beyond in
7:09
Anatolia early farming communities flourished developing sophisticated
7:14
agricultural techniques and domesticating animals like sheep goats and cattle these Innovations spread
7:20
across Europe and Asia transforming human societies and establishing the basis for civilizations but
7:27
fundamentally they all follow a similar path the genetic history of human populations in Europe and Asia has been
7:34
a topic of debate around 45 to 36,000 years ago the ancestors of Western
7:40
eurasians and East Asians split from each other outside Africa later East
7:46
Asians received genetic contributions from an earlier group related to Aboriginal Australians but Europeans did
7:53
not the Western Eurasian ancestors formed a connected population spanning from Europe to Central Asia and
8:00
contributed genes to both modern Europeans and early Americans before
8:05
3000 BC at least three ancestral populations Western hunter gatherers
8:11
early European farmers and ancient North eurasians contributed to the gene pool
8:17
of modern Europeans these groups mixed over Millennia influencing both the cultural
8:23
and genetic evolution of European populations Western hunter gatherers were the dominant population during the
8:30
Mesolithic period Western hunter gatherers individuals had dark skin blue
8:36
or light colored eyes and carried mitochondrial haa groups u5 and U2 they
8:42
lacked modern skin lightning alals and were adapted to pre-agricultural Lifestyles the ydna haa group I was
8:49
common among Western hunter gatherers males with the arrival of Agriculture around 7,000 BC early European farmers
8:57
who descended from Anatolian and lven populations introduced farming practices to Europe these populations carried
9:04
genetic markers such as mitochondrial haplo group T2 and had lighter skin they
9:10
brought alals associated with agricultural adaptation such as the gene for higher amas production indicative of
9:16
a starch-rich diet ancient DNA from this period reveals that the early farmers
9:22
and the hunter gatherers had very different genetic makeups even though they lived close to each other hunter
9:29
gatherers who were part of a group called The pitted wear culture had genes similar to Modern Northern Europeans
9:35
like fins meanwhile Farmers from the funnel Beaker culture had genetic ties
9:40
to Southern Europeans such as Greeks and cypriots this difference in their DNA
9:45
shows that at first these groups didn't mix much possibly because of cultural or
9:51
social barriers over time these groups began to interbreed which eventually
9:56
Blended their genetic traits interestingly ancient farmers in Sweden had DNA similar to Modern sardinians
10:04
while the hunter gatherers were more like today's northern Europeans this suggests that when Farmers first moved
10:10
North they didn't mix much with the locals however in northern Europe there was more genetic mixing later on
10:16
compared to southern Europe where the farmers largely replaced the hunter gatherers for instance sardinians today
10:23
have very little hunter gatherer ancestry while Northern Europeans show much more of this mixing researchers
10:30
found Northern Europeans like the French are genetically between two groups
10:36
sardinians who are related to Europe's first farmers and Native Americans to
10:42
explain this researchers proposed a ghost population called the ancient North eurasians a group that existed
10:48
over 15,000 years ago and no longer has direct descendants today the DNA of a
10:54
24,000 year-old boy from Lake baral in Siberia perfectly matched this ghost
11:00
population and provided a better genetic match than Native Americans ancient
11:05
North Eurasian ancestry was introduced into Europe during the later stages of European prehistory ancient North
11:12
Eurasian populations like the Maloy from Siberia contributed genetic material to
11:18
both hunter gatherers and Farmers this ancestry likely arrived in Europe through migrations from the pontic
11:24
Caspian step where populations carried a mix of Western hunter gatherers ancient North Eurasian and Caucasus Hunter
11:31
gather ancestry this has been further supported by the discovery of a genetic link between the ynah from the Eurasian
11:38
step and later European populations like those in the corded wear culture modern
11:43
Europeans are therefore a mixture of three ancestral groups with significant genetic and cultural transitions
11:49
occurring during the Neolithic and subsequent Bronze Age migrations the Bronze Age starting around 3,000 BC
11:57
brought dramatic cultural changes around 3,00 to 2500 BC the pit grave or
12:03
yamnah culture emerged in Eastern Europe introducing new ideas about family
12:09
property and identity they spread rapidly across regions from Hungary to the euro
12:15
mountains by 2800 BC cultures like the corded wear or battle ax replace the
12:22
remaining Neolithic farming Societies in parts of Europe likely influenced by the pig grave culture the pit grave culture
12:29
from the Eurasian steps marked the beginning of a transformative era these ancient people embarked on vast
12:35
migrations traveling as far as 5,000 km from the alai mountains in the East to
12:41
Southeastern Europe including the Hungarian plain in the west these movements significantly shaped the
12:47
genetic and cultural foundations of future populations across Eurasia the
12:53
yamnah people were early adopters of a nomadic pastoralist lifestyle moving seasonally with their herds of cattle
12:59
sheep and possibly horses this way of life allowed them to utilize vast grassland resources without depleting
13:06
any single area turning the challenging Eurasian step into a sustainable and productive Homeland their Mobility also
13:14
facilitated the spread of early Indo-European languages which would later form the basis of many modern
13:19
European languages yamnaya communities lived in small temporary settlements
13:25
enabling them to adapt to seasonal grazing needs their herd provided food clothing and transport ensuring a stable
13:33
sustainable way of life that supported large-scale migrations and human expansion across the steps the yam NAA
13:40
culture was first identified in 1907 by gorov who excavated burial mounds or
13:46
tumai in Northern Ukraine these Mounds reflected the evolving ferary traditions
13:53
of the Bronze Age steps gorov differentiated between three types of burials pit Graves were early simple
14:01
burial pits covered with Mounds marking the start of the early Bronze Age
14:06
catacomb Graves were middle Bronze Age burials with side niches or tunnels in the grave pits Timber Graves or shria
14:14
were late Bronze Age Graves covered with wooden logs or reads showcasing resource
14:20
adaptability the yamni burials were often marked by Mounds ranging from 12 to 18 m in diameter and around a meter
14:28
in height burials featured contracted supine postures red ochre sprinkling and
14:33
items like clay vessels grinding stones and occasionally bronze daggers their
14:39
grave Goods reflected a blend of local Innovation and influences from cultures like mop the mop culture from the
14:47
mid-4th millennium BC known for its Advanced arsenical bronze Metallurgy and trade networks played a crucial role in
14:54
shaping the yam Naya's technological and economic Foundation innovation like wheel vehicles and B valve casting
15:02
spread through this interaction enabling the yamnaya to enhance Mobility Warfare
15:07
and trade the yamnaya society wasn't monolithic but consisted of diverse Regional groups each with distinct
15:14
burial Customs Pottery Styles and metal work Traditions the North pontic Region
15:19
was influenced by neighboring Balkan cultures with evidence of AR cynical bronze usage and fortified settlements
15:25
like mikova danula region was a cultural crossroads blending local Traditions
15:32
with emerging yamnah elements the Vogal uro region was rich in Copper resources
15:37
favoring pure copper tools over arsenical bronze the Caspian region was nomadic sparsely populated and adapted
15:44
to Aid climates with simpler burial practices the lower danu region reflected a mix of yema and local
15:50
Neolithic Traditions with Western cultural influences genetically yema individuals showed remarkable
15:56
homogeneity likely stemming from a small founding population despite their genetic uniformity their material
16:03
culture varied widely with regional Artisans crafting distinct pottery and metal work the genetic makeup of the yam
16:09
people reflects a blend of distinct ancestral lineages that shaped their unique identity studies of ancient DNA
16:16
have revealed two major ancestral components approximately 50% of the yema
16:22
genome is derived from Eastern hunter gatherers who inhabited the forested steps of Eastern Europe and parts of of
16:29
Siberia during the Mesolithic period this ancestry contributed significantly
16:34
to the yamah paternal lineages especially some dominant cultural foundations including a mobile foraging
16:41
lifestyle that later transitioned into pastoralism the other half of the amnah ancestry stems from Caucasus hunter
16:49
gatherers who lived south of the steps in the Caucasus Mountains this ancestry
16:54
likely came through ad mixture with populations living in the caucuses lower vulgar region the caucuses hunter
17:01
gatherer component introduced mitochondrial Hapa groups such as H and U which were passed down maternally the
17:07
genetic infusion from caucuses hunter gatherers brought a cultural and technological influence including early
17:14
Metallurgy and agricultural practices while the majority of the yamnah genetic
17:19
makeup comes from Eastern hunter gatherers and caucuses hunter gatherers minor influences from Western hunter
17:26
gatherers and Anatolian farmers have been noted in some studies these traces
17:32
suggest interactions with neighboring communities though they were not as significant in shaping the yam's primary
17:39
genetic profile this unique genetic blend underpinned the yam's success as
17:44
pastoral nomads and their ability to rapidly expand across the Eurasian steps
17:50
their mobility and social organization allowed them to dominate vast territories spreading their genetic
17:56
material and possibly early Indo European languages across Europe Central
18:01
Asia and South Asia the yamnah migrations starting around 3100 BC
18:07
likely stem from a combination of factors while they practiced seasonal movements their large-scale expansions
18:14
were influenced by environmental changes resource needs and interactions with
18:19
neighboring cultures the legacy of the Yia people lives on not just in their burial mounds scattered across the steps
18:27
but in their profound impact on the genetic linguistic and cultural heritage of Europe and beyond their Innovations
18:34
in mobility and Metallurgy laid the groundwork for the complex societies that would follow in the Bronze Age
18:40
world the ynah culture represents a pivotal chapter in the history of the eurasion steps these early herders
18:47
brought significant changes to human societies blending Mobility Innovation
18:52
and cultural exchange to create a way of life that profoundly influenced the regions they touched unlike like earlier
18:59
herders the yumnah may have been the first true Nomads of the Eurasian steps
19:05
by focusing on cattle sheep and horses they began utilizing untapped grasslands
19:10
transforming these vast Landscapes into sustainable grazing grounds this Mobility required Advanced social
19:17
structures to manage land coordinate group movements and maintain clanned
19:23
connections it also demanded practical skills like horse handling and wagon maintenance which enabled them to travel
19:29
great distances the yamnaya lifestyle was shaped by its environment poor soils
19:35
and limited rainfall made farming impractical so they relied on livestock for survival their diet rich in animal
19:42
products is revealed through Modern scientific techniques such as analyzing Isotopes in bones and studying Dairy
19:49
proteins in Dental plaque evidence from Yuma Graves shows a focus on sheep and goats which were easier to move than
19:56
larger cattle and the absence of grains confirms they did not practice agriculture the discovery of HSE milk
20:02
proteins in their remains even marks the earliest evidence of horse milking the invention of the wagon around 3500 BC
20:09
coupled with horseback riding revolutionized their Mobility wagons powered by oxen carried heavy loads like
20:16
tents and food while horseback riding allowed for Swift travel and efficient herd management some researchers believe
20:24
wagons symbolized status but they undoubtedly enabled herders to access new pastures and resources the
20:31
domestication of horses played a crucial role in their success evidence from sites like bow tie in Northern
20:37
Kazakhstan shows that horse domestication began as early as 3500 BC
20:42
over time the yam NAA Incorporated horses into their culture using them for riding milking and rituals one grave
20:50
even contained the skulls of 40 horses highlighting their cultural significance
20:56
The Yuma are best known for their burial mounds or tumuli marked the steps with visible
21:02
symbols of their presence these tumuli constructed from stacked Turf were often
21:07
placed far from Rivers emphasizing their use of open grasslands burials reflected a weak but
21:15
noticeable hierarchy with some individuals interred with valuable Goods such as wagons or weapons hinting at
21:23
emerging social inequality as the yamnaya migrated Westward into regions like the B and carpathians they brought
21:30
their Customs including burial practices ochre use and contracted burials over
21:37
time these practices blended with local Traditions creating a cultural Fusion rather than outright Conquest for
21:44
example yamnaya burial mounds in Bulgaria began incorporating local Pottery showing gradual integration the
21:52
spread of yamnaya culture wasn't a one-way Journey cultural exchanges flowed back to their Homeland and
21:58
enriching the steps with influences from the Balkans and carpathians this pendulum migration
22:05
facilitated the development of hybrid cultures such as the corded wear culture which merged yamnah Traditions with
22:12
local European elements the Yia migration left a lasting genetic and cultural imprint on Europe but it was a
22:19
gradual process their influence can be seen in the diets burial customs and
22:24
social structures of later European societies by introducing wield transport
22:30
Advanced pastoralism and the use of horses they set the stage for future innovations that would shaped the
22:36
ancient world in Asia during the early Bronze Age most regions were still dominated by hunter gatherers except for
22:43
the AL mountains where the apano culture closely resembled the yamnaya by 2000 BC
22:50
the sintashta culture arose in the Euro region the cinta culture from 21 to 1800
22:56
BC was a bronze archaeological culture that thrived in the Eurasian step uh
23:02
particularly in modern day Russia and Northern Kazakhstan it is renowned for its Advanced Metallurgy the earliest
23:09
known use of War chariots and its role in shaping the Indo-European language family especially its eastern branches
23:17
sentasha settlements were fortified with walls and Moes reflecting a highly organized Society their tomely burials
23:24
contain grave Goods such as Weapons ornaments and chariots indicating a
23:29
stratified social structure the sintashta culture evolved from several earlier step cultures with the Yuma
23:36
culture being a significant predecessor the pava culture between 27 to 2100 BC
23:43
which was a direct descendant of Yuma introduced Innovations in Metallurgy and
23:49
burial Customs that influenced sintashta the abashev culture between 25 to 1900
23:55
BC located in the forest step regions and played a crucial intermediary role
24:01
contributing Advanced metallurgical skills and evidence of social stratification to sasa's development the
24:08
sintashta cultures Legacy continued through its successor the Ander noo culture from 2000 to 900 BC which
24:16
expanded its influence across a vast region of the Eurasian step this cultural Continuum shaped the
24:22
development of indo-iranian societies and contributed to the cultural and technological advance ances of later
24:29
step cultures the saska culture remains a critical Link in understanding the early dynamics of Indo-European
24:35
societies and the evolution of Bronze Age civilizations around 1500 BC the
24:41
andronova culture gave way to others like the me skaya and karasuk however there's an ongoing
24:48
debate about whether these major cultural changes were driven by migrations or the exchange of ideas
24:54
among settled groups additionally it's uncertain if the spread of Indo-European
25:00
languages is directly linked to these events or if it happened earlier during
25:05
the Bronze Age Europe was genetically diverse while the populations in Northern and Central Europe were a mix
25:10
of earlier hunter gatherers and Neolithic Farmers they started to include Caucasian genetic material at
25:17
the beginning of the Bronze Age this genetic shift matches the spread of the yumia culture from the ponac Caspian
25:24
step into Europe this mixture created the people of cultures like like the corded wear these cultures show
25:31
different levels of genetic connection to the yamnaya with the highest in the corded wear culture intermediate in
25:38
central European Bell beakers and lowest in Hungary studies show that the Caucasian
25:43
genetic component found in Bronze Age Europe likely came from the step not
25:49
from the southern Caucasus this is evidenced by ancient DNA from ancient
25:54
individuals across Europe covering a period from the Mesolithic to the Iron Age which suggests that populations from
26:01
the Eurasian step migrated into Europe during this time the Y chromosome HAPO
26:08
groups which are common in modern Europeans spread across Europe after
26:13
3000 BC over time the gene pools of early European Farmers originally
26:19
distinct from hunter gatherers mixed significantly especially with the arrival of Step
26:25
populations the ancient DNA highlights how the emergence of the corded wear culture was not just a cultural exchange
26:33
but the result of migration the step populations brought new genetic traits that reshaped Europe's genetic makeup in
26:41
southern Europe such as in Italy the copper AG rodello culture didn't show this caucasian genetic influence
26:47
indicating it was either unaffected by the amnah or developed before their migration into the region the genetic
26:54
link between the corded Weare and cinta cultures suggests they share similar
26:59
ancestry which challenges earlier ideas that the sintashta came from Asia or the
27:04
Middle East the presence of Neolithic farmer genes in both cultures supports
27:10
the idea that the cacha may have come from a migration of corded Weare people or a common earlier step population the
27:18
Bronze Age in Asia was marked by Major migrations and population changes the
27:23
aphan Evo culture which appeared in the alion region during the early Bronze Age
27:28
is genetically very similar to the ynah confirming that the ynah people expanded Eastward across the step in addition to
27:36
their migration West into Europe This created a genetic link that stretched from Siberia to Scandinavia in Central
27:43
Asia the andronovo culture which emerged later in the Bronze Age was closely
27:49
related to the sintashta culture but distinct from both the yamnaya and afano
27:56
cultures the andronovo culture can be seen as an extension of the sintashta
28:02
gene pool towards the end of the Bronze Age the andronovo culture was replaced
28:07
by the karasuk mov skaya and Iron Age cultures these later cultures were more
28:13
ethnically diverse showing genetic mixing with East Asians but still maintained a higher level of West
28:19
Eurasian ancestry compared to present day populations in the region interestingly the Bronze Age okano
28:26
culture from the Diana alai region is genetically related to present-day Native Americans supporting earlier
28:34
findings that the upper Paleolithic Malta hunter gatherers who lived near Lake Bal contributed genetic material to
28:41
Native American populations the spread of the Indo-European languages is believed to
28:48
have occurred through migration and social dominance with the archaeological records showing similar cultural traits
28:54
across Western Eurasia during the 3D millennium BC the genetic findings align
28:59
with the idea that the spread of Yuma people from the pontic Caspian step to Northern Europe and Central Asia played
29:06
a key role in this expansion genetic analysis including
29:14
autosomal mitochondrial DNA and Y chromosome data shows that by the end of
29:19
the Bronze Age the genetic structure of Europe and Central Asia closely resembled the present-day Eurasian
29:25
genetic landscape this suggests that much of the genetic makeup of modern eurasians was shaped during this period
29:32
through complex patterns of migration mixing and population
29:38
replacement modern Eurasian populations are genetically closer to bronze age groups than to earlier Mesolithic or
29:45
Neolithic populations however Southern European populations like sardinians and
29:50
Sicilians have the strongest genetic links to Neolithic Farmers the Bronze Age Europe saw saw
29:58
genetic changes over a period of about 3,000 years particularly in traits such as skin pigmentation and eye
30:06
color the Alo for lighter skin in Europeans increased rapidly in frequency
30:11
eventually reaching fixation between the Mesolithic and Bronze Age in Europe This suggests a strong selection for lighter
30:18
skin but what if it's [Music] conflicting the gene for blue eyes was
30:24
already present in Mesolithic Europeans and was more were common in Bronze Age populations but it was absent in the
30:32
yumnah culture of the pontic Caspian step where brown eyes were more
30:38
prevalent the gene for lactose tolerance was surprisingly rare in the Bronze Age
30:43
compared to modern-day Northern Europeans the highest frequency of
30:48
lactose tolerance was found in the corded wear in Scandinavian Bronze Age
30:54
cultures but the Yuma step cultures showed the highest frequency of the derived alil suggesting that lactose
31:02
tolerance may have originated in the step the spread of Indo-European
31:09
languages and major cultural changes during the Bronze Age were driven by migrations but of a different nature
31:15
than previously thought the yamnaya and afano cultures spread Eastward into
31:20
Central Asia and the alai cyan region with limited local mixing in contrast
31:26
the corded wear culture in Europe resulted from ad mixture with local Neolithic populations the sintashta
31:33
culture near the eurals likely represents an Eastward migration into
31:38
Asia and eventually evolved into the andronovo culture which was replaced by
31:43
East Asian populations over [Music] time these migrations during the early
31:50
Bronze Age likely contributed to the spread of Indo-European languages the aphan Evo culture around 3,000 BC may
31:58
have spoken an Indo-European language which could have spread Southward to the tarim Basin in China explaining the
32:04
early presence of indoan languages like tocharian however we caution that the
32:10
relationships between cultural shifts migrations and language spread must be studied in detail for each
32:18
case one interesting aspect of these early migrations is their gendered nature studies suggests males and
32:26
females experience different migration patterns due to cultural norms around inheritance residence patterns and
32:33
social hierarchy ethnographic evidence shows
32:38
that farming societies tend to have higher rates of Patrol locality where males remain in or near their birthplace
32:46
while females move the Neolithic migration which brought farming into
32:51
Europe suggests that both males and females may have migrated to Europe with
32:57
light male dominance later migrations from the pontic Caspian step culture are also
33:05
believed to have been male biased this hypothesis is supported by the rapid spread of Y chromosomal Hypes like r1a
33:12
and r1b which became common in Central Europe around 2500 BC archaeological
33:18
evidence including male-dominated burial practices and the importance of male Associated Technologies like
33:24
horse-driven wagons reinforces the notion that these migrations were
33:30
male-dominated the genetic data supports the idea that while the Neolithic migration involved both sexes the
33:37
migration from the pontic Caspian step was overwhelmingly male-biased shaping
33:42
the demographic structure of Europe in significant ways during the Neolithic and Bronze Age
33:49
periods there are also Regional differences in the presence of yamnaya ancestry in Europe Northern Europe has
33:56
higher levels of yamnaya ancestry while southern Europe has lower levels All European populations can be modeled
34:03
as a mixture of Western hunter gatherers early Neolithic farmers and yamnaya
34:09
although some outlier populations Show additional mixing with populations from Siberia and the near East while ancient
34:16
DNA cannot directly confirm the languages spoken by pre-literate populations it offers insights into
34:23
migratory processes that align with theories about Indo European
34:29
dispersals genetic research challenges the Anatolian hypothesis which suggests
34:35
that Indo European languages spread from Anatolia with the First Farmers and supports the step hypothesis which
34:42
posits that early Indo European languages spread from pastoralists of the Eurasian step particularly through
34:48
the yamnaya and corded wear cultures this theory is backed by the massive genetic turnover in Central Europe where
34:55
yamnaya migrants replaced about 75% of the local
35:01
ancestry this Theory posits that the yamnaya were associated with the proto-indo-european language with the
35:07
spread of their culture influencing various later linguistic groups such as Greek Germanic Slavic and Celtic which
35:15
are thought to have originated from the corded Weare cultures in northern Europe however this view has been met with
35:22
criticisms and alternative hypotheses some Scholars argue that not
35:28
all Indo-European languages Trace back to the yamnaya suggesting that the yamnaya may represent the origin of only
35:35
some of the Indo-European subfamilies such as Indo Iranian rather than the
35:41
proto-indo-european language itself but this would imply that the
35:46
spread of Indo-European languages across northern Europe cannot be directly attributed to the yamnaya migration the
35:54
challenge lies in the differences between the yamaya culture and the the corded wear culture which are seen as
36:00
distinct in their burial practices material culture and social
36:06
structures the yumnah people are known for their Barrow burials which include primary and secondary burials red ocher
36:13
covered Graves and distinctive Ceramics in contrast the corded wear culture
36:19
though geographically overlapping with the yam NAIA had different burial Customs pottery and a preference for
36:25
stone battle axes these differences suggest that while there might have been some cultural
36:31
exchange the two cultures were distinct and the yamaya did not directly influence the corded Weare cultures to
36:39
the extent that some genetic studies suggest furthermore the timing of the
36:45
breakup of the proto-indo-european language based on glotoch chronology and cladistics ranges from the 7th to 5ifth
36:52
millennium BCE glottochronology is a method in linguistics that estimates the
36:58
time of Divergence between two languages or dialects this is done by analyzing
37:04
the core vocabulary shared by languages and calculating how much of it has remained unchanged over time this
37:10
suggests a long and Complex Evolution of the Indo-European languages making it
37:16
unlikely that a single migration event such as that of the yamnaya could explain the linguistic diversification
37:23
across Europe therefore while the step migration theory is influential it
37:30
remains a matter of ongoing debate and the relationship between genetics language and culture is more complex
37:38
than initially thought the development of Indo European
37:44
languages and cultures likely involved multiple waves of migration and interactions between different groups
37:50
over Millennia making it difficult to pinpoint a single origin for the language family
37:58
recent studies challenged the notion that the yamnah people directly spoke the Proto indoeuropean language
38:04
radiocarbon dating has shown that the amnah culture persisted until around 2600 BC with its derivative cultures
38:12
like the pavka and catacomb cultures emerging around the same time this
38:18
leaves a significant temporal Gap approximately 2.5 Millennia between the
38:23
decline of the yumnah culture this Gap cast doubt on the idea
38:28
that the yah spoke proto-indo-european as the breakup of a language typically precedes the
38:35
disintegration of the associated culture the corded wear cultures which
38:40
arose in the early 3rd millennium BC seem to be contemporaneous with the
38:46
yumnah culture interestingly genetic studies
38:51
reveal that the step genetic influence in the corded wear cultures is most pronounced in northern Europe gradually
38:59
decreasing towards the south in regions like Hungary where the western edge of
39:04
the yamia culture existed this suggests that the genetic
39:10
contributions to both the yamnah and corded Weare cultures may have originated from a shared northern
39:16
European Source not necessarily from the Southeastern
39:22
steps Additionally the Ukrainian archaeologist znc propos osed that the
39:28
proto-indo-european language might have originated much earlier during the late Mesolithic to early Neolithic 6th to
39:34
5ifth Millennia BC potentially in regions from the Baltic to the
39:41
Neer his work based on archaeological and anthropological evidence aligns with glotoch chronological studies this
39:48
shifts the time frame for the origins of Proto induran back by several Millennia
39:54
further complicating the step migration hypothesis
39:59
in conclusion the amnah culture likely did not speak proto-indo-european and the spread of
40:05
Indo-European languages is more complex than previously thought with the origins of the language and its dispersal
40:12
potentially tracing back to an earlier period in different regions of Europe
