The mobility of the Kurgan culture facilitated its expansion over the entire Pit Grave region, and is attributed to the domestication of the horse
Domestication of the horse

, Pit-Grave and Corded ware horizons (spanning the 4th to 3rd millennia in much of Eastern and Northern Europe).
By the 1980s, it had become clear that this extended "Corded Ware-Battle Axe-Tumulus" burial complex envisaged by Gimbutas needed to be considered separately, under the heading of (3rd millennium) "Kurganization" (spread of "Kurgan elements" beyond the area of the Kurgan culture proper).
Mallory (1986, p. 308) points out that "by the mid-5th millennium BC, we already have very striking cultural similarities from the Dnieper-Donets culture in the west to the Samara culture of the middle Volga ... this is continued in the later Sredny Stog period." The "Yamna culture in all its regional variants" arose later, and may already represent diversification.

The comparison of cultural similarities of these cultures is a question of archaeology independent of hypotheses regarding the Proto-Indo-European language.
The postulate of these 5th millennium "cultural similarities" informed by archaeology are a prerequisite of the "Kurgan model" which identifies the chalcolithic (5th millennium) Pontic-Caspian steppe as the locus of Proto-Indo-European.

Stages of culture and expansion

Gimbutas' original suggestion identifies four successive stages of the Kurgan culture:-
  • Kurgan I, Dnieper/Volga region, earlier half of the 4th millennium BC. Apparently evolving from cultures of the Volga basin, subgroups include the Samara

One difficulty in interpreting the genetic evidence lies in the fact that, according to the mainstream archaeological view, there were likely not one but two separate waves of westbound expansion of foreign cultures throughout Europe. The first wave was associated with the advent of farming; it brought the so-called "Neolithic package" to the Southeastern Europe circa 6500 BCE, and eventually reached the Baltic circa 5000 BCE. It is represented in the archaeological record as the Linear Pottery culture

 (comparative linguistics, University of Leiden) in 1989 proposed a revision of the Kurgan model. He states the main objection which can be raised against Gimbutas' scheme (e.g., 1985: 198) is that it starts from the archaeological evidence and looks for a linguistic interpretation.
Starting from the linguistic evidence and trying to fit the pieces into a coherent whole, he arrives at the following picture: The territory of the Sredny Stog culture

The Sredny Stog culture dates from the 4500-3500 BC. It was situated just north of the Sea of Azov between the Dnieper and the Don...

 in the eastern Ukraine he calls the most convincing candidate for the original Indo-European homeland. The Indo-Europeans who remained after the migrations to the west, east and south (as described by ) became speakers of Balto-Slavic, while the speakers of the other satem languages would have to be assigned to the Pit Grave horizon, and the western Indo-Europeans to the Corded Ware horizon. Returning to the Balts and the Slavs, their ancestors should be correlated to the Middle Dnieper culture. Then, following Mallory (197f) and assuming the origin of this culture to be sought in the Sredny Stog, Yamnaya and Late Tripolye cultures, he proposes the course of these events corresponds with the development of a satem language which was drawn into the western Indo-European sphere of influence.

According to Kortlandt, there seems to be a general tendency to date proto-languages farther back in time than is warranted by the linguistic evidence. However, if Indo-Hittite and Indo-European could be correlated with the beginning and the end of the Sredny Stog culture respectively, he states that the linguistic evidence from the overall Indo-European family does not lead us beyond Gimbutas' secondary homeland, so that the Khvalynsk culture

 in the northern Caucasus cannot be identified with the Indo-Europeans. Any proposal which goes beyond the Sredny Stog culture must start from the possible affinities of Indo-European with other language families. Taken into account a supposed typological similarity of Proto-Indo-European to the North-West Caucasian languages and assuming this similarity can be attributed to areal factors, Kortlandt thinks of Indo-European as a branch of "Uralo-Altaic" which was transformed under the influence of a Caucasian substratum

Such events would be supported by archaeological evidence and locate the earliest formative phase of Pre-Indo-European north of the Caspian Sea in the 7th millennium (cf. Mallory 1989: 192f.), essentially in agreement with Gimbutas’ theory.

Invasionist vs. diffusionist scenarios

It is important to understand that the expansion of proto-Indo-European people in accordance with the Kurgan hypothesis did not constitute the initial peopling of the affected regions. Many of the affected regions were populated by anatomically modern humans for several tens of thousands of years (or at least since the end of the last Ice Age

 circa 12,000 BC).

However, most cultures affected by the Indo-European expansion either were displaced or wiped out, or had to adopt or "hybridize" with the Kurgan culture. This is most evident in the languages.

The migrations were certainly not a sudden, concerted military operation, but the expansion of disconnected tribes and cultures, spanning many generations. To what degree the indigenous cultures were peacefully amalgamated or violently displaced remains a matter of controversy among supporters of the Kurgan hypothesis.

One might at first imagine that the economy of argument involved with the Kurgan solution should oblige us to accept it outright. But critics do exist and their objections can be summarized quite simply – almost all of the arguments for invasion and cultural transformations are far better explained without reference to Kurgan expansions, and most of the evidence so far presented is either totally contradicted by other evidence or is the result of gross misinterpretation of the cultural history of Eastern, Central, and Northern Europe."

Renfrew's linguistic timedepth

While the Kurgan scenario is widely accepted as one of the leading answers to the question of Indo-European origins, it is still a speculative model and not normative. The main alternative suggestion is the theory of Colin Renfrew and Vyacheslav V. Ivanov, postulating an Anatolian Urheimat, that the spread of the Indo-European languages is a result of the spread of agriculture

, 9,000 years as opposed to 6,000, and finds less support among traditional linguists than the Kurgan theory. An argument against the Anatolian Urheimat is that PIE contains words that many interpret as specifically related to cattle-breeding and horse-riding devices invented not earlier than the 5th millennium BC by nomadic tribes in Asian steppes. Notably, many Indo-European languages have similar words meaning axle, for example, Latin axis, Lithuanian ašis, Russian os' , and Sanskrit ákṣa. (In some, a similar root is used for the word armpit: eaxl in Old English, axilla in Latin, and kaksa in Sanskrit.) All these are linked to the PIE root ak's-.

Others dispute those interpretations and the method of 'linguistic palaeontology' on which they are based. It is also difficult to correlate the geographical distribution of the Indo-European branches with the advance of agriculture.

Occurrence of horse riding in Europe

Renfrew (1999: 268) holds that on the European scene mounted warriors appear only as late as the turn of the second-first millennia BC and these could in no case have been "Gimbutas's Kurgan warriors" predating the facts by some 2,000 years. Mallory (1989, p136) enumerates linguistic evidence pointing to PIE period employment of horses in paired draught, something that would not have been possible before the invention of the spoked wheel and chariot, normally dated after about 2500 BC.

According to Krell (1998), Gimbutas' homeland theory is completely incompatible with the linguistic evidence. Krell compiles lists of items of flora, fauna, economy, and technology that archaeology has accounted for in the Kurgan culture and compares it with lists of the same categories as reconstructed by traditional historical-Indo-European linguistics. Krell finds major discrepancies between the two, and underlines the fact that we cannot presume that the reconstructed term for 'horse', for example, referred to the domesticated equid in the protoperiod just because it did in later times. It could originally have referred to a wild equid, a possibility that would "undermine the mainstay of Gimbutas's arguments that the Kurgan culture first domesticated the horse and used this new technology to spread to surrounding areas,"

Pastoralism vs. agriculture

There are several distinct modes of food acquisition in ancient human history. The oldest is the hunter-gatherer mode. In the Neolithic
Neolithic

 era, people first appear to have cultivated existing plants, and then developed domesticated breeds of plants and animals for food production and other utilitarian purposes (e.g. fiber for clothing). Some Neolithic era and subsequent cultures were sedentary and grew crops. Other Neolithic era and subsequent cultures were pastoral, i.e. they herded domesticated animals as a food source. Tensions between the neighboring herder civilizations and farmer civilizations are documented as far back as written history extends to the Sumerians , and continued into the 19th century in much of the world (e.g. the Indian Wars of the 19th century United States).

Nomadic pastoralism

Nomadic pastoralism is a form of agriculture where livestock are herded in order to find fresh pastures on which to graze following an irregular pattern of movement - in contrast with transhumance where seasonal pastures are fix. The herded livestock may include cattle, yaks, sheep, goats,...

 (i.e. nomadic herder civilizations) arose shortly after the development of farming in the Neolithic revolution , possibly through either demic expansion of farming populations with domesticated plants and animals into areas where local environments would not sustain settled farming that abandoned sedentary farming but not domesticated animals, or through cultural diffusion of the tending of domesticated animals to pre-existing hunter-gatherer populations.

The demic diffusion

 model would support an Anatolian origin for Indo-European, as the domesticated species associated with Indo-European societies has its origins in the Near East and Anatolia . In this view, the Kurgans are themselves descendants of Anatolian farmers who would have spoken a proto-Indo-European language and replaced earlier hunter-gatherer populations, prior to serving as a source for many branches of the Indo-European language family.

A cultural diffusion model, in contrast, in which Kurgans speaking their own language acquired domesticated herd animals from Anatolia and domesticated horses, then conquered the non-Indo-European speaking Anatolians, would favor a Kurgan hypothesis.

Kathrin Krell (1998) finds that the terms found in the reconstructed Indo-European language are not compatible with the cultural level of the Kurgans. Krell holds that the Indo-Europeans had agriculture whereas the Kurgan people were "just at a pastoral stage" and hence might not have had sedentary agricultural terms in their language, despite the fact that such terms are part of a Prot-Indo-European core vocabulary.

Krell (1998), "Gimbutas' Kurgans-PIE homeland hypothesis: a linguistic critique", points out that the Proto-Indo-European had an agricultural vocabulary and not merely a pastoral one. As for technology, there are plausible reconstructions suggesting knowledge of navigation, a technology quite atypical of Gimbutas' Kurgan society. Krell concludes that Gimbutas seems to first establish a Kurgan hypothesis, based on purely archaeological observations, and then proceeds to create a picture of the PIE homeland and subsequent dispersal which fits neatly over her archaeological findings. The problem is that in order to do this, she has had to be rather selective in her use of linguistic data, as well as in her interpretation of that data.

Further expansion during the Bronze Age

) are nevertheless subject to some controversy.

Europe

The European Funnelbeaker and Corded Ware cultures have been described as showing intrusive elements linked to Indo-Europeanization, but recent archaeological studies have described them in terms of local continuity, which has led some archaeologists to declare the Kurgan hypothesis "obsolete".
However, it is generally held unrealistic to believe that a proto-historic people can be assigned to any particular group on basis of archaeological material alone.

The Corded Ware culture has always been important in locating Indo-European origins. The German archaeologist Alexander Häusler was an important proponent of archeologists that searched for homeland evidence here. He sharply criticised Gimbutas' concept of 'a' Kurgan culture that mixes several distinct cultures like the pit-grave culture. Häusler's criticism mostly stemmed from a distinctive lack of archeological evidence until 1950 from what was then the East Bloc, from which time on plenty of evidence for Gimbutas's Kurgan hypothesis was discovered for decades. He was unable to link Corded Ware to the Indo-Europeans of the Balkans, Greece or Anatolia, and neither to the Indo-Europeans in Asia. Nevertheless, establishing the correct relationship between the Corded Ware and Pontic-Caspian regions is still considered essential to solving the entire homeland problem.
