The duration of the Neolithic varies from place to place, its end marked by the introduction of bronze implements: in southeast Europe it is approximately 4,000 years (i.e. 7000 BCE–3000 BCE) while in Northwest Europe it is just under 3,000 years (c. 4500 BCE–1700 BCE).

Regardless of specific chronology, many European Neolithic groups share basic characteristics, such as living in small-scale, family-based communities, subsisting on domesticated plants and animals supplemented with the collection of wild plant foods and with hunting, and producing hand-made pottery, that is, pottery made without the potter's wheel. Polished stone axes lie at the heart of the neolithic (new stone) culture, enabling forest clearance for agriculture and production of wood for dwellings, as well as fuel.
There are also many differences, with some Neolithic communities in southeastern Europe living in heavily fortified settlements of 3,000-4,000 people (e.g., Sesklo in Greece) whereas Neolithic groups in Britain were small (possibly 50-100 people) and highly mobile cattle-herders.[original research?]
The details of the origin, chronology, social organization, subsistence practices and ideology of the peoples of Neolithic Europe are obtained from archaeology, and not historical records, since these people left none. Since the 1970s, population genetics has provided independent data on the population history of Neolithic Europe, including migration events and genetic relationships with peoples in South Asia.[original research?]
A further independent tool, linguistics, has contributed hypothetical reconstructions of early European languages and family trees with estimates of dating of splits, in particular theories on the relationship between speakers of Indo-European languages and Neolithic peoples. Some archaeologists believe that the expansion of Neolithic peoples from southwest Asia into Europe, marking the eclipse of Mesolithic culture, coincided with the introduction of Indo-European speakers,[page needed][page needed] whereas other archaeologists and many linguists believe the Indo-European languages were introduced from the Pontic-Caspian steppe during the succeeding Bronze Age.[page needed]

Archeologists believe that food-producing societies first emerged in the Levantine region of southwest Asia at the close of the last glacial period around 12,000 BCE, and developed into a number of regionally distinctive cultures by the eighth millennium BCE. Remains of food-producing societies in the Aegean have been carbon-dated to around 6500 BCE at Knossos, Franchthi Cave, and a number of mainland sites in Thessaly. Neolithic groups appear soon afterwards in the Balkans and south-central Europe. The Neolithic cultures of southeastern Europe (the Balkans and the Aegean) show some continuity with groups in southwest Asia and Anatolia (e.g., Çatalhöyük).
Current evidence suggests that Neolithic material culture was introduced to Europe via western Anatolia, and that similarities in cultures of North Africa and the Pontic steppes are due to diffusion out of Europe. All Neolithic sites in Europe contain ceramics,[original research?] and contain the plants and animals domesticated in Southwest Asia: einkorn, emmer, barley, lentils, pigs, goats, sheep, and cattle. Genetic data suggest that no independent domestication of animals took place in Neolithic Europe, and that all domesticated animals were originally domesticated in Southwest Asia. The only domesticate not from Southwest Asia was broomcorn millet, domesticated in East Asia. The earliest evidence of cheese-making dates to 5500 BCE in Kujawy, Poland.
Archaeologists seem to[who?][weasel words] agree that the culture of the early Neolithic is relatively homogeneous, compared both to the late Mesolithic and the later Neolithic. The diffusion across Europe, from the Aegean to Britain, took about 2,500 years (6500 BCE - 4000 BCE). The Baltic region was penetrated a bit later, around 3500 BCE, and there was also a delay in settling the Pannonian plain. In general, colonization shows a "saltatory" pattern, as the Neolithic advanced from one patch of fertile alluvial soil to another, bypassing mountainous areas. Analysis of radiocarbon dates show clearly that Mesolithic and Neolithic populations lived side by side for as much as a millennium in many parts of Europe, especially in the Iberian peninsula and along the Atlantic coast.
With some exceptions, population levels rose rapidly at the beginning of the Neolithic until they reached the carrying capacity. This was followed by a population crash of "enormous magnitude" after 5000 BCE, with levels remaining low during the next 1,500 years. Populations began to rise after 3500 BCE, with further dips and rises occurring between 3000 and 2500 BCE but varying in date between regions. A study of twelve European regions found most experienced boom and bust patterns and suggested an "endogenous, not climatic cause."
Genetic studies since the 2010s have identified the genetic contribution of Neolithic farmers to modern European populations,
providing quantitative results relevant to the long-standing "replacement model" vs. "demic diffusion" dispute in archaeology.
The component due to Mesolithic European hunter-gatherers and Neolithic farmers expanding from the Near East were called "Western Hunter-Gatherers" (WHG) and "Early European Farmers" (EEF, also "First European Farmers" FEF), respectively, in the seminal 2014 study which first identified the contribution of three main components to modern European lineages (the third being "Ancient North Eurasians", associated with the later Indo-European expansion).
The EEF component was identified based on the genome of a woman buried c. 7,000 years ago in a Linear Pottery culture grave in Stuttgart, Germany. 
The 2014 study found evidence for miscegenation between WHG and EEF throughout Europe, with the largest contribution of EEF in Mediterranean Europe (especially in Sardinia, Sicily, Malta and among Ashkenazi Jews), and the largest contribution of WHG in Northern Europe and among Basque people.
Since 2014, further studies have refined the picture of interbreeding between EEF and WHG.
In a 2017 analysis of 180 ancient DNA datasets of the Chalcolithic and Neolithic periods from Hungary, Germany and Spain
evidence was found of a prolongued period of interbreeding.
Admixture took place regionally, from local hunter-gatherer populations, so that populations from the three regions (Germany, Iberia and Hungary) were genetically distinguishable at all stages of the Neolithic period, with a gradually increasing ratio of WHG ancestry of farming populations over time.
This suggests that after the initial expansion of early farmers, there were no further long-range migrations substantial enough to homogenize the farming population, and that farming and hunter-gatherer populations existed side by side for many centuries, with ongoing gradual admixture throughout the 5th to 4th millennia BC (rather than a single admixture event on initial contact).
Admixture rates varied geographically; in the late Neolithic, WHG ancestry in farmers in Hungary was at around 10%, in Germany around 25% and in Iberia as high as 50%.
There is no direct evidence of the languages spoken in the Neolithic. Some proponents of paleolinguistics attempt to extend the methods of historical linguistics to the Stone Age, but this has little academic support. Criticising scenarios which envision for the Neolithic only a small number of language families spread over huge areas of Europe (as in modern times), Donald Ringe has argued on general principles of language geography (as concerns "tribal", pre-state societies), and the scant remains of (apparently indigenous) non-Indo-European languages attested in ancient inscriptions, that Neolithic Europe must have been a place of great linguistic diversity, with many language families with no recoverable linguistic links to each other, much like western North America prior to European colonisation.
Discussion of hypothetical languages spoken in the European Neolithic is divided into two topics, Indo-European languages and "Pre-Indo-European" languages.
In the north, a similar scenario to Indo-European is thought to have occurred with Uralic languages expanding in from the east. In particular, while the Sami languages of the indigenous Sami people belong in the Uralic family, they show considerable substrate influence, thought to represent one or more extinct original languages. The Sami are estimated to have adopted a Uralic language less than 2,500 years ago. Some traces of indigenous languages of the Baltic area have been suspected in the Finnic languages as well, but these are much more modest. There are early loanwords from unidentified non-IE languages in other Uralic languages of Europe as well.
