[2] 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.
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,[3][page needed][4][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.
Remains of food-producing societies in the Aegean have been carbon-dated to c. 6500 BCE at Knossos, Franchthi Cave, and a number of mainland sites in Thessaly.
The Neolithic cultures of Southeast Europe (including the Aegean) show some continuity with groups in southwest Asia and Anatolia (e.g., Çatalhöyük).
In 2018, an 8,000-year-old ceramic figurine portraying the head of the "Mother Goddess", was found near Uzunovo, Vidin Province in Bulgaria, which pushes back the Neolithic revolution to 7th millennium BC.
and contain the plants and animals domesticated in Southwest Asia: einkorn, emmer, barley, lentils, pigs, goats, sheep, and cattle.
In general, colonization shows a "saltatory" pattern, as the Neolithic advanced from one patch of fertile alluvial soil to another, bypassing mountainous areas.
[12] Investigation of the Neolithic skeletons found in the Talheim Death Pit suggests that prehistoric men from neighboring tribes were prepared to fight and kill each other in order to capture and secure women.
[13] The mass grave at Talheim in southern Germany is one of the earliest known sites in the archaeological record that shows evidence of organised violence in Early Neolithic Europe, among various Linear Pottery culture tribes.
[14] The archaeological site of Herxheim contained the scattered remains of more than 1000 individuals from different, in some cases faraway regions, who died around 5000 BC.
[17] Around this time is the Neolithic decline, when populations collapsed across most of Europe, possibly caused by climatic conditions, plague, or mass migration.
A study of twelve European regions found most experienced boom and bust patterns and suggested an "endogenous, not climatic cause".
A seminal 2014 study 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.
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).
[30] 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%.
The prefix *a- and the suffix *-it- are the most apparent linguistic markers by which a small group of "Agricultural" substrate words - i.e. *arwīt ("pea") or *gait ("goat") - can be isolated from the rest of the Proto-Germanic lexicon.
It is proposed by Šorgo that the Agricultural substrate was characterized by a four-vowel system of */æ/ */ɑ/ */i/ */u/, the presence of pre-nasalized stops, the absence of a semi-vowel */j/, a mobile stress accent, and reduction of unstressed vowels.
