Early European Farmers

Early European Farmers (EEF) were a group of the Anatolian Neolithic Farmers (ANF) who brought agriculture to Europe and Northwest Africa. The Anatolian Neolithic Farmers were an ancestral component, first identified in farmers from Anatolia (also known as Asia Minor) in the Neolithic, and outside of Europe and Northwest Africa. Although the spread of agriculture from the Middle East to Europe has long been recognised through archaeology, until recently it was unknown how this happened, because of lack of human ancient DNA from pre-Neolithic times. Recent (2025) studies have shown that the spread of Neolithic cultures from Anatolia to West Eurasia was a complex phenomenon involving distinct mechanisms, from pure cultural adoption to admixture between migrating farmers and local foragers, to rapid migration. Cultural similarities were not caused by large-scale mobility.

The earliest farmers in Anatolia derived most (80–90%) of their ancestry from the region's local hunter-gatherers, with minor Levantine and Caucasus-related ancestry. The Early European Farmers moved into Europe from Anatolia through Southeast Europe from around 7,000 BC, gradually spread north and westwards, and reached Northwest Africa via the Iberian Peninsula. Genetic studies have confirmed that the later Farmers of Europe generally have also a minor contribution from Western Hunter-Gatherers (WHGs), with significant regional variation. European farmer and hunter-gatherer populations coexisted and traded in some locales, although evidence suggests that the relationship was not always peaceful. Over the course of the next 4,000 years or so, Europe was transformed into agricultural communities, with WHGs being effectively replaced across Europe. During the Chalcolithic and early Bronze Age, people who had Western Steppe Herder (WSH) ancestry moved into Europe and mingled with the EEF population; these WSH, originating from the Yamnaya culture of the Pontic steppe of Eastern Europe, probably spoke Indo-European languages. EEF ancestry is common in modern European and Northwest African populations, with EEF ancestry highest in Southern Europeans, mostly Sardinians and Basque people.

A distinct group of the Anatolian Neolithic Farmers spread into the east of Anatolia, and left a considerable genetic legacy in Iranian Plateau, South Caucasus, Levant (during the Pre-Pottery Neolithic B) and Mesopotamia. They also have a minor role in the ethnogenesis of WSHs of Yamnaya culture.

The ANF ancestry is found in substantial levels in contemporary European, West Asian and North African populations, and is also found in Central, and South Asian populations at lower levels.

Populations of the Anatolian Neolithic derived most of their ancestry from the Anatolian hunter-gatherers (AHG), with a minor geneflow from Iranian/Caucasus and Levantine related sources, suggesting that agriculture was adopted in situ by these hunter-gatherers and not spread by demic diffusion into the region. Ancestors of AHGs and EEFs are believed to have split off from Western Hunter-Gatherers (WHGs) between 45kya to 26kya during the Last Glacial Maximum, and to have split from Caucasus Hunter-Gatherers (CHGs) between 25kya to 14kya.

Genetic studies demonstrate that the introduction of farming to Europe in the 7th millennium BC was associated with a mass migration of people from Northwest Anatolia to Southeast Europe, which resulted in the replacement of almost all (c. 98%) of the local Balkan hunter-gatherer gene pool with ancestry from Anatolian farmers. In the Balkans, the EEFs appear to have divided into two wings, who expanded further west into Europe along the Danube (Linear Pottery culture) or the western Mediterranean (Cardial Ware). Large parts of Northern Europe and Eastern Europe nevertheless remained unsettled by EEFs. During the Middle Neolithic there was a largely male-driven resurgence of WHG ancestry among many EEF-derived communities, leading to increasing frequencies of the hunter-gatherer paternal haplogroups among them.

Around 7,500 years ago, EEFs originating from the Iberian Peninsula migrated into Northwest Africa, bringing farming to the region. They were a key component in the neolithization process of the Maghreb, and intermixed with the local forager communities.

The farmers of the Neolithic British Isles had entered the region through a mass migration c. 4,000 BC. They carried about 80% EEF and 20% WHG ancestry and were found to be closely related to Neolithic peoples of Iberia, which implies that they were descended from agriculturalists who had moved westwards from the Balkans along the Mediterranean coast. The arrival of farming populations led to the almost complete replacement of the native WHGs of the British Isles, who did not experience a genetic resurgence in the succeeding centuries. More than 90% of Britain's Neolithic gene pool was replaced with the arrival of the Bell Beaker people around 2,500 BC, who had approximately 50% WSH ancestry.
