The spread of farming out of the Balkans and into the rest of Europe followed two distinct routes: An initial expansion represented by the Impressa and Cardial traditions, which followed the Northern Mediterranean coastline; and another expansion represented by the LBK (Linearbandkeramik) tradition, which followed the Danube River into Central Europe. Although genomic data now exist from samples representing the second migration, such data have yet to be successfully generated from the initial Mediterranean migration. To address this, we generated the complete genome of a 7,400-year-old Cardial individual (CB13) from Cova Bonica in Vallirana (Barcelona), as well as partial nuclear data from five others excavated from different sites in Spain and Portugal. CB13 clusters with all previously sequenced early European farmers and modern-day Sardinians. Furthermore, our analyses suggest that both Cardial and LBK peoples derived from a common ancient population located in or around the Balkan Peninsula. The Iberian Cardial genome also carries a discernible hunter–gatherer genetic signature that likely was not acquired by admixture with local Iberian foragers. Our results indicate that retrieving ancient genomes from similarly warm Mediterranean environments such as the Near East is technically feasible.
The very earliest LBK sites have loads of pottery sherds with limited evidence of agriculture or stock-breeding. Later LBK sites are characterized by longhouses with rectangular plans, incised pottery, and a blade technology for chipped stone tools. The tools include raw material of high-quality flints including a distinctive "chocolate" flint from southern Poland, Rijkholt flint from the Netherlands and traded obsidian.
Domesticated crops used by the LBK culture include emmer and einkorn wheat, crab apple, peas, lentils, flax, linseed, poppies, and barley. Domestic animals include cattle, sheep and goats, and occasionally a pig or two.
The LBK lived in small villages along streams or waterways characterized by large longhouses, buildings used for keeping livestock, sheltering people and providing workspace. The rectangular longhouses were between 7 and 45 meters long and between 5 and 7 meters wide. They were built of massive timber posts chinked with wattle and daub mortar.
LBK cemeteries are found a short distance away from the villages, and, in general, are marked by single flexed burials accompanied by grave goods. However, mass burials are known at some sites, and some cemeteries are located within communities.
Chronology of the LBK
The earliest LBK sites are found in the Starcevo-Koros culture of the Hungarian plain, around 5700 BC. From there, the early LBK spreads separately east, north and west.
The LBK reached the Rhine and Neckar valleys of Germany about 5500 BC. The people spread into Alsace and the Rhineland by 5300 BC. By the mid-5th millennium BC, La Hoguette Mesolithic hunter-gatherers and LBK immigrants shared the region and, eventually, only LBK was left.
Linearbandkeramik and Violence
There seems to be considerable evidence that relationships between the Mesolithic hunter-gatherers in Europe and the LBK migrants were not entirely peaceful. Evidence for violence exists at many LBK village sites. Massacres of whole villages and portions of villages appear to be in evidence at sites such as Talheim, Schletz-Asparn, Herxheim, and Vaihingen. Mutilated remains suggesting cannibalism have been noted at Eilsleben and Ober-Hogern. The westernmost area appears to have the most evidence for violence, with about one-third of the burials showing evidence of traumatic injuries.

LBK people had an average body height of 166.6 cm for men (ranging from 156.5 to 175.5 cm) and 158 cm for women, considerably shorter than Mesolithic Europeans of the same period. Ancient DNA tests have shown that LBK people had fair skin, brown eyes and dark hair, while Mesolithic Europeans had darker skin, dark hair, but blue eyes. Both groups were lactose intolerant.
