After the introduction of the pottery tradition of La Hoguette and contemporaneous research on Earliest LBK about 10 to 15 years ago, research onthe spread of farming in Central Europe had somewhat stagnated; there were hardly any major advances in factual knowledge, nor could theoretical models be refined. In the last few years, however, an abundance of new data has appeared, partly deriving from botanical and anthropological analyses. Furthermore, newly available results from excavations in European Russia widenour understanding of the manifold and complex changes occurring during the latter 7th and 6th millennium cal BC.

Human expansion in the course of the Neolithic transition in western Eurasia has been one of the major topics in ancient DNA (aDNA) research in the last ten years. Multiple studies have shown that the spread of agriculture and animal husbandry from the Near East across Europe was accompanied by large-scale human expansions. Moreover, changes in subsistence and migration associated with the Neolithic transition have been hypothesized to involve genetic adaptation. Here we present high quality genome-wide data from the Linear Pottery Culture (LBK) site Derenburg Meerenstieg II (DER) (N=32 individuals) in Central Germany. Population genetic analyses show that the DER individuals carried predominantly Anatolian Neolithic-like ancestry and a very limited degree of local hunter-gatherer admixture, similar to other early European farmers. Increasing the LBK cohort size to ∼100 individuals allowed us to perform various frequency- and haplotype-based analyses to investigate signatures of selection associated with changes following the adoption of the Neolithic lifestyle. In addition, we developed a new method called AIMLESS (Admixture-informed Maximum-likelihood Estimation for Selection Scans) that allowed us test for selection signatures in an admixture-aware fashion. Focusing on the intersection of results from these selection scans, we identified various loci associated with immune function (JAK1, HLA-DQB1) and metabolism (LMF1, LEPR, SORBS1), as well as skin color (SLC24A5, CD82) and folate synthesis (MTHFR, NBPF3). Our findings shed light on the evolutionary pressures, such as infectious disease and changing diet, that were faced by the early farmers of Western Eurasia.

Stable isotope signatures of domesticates found on archaeology sites provide information about past human behaviour, such as the evolution and adaptation of husbandry strategies. A dynamic phase in cattle husbandry evolution is during the 6th millennium BCE, where the first cattle herders of central Europe spread rapidly through diverse forested ecological niches, where little is known about pasturing strategies. Here we investigate cattle pasturing and foddering practices using a multi-regional dataset of stable isotope values (δ13C and δ18O; compound-specific stable isotopic analysis δ15N-amino acids and δ13C-dairy fats) measured from cattle bone and teeth, and pottery residues from early farming contexts, and palaeoenvironmental information. Our analysis reveals that farmers practiced different pasturing strategies with the intensive use of forested ecosystems in some areas for both graze and seasonal forage. We propose that the diversity of strategies is related to the adaptation of herding to new environments, which had a positive impact on cattle breeding and milk availability for human consumption.
