Description
The influx of farmers and their domesticated animals from West-Asia into Europe has been well studied. One of the related topics is the genomic turnover occurring in ancient pigs in Europe, where the West-Asian genomic fraction was almost completely replaced indigenous European wild boars several centuries after the introduction of pigs with West-Asian genetic characteristics. This leads us to question and address the complex set of interactions and processes during the spread of early farmers. This issue, particularly in North-Western Europe, has not been fully explored. In this study we generated 12 complete mitochondrial sequences and 12 whole genome sequences (0.02-6x) from The Netherlands (9), England (1) and Ireland (2) ranging from 5500- to 2500 BC. Our resultsshow that there is a Mesolithic European wild boar cluster, which is separate from the European modern wild boar. Our results also suggest a shift through time from the Mesolithic wild genomic fraction towards the European domesticated genomic fraction. Moreover, our study generated multiple whole genomes from a singular site, which could give some insight in how this genomic turnover took place. One interesting find is the occurrence of the black coat color variation, correlated with domestication status and fixed in many domestic breeds, in Schipluiden (3800-3300 BC.) individuals, where three zoo-archaeological categorized domestic pigs show variation in the mutation for black coat color, namely, homozygous derived, heterozygous and homozygous
ancestral. This could potentially increase our understanding of the complex set of interactions of wild boar and domestic pigs in Northwestern Europe.
