We sequenced the complete genome of the DNA contained in the gourd at low coverage (∼2.5×) with coding sequences enriched at a higher ∼7.3× coverage. We found that the ancestry of the gourd's genome does not seem compatible with Louis XVI's known ancestry. From a functional perspective, we did not find an excess of alleles contributing to height despite being described as the tallest person in Court. In addition, the eye colour prediction supported brown eyes, while Louis XVI had blue eyes. This is the first draft genome generated from a person who lived in a recent historical period; however, our results suggest that this sample may not correspond to the alleged king. ; This work is supported by FEDER and Spanish Government grants BFU2012-38236 and the Spanish Multiple Sclerosis Netowrk (REEM) of the Instituto de Salud Carlos III (RD12/0032/0011) to A.N., BFU2011-28549 and ERC Starting Grant (260372) to T.M.-B. and BFU2012-34157 to C.L.-F. and S.C., and a predoctoral fellowship from the Basque Government (DEUI) to I.O. ; Peer Reviewed
Ancient genomic sequences have started to reveal the origin and the demographic impact of farmers from the Neolithic period spreading into Europe. The adoption of farming, stock breeding and sedentary societies during the Neolithic may have resulted in adaptive changes in genes associated with immunity and diet. However, the limited data available from earlier hunter-gatherers preclude an understanding of the selective processes associated with this crucial transition to agriculture in recent human evolution. Here we sequence an approximately 7,000-year-old Mesolithic skeleton discovered at the La Braña-Arintero site in León, Spain, to retrieve a complete pre-agricultural European human genome. Analysis of this genome in the context of other ancient samples suggests the existence of a common ancient genomic signature across western and central Eurasia from the Upper Paleolithic to the Mesolithic. The La Braña individual carries ancestral alleles in several skin pigmentation genes, suggesting that the light skin of modern Europeans was not yet ubiquitous in Mesolithic times. Moreover, we provide evidence that a significant number of derived, putatively adaptive variants associated with pathogen resistance in modern Europeans were already present in this hunter-gatherer. ; The POPRES data were obtained from dbGaP (accession number # 2038).
