“…In stark contrast, in Sardinia, we observed remarkable constancy of WHG ancestry close to 20% throughout our sampling periods, well into the second millennium BCE. This reflects the continuity of Sardinia through this time period and is consistent with a model of a low density or even absence of local Mesolithic hunter-gatherers at the time of arrival of EEF individuals (L ugliè , 2018). However, we can not rule out a model with an initial pulse of local admixture.…”

“…This new evidence points towards Neolithic Sardinian individuals descending principally from mainland Neolithic populations. This hypothesis is also consistent with a signal of population turnover associated with the Neolithic transition observed in Sardinian ancient mtDNA (M odi et al , 2017), and with a gap in the Sardinian archaeological record before its Neolithic transition (L ugliè , 2018).…”

“…The oldest known human remains on Sardinia have been dated to be ∼ 20, 000 years old (M elis , 2002), implying that humans first reached the island during the Paleolithic Age. Archaeological evidence suggests that the island was not densely populated in the Mesolithic, with only irregular and episodic settlements, mostly concentrated near the coast (L ugliè , 2018). The archaeological record shows that a population expansion coincided with a Neolithic transition in the sixth millennium BCE (F rancalacci et al , 2013).…”

34Recent ancient DNA studies of western Eurasia have revealed a dynamic history of admixture, 35 with evidence for major migrations during the Neolithic and Bronze Age. The population of the 36 Mediterranean island of Sardinia has been notable in these studies -Neolithic individuals from 37 mainland Europe cluster more closely with Sardinian individuals than with all other present-day 38 Europeans. The current model to explain this result is that Sardinia received an initial influx 39 of Neolithic ancestry and then remained relatively isolated from expansions in the later Ne-40 olithic and Bronze Age that took place in continental Europe. To test this model, we generated 41 genome-wide capture data (approximately 1.2 million variants) for 43 ancient Sardinian individu-42 als spanning the Neolithic through the Bronze Age, including individuals from Sardinia's Nuragic 43 culture, which is known for the construction of numerous large stone towers throughout the is-44 land. We analyze these new samples in the context of previously generated genome-wide ancient 45 DNA data from 972 ancient individuals across western Eurasia and whole-genome sequence data 46 from approximately 1,500 modern individuals from Sardinia. The ancient Sardinian individuals 47 show a strong affinity to western Mediterranean Neolithic populations and we infer a high degree 48of genetic continuity on the island from the Neolithic (around fifth millennium BCE) through 49 the Nuragic period (second millennium BCE). In particular, during the Bronze Age in Sardinia, 50 we do not find significant levels of the "Steppe" ancestry that was spreading in many other parts 51 of Europe at that time. We also characterize subsequent genetic influx between the Nuragic 52 period and the present. We detect novel, modest signals of admixture between 1,000 BCE and 53 present-day, from ancestry sources in the eastern and northern Mediterranean. Within Sardinia, 54 we confirm that populations from the more geographically isolated mountainous provinces have 55 experienced elevated levels of genetic drift and that northern and southwestern regions of the 56 island received more gene flow from outside Sardinia. Overall, our genetic analysis sheds new 57 light on the origin of Neolithic settlement on Sardinia, reinforces models of genetic continuity on 58 the island, and provides enhanced power to detect post-Bronze-Age gene flow. Together, these 59 findings offer a refined demographic model for future medical genetic studies in Sardinia.60

The permanent human presence in Corsica is attested in the Neolithic period since the 6 th millennium BC and possible interactions with mainland and other islands are suggested by the wider appearance of non-local lithic resources and similar ceramic traditions over a larger Western Mediterranean region 7 .…”

Despite being the fourth largest island in the Mediterranean basin, the genetic variation of Corsica has not been explored as exhaustively as Sardinia, which is situated only 11 km South. However, it is likely that the populations of the two islands shared, at least in part, similar demographic histories. Moreover, the relative small size of the Corsica may have caused genetic isolation, which, in turn, might be relevant under medical and translational perspectives. Here we analysed genome wide data of 16 Corsicans, and integrated with newly (33 individuals) and previously generated samples from West Eurasia and North Africa. Allele frequency, haplotype-based, and ancient genome analyses suggest that although Sardinia and Corsica may have witnessed similar isolation and migration events, the latter is genetically closer to populations from continental Europe, such as Northern and Central Italians.

“…The oldest known human remains on Sardinia date to~20,000 years ago 15 . Archeological evidence suggests Sardinia was not densely populated in the Mesolithic, and experienced a population expansion coinciding with the Neolithic transition in the sixth millennium BCE 16 . Around this time, early Neolithic pottery assemblages were spreading throughout the western Mediterranean, including Sardinia, in particular vessels decorated with Cardium shell impressions (variably described as Impressed Ware, Cardial Ware, Cardial Impressed Ware) 17 , with radiocarbon dates indicating a rapid westward maritime expansion around 5500 BCE 18 .…”

Genetic history from the Middle Neolithic to present on the Mediterranean island of Sardinia

The island of Sardinia has been of particular interest to geneticists for decades. The current model for Sardinia's genetic history describes the island as harboring a founder population that was established largely from the Neolithic peoples of southern Europe and remained isolated from later Bronze Age expansions on the mainland. To evaluate this model, we generate genome-wide ancient DNA data for 70 individuals from 21 Sardinian archaeological sites spanning the Middle Neolithic through the Medieval period. The earliest individuals show a strong affinity to western Mediterranean Neolithic populations, followed by an extended period of genetic continuity on the island through the Nuragic period (second millennium BCE). Beginning with individuals from Phoenician/Punic sites (first millennium BCE), we observe spatially-varying signals of admixture with sources principally from the eastern and northern Mediterranean. Overall, our analysis sheds light on the genetic history of Sardinia, revealing how relationships to mainland populations shifted over time.
