These are quotes from the study
The Nuragic populations appear to be part of a large and geographically unstructured cluster of modern European populations, thus making it difficult to infer their evolutionary relationships. However, the low levels of genetic diversity, both within and among ancient samples, as opposed to the sharp differences among modern Sardinian samples, support the hypothesis of the expansion of a small group of maternally related individuals,
Translation: That is an outright lie. They hinted at an evolutionary relation ship within the study. They cannot suggest northern Europe because there was no comparable civilization north of Sardinia in Europe. Thus they chose Iberia. Avoiding the geographically closest region ie North Africa, which had a similar civilization. In addition what they are saying is these people later EXPANDED into Europe.
These two sequences find no match in comparisons with 92 Africanfrican samples EITHER (data not given). Six haplotypes are shared between modern and ancient Sardinians, representing 61% of the ancient individuals
Translation: strange choice of words…”EITHER” plus, “data not shown” . Looks like they are trying to prove no connection with Africa. Although the data clearly shows a connection.
All outliers are either populations separated by large geographic distances from the other Europeans ([mainly North Africans and Central Asians), or well-known.
Translation: This is an outright lie. Did they look at a world map and calculated geographic distances? Maybe they thought we wouldn’t. . See notes on Fig 3. the CIRCLE – These European regions are further from Sardinia than North Africa. Estonia, Iceland, Holland, Switzland, etc What is astonishing is they included North African Berbers as Europeans to bring the overall European group closer to the Nuragic. After initially admitting the Sardinians are outliers compared to other Europeans. Man, talk about manipulating data.
In the multidimensional scaling of Fig. 3, Nuragic Sardinians cluster with the majority of the European populations. Given the small sample size, inevitable in ancient DNA studies, it is at present impossible to infer their evolutionary relationships from mtDNA aYnities. Nevertheless, in relation with ancient samples, Nuragic Sardinians appear more related to the Iberians than to the Etruscans, whose position in the graph is eccentric. Three data points are not enough for a robust generalisation. However, one can at least conclude that Sardinians and Iberians show a greater genealogical continuity with the Bronze-Age inhabitants of the same regions than the Tuscans. To better understand the processes leading to these differences it will be necessary to genetically characterise people who lived in those areas between 2,000 years ago and the present time.
Translation: Enough said, according to the authors they were probably Iberians migrants. Although using the same yardstick …they should be classified as North Africans migrants.
