(Note that the study is also by Calo, and note the placement of Sicilians well within the European cluster, near Basques and far away from Africans. When not using blood group studies from the 1970s, Calo is capable of providing accurate information.)

Analisi di 5 microsatelliti nelle tre maggiori isole del Mediterraneo Occidentale

Calo et al. (2001)
Antropo

ABSTRACT: About 360 unrelated individuals from the three largest islands of the Western Mediterranean: Sardinia (Italy), Sicily (Italy) and Corsica (France) were examined. The DNA was amplified by means of PCR and the fragments were separated using a polyacrylamide gel. The microsatellites analysed in the present work are: GABRB3, D15S108, LIPC, D13S115, D13S270. The allele frequencies distribution showed significant differences between the islands. The 5 microsatellites have a high discrimination power (PD) and a high Polymorphic Information Content (PIC). The highest discrimination power was found for GABRB3 and secondarily for D13S115, which also showed the highest values of PIC. The comparison with other populations underlined the populations from the same continent cluster together. Particularly Europeans shows a less genetic heterogeneity than other continents. The results demonstrate that these microsatellites are useful in the study of genetic variability of the human populations and in forensic analysis.

Never seen a study where Asians and Africans cluster closely where as Polynesians and Americans are shown as closely related.

Interesting.

Not particularly.

I didn't think the parent post was worth responding to myself, nonetheless....

Why different population genetic studies present different and apparently conflicting results,

Factors include:

a) what aspects of the human genome you measure.

b) technique for measuring them.

c) what populations you select.

Here is a more recent study which critiques and specifically debunks Erroneous/Dienekes distortions:

Evidence for Gradients of Human Genetic Diversity Within and Among Continents

A recent study in which >350 microsatellites were studied in a global sample of humans showed that they could be grouped according to their continental origin, and by some this has been interpreted as genetic support for “races.”

Here, we investigate how study design can influence such conclusions.

Our results show that when individuals are sampled homogeneously from around the globe, the pattern seen is one of gradients of allele frequencies that extend over the entire world, rather than discrete clusters.

Therefore, there is no reason to assume that major genetic discontinuities exist between different continents or “races.”

The absence of strong continental clustering in the human gene pool is of practical importance.

We see no reason to assume that "races" represent any units of relevance for understanding human genetic history.

Sorry E, as usual, your desperate search for caucaZoid-race leads to another...

Thats doesn't take from the fact that when Arabs were used in another one of Calo et tal's studies, Arab contribution was found to be significant, the study you're using[which is two years older 2003 study] doesn't use Arabs.

A passage from that very study shows how outdated its conclusions are, and how modern research using autosomal polymorphisms is overturning them:

The bottom line is that people are prejudged by their phenotype (how they look) and not their genotype.

Anyone who thinks otherwise come to USA and see how they treat Arabs, Muslims (some more than others) and other sand people???!!
