2. Figure 1
Maximum-parsimony network of Y-chromosomal biallelic HGs. Circles and squares represent compound haplotypes, or HGs; numbers within them are their arbitrarily assigned names; and arrows or lines between them represent the defining biallelic mutations. The order of occurrence of the 92R7 and DYS257 mutations is not known, because the intermediate HG has not been found; arrows for these polymorphisms are shown adjacent to each other. Where ancestral state is known, arrows point to the derived state. HGs analyzed in this study are indicated by circles; arrows or boxes between them give the nature of the mutation (0, ancestral; 1, derived), and, where appropriate, the restriction enzyme used and the allele cleaved in PCR-RFLP analysis. For HGs not analyzed (squares), information on geographic association is provided by shading. The correspondence of some of these HGs with the haplotype nomenclature of Karafet et al. (1999) and Hammer et al. (2000), whose work is referred to in the text, is as follows: HGs , haplotype 1C; HG 3, haplotype 1D; HG 4, haplotype 3G; HG 7, haplotypes 1A + 2; HG 8, haplotype 5; HGs , haplotype 1U; HG 16, haplotype 1I; HG 21, haplotypes 3A + 4; and HG 9, haplotype “Med.”

3. Figure 2
HG profile of the entire sample set. HG diversity within the complete sample set of 3,616 Y chromosomes, summarized on a simplified version of the network shown in figure 1. The area of each black circle is proportional to the frequency of the HG. Small unblackened circles indicate unobserved HGs (4 and 7). The position of the HG closest to the root (HG 7) is indicated.

Distribution of populations sampled and geographic distribution of Y-chromosomal HG diversity. A, Abbreviated population names. alg = Algerian; arm = Armenian; bas = Basque; bav = Bavarian; bgm = Belgian; brs = Belarusian; bul = Bulgarian; chu = Chuvash; cyp = Cypriot; cze = Czech; dk = Danish; dut = Dutch; ene = East Anglian; enw = Cornish; est = Estonian; fin = Finnish; fra = French; geo = Georgian; ger = German; gk = Greek; got = Gotlander; hun = Hungarian; ice = Icelandic; irl = Irish; ita = Italian; lat = Latvian; lit = Lithuanian; mar = Mari; naf = northern African; nor = Norwegian, oss = Ossetian; pol = Polish; pon = northern Portuguese; pos = southern Portuguese; rom = Romanian; rus = Russian; saa = Saami; sar = Sardinian; scm = Scottish; scw = western Scottish; slk = Slovakian; sln = Slovenian; spa = Spanish; swe = northern Swedish; tur = Turkish; ukr = Ukrainian; yug = Yugoslavian. For a list of linguistic affiliations, see table 1. B–F, HG diversity within each of 47 populations, summarized on a map of Europe. The area of each pie chart is proportional to the sample size, up to a number of ⩾100; sizes are indicated schematically within B. The area of each black or gray sector is proportional to the frequency of the corresponding HG.

5. Figure 4
Spatial autocorrelation analyses. A, Correlogram, calculated using AIDA, for the entire data set. Overall significance is given. B–G, Correlograms, calculated using SAAP, for the six most frequent HGs. The significance of each point is indicated by its symbol, and the overall significance of each correlogram is also given. LDD = long-distance differentiation. In all correlograms, the X-axes show distance classes (km).

6. Figure 5
PC analysis of Y-chromosomal HG diversity. A, PC2 plotted against PC1. B, PC3 plotted against PC2. The percentage of variance explained by each component is given on the axes. Linguistic affiliation for each population is indicated symbolically; the Belgian sample is part Dutch-/part French-speaking and has a hybrid symbol. Abbreviations are as in figure 3.

7. Figure 6
Significant Y-chromosomal genetic barriers within Europe. A, Output from the ORINOCO program. Positions of genetic barriers showing 95% significance after permutation (see the Subjects and Methods section) are indicated by blue through red areas on the black background, with sample sites indicated by stars. A three-dimensional animation of the actual output from the program can be viewed at the Molecular Genetics Laboratory of the McDonald Institute for Archaeological Research Web site. B, Schematic version of the output shown in A, with the positions of barriers indicated as thick lines on Delaunay connections (thin lines) between sample sites.
