Parallelism between the frequencies of differently oriented whorls and other pattern types in Basque population

In a sample from the Biscaian Basque population, we studied the incidence of pattern types in fingers and the parallelism between the frequencies for the orientations of whorls (Wr, Ws, Wu) and the other pattern types (Lr, A, Lu). We reaffirm the importance of clarifying pattern types according to their orientation, which is of general use in the case of loops but less easily applied to whorls.     

Palmar ridge systems

A six — or seven — (fingers) «sites» system with sequential invading of interdigital ridge bundles agrees very well with actual data from literature. The palmridges of the left hand lag one «period» behind those of the right hands. Main line formulas and the regularities in their frequencies are to a large extent predictable and can be understood from the 7- «sites» model proposed in this publication.     

Genetic and socio-cultural differentiation in the aborigines of Arnhem Land, Australia

Four tribes of Arnhem Land were surveyed for dermatoglyphics; based on pattern intensity indices, total ridge-counts, and a distance statistic combining the two, it was shown that the tribes can be arranged into western (Tiwi, Gunwinggu) and eastern (“Murngin” and Andilyaugwa) groups. This substantiates observations made on Arnhem Land by linguists and social anthropologists. From a survey of allele frequency traits of blood factors and P.T.C. tasting, distance statistics were computed between the four tribes. These confirmed the relative isolation of the extreme Arnhem Land tribes. Distance statistics were also computed between the four tribes and two Central Australian tribes, the Aranda and Wailbri. The Aranda and “Murngin” were relatively close together agreeing with theories that the Aranda are derived from a not too remote southwards migration from north Arnhem Land, as supported by linguistic data. Correlations between the biological, geographical and linguistic distances were positive, and generally agreed with the expectation that socio-cultural and linguistic barriers are important in regulating gene flow between populations. This study emphasizes the need to consider biological distances in association with ecological and socio-cultural factors.     

Dermatoglyphics in the Bushmen

Analysis of the dermatoglyphics of a sample of Kung Bushmen living in the Kalahari of north-east Namibia is presented, and the results are compared with those of other Bushmen studies. A high frequency of arches, a low ridge count, and high frequencies of pattern reduction forms, appear characteristic.     

Dermatoglyphic variation in the human populations of the North Pennine Dales,North England. I. Sex differences,bilateral asymmetry,digital diversity and regional variation

The North Pennine Dales are sparsely populated and deeply indented valleys in the central uplands of northern England. Travel to service centres on the surrounding low lying terrain, especially to the industrial conurbations, is channelled by way of the dale mouths. Communication over the dale heads is difficult and is thus much dictated by topography and by the orientation of each dale. This paper represents the first of two reports on the finger and palmar dermatoglyphics of the populations. Basic data are presented on sex differences, bilateral asymmetry and digital diversity. Univariate statistical tests have been carried out between the dales' populations for several stages based on the selection of individuals by ancestry. Several significant differences occur but no more than would be expected by chance. Distinct spatial patterning does recur for several variables, but on the available data a univariate approach has been unsuccessful in determining the nature and causes of overall population interrelationships.     

裕固族皮纹学初步研究

本文研究了甘肃裕固族青少年儿童346人的皮纹学特征,报道了斗、箕、弓各型指纹的频率,指纹指数,总指嵴数,a-b嵴数,通关手出现率,掌纹真实花样等8项皮纹学参数和主线止区的分布比例。并作了性别、手别、族别及人种间的比较。结果表明,裕固族既具有蒙古人种的皮纹特征,也有一些白种人的皮纹特点,这可能暗示着裕固族有白种人的血统。     

Simian crease incidence and the correlation with thenar and hypothenar pattern types in Swedish patients with trisomy 21 (Down's syndrome)

In the present study the frequency of the simian crease among 57 Down patients is compared to the corresponding figures of related and unrelated individuals. A study of the correlation with the dermatoglyphic patterns of the thenar and hypothenar areas is presented, the palm print classification being carried out according to a Swedish method.

藏猴（Macaca thibetana）皮纹的研究

四川省峨眉山的18只(♀:10;♂:8)及凉山雷波县的19只(♀:7;♂:12)藏猴手足面上皮纹显示,该种的皮纹与其他猕猴属动物基本相同:其指趾端上的花纹几乎全是原始花纹;掌面上,大小鱼际主要为箕形和开放形花纹,指间Ⅰ—Ⅳ区主要为斗形纹;跖面上,大小鱼际及趾间Ⅰ—Ⅱ区则主要是箕形纹,趾间Ⅲ—Ⅳ区主要是斗形纹。左右端指间Ⅱ—Ⅳ区及趾间Ⅲ—Ⅳ区花纹分布有一定差异。性别之间在指间Ⅰ区有显著差异。两地猴则在掌面大鱼际、指及趾间Ⅰ区具(极)显著差异,可能与地理和社会隔离相关,趾间Ⅳ区的特征性Da花纹及弓形纹缺失似可作为藏猴皮纹的一个特征。     

Dermatoglyphic variation among Finno-Ugric speaking populations: methodological alternatives.

Utilization of dermatoglyphics for population studies is apparently increasing, but methods vary widely among investigators. We investigate how different types of dermatoglyphic data can affect estimates of biological distance among Finno-Ugric speaking populations. Dermatoglyphic distances were calculated using the following categories of traits: 1) Finger ridge-counts (radial and ulnar count for each digit), 2) finger ridge-counts (largest count for each digit), 3) finger pattern types, 4) palm ridge-counts, 5) palm patterns, and 6) main-line terminations. In addition, we compare our distances with those of Heet, which rely heavily on summary characters. Distances are evaluated by comparing them to each other and to language and geographic distances. There is considerable variation in the pattern of relationships resulting from the different variable sets. Finger variables, whether ridge-counts or pattern classifications, agree well with each other. Palm patterns, main-lines, and finger variables show moderate agreement with each other, while palm ridge-counts agree poorly with all variable sets except main-lines. Heet's distances agree poorly with all other dermatoglyphic distances. Finger patterns and main-lines are most closely related to language distances, after controlling for geography, while correlations with geography generally disappear after controlling for language. Heet's distances have weak associations with language and geography. Finger variables and palm main-lines yield results which agree best with historical relationships among Finno-Ugric populations. Our results make it very clear that utilization of dermatoglyphics in population studies requires careful consideration of methods, and that summary measures of quantitative or qualitative data should be used with caution.
