Relationships of epidermal ridge patterns with body measurements and their possible evolutionary significance

It is commonly believed that in humans epidermal ridge patterns are in regression relative to nonhuman primates, and they play no role in adaptive processes. In contrast with this we have found relationships between anthropometric and dermatoglyphic measurements in a sample of 61 normal males. Anthropometric variables included limb, trunk, head, and face measures. Dermatoglyphic variables included finger ridge counts and pattern intensities and ridge breadth in the palmar interdigital area II. The strongest relationship is between the type and size of pattern on the thumb and the breadth of ridges, and wrist width, which accounts for nearly 30% of the total variance in these traits. These findings identify previously unknown sources of variation in dermatoglyphic patterns and indicate that the dermatoglyphic-anthropometric relationships might have resulted from selection pressures in evolution of modern man.     

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.     

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。     

内蒙地区蒙古,汉,回,朝鲜族肤纹特征比较研究

本文分析了内蒙地区３２３７例蒙、汉、回、朝鲜族人手肤纹特征,选用２２项肤纹参数进行民族间和同一民族不同性别间比较,并与我国其他８个民族的部分肤纹参数进行聚类分析,结果表明,内蒙地区这４个民族同属我国北方群,其肤纹既有各民族自身的特点,又具蒙古人种的一般特征。

汉族左利人群的指纹研究

对111名长治市的汉族左利手者的指纹进行了分析研究, 并与138名右利手者组成的对照组进行了对比分析, 发现左利手组的双箕斗纹（Wd）显著高于对照组(P<0.005)。 Abstract　To study the distribution difference of fingerprint patterns between left-handed and normal populations of Han nationality in Changzhi area, We investigated the frequencies of fingerprint pattern combinations in one or two hands. Comparing the normal population (80 men and 58 women), the left-handed population (58 men and 53 women) posessed higher Wdrate (P<0.005).     

Dermatoglyphics of Apache and Navajo Indians

The Apaches and Navajos, both members of the Athapascan Family, have lived in the Southwest for several hundred years. Finger and palmar dermatoglyphics were collected from 94 Apaches and 102 Navajos. Both tribes exhibited characteristics similar to those generally reported for American Indians, such as, high whorl frequencies, high total ridge counts, longitudinal alignment of main lines, and high frequencies of absent C lines. Absence of significant intertribal differences indicates close genetic relationship between these tribes.

Digital dermatoglyphics of 107 Bengalis.

I analyzed the finger prints of 59 male and 48 female unrelated Bengalis in a rehabilitation camp of Dacca, Bangladesh. The most common pattern type in the Bengalis was the ulnar loop (53%), then whorls (40%); arches (5%) and radial loops (2%) were the least common. Radial loops occurred most frequently on the index fingers. I have shown the arch/whorl, whorl/loop, and pattern intensity indices, and I have presented ridge counts by individual digits and by total digital ridge count. Digital dermatoglyphics in the male Bangladeshis were similar to previous findings in male Brahmins of Bengal. However, there were more whorls and arches, fewer loops, and a higher mean total digital ridge count in the female Bangladeshis than in female Brahmins.
