猴与人掌(跖)纹的比较研究

Comparative Studies of Dermal Ridge of the Palms (Soles) between Monkeys and Men

本研究对猴和人的手 (脚 )掌纹进行了观察 ,并应用 χ2 检验进行比较分析 ,结果显示 :(1)指 (趾 )间区、小鱼际区、脚弓区纹型出现频率 ,猴远远高于人。猴指 (趾 )间区纹型出现频率达 95 .5 %以上 ,而人的指间区最高的Ⅰ4为 72 .1% ,最低的Ⅰ1仅为 1.0 % ,趾间区fⅠ3 为 34 .6 % ,fⅠ1是 3.7% ;猴的手掌小鱼际区纹型频率为 131.8% ,脚掌小鱼际区为 5 9.1% ,而人分别为 14.4%和 18.5 % ;脚弓区也类似。 (2 )上述区的纹型类型 ,猴与人也有明显差异。最明显的特点是猴的斗形纹频率明显高。如指间区、趾间区、手掌小鱼际区和脚掌小鱼际区的斗形纹频率分别是 77.3%、40 .9%、5 9.1%和 2 2 .7% ,而人分别为 0 .1%、0 .3%、0和 0。本研究结果对研究灵长目皮纹的遗传与进化有重要意义。

Dermal ridges of palms (soles) in monkeys and men were observed.Using the method of χ 2 examination to make a comparative study and analysis.The results showed the ridge pattern frequencies of the monkeys in their interdigital areas were much higher than men.The ridge pattern frequency of the monkeys in each interdigital area and sole interdigital area was over 95.5%,but men’s Ⅰ 4 was 72.1% at the highest, and Ⅰ 1 was only 1.0% at the lowest, fⅠ 3 was 34.6% and fⅠ 1 was 3.7%.The ridge pattern frequency of the monkeys in their hypothenars of palms was 131,8%,soles was 59.1%,but that of men were 14.4% and 18.5%.These similar phenomenon also existed in the arch areas of the feet.There were obvious differences between monkeys and men in their types of ridge patterns.The obvious character was that the whorl frequency of the monkeys was obviously higher. For example ,the whorl frequency of the monkeys in their interdigital areas and sole interdigital areas ,hypothenar of the palms and sole were 77.3% and 40.9%,59.1%and 22.7% respectively.But those of the men were 0.1% and 0.3%,zero and zero.The results are very significant for researching the inheritance and evolvement of the primates'dermal ridges.
