太行山猕猴掌骨和跖骨的不对称性

了解太行山猕猴掌骨和蹠骨长度的不对称性.对掌骨(35例)和蹠骨(33例)的长度变量进行测量,SPSS13.0统计软件进行正态分布检验.结果表明:5根掌骨有明显的左侧方向不对称趋势,5根跖骨没有发现方向不对称.结果表明左侧掌骨有大于右侧掌骨的趋势,跖骨作为对照组有右侧大于左侧的优势,但没有达到统计学的差异水平.提示上肢骨...

Bilateral Asymmetry in the Metacarpals and Metatarsals of the Macaque

This intention of this paper is to survey the bilateral asymmetry of the lengths of metacarpals and metatarsals in a group of adult Macaque(Macaca mulutta) skeletons.The skeletal material comes from the wild macaque population which exist in Taihang mountians.The lengths of 35 metacarpals and 33 metatarsals are obtained for all possible pairings of the five bones in each individual hand and foot.Lilliefors tests,Shapiro-Wilk tests and one-sample t-test by SPSS 13.0 are used to study the normality and sex differences of asymmetry in metacarpals and metatarsals.The research suggests that the left metacarpals show at endency toward greater length than the right,and the right showed at endency toward greater ones than the left in metatarsals as a control,but this does not reach statistical signicance.The results suggests that the metacarpals results are not a product of fluctuating asymmetry.These finndings imply behavioral laterality in metacarpals and metatarsals in Macaca mulutta.
