Relationship between DNA content and evolutionary degree DNA contents of bivalves were analyzed statistically with SPSS software at subclass, order, family and species grade respectively. Significant difference was detected between mean values of two subclasses according to the result of T-test. The DNA content of Heterodonta (3.77pg) was distinctly larger than that of Pteriomorphia (3.14pg). It was concluded based on ANOVA that the general trend of DNA content was to change from lower to higher values associated with evolution at higher taxonomical classification, i.e.

核DNA含量与进化地位的关系运用SPSS统计软件，在亚纲、目、科以及种4个分类等级上对双壳贝类的核DNA含量进行了统计分析。T检验结果显示，两亚纲核DNA含量的平均值有明显差异，异齿亚纲的核DNA含量平均值(3.77pg)显著大于翼形亚纲(3.14pg)，该结果表明，核DNA含量在较高的分类等级，即亚纲上表现出随着进化地位的升高显著增大的趋势。
