Analysis of data obtained from molecular hybridization of 3H-labeled repetitious DNA has been utilized to reconstruct the broad outlines of phylogenetic relationships among decapod Crustacea. This molecular reconstruction agrees reasonably well with the paleontological record, and with other schemes obtained by comparative morphological and serological approaches. Preliminary evidence is in line with the hypothesis that continuous addition of new repeated sequence families to the genome over long periods of time may in part account for the correlation observed between percent repetitious DNA hybridized and divergence time. It is tentatively concluded that a core of DNA base sequence homology has been highly conserved throughout the evolution of the Crustacea. Demonstration of inter-species sequence homology has important implications to models which relegate a genetic regulatory function to repeated DNAs.
对从3H标记的重复DNA分子杂交中获得的数据进行分析，已被用于重建十足目甲壳纲动物系统发育关系的大致轮廓。这种分子重建与古生物学记录以及通过比较形态学和血清学方法获得的其他分类方案相当吻合。初步证据支持这样的假说：长期以来基因组中不断添加新的重复序列家族可能部分解释了观察到的杂交重复DNA百分比与分歧时间之间的相关性。初步得出的结论是，在甲壳纲动物的整个进化过程中，DNA碱基序列同源性的核心一直高度保守。种间序列同源性的证明对那些将遗传调控功能赋予重复DNA的模型具有重要意义。
