Abstract
The taxonomic identity of canids of the genus Canis in North Africa has been investigated using molecular phylogenetic analysis based on Cytochrome b mitochondrial DNA sequence analysis. Tissue samples from 18 Canis specimens collected from all known populations/taxa in Egypt were obtained and analyzed. The resulting Cyt b mt DNA sequences of current Canis taxa, described based morphological characters were compared to each other and to other Canis populations/taxa across North Africa and the Middle East. The results showed no detectable sequence differentiation among all populations, suggesting that the separation of the phenotypically differentiated populations of Egypt has been relatively recent. Estimate divergence time between different phylogroups of the genus and the phylogeographic history of the genus was discussed in a regional paleogeographic context.
采用基于细胞色素b线粒体DNA序列分析的分子系统发育分析方法，对北非犬科动物进行了分类鉴定。从埃及所有已知种群/分类群中收集的18只犬标本进行组织样本分析。基于形态特征描述的现有犬类分类群的Cyt b mt DNA序列相互比较，并与北非和中东的其他犬类种群/分类群进行比较。结果显示，在所有种群中没有可检测到的序列分化，这表明埃及表型分化种群的分离是相对较近的。在区域古地理背景下讨论了该属不同系群之间的分化时间估计和该属的系地理历史。
