Genetic divergence and phylogenetic relationships between the chamois (Rupicaprini, Rupicapra rupicapra rupicapra) and three species of the Caprini (Capra aegagrus hircus, Capra ibex ibex and Ovis ammon musimon) have been studied by multilocus protein electrophoresis. Dendrograms have been constructed both with distance and parsimony methods. Goat, sheep and chamois pair-wise genetic distances had very similar values. All the topologies showed that Capra, Ovis and Rupicapra originate from the same internode, suggesting the hypothesis of a common, and almost contemporaneous, ancestor. The estimated divergence times among the three genera ranged from 5.28 to 7.08 Myr. These findings suggest the need to reconsider the evolutionary relationships in the Capriae.
通过多位点蛋白质电泳研究了岩羚羊(山羊亚科,欧洲阿尔卑斯山区岩羚羊)与羊亚科三种动物(家山羊、西班牙北山羊和摩弗伦羊)之间的遗传差异和系统发育关系。使用距离法和简约法构建了系统树图。山羊、绵羊和岩羚羊之间的两两遗传距离值非常相似。所有拓扑结构均表明,山羊属、盘羊属和岩羚羊属起源于同一节点,这支持了一个共同且几乎同时期的祖先的假说。三个属之间的估计分歧时间在528万年至708万年之间。这些发现表明有必要重新考虑羊亚科的进化关系。
