【摘要】 对康多兀鹫和秃鹫骨骼进行了系统地比较。康多兀鹫和秃鹫的脊柱、前肢骨结构基本相同;头骨、肩带、后肢等部位具有明显差异。骨骼系统的特点与其各自的取食方法和偏好、飞行和栖息特点密切相关;也反映了它们可能是经历了趋同演化,亲缘关系较远的两个物种。更多还原

【Abstract】 A complete comparison on skeleton of Andean condor and cinereous vulture was carried out.The two species are nearly identical in the bones such as vertebral column and forelimbs,meanwhile,there are still some distinct differences in the skull,pectoral girdle and hindlimbs.The correlations between morphological characteristics and functional adaptation are discussed.The relationship between them is not as nearly as expected,and the similarities of two species might result from convergent evolution.更多还原
