Taken together, the findings provide support for the hypothesis that anatomical differences affecting gait existed among our earliest apelike ancestors, and that these differences provided the genetic variation which natural selection could act on when changes in the environment gave bipeds an advantage over quadrupeds.

第六段告诉了我们研究的两个假设：一种假设：猿人祖先在解剖学意义上存在着差异，这一差异影响了它们的步态；另一种假设：这些差异为自然选择所决定的遗传变异提供了可能性，而环境变化使得两足行走的猿人比起四足行走的猿人更有优势。因此B是答案。

An optimized PCR reaction system for ISSR analysis was established:PCR was performed in a 20μl reaction mixture with 5μmol/L DNA, 2.5mmol/L Mg~(2+), 0.3mmol/Lof each dNTP, 300nmol/L primer, 1U Taq polymerase and 1×Buffer. Using 9 ISSRprimers,the genetic diversity among 23 Arrhenatherum elatius L.
