自然选择

Many such extinctions are due to natural forces, while others are due to anthropogenic factors.

许多物种的灭绝是因于自然选择，另一些则是因于人类活动。

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。

Many real-life data examples have been presented in the literature employing LME and NBLME modeling techniquesJones 1993,Davidian and Giltinan 1995,Vonesh and Chinchillo 1996,Pinheiroand Bates 2000,Verbeke and Molenberghs 2000,Diggle et al.2002,and Demidenko2004 among others However for many other practical data example from AIDS clinical trials and other biomedical studies will be presented and used throughout this book for illustration purpose In these amples LME and NLME models are no longer applicable and nonparametric mixed-effects(NPME modeling techniques which are the focuses of this book, are a natural choice at least at the initial stage of exploratory analyses.

The action of selection seems to be fully deterministic .

自然选择的作用似乎是十分确定的。

Another objection holds that if consciousness is epiphenomenal, it could not have evolved by natural selection. The type-E dualist has a straightforward reply, however. On the type-E view, there are fundamental psychophysical laws associating physical and phenomenal properties.

另一个反对认为，如果意识是副现象，那么它不会被自然选择发展出来。E类二元论有一个直接回答：按E类，有基础的心理物理规律关联物理现象属性。
