Several main results on the evolutions of the life and environment on early earth are summarized as follows:(1) the oxygenation of surface environment didn''t cease until a stable stage for 0.4Ga appeared after 1.6Ga;(2) compared to the isotopic compositions of kerogens and coexisted carbonates, the differences between two can effectively carrier the signals from local environments and bio-assemblages;(3) multiple isotopic relationships between kerogens and individual alkanes in Proterozoic samples were observed, which would depend on the specific biogeochemical processes;(4) repeated biogeochemical changes were observed accompanying Neoproerozoic glaciations, which suggesting that environmental rather than evolutionary forces were driving the biogeochemical changes;(5) the bio-radiations after Neoproterozoic glaciations were definitely suggested by molecular and isotopic data to be at the early Cambrian and after the middle of Doushantuo deposition with different triggers for them.

研究获得以下重要认识：（1）古元古代地表环境的氧化可能一直持续到中元古代早期(约1.6Ga)，而在此之后的4亿年里则保持相对稳定；（2）相对于传统的干酪根和碳酸盐的碳同位素组成，二者之差则能更好反映区域环境的演化特征；（3）在元古代干酪根与单体烷烃类之间存在多种碳同位素组成关系；而其与不同的生物地球化学过程有关；（4）全球海洋生物地球化学特征随新元古代多次冰期出现循环波动，这显然为环境因子的驱动；（5）在新元古代大冰期之后，分子与同位素数据显示地球生命在陡山沱中后期和早前寒武纪出现两次大辐射，然而两次生命辐射的本质却是不同的。

In lower vertebrates, the pineal gland has an eye like structure and it functions as a light receptor and is considered by some to be the evolutionary forerunner of the modern eye.

在较低等脊椎动物里，松果体有一个类似眼睛的结构而它的功能如同光的受体，一些人认为是现代眼睛进化早期的样子。

But that is what two evolutionary biologists, Robert Trivers and Dan Willard, hypothesised nearly four decades ago.

但是如果说是母亲的生殖器官最了解所孕育的下一代，就会让我们感到惊讶了。

But that is what two evolutionary biologists, Robert Trivers and Dan Willard, hypothesised nearly four decades ago.

而这却是罗伯特·特里弗斯和丹。维尔拉这2位进化论生物学家四十年前就提出的假设。

Darwin's book legitimised scientific discussion of evolutionary mechanisms, and the newly coined term Darwinism was used to cover the whole range of evolutionism, not just his own ideas.

达尔文的著作使进化机制的学术性研讨合法化；新发明的词语&达尔文主义&包含了整个进化理论，而不只是达尔文个人的观点。

All evolutionary phenomena can be explained in a way consistent with known genetic mechanisms and the observational evidence of naturalists.

所有的进化现象都可以用符合已知的遗传机制和博物学观测证据的方式来解释。

It is most likely that the common ancestor D also shared trait x. This is because of the Law or Principle of Parsimony - if two species share a trait, it is most likely that their common ancestor shared the same trait, and that events of evolutionary change are rare, and so you should postulate the minimum number of these events.

共同的祖先D也非常可能具有特点x，这是因为俭省原则--如果两个物种都具有一个特点，它们的祖先也非常可能具有这个特点，进化变化事件是非常少的，因此，你应该把这些事件假定为小概率事件。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。
