接着,冰冷的星云物质释放出大量的引力势能,再转化为动能、热能,致使温度升高,加上地球内部元素的放射性热能也发生增温作用,故初期的地球呈熔融状态。

After that, the frozen nebula material released vast gravitational potential energy, which was converted into kinetic energy and thermal energy, causing temperature rise. Besides, the radioactive heat emitted by inner elements of the Earth also boosted the temperature. Therefore, the Earth in the beginning, was in a molten state. 

高温的地球在旋转过程中使其中的物质发生分异,重的元素下沉到中心凝聚为地核,较轻的物质构成地幔和地壳,逐渐出现了圈层结构。

During its rotation, the megathermal Earth was differentiated, with heavier elements sinking into the center and agglomerating as the earth’s core, while lighter material forming the mantle and crust, gradually forming the layer structure. 

这个过程经过了漫长的时间,大约在38亿年前出现原始地壳,这个时间与多数月球表面的岩石年龄一致。

This process lasted for a long time, and finally, primitive crust was taken shape in around 3.8 billion years ago, the time coinciding with the age of majority rocks of moon’s surface. 

生命的起源与演化是和宇宙的起源与演化密切相关的。生命的构成元素如碳、氢、氧、氮、磷、硫等是来自“大爆炸”后元素的演化。

The origin and evolution of life has close relationship with that of the Universe. Those component elements of life as carbon, hydrogen, oxygen, nitrogen, phosphorus, sulphur and the like are all evolved from elements created by the “Big Bang”. 

资料表明前生物阶段的化学演化并不局限于地球,在宇宙空间中广泛地存在着化学演化的产物。

Statistics show that, chemical evolution before biological stage was not limited on the Earth, but wildly existed among cosmic space. 

在星际演化中,某些生物单分子,如氨基酸、嘌呤、嘧啶等可能形成于星际尘埃或凝聚的星云中,接着在行星表面的一定条件下产生了像多肽、多聚核苷酸等生物高分子。

During the process of interstellar evolution, some biological single-molecules, such as amino acid, purine pyrimidine and so on, were possibly formed from interstellar dust or agglomerated nebula. Then, under the certain conditions of the Earth’s surface, biomacromolecules as polypeptide, polynucleotide and so on were created. 

通过若干前生物演化的过渡形式最终在地球上形成了最原始的生物系统,即具有原始细胞结构的生命。

Having undergone several intermediate forms before organic evolution, the most primitive biological system of the Earth, that is, life with original cellular structure, was finally formed. 

至此,生物学的演化开始,直到今天地球上产生了无数复杂的生命形式。

Till then, the evolution of biology began, which has been lasting to today’s enormous and complicated life from on the Earth.
