There is a case of an oysterlike bivalve that evolved a more and more spiraled shell until, just before extinction, the valves could barely open.

The rock assemblage and geochemisty of the sedimentary rocks indicate that the Xiong'er Group formed in a passive continental margin and it was mainly a marine facies when lava erupted. Therefore the paleogeographic environment of the Xiong'er Group evolved from continental facies to marine facies then to continental facies again.

沉积岩的岩石学和地球化学特征表明熊耳群形成于被动大陆边缘的构造环境，结合火山岩的结构、构造特征，表明火山喷发的主体环境是海相，经历了陆相到海相再到陆相的演变过程，即：伴随着裂谷的发育、地面沉降和海水的侵入，以及随着火山喷发的进行最后又高出海面暴露于地表的全过程。

Eventually these bizarre, evolved plants populated a video of his creations called Panspermia.

最后这些进化出来的奇怪植物在他的一个叫做&胚种论&[9]的视频作品里随处可见。

A wilder offshoot of this theory, called panspermia, suggests that whole bacteria life itself first evolved on Mars and then hitched a ride to Earth via small pieces of the Red Planet blasted here by asteroid or comet impacts.

Panspermia 是这派之想像力特别丰富的，他们的意见：细菌根本是发源於火星；小行星或大陨石的撞击把火星的碎片带到了地球。

Parasitica system has evolved into a very useful model for understanding the interaction between a virus and its host and for dissecting the virulence regulation of a pathogenic fungus.

低毒病毒／板栗疫病菌系统已经成为研究病毒与宿主相互作用以及病原真菌致病机理的很好的模式系统。

It s not their original modes . Whith the development of human civilization , human society has evolved from matriarchal society to patrilineal society .

从人类文明的历史进程来看，人类社会经历了由母系社会到父系社会的演变过程，神话也经历了由女神神格向男神神格演化的历程。

Compared the similarity and difference of distribution of homologous fragments on X and Y, we suggested that the sex chromosomes of spiny eel have evolved from a pair of homologous ancestral chromosomes, and during the evolution, a pericentric inversion might have occurred on the original Y chromosome, and subsequently terminal regional duplication might have followed, eventually resulting in the differentiation and formation of X and Y chromosomes, then the recombinants between sex chromosomes were repressed, so the sex chromosomes could be inherited steadily.

根据X、Y染色体上同源片段的分布的相似和相异，我们对刺鳅性染色体的分化历程进行了推测，即：刺鳅的性染色体起源于一对原始的同源染色体，通过原Y染色体上的一个明显的臂间倒位，以及染色体末端的异染色质成分的扩增，导致原始Y染色体与X染色体在染色体结构上的分化，从而抑制了X、Y性染色体之间的遗传物质的重组交换，为性染色体的稳定遗传奠定了基础。

Based on these observations, we propose that the periplasmic proteins have been evolved to resist the formation of aggregates when subjected to various denaturing conditions and molecular chaperones may thus not be needed in periplasm.

根据这些发现，我们提出假说：膜间质蛋白在恶劣环境条件的选择压力下进化出对各种变性条件所诱导聚集的抗性，而不需要分子伴侣蛋白的有效保护。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。

On one hand, there are discussions with the works council and union about extension of short time working up to the end of September.
