进化的

The results show that the expression of nov mRNA and protein was widely distributed in the CNS of fish, chicken, cattle, dog and cat.

证实，在鱼、鸡、牛、犬、猫这些处于进化的不同阶梯的动物，其中枢神经系统中nov mRNA和蛋白均有广泛的表达，说明nov基因在从低等的脊椎动物进化到高等的脊椎动物的过程中是非常保守的，这种保守性强烈支持这样一种观点，那就是它具有重要的作用。

As the basement to integrate multi-scale spatiotemporal data, the object evolution model can retain the characteristic of the data with different temporal-scale or different spatial-scale, and reflect the temporal changes especially the heteromorphic changes, and the causalities within the evolving process.

本文通过对时空对象变化过程的分析，指出对象进化的结果不仅是特征的变化，还包括机制的变化，其直接动力是对象行为，其根本原因是其内在机制，时空事件起着对象间信息通道的作用，据此提出对象进化模型，该模型可作为多尺度时空数据集成的结构性基础，在反映时空现象的演变过程，特别是异构演变过程，以及在这个过程中产生的因果关系的同时，还可以保留时空数据的不同时间尺度和空间尺度特点，从而达到增加时空数据库的信息量的目的。

At least one suborder of trilobites, the Agnostina , are thought to be primarily eyeless . None have ever been found with eyes. In contrast, a few secondarily eyeless species (in which a clear evolutionary trend toward reduced eye size with eventual disappearence of eyes altogether) have developed within several groups, even those known for large, well-developed eyes ( e.g., Phacopina).

在最少一个亚目的三叶虫 Agnostina 中，通常是盲目的，这类三叶虫从来没有发现过眼睛的构造，以此相对的，一些很少的其他亚盲目的种（一些进化了简单的眼睛的物种）是比较进化的，甚至是一些大个体的，有很好的眼睛发育的种，如 Phacopina。

Endangered Abies yuanbaoshanensis will probably have been extinct,so it very necessary to studying its genetic diversity with a proper way in order to save this key group of biological diversity in China.In the present study,AFLP(amplified fragment length polymorphism) markers was used to examine population of Abies yuanbaoshanensis in order to understand the level of population genetic variation and genetic structure.

首先，物种的遗传多样性是长期进化的结果，是其生存和发展的前提，对遗传多样性进行研究可以为分析濒危物种或种群的进化潜力和未来命运提供重要资料；其次，遗传多样性是保护生物学研究的核心之一，不了解种内遗传变异大小、时空分布及其与环境条件的关系，就无法采用科学有效的措施来挽救濒于灭绝的物种、保护受到威胁的物种，对珍惜濒危物种制定合理的保护方针和策略，有赖于对物种遗传多样性的认识。

The same punctuated equilibrium pattern has been seen in other evolutionary computer models as well, such as Kristian Lindgren's coevolutionary Prisoner's Dilemma world.

在其它进化的计算机模型中也能看到同样的跃变平衡的方式，比如克里斯蒂安林格伦的共同进化的《囚徒的困境》世界。

Deep evolution is an aggregate of many kinds of evolutions; it is a multifaced god, a creator with many arms, working by many methods, of which natural selection of variation is perhaps the most universal factor.

深度进化，是多种进化的聚合；它是一位具有多副面孔的神，一位长有多条臂膀的创造者；它工作的方法多种多样，其中变异的自然选择也许是它应用最广泛的因素。

In this project we use microscopic and submicroscopic technology to research the sperm morphology and its ultrastructure of Leptobrachiinae, discuss the characters and taxonomics of spermatozoa and its utilization on the taxology, relatedness, phylogeny of Leptobrachiinae. this study will provide the new cues for the presented problems about the taxology and phylogeny in this field. Likewise,ultrastrucure of sperm are also disscussed.

本项目采用显微和亚显微技术，对拟髭蟾亚科各属代表种精子的形态结构进行系统地研究，分析各属物种精子的形态结构特征，比较它们的异同，探讨该亚科精子的分类；探讨精子形态分类与该亚科物种的分类和系统进化的关系，为解决一些分类和进化问题提供精子学证据；并对重要种类精子的超微结构进行研究。

I imagine there might be a world of mutating buildings, living silicon polymers, software programs evolving offline, adaptable cars, rooms stuffed with coevolutionary furniture, gnatbots for cleaning, manufactured biological viruses that cure your illnesses, neural jacks, cyborgian body parts, designer food crops, simulated personalities, and a vast ecology of computing devices in constant flux.

没准儿我们将面临一个世界，其中有变异建筑，活生生的硅聚合物，软件程序脱机进化，还有可修改的车辆、塞满共同进化的家具的房间，打扫卫生的蚊型机器人，能治病的人造生物病毒，神经性插座，生控体系统的身体部件，带标签的粮食作物，模拟个性，以及由不断变化的计算机设备组成的巨型生态。

没准儿我们将面临一个世界，它变异建筑林立，活生生的硅聚合物肆虐，软件程序脱机进化，还有可变车辆、房间，里面塞满共同进化的家具，打扫卫生的蚊型机器人，批量生产的用以治病的生物病毒，神经外衣，生控体系统的身体部件，特制粮食作物，模拟个性，以及不断变化的巨型生态学的计算机装置。

In recent years, many studies have suggested that the selective pressure be-tween dispersers and plants is rather weak.

然而，食果动物和植物一对一的协同进化的例证并不多见；适合种子萌发和生长的环境在时空上难以确定；食果动物和植物的进化速度不一致；植物与种子传播者的选择压力存在着高度的不对称和不平衡，加上环境因素的重要影响，这种选择压力受到极大的限制而有可能变得不显著。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
