大进化

A new method to solve the combinatorial optimization problems with mixed evolutionary algorithm based on natural scale enumerative system coding was proposed in this paper. Elitism strategy, one-point crossover and Gaussian mutation were used in the algorithm. An ingenious method for operation among big parameters was designed, which can avoid overflow and simplify the operation.

在自然进位制编码的基础上，算法采用了遗传算法的单点交叉算子和进化规划的高斯扰动算子，并运用了精英保留策略；算法实现时采用逐位运算法实现大数值运算，避免了运算溢出，减少了运算量。

It is because of this they need to have areas of suitable eucalypt forest, which are large enough to support a healthy koala population and to allow for expansion by maturing young koalas.

正因为如此，他们需要有合适的桉树森林地区，这是大到足以支持一个健康的考拉数量和允许年轻考拉向成熟进化

It points out that cultural evolutionism has three presuppositions which have been retorted much.

从文化发展的模式来看，有早期的线性进化主义到后来的文化相对主义两大类，各种学派争论不休。

The most imposing of all tasts confronting the evolutionist is that of accounting for the existence of the first cell.

进化论者所面对不能逃避的最大难题是如何解释第一个细胞的存在。

The Evolver software optimizes the broadest possible profile for the largest number of patients by trying a description of a typical patient, then testing how many fit that description, then tweaking the profile in a multitude of directions to see if more patients fit it, and then varying, selecting, and varying again, until a maximum number of patients fit the profile.

通过描述一名典型患者，然后检查有多少病例符合这份简介，再全方位修改简介，看看是否多数患者都与之相符，然后修改、选择、再修改，直至最大数量的患者符合这份简介，"进化者"软件为最大多数的患者优化了尽可能清楚的简介。

In this paper, big-leaved fig wasps fly out of the formation of channel-depth research to on the tree - fig wasp coevolution valuable basis for research.

本文对大叶榕小蜂出飞通道的形成进行深入的研究，以期对榕树—榕小蜂协同进化关系研究提供有价值的依据。

What we need is integration of the data and precepts of everything from molecular biology to the geobiology of mass extinctions and evolutionary rebounds - entities and processes of vastly different spatiotemporal dimensions.

我们需要的是整合数据资料和一切教训，从分子生物学到大灭绝和进化反弹的地理生物学——差异极大的时空尺度中的实体和过程。

This study showed that population genetic diversity was much lower than other Gymnosperm and there was no distinct genetic differentiation among individuals in this population. In order to protect or preserve its genetic resource,it is suggested that the most individuals in the population should be selected as we can.

研究结果表明：AFLP方法是一种十分有效的检测种群遗传多样性的分子标记，既具有可靠性又有方便高效性；元宝山冷杉种群的遗传多样性水平很低，种群内各个个体间的相似性系数很大，遗传关系很近，无明显的遗传分化，这说明该种群的适应能力差、进化潜力有限，濒危程度很高；若要保护或保存这个物种的遗传资源，建议应该选择种群内尽可能多的个体进行保护。

The third: a round-step, half step-by-step evolution version can be used to deal withbefore and after half-step or a step-by-step, step-by-step round of the advantages is that it's flexible, as long as theother side of a knife does not, then you have a good chance to kill Flying The enemy or the enemy's injury.

第三：圆步，半圆步的进化版，可以用来对付前后步或者半圆步，圆步的优点在于它的灵活机动，只要对方出刀不中，那么你就有很大的机会飞刀杀敌或者伤敌。

The phylogenetic analysis of 22 ND4L sequences of Phocidae from GenBank showed that there are two clades (which belong to Northern Group and Southern Group) supported by relatively high bootstrap value and there are more closed relationship between spotted seal and harbor seal.17 haplotypes with 717bp were obtained from the mtDNA control region, adjacent proline and a portion of the threonine tRNA genes of 46 individuals.

利用从GenBank中下载的22个海豹科动物的ND4L基因序列的系统进化分析表明，海豹科动物分为南半球和北半球两大类群，斑海豹与港海豹为北半球种类，亲缘关系最近。从46个辽东湾斑海豹线粒体DNA控制区和苏氨酸及脯氨酸tRNA基因717bp片段的测序，得到17个单倍型。

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。
