Here are two:"The known fossil record fails to document a single example of phyletic evolution accomplishing a major morphologic transition and hence offers no evidence that the gradualistic model can be valid," says Stephen Stanley , evolutionary paleontologist.

这里有两个实例：进化古生物学家史蒂芬·斯坦利说：&已知的化石记录未能录得一个完成了主要形态跃迁的种系进化的简单实例，因此也就无法为渐进式模型的有效性提供任何证据。&

Among them, the black rings puts in order salt crust sand content to increase, but the white rings puts in order by the silt and the clay primarily. The light and shade interaction annulus of salt crust granulometric composition difference are showed that the saline lake passed by evolutionary process, because of the climate and temperature changes in turns, which causing the saline lake deposit ingredients have regular change results.

其中，黑色纹理处盐壳含砂量增加，而白色纹理处以粉粒和粘粒为主，明暗相间的环带盐壳颗粒组成差异是盐湖向干盐湖的演化过程中，由于气候冷暖交替变化而使盐湖沉积物成分发生规律性变化的结果。

We also use an evolutionary factor of gener ation ability to make resulting SVMs adaptive on classifying precision and guara ntee the generation ability of them.

同时引入泛化能力进化因子，使得结果SVM在分类效果上具有自动调整能力，并防止分类能力的退化。

Comparative genomics in Salicaceae, Pinaceae, Rosaceae, Fagaceae and Hamamelidaceae had shown that the organization of genomes remained highly conserved over long evolutionary periods and extensive synteny or collinarity or microcollinarity existed in tree genomes.

有关林木比较基因组学研究主要集中在杨柳科、松科、蔷薇科、壳斗科和金缕梅科的一些树种中。

Dr Hazen argues that considering minerals in evolutionary terms is a powerful way to help identify how far a planet has developed geologically.

海森博士认为，考虑矿物的进化特性是确定行星的地质演化时间的有效手段。

Dr Hazen argues that considering minerals in evolutionary terms is a powerful way to help identify how far a planet has developed geologically.

Dr Hazen 认为以进化的方式评价矿物有助于鉴别一颗星球的地质发展时间。

Relationship between DNA content and evolutionary degree DNA contents of bivalves were analyzed statistically with SPSS software at subclass, order, family and species grade respectively. Significant difference was detected between mean values of two subclasses according to the result of T-test. The DNA content of Heterodonta (3.77pg) was distinctly larger than that of Pteriomorphia (3.14pg). It was concluded based on ANOVA that the general trend of DNA content was to change from lower to higher values associated with evolution at higher taxonomical classification, i.e.

核DNA含量与进化地位的关系运用SPSS统计软件，在亚纲、目、科以及种4个分类等级上对双壳贝类的核DNA含量进行了统计分析。T检验结果显示，两亚纲核DNA含量的平均值有明显差异，异齿亚纲的核DNA含量平均值(3.77pg)显著大于翼形亚纲(3.14pg)，该结果表明，核DNA含量在较高的分类等级，即亚纲上表现出随着进化地位的升高显著增大的趋势。

The present study was to construct a computer simulation system to investigate the dynamic load-balancing problem in heterogeneously distributed systems through self-organizing and evolutionary learning algorithms.

本研究主要是以电脑系统模拟方式，利用进化式学习演算法，透过自主式的学习方式，搭配不同网路拓朴，从动态的环境里，探讨异质分散式系统之「动态负载平衡」问题。
