"The question we asked was whether, using data from 1966 to 2000, we could have predicted cholera outbreaks over the past five years," said Pascual, an associate professor of ecology and evolutionary biology.

&我们问的问题，从1966年至2000年利用数据、我们可以预见爆发霍乱，过去5年来，&Pascual说，副教授生态学和进化生物学。

Current patterns of floral design in Pedicularis must have undergone an evolutionary process of interacting among components of floral traits, and then formed internal relationships among these traits.

马先蒿属植物当前花部结构的变异式样一定是各种花部结构成分在进化历程中相互作用的结果，并在这些成分间形成内在的相关性。

This article from the perspection of evolutionary psychology to explain the causes of this phenomenon,and birth order in different people's character has done a specific analysis.

本文从进化心理学角度解释了这一现象的成因，并对位于不同出生顺序的人的性格做了具体的分析。

Because the photospheric temperature of carbon stars are less than 3000K and the temperature of rich-dust envelope formed by the mass loss is lower, and therefore most of the energy from carbon stars are radiated between 1 to 60um range, in which the vibrational and ro-vibrational bands of many molecules also lies, the study of infrared spectra in this wavelength range is very important to reveal chemical compositions, dust formation process, the atmospheric structure and evolutionary status of stars.

碳星光球的有效温度不超过3000K，同时较大的质量损失率形成了富碳的尘埃壳层，以致于它的辐射能量主要集中在1—60μm的红外波段上，并且许多分子的转动振动能谱也集中在红外，因此在红外波段的研究对揭示碳星化学成份及其分布、尘埃形成过程、恒星大气结构和演化状态都有十分重要的意义。

It is concluded that thermophiles are a biologically and phylogenetically divergent group of prokaryotes that have converged to sustain extreme environmental conditions over evolutionary time scale.

嗜热菌能在极端环境中生存，有独特的种系发育特征，表明它是通过长期进化而来的一个分支。

If physicalistic, materialistic, reductionistic forces turn out to give an adequate explanation to the extraordinary diversity of evolutionary unfolding, then fine, that is what we will include in integral theory.

如果物理主义，唯物主义，简化论最终对于进化的多样性给出适当的解释，那好，这就是要包括在整体论里的。

The orders Magnoliale, Laurales, Piperales, Illiciales, and Ranunculales were selected as a complex outgroup. The evolutionary polarity of each character was determined using the outgroup comparison method. On the basis of the character-coding matrix, the phylogenetic trees were constructed with Camin-Sokal method and Farris-Wagner method, implemented in PHYLIP package.

本文选取24个与睡莲类植物系统发育相关的形态、解剖和花粉性状，以木兰目、樟目、胡椒目、八角目和毛茛目作为复合外类群，采用外类群比较法判断了上述性状的进化极性；以性状状态编码矩阵为基础，应用Camin-Sokal方法和Farris-Wagner方法以及PHYLIP软件包构建分支树。

This review attempts to outline the plant evolutionary developmental biology of Poaceae in terms of disciplinary issues, strategic approaches and specific cases.

试从学科问题、思路方法以及具体例子介绍植物进化发育生物学。

This research consolidated that evolutionary models using w as an indicator of selective pressure provide valuable approaches for analyzing the adaption of protein-encoding sequences. Moreover, it also indicated that Polypodiaceous ferns responded to the terrestrial ecosystem changes initiated by angiosperms through molecular adaption of functional genes such as rbeL.

这些结果一方面显示了基于ω比值检验DNA编码序列分子适应的有效性，另一方面也提示水龙骨类可借助rbcL等功能基因的适应性进化，应对白垩纪被子植物引发的陆地生态系统改变。

In the 1920s Rensch, who like Mayr did field work in Indonesia, analyzed the geographic distribution of polytypic species and complexes of closely related species paying particular attention to how variations between different populations correlated with local environmental factors such as differences in climate. In 1947 Rensch would write a book, eventually translated into English under the title Evolution above the species level, that looked at how the same evolutionary mechanisms involved in speciation might be extended to explain the origins of the differences between the higher level taxa.

在二十世纪二十年代，像迈尔一样从事野外研究的任许在印度尼西亚分析了多型物种的地理分布以及近缘物种复合体系，特别注意了不同群体之间的变异是如何与当地的环境因素相关的。1947年，任许决定写一本书，这本书最终被译成英文，书名为《物种以上水平的进化》；该书研究了参与物种形成的同样的各种进化机制，如何被延伸用于解释更高层次分类单元的差异的起源。

The witness also told the jury at the Royal Courts of Justice in London that he saw a paparazzo fighting with a member of the public who was trying to stop him taking pictures in the minutes before the emergency services arrived.

他还告诉在伦敦皇家法庭的陪审团，在急救服务到来之前，他当时看见一个狗仔队正和一群阻止他拍照的人打架。
