If you consider brachiation, flight, and swimming from a broader evolutionary view, most animals rely on their "arms", from birds to whales to sea lions to fish.

"This is an excellent study," says Dennis Bramble, an evolutionary morphologist at the University of Utah in Salt Lake City.

The evolutionary trees of SARS - CoV and SARS - like CoV were made up by using the Brede virus as outgroup, and analyzed variation in single nucleotide sequence.

结果：发现两次SARS自然流行的病毒可分为两个明显不同的聚类；第二次流行时从人类中分离的SARS冠状病毒和从果子狸等动物中分离的SARS样冠状病毒可分为两个基因型，两型的主要鉴别依据是病毒的全基因组变异而非Spike基因序列。

Methods: We analyzed nucleic acid sequence of the SARS-CoV and SARS-like CoV which were obtained from the GeneBank. The evolutionary trees of SARS-CoV and SARS-like CoV were made up by using the Brede virus as outgroup, and analyzed variation in single nucleotide sequence.

对GenBank登录的SARS冠状病毒和SARS样冠状病毒(SARS-like CoV)核酸序列进行了分析，以Breda病毒为外组，构建了SARS冠状病毒和SARS样冠状病毒系统进化树，并进行单核苷酸变异分析。

Bryophyte spores have three types of aperture, the trilete is original one, the monolete is the evolutionary character and the katalept is mostly common one.

苔藓孢子的萌发孔有3种类型：三裂缝为原始类型，单裂缝是进化性状，近极薄壁区是最常见的。

Looking like an evolutionary descendant of the original 1964 model year 901, the Carrera Cabriolet is pure Porsche through and through.

看上去像一个渐进的后裔，原1964年车型年901卡雷拉敞篷车是纯粹的保时捷通过和通过。

According to the dendrogram by UPGMA cluster analysis using Neis(1972) distance calculations based on AFLP banding, all the accessions were distinct and revealed enough genetic diversity for identification and classification of accessions within Cajanus cajan. From ME cluster analysis, 9 distinct evolutionary groups were detected. The preliminary results indicated that China maybe one of the pigeonpea genetic diversity minor center.

根据AFLP多态性数据绘制的聚类图，将139份木豆资源分为9个类群，并在分子水平上初步探讨了它们之间可能存在的演化关系，支持了木豆起源于印度，并在非洲东部形成次生起源中心的观点，并提出中国可能是栽培木豆的又一次生起源中心。

The transition between the Cambrian and the Ordovician periods is crucial in evolutionary history.

之间的寒武系和奥陶系过渡时期是在进化史上的关键。

You can snipe the second and third union leaders from this position.

您可以鹬第二和第三工会领袖从这一立场出发。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
