查询词典 evolutionary tree

In this case, it is most parsimonious to say that x is ancestral and that y was derived , or evolved by B at point c – one step of evolutionary change.

在这种情况下，最俭省的就是x是祖传的并且y是演化的或者B在c点进化得到的--一步进化变化。

This paper presents a tabu search algorithm for constructing evolutionary trees based on maximum likelihood and parsimony criterion.

摘要 这篇论文当中提出一个以禁忌搜寻演算法来建构最大概率条件的演化树与吝啬法的演化树。

He has some evidence that adding parsimony at the end of evolutionary procedure -- that is, first let the system find a solution that kind of works and then start paring it down -- is a better way to evolve succinct equations.

他有些证据可证明，在进化过程的结尾加入简约性——即，先让系统找到一个可行的解决方案，然后再开始把这一方案简化——更有利于演化出简洁方程。

Partial correlation analysis shows that the variance of evolutionary rate explained by the proportion of exposed residues can reach more than half of that explained by translational selection.

经由净相关分析发现，蛋白质中暴露残基的百分比可以解释的演化速率变异量，可达到转译效率的选择力所能解释的一半以上。

A large number of phenomena are modelled by evolutionary partial differential equations.

很多现象的模型是发展状态下的偏微分方程。

Living in a glare of our own making, we have cut ourselves off from our evolutionary and cultural patrimony—the light of the stars and the rhythms of day and night.

当我们生活在自己制造的刺眼强光中时，我们已经阻碍了自身的进化和对文化遗产的继承——即人类的昼夜规律以及闪烁的星光。

The evolutionary relationships were investgated by comparing the results from molecular data alone or molecular data combined morphological characters using different analysis methods: maximum parsimony by PAUP(superscript *) 4.0 and Bayesian inference by MrBayes 3.0B4. Base composition and ti/tv of 28S rDNA D2 regions were analyzed by PAUP(superscript *) 4.0. The results showed that GC content of the 28S rDNA D2 gene sequences of subfamily Euphorinae ranges from 40.00% to 49.25%. Transversion frequency of sequence variable sites among species of Euphorinae was higher than that of transition. The subfamily Euphorinae was proved to be a paraphyletic group with close relationship to subfamilies Neoneurinae and Cenocoelinae; only two tribes, Meterorini and Microctonini, were proved to be monophyletic groups; Centistini, Cosmophorini, Euphorini and Dinocampini were paraphyletic groups; the basal position of tribe Meterorini within Euphorinae was partially supported by our phylogenetic trees, and tribe Microctonini was proved to be a group at the top of the trees.

结果表明：优茧蜂亚科的28S rDNA D2基因序列片段的GC%含量在40.00%~49.25%之间变动，而对于碱基替代情况来讲，优茧蜂亚科各个成员间序列变异位点上颠换大于转换；不同的分析和算法所产生的系统发育树都表明目前根据形态定义出的优茧蜂亚科Euphorinae不是一个单系群，而是一个与蚁茧蜂亚科Neoneurinae和高腹茧蜂亚科Cenocoelinae混杂在一起的并系群；在优茧蜂亚科内部，悬茧蜂族Meterorini和食甲茧蜂族Microctonini（排除猎户茧蜂属Orionis）为单系群，而宽鞘茧蜂族Centistini、大颚茧蜂族Cosmophorini、优茧蜂族Euphorini、瓢虫茧蜂族Dinocampini为并系群；悬茧蜂族Meterorini在优茧蜂亚科Euphorinae内位于基部位置的观点得到部分的支持，同时食甲茧蜂族Microctonini被判定为相对进化的类群。

Je pense, donc je suis - his painting of the red homo sapiens focused on those cold, bright, wise and deepset eyes. The stare was not an allusion to the evolutionary stage from homo sapiens to man, but to force us to contemplate again on all surveillance gaze.

我思故我在，他对红色类人猿的描绘，都集中在那双目光冷酷、炯炯、智慧、深邃的双眼上，在华庆的画上那目光不是暗示类人猿向人类进化的阶段，而是逼迫我们重新思考一切的监督者的视线。

The Permian/Triassic mass extinction plays a great role in the evolutionary history of the Earth.

二叠-三叠纪生物绝灭事件在地史发展中有着重要作用，灭绝加速了物种的进化和更替。

Great. What repertoire did you see?

太棒了。你看的是什么剧目？

I prepared not to accept such ridiculousness:"Please," I said to him.

我可不想理会这套荒谬的东西："请你通情达理一点儿。"
