Platyhelminthes are excellent models for the study of stem cell biology, regeneration, evolutionary and development.

由于其在动物演化的历史进程中处于特殊的演化地位，和极强的再生能力，为我们研究动物起源、进化、胚胎发育及干细胞分子机理等提供了优良材料。

So the evolutionary picture already entails a plurality of minds, but I won't press that.

所以，进化论图式已经蕴涵了心灵的复数，但我不会强调这点。

In order to understand their ecological adaptation process thereby to reveal their phylogeny and to solve problems may be facing in resources development process, the evolutionary ecology of Sinopodophyllum hexandrum and its close related species Dysosma veitchii, Diphylleia sinensis, Dysosma versipellis and Podophyllum peltatum has been studied in this thesis.

为洞悉该类植物的生态适应过程进而为分析它们的系统发育并解决资源开发过程中遇到的一些生物学问题，本论文以繁殖生态学为核心，对桃儿七及其近缘种川八角莲、八角莲、南方山荷叶及足叶草进行了进化生态学研究。

Recently, pollination biology has become a thriving field of inquiry of ecology and evolutionary biology in China.

传粉生物学是近年来在我国迅速发展的一个生态学与进化生物学的分支领域。

Dr Clutton-Brock reckons that the sex difference in both human rates of ageing and in the usual age of death is an indicator that polygyny was the rule in humanity's evolutionary past—as it still is, in some places.

Clutton-Brock 博士估计人类衰老速度的性别差异和死亡的正常年龄标志着一夫多妻可能是人类进化的法则，因为现在在某些地方还存在着这种现象。

Polyploid is a remarkable characteristic in the chromosome evolution of higher plant, and about 70% of angiosperms have experienced polyploidization once or more in their evolutionary history.

多倍体是高等植物染色体进化的一个显著特征，约 70 %的被子植物在其进化过程中曾经历过一次或多次多倍化事件。

Recently polypod ferns have been demonstrated to undergo diversifications in the Cretaceous after the rise of angiosperms. To further test this proposal, an adaptive evolutionary analysis was performed on the rbeL gene sequences of Polypodiaceous ferns under models allowing w (nonsynonymous/synonymous rate ratio) to vary among sites.

为验证蕨类植物在白垩纪适应被子植物兴起而发生分化的观点，本研究以水龙骨科附生蕨类为对象，利用位点间可变ω（非同义替换率d和同义替换率d的比值）模型对其rbcL基因的适应性进化进行分析。

Population genetics is one of theory cores in evolutionary biology, genetics and conservation genetics.

群体遗传学是进化生物学、遗传学和保护遗传学研究和发展的一个理论基础和核心内容。

This paper we presents an evolutionary game theory approach for portfolio selection.

给出证券组合选择的一个进化博弈方法。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
