Tooby and Cosmides proposed some rules about functional analysis:①functional analysis should be expressed in adaptationist terms,②a set of phenotypic properties is not an adaptation if it is transient, varying from individual to individual,③adaptations should be distinguished from their expression (which may vary from context to context),④a set of phenotypic properties is not an adaptation if it was absent in the environment of evolutionary adaptedness,⑤a set of phenotypic properties is not an adaptation if it did not solve an adaptive problem in the environment of evolutionary adaptedness.

图比和考斯米戴丝提出了功能分析的原则:①功能分析应该用适应的术语来表达;②一系列表现型的特点如果是暂时的,在不同的个体身上发生变化,它并非是一种适应;③适应应该与它们的表现(在不同的情景中可能发生变化)区分开;④一系列表现型的特点如果在进化适应性环境中不存在,则不是一种适应;⑤一系列表现型的特点如果不能解决进化适应性环境中的一种适应性的问题,也不是一种适应。

Combining the shortcoming of multi-objective evolutionary algorithm based on the idea of objective space dividing with high calculation complexicity, this paper proposed an improved new algorithm which processed following characters: transforming the dominance relationship among individuals' Pareto to the rank relationship of sum index of interval in dividing space; simple and efficient environmental choosing method based on index ranking; an individual crowding algorithm which rapidly choosing the nearest to origin.

针对现有基于目标空间分割思想的进化算法计算时间复杂度高的缺陷,提出了一种改进的基于目标空间分割的多目标进化算法。该算法具有以下特点:把个体之间的Pareto支配关系转换成分割区间索引值排序关系的目标空间分割算法;简单高效的基于区间索引值排序的环境选择算子;一种快速的优先选择最接近分割区间原点的个体拥挤机制。

There are no distinct differences between ancestral character state and descendant character state in some characters. 4. Only one outgroup can't give enough information to tell what the ancestor looks like. It make us not to understand how a lot of charactors evolved. 5. The matsutake group is polyphyletic. 6. The character coding is not precise enough. 7. Some characters are not homology. The result of molecular systematic study on the matstuake group shows the group is not monophyletic. The matsutake group is more closed to Tricholoma than Armillaria. ITS sequence of Catathelasma ventricosum is nearly identical to that of the matsutake group, although apparently they are very different from each other in morphological characters.

对松口蘑群通过形态学特征进行系统发育关系分析造成很大的干扰的原因有:松口蘑的种类大多形态特征比较简单,可提供进行分析的特征不多;某些性状在一些状态之间的反复转化,造成分析上的误差;在进化过程中某些性状无明显的祖征和衍征,在分析过程中很难确定进化极性;选择外群时应该用一个特定类群进行整体理解后,确定各个性状的极性,不要只用单种作为外群;松口蘑群是一个多系群;进行比较的性状不一定是同源的;数量性状编码过于粗放,反映不出真实的情况。

In order to direct the construction of plant germplasms by elucidating the relatives among plants at the level of gene, CYP86MF gene analogues from 11 species of 6 genera in Cuciferae were respectively obtained by PCR strategy using gene specific primers designed from conserved regions of CYP86MF gene reported. Sequence comparisonindicated that the similarities among the genes at nucleotide level were over 80%, and the similarities at amino acid level remained above 70%. The differences between the genes at nucleotide and amino acid level between species were 1.0%~ 5.7% and 2.6%~ 7.3% respectively, while those between genera 5.6%~ 22.5% and 7.3%~ 31.2%, respectively. Phylogenetic analysis showed that Brassica was closely related to Raphanus, followed by Rorippa Scop, Arabidopsis Heynh, Capsella Medic orderly, most distantly related to Orychophrogmus.

为了从分子水平阐明十字花科植物间的亲缘进化关系,给植物种质资源的创建提供理论依据,试验根据课题组已报道的CYP86MF基因编码的氨基酸保守区域设计特异引物,运用PCR技术分别从十字花科6个属11个物种中分离克隆到了CYP86MF基因的同源序列,经比较分析,结果表明:这些同源序列的相似性达80%以上,所推导的氨基酸序列相似性达70%以上,且两者种间差异分别为1.0%~ 5.7%和2.6%~ 7.3%,属间差异分别是5.6%~ 22.5%和7.3%~ 31.2%;由氨基酸序列构建的分子系统树可知,在亲缘进化关系上芸薹属与萝卜属较近,其他依次为蔊菜属、拟南芥属、荠菜属,而与诸葛菜属最远。

To summarize molecular, morphology, chromosome and pollen characters, the conclusion was reached that Epimedium was an nd monophyletic taxon. To divide the genus into any groups would be artificial. It is proposed that the disjunction by space, climate and seas were the main reason of respectively differentiation of each group by the view of geographic and climate changes in the temperate zone of the world. Because of its evolution-conservation, the disjunction did not bring about obvious divergence on the level of molecular and morphology.

综合分子特征和形态、细胞学、孢粉学等性状,提出淫羊藿属是一个进化上极为保守的、自然的单系的植物类群,进行属下任何阶元的划分都将是人为的,从旧世界温带的地质变化及气候变迁的角度推测,空间、气候和海洋的隔离是产生类群各自分化的主要原因,但由于其进化上极度保守,这些隔离尚未产生出类群间形态上和分子水平上的明显趋异。

Deep evolution is an aggregate of many kinds of evolutions; it is a multifaced god, a creator with many arms, working by many methods, of which natural selection of variation is perhaps the most universal factor.

深奥的进化过程,实际上是由多种类型的进化过程所叠加在一起而总和而成的,它是那种具有多副面孔的神,一位长有多条臂膀的创造者,它通过多种不同的方法来进行它的工作,而在这些方法之中,对变异的自然选择,也许是一种应用最为广泛的因子而已。
