A sort of autonomous agent construction method based on adaptive symbiotic evolutionary model was proposed,and by using adaptive symbiotic evolution algorithmas an evolutionary reinforcement learning method,Which can design neural network decision making systems effectively. while at the same time this method can accelerate the learning and convergence speed in the behavior evolution problem of multi agent autonomous system,and it also prevents premature convergence and promotes population diversity.

The RT-PCR product was inserted into pTG19-T vector and transformed into E. coli successfully. By blastn, the sequence results of Kunming mus musculus were in complete accordance with the conservative sequence of Genbank NR_003278 (791bp-1153bp). By Blastn in NCBI, the sequence with little difference among animals was confirmed to be conservative. After Blastn, fourteen complete CDS coding for different animals were chosen. According to VECTOR NIT 9.0 software, the similarities between Kunming mus musculus and bos taurus, homo sapiens, erinaceus europaeus, cricetulus griseus, sus scrofa, dasypus novemcinctus, rattus norvegicus, rabbit, equus caballus, macaca fascicularis, didelphis virginiana, monodelphis domestica and vombatus ursinus was 67%, 100%, 100%, 36%, 100%, 100%, 67%, 100%, 100%, 92%, 99%, 99% and 99%. In the phylogenetic tress constructed with the forteen 18S rRNA by Treeview, the Kunming mus musculus clustered with cricetulus griseus, sus scrofa and rabbit, which was nearer to cricetulus griseus and was most far away from macaca fascicularis.(3) After sencodary structure analyses of 18S rRNA of mus musculus, an oligonucleotide fragment for RNAi was designed and synthesized, which was transformed into plasmid, and restriction enzyme analyses and sequencing results should the expression plasmid pGPH1/ GFP/Neo-mouse-sh 18S rRNA were constructed for RNAi successfully.
结果①通过RT-PCR检测显示18S rRNA基因在小鼠卵巢组织和单个GV期、MⅠ期卵母细胞中均有表达,且在未成熟卵母细胞中,MⅠ期的表达明显强于GV期的表达;②RT-PCR产物克隆测序结果显示:昆明小鼠18S rRNA基因保守区序列与基因库序列[NR_003278保守区部分(791bp~1153bp)]完全一致;Blastn比对结果发现:在不同物种中差异较小,选出14种生物18S rRNA全序列经VECTOR NIT 9.0软件分析,提示昆明小鼠18SrRNA与牛、人类、刺猬、中国仓鼠、猪、犰狳、褐鼠、兔子、马、食蟹猴、负鼠、短尾猊、袋熊的18S rRNA的相似率依次为67%,100%,100%,36%,100%,100%,67%,100%,100%,92%,99%,99%,99%;Clustal 1.81和Treeview构建出的分子进化树表明:在上述14种生物中昆明小鼠与中国仓鼠进化关系最近,与兔子、猪聚成一簇,与食蟹猴进化关系最远;③根据18S rRNA二级结构设计并合成RNA干扰寡核苷酸片段,重组质粒经过限制性内切酶及测序表明成功构建了pGPH1/GFP/Neo-mouse-sh 18S rRNA干扰表达质粒。

I suspect that women evolved breasts which didn't disappear after breast feeding, and that this led to the evolution of men's lust for breasts, and that following this, nulliparous breasts evolved in response to the new lust.
我猜测先是女人进化出不会在母乳喂养结束后消失的乳房,然后这导致了男人进化产生对于乳房的色欲,接着,未产妇对这种新出现的色欲做出回应,进化出了乳房。

After some preliminary paragraphs excoriating evolution (and sarcastically asking whether a 'Negro' is 'still in the process of evolving'), insulting Darwin personally, misquoting Huxley as an anti-evolutionist, and encouraging me to read a book which argues that the world is only eight thousand years old can he really be a doctor?
首先,他严厉地抨击了进化论(滑稽的是,他还问我,黑鬼是否还未进化完成),然后,对达尔文进行人身攻击,错误地把赫胥黎当作反进化论来引用,鼓励我去读一本我已经读过的书,证明世界仅有8000年

The paper introduced the composition of every subunit and their functions. Based on the cloned subunits from GenBank, the phylogenetic was constructed by Mega 4, which was helpful to understand molecular evolution of every species. Meanwhile, several original authors unlabelled α1 subunits type of calcium channels from GenBank were concluded according to the phylogenetic tree.

nullipara:未产妇
一个未产妇(nullipara)是还没有生过孩子的女性. 很奇怪的是,我们都知道"处女"这个词,却很少有人知道"未产妇"这个词. 以上我们解释了进化出存在于不分泌乳汁时的乳房是如何成为可能的,但是这距离解释为什么它们最终被进化出来还有很远的距离.

second genetic code:第二遗传密码
de Duve)提出的第二遗传密码(second genetic code)观点,以及近些年主体研究领域提出的立体化学理论和共进化理论等. 尽管如此,关于遗传密码起源和进化的问题至今仍未得到令人满意的诠释,特别是在如何解释遗传密码的分配原则以及与生命体多样性的关系上.
