The overall evidence of the maximum likelihood, as well as maximum parsimony, analyses strongly suggests that Rodentia is an outgroup to the other four eutherian orders, and that Cetacea and Artiodactyla form a clade with Carnivora as a sister taxon, consistently with the molecular phylogenetic studies of previous authors. However, analyses of individual proteins do not necessarily conform to this conclusion, and some of the proteins reject the putatively correct tree with nearly 5% significance. Furthermore, the 12S mitochondrial ribosomal RNA sequences do not give the putatively correct tree irrespective of the alignments and of the phylogenetic methods, although the tree is not rejected with a statistical significance. The 16S ribosomal RNA sequences give the putatively correct tree with our sequence alignment when the ML method is used, but the result depends on the alignment and on the choice of outgroup species. These results illustrate the limitation of the ribosomal RNA data alone in phylogenetic inference, and suggest that we must analyze as many genes as possible and synthesize the results to draw a reliable conclusion.","PeriodicalId":13120,"journal":{"name":"Idengaku zasshi","volume":"69 5","pages":"455-72"},"PeriodicalIF":0.0,"publicationDate":"1994-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1266/jjg.69.455","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18994056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, these rates were discussed in connection with the neutral theory of molecular evolution. It was common to all the five pathogenic viruses that the rate of synonymous substitution was higher than that of nonsynonymous substitution particularly when the entire gene regions were compared between different isolates. This suggests that the viral proteins are quite conservative to functional and structural changes even though most of these viral genomes are evolving at a speed extraordinarily higher than their host genomes. Thus, this feature is consistent with the neutral theory. However, it is also pointed out that positive selection may be operating on some specific sites such as antigenic sites in order for the pathogenic viruses to escape from the host immune system.","PeriodicalId":13120,"journal":{"name":"Idengaku zasshi","volume":"69 5","pages":"481-8"},"PeriodicalIF":0.0,"publicationDate":"1994-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1266/jjg.69.481","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18994058","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using nineteen protein data, we first reexamined the hypothesis of rodent polyphyly proposed by Graur et al. (1991) based on the four taxon system, consisting of human, mouse (or rat), guinea-pig and an outgroup. The ML analysis does not support the rodent polyphyly, but strongly favors the traditional view of rodent monophyly representing the Myomorpha-Caviomorpha association. In the second analysis, the phylogenetic position of Lagomorpha were reexamined using three sets of multiple protein data, 13 mitochondrial DNA-coded proteins from rodents, rabbit, human, seals, bovine, whales and opossum, 25 protein data from human, rabbit and rodents and an outgroup, and 20 protein data from human, rabbit, bovine (or pig) and rodents. Our analysis favors the closer affinity of Lagomorpha to Primates than to Rodentia. The branching sequence of seven mammalian groups revealed by the present analyses is as follows: Myomorpha-Caviomorpha clade (Rodentia), rabbit, Primates, Carnivora, and Artiodactyla-Cetacea clade. Judging from the branch lengths measured by the numbers of synonymous substitutions, a series of divergence of these mammals is likely to be bush-like. The rapid rate of rodent evolution was reexamined in the light of the new phylogeny.","PeriodicalId":13120,"journal":{"name":"Idengaku zasshi","volume":"69 5","pages":"555-66"},"PeriodicalIF":0.0,"publicationDate":"1994-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1266/jjg.69.555","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18994061","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
