Cladistics creates testable hypotheses of phylogeny that also give a highly informative summary of available data. Thus it best fits the criteria for a method for determining the general reference classification in biology. For protistologists in particular, cladistics is especially useful. Inundated by an abundance of ultrastructural, biochemical, and cell biological information, protistologists could be greatly helped by the informative way in which cladistics orders and summarizes the data. In addition to classifying protist taxa, hypotheses about the evolution of cell organelles and cellular could be scientifically formulated and tested by cladistics . Because cladistic classifications best summarize the data, they would also be best for making predictions about taxa and characters. They would, for the same reason, be the most stable. Widespread adoption of cladistic methods would serve to stabilize the now fluid state of protist taxonomy. It is for all of these reasons that such methods best suit the needs of the evolutionary protistologist .","PeriodicalId":76288,"journal":{"name":"Origins of life","volume":"13 3-4","pages":"235-48"},"PeriodicalIF":0.0,"publicationDate":"1984-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF00927175","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17487585","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}

Some generalizations concerning the relative migration rates of alpha VS beta tubulin could be made, in particular the alpha/beta inversion, first described in Physarum was extended to several ciliates. Antivertebrate tubulin antibodies displayed a very broad spectrum of reactions, reacting with virtually all the species tested. They appear to correspond to auto-antibodies no exclusively directed against species specific determinants. In contrast, the two anti-ciliate tubulin antibodies displayed a narrow species specificity reacting only with a limited subset of protists. They were shown to be specific for a small number of immunological determinants present on ciliate tubulins. This allowed a rough evaluation of evolutionary relatedness between the various groups of protists analyzed. The results are discussed within the framework of a number of published phyllogenies and shown to be in striking agreement with some of the schemes.","PeriodicalId":76288,"journal":{"name":"Origins of life","volume":"13 3-4","pages":"177-82"},"PeriodicalIF":0.0,"publicationDate":"1984-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF00927169","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"17267453","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}
