Although central to phylogenetics, the concept of clade is paradoxical since it has been ambiguously understood or even misunderstood by its own promoters. Writings by Ernst Haeckel, Lucien Cuénot, and Julian Huxley, the three authors who discussed the notion of clade at length, are analyzed here in detail as a means of exploring this paradox. First conceived as a rank for a higher-level category, and later as a taxon, the clade is understood today in connection with Hennig's definition of a monophyletic group rather than through Huxley's successful but somehow ambiguous formalization. The inability of these authors to formulate a clear-cut exposition of the concept is considered here within three contexts: firstly, the burden of pre-Darwinian classifications based on similarity; secondly, the underestimation of Darwin's description of a genealogical group; and thirdly, the predominance of thinking in process (vs thinking in pattern), which was the basis of evolutionary systematics in the mid-twentieth century.","PeriodicalId":54428,"journal":{"name":"Theory in Biosciences","volume":"140 1","pages":"77-85"},"PeriodicalIF":1.1,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s12064-020-00326-2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38522349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A little later it turned out that this proposal unfortunately does not correspond to biological reality. However, in the mid-90s, a weaker version of comma-free codes, so-called circular codes, was discovered in nature in J Theor Biol 182:45-58, 1996. Circular codes allow to retrieve the reading frame during the translational process in the ribosome and surprisingly the circular code discovered in nature is even circular in all three possible reading-frames ([Formula: see text]-property). Moreover, it is maximal in the sense that it contains 20 codons and is self-complementary which means that it consists of pairs of codons and corresponding anticodons. In further investigations, it was found that there are exactly 216 codes that have the same strong properties as the originally found code from J Theor Biol 182:45-58. Using an algebraic approach, it was shown in J Math Biol, 2004 that the class of 216 maximal self-complementary [Formula: see text]-codes can be partitioned into 27 equally sized equivalence classes by the action of a transformation group [Formula: see text] which is isomorphic to the dihedral group. Here, we extend the above findings to circular codes over a finite alphabet of even cardinality [Formula: see text] for [Formula: see text]. We describe the corresponding group [Formula: see text] using matrices and we investigate what classes of circular codes are split into equally sized equivalence classes under the natural equivalence relation induced by [Formula: see text]. Surprisingly, this is not always the case. All results and constructions are illustrated by examples.","PeriodicalId":54428,"journal":{"name":"Theory in Biosciences","volume":"140 1","pages":"107-121"},"PeriodicalIF":1.1,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s12064-020-00337-z","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"25318410","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These furrows were first described by Prévost and Dumas (Ann Sci Nat 2:100-121, 129-149, 1824b) who did not realize they cut the egg into separate masses. Rusconi (Développement de la grenouille comune depuis le moment de sa naissance jusque a son état parfait, Giusti, Milano, 1826) hypothesized a connection between the furrows and a peculiar crystallization of the content of the egg which eventually produced elementary molecules as the building blocks of the embryo. von Baer (Arch Anat Phys Wiss Med 6:481-509, 1834) was the first to establish a link between the furrows and an active process of dichotomous division he considered to be the basis for all further development and differentiation. The present paper analyses the theoretical reasons behind these divergent interpretations and focuses attention on their implications for the development of the cell theory and the conceptions of life. Prévost, Dumas and Rusconi interpreted cleavage and the whole embryonic development in the light of eighteenth-century scientific theories and the French materialism of the early nineteenth century, which explained life in terms of ordered molecular movement. Starting from other premises partly rooted in German philosophy von Baer (1834) gave a totally different picture which anticipated the cell theory and modern embryology.","PeriodicalId":54428,"journal":{"name":"Theory in Biosciences","volume":"140 1","pages":"45-75"},"PeriodicalIF":1.1,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s12064-020-00325-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38668585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In his texts (mainly the Historia animalium), Aristotle is often referring to the drawings after the description of species. Our study applies the method of the comparative view ('Vergleichendes Sehen') to provide an access to and reconstruction of Aristotle's lost illustrations based on his textual descriptions. As an example, we chose the treatment of the European lobster (Homarus gammarus L., 1758) in the Aristotelian corpus as a case study. First, we analyse the etymology of the Greek term astakós referring to the lobster and provide an overview on the putative synonyms. Second, we confront the textual basis of the description with several questions concerning the degree of abstraction, the relation between text and image, and the spatial orientation of the image. Finally, we present a step-by-step reconstruction of Aristotle's illustrations of the lobster based on the various passages dealing with its anatomy in the text of the Historia animalium. The problems which arise by a confrontation of the textual basis with hypothetical images are discussed at a more general level. We conclude that this kind of a text-based image reconstruction is only possible if the object described by Aristotle is unambiguously identifiable and still visually accessible.","PeriodicalId":54428,"journal":{"name":"Theory in Biosciences","volume":"140 1","pages":"1-15"},"PeriodicalIF":1.1,"publicationDate":"2021-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s12064-020-00322-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38481662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
