Phenotypic variations allow a lineage to move into new regions of the adaptive landscape. The purpose of this study is to analyse the life history of the pearlfishes (Carapinae) in a phylogenetic framework and particularly to highlight the evolution of parasite and commensal ways of life. Furthermore, we investigate the skull anatomy of parasites and commensals and discuss the developmental process that would explain the passage from one form to the other. The genusCarapusforms a paraphyletic grouping in contrast to the genusEncheliophis, which forms a monophyletic cluster. The combination of phylogenetic, morphologic and ontogenetic data clearly indicates that parasitic species derive from commensal species and do not constitute an iterative evolution from free-living forms. Although the head morphology ofCarapusspecies differs completely fromEncheliophis,C. homeiis the sister group of the parasites. Interestingly, morphological characteristics allowing the establishment of the relation betweenCarapus homeiandEncheliophisspp. concern the sound-producing mechanism, which can explain the diversification of the taxon but not the acquisition of the parasite morphotype.Carapus homeialready has the sound-producing mechanism typically found in the parasite form but still has a commensal way of life and the corresponding head structure. Moreover, comparisons between the larval and adult Carapini highlight that the adult morphotype “Encheliophis” is obtained by going beyond the adult stage reached byCarapus. The entrance into the new adaptive landscape could have been realised by at least two processes: paedomorphosis and allometric repatterning.

AbstractReconstructing patterns of macroevolution has become a central endeavor in paleobiology, because it offers insight into evolutionary models shaping the history of life. As the most diverse and abundant animals since the Cambrian period, arthropods provide copious data to elucidate the emergence of body plans in metazoan lineages. However, information provided by fossils on the tempo and mode of this phenomenon has lacked a recent synthesis. Here, I investigate macroevolutionary patterns of morphological evolution in Euarthropoda using a combined extinct and extant dataset optimized for multivariate analyses. Overall ordination patterns between the main morphogroups are consistent with another, independently coded, extant-only dataset providing molecular and morphological rates of evolution. Based on a “deep split” phylogenetic framework, total-group Mandibulata and Arachnomorpha emerge as directional morphoanatomical lineages, with basal fossil morphogroups showing heterogeneously spread-out occupations of the morphospace. In addition to a more homogeneous morphological variation, new morphogroups arose by successive reductions of translation distances; this pattern was interrupted only by terrestrialization events and the origin of pancrustaceans. A displaced optimum type of model is proposed to explain the fast assembly of canalized body plans during the Cambrian, with basal fossil morphogroups fitting intermediate fitness peaks in a moving adaptive landscape. Given time constraints imposed by the paleontological evidence, and owing to the interplay between canalization and modularity, as well as a decoupling between molecular and morphological rates, the rise of euarthropods would support the view that the swiftness of the Cambrian explosion was mostly associated with the buildup of genetic regulatory networks.

AbstractThis article re-examines our understanding of modern sport. Today, various physical cultures across the world are practised under the name of sport. Almost all of these sports originated in the West and expanded to the rest of the world. However, the history of judo confounds the diffusionist model. Towards the end of the nineteenth century, a Japanese educationalist amalgamated different martial arts and established judo not as a sport but as ‘a way of life’. Today it is practised globally as an Olympic sport. Focusing on the changes in its rules during this period, this article demonstrates that the globalization of judo was accompanied by a constant evolution of its character. The overall ‘sportification’ of judo took place not as a diffusion but as a convergence – a point that is pertinent to the understanding of the global sportification of physical cultures, and also the standardization of cultures in modern times.

How should we look back on the history and the origins of our ethical outlook and our way of life? We know that in the past, strange and appalling ethical views and practices have enjoyed widespread and sincere support. Yet we do not regard our contemporary outlook – to the extent that we do, at the present, have a common outlook – as one option among many. However bemused we may feel in ethical matters, at least on some issues we claim to have reasons that are good (enough). If we do not object to the use of the predicate ‘true’ in ethics, we may say that we are confronted with the (ethical) truth of an outlook. Or, to echo a provocative expression of David Wiggins, we claim that ‘there is nothing else to think’.

Physarieae is a small tribe of herbaceous annual and woody perennial mustards that are mostly endemic to North America, with its members including a large amount of variation in floral, fruit, and chromosomal variation. Building on a previous study of Physarieae based on morphology and ndhF plastid DNA, we reconstructed the evolutionary history of the tribe using new sequence data from two nuclear markers, and compared the new topologies against previously published cpDNA-based phylogenetic hypotheses. The novel analyses included ca. 420 new sequences of ITS and LUMINIDEPENDENS (LD) markers for 39 and 47 species, respectively, with sampling accounting for all seven genera of Physarieae, including nomenclatural type species, and 11 outgroup taxa. Maximum parsimony, maximum likelihood, and Bayesian analyses showed that these additional markers were largely consistent with the previous ndhF data that supported the monophyly of Physarieae and resolved two major clades within the tribe, i.e., DDNLS (Dithyrea, Dimorphocarpa, Nerisyrenia, Lyrocarpa, and Synthlipsis)and PP (Paysonia and Physaria). New analyses also increased internal resolution for some closely related species and lineages within both clades. The monophyly of Dithyrea and the sister relationship of Paysonia to Physaria was consistent in all trees, with the sister relationship of Nerisyrenia to Lyrocarpa supported by ndhF and ITS, and the positions of Dimorphocarpa and Synthlipsis shifted within the DDNLS Clade depending on the employed data set. Finally, using the strong, new phylogenetic framework of combined cpDNA + nDNA data, we discussed standing hypotheses of trichome evolution in the tribe suggested by ndhF.

AbstractThe use of different methodological approaches together with an exhaustive qualitative study has helped to recognize important morphological traits to distinguish species in a systematic and phylogenetic framework.Parabolinella triarthroidesHarrington, 1938 was described based on two cranidia from the Quebrada de Coquena, Purmamarca, Jujuy province. The generic assignment ofP. triarthroideshas been questioned by a phylogenetic analysis, which resolves this species as the sister group ofBienvilliaClark, 1924. To explore the generic assignment of this species, a revision of the type material, plus a morphometric analysis including specimens ofParabolinellaBrøgger, 1882 andBienvilliawere performed. In addition, the original matrix used in the published phylogeny was reviewed and enlarged, including more species ofBienvillia. Continuous characters were coded in different ways in order to compare how they could affect the ordering of specimens and their phylogenetic relationships. Finally, both methodologies were compared, especially in regard to the behavior of the quantitative characters included in the analyses. From the combined analyses, it is shown that similarities between the cranidium ofP. triarthroidesand all otherParabolinellaspecies are true homologies instead of a by-product of evolutionary convergence. Therefore,P. triarthroidesshould be considered a member of this genus. Finally, this study demonstrates that the best strategy for solving systematic problems in groups where the morphological variation is the only source of information (i.e., fossil taxa without living representatives) is the implementation of an integrative approach, combining different methodological techniques and a good description of specimens.

Seed rainfall may be one of the mechanisms most impacted by livestock production in forest remnants. The trampling and cattle grazing alter dynamics, structure and floristic composition of the forest. The present work characterized the seed rainin forest remnants and the possible impacts of the presence and the management regime with different cattle stocks in the Pampa biome, southern region of Brazil. We compared three areas in Seasonal Forest remnants with a management history of 43 years: cattle exclusion area (A1); area with a cattle stock of 0.5 ua ha-1 (A2); and area with cattle stock of 1.0 ua ha-1 (A3). The seed rain was collected quarterly in 16 collectors (1 × 1 m²) per area for 24 months. The seeds were counted and identified according to external morphological characteristics, habit and dispersion syndrome. Shannon diversity index, submitted to the Hutcheson test, Pielou evenness, expected diversity and floristic similarity were determined. The results indicated that the impacts caused by livestock to seed rain were more significant in A3 where a quantitative reduction in the number of seeds was observed, probably due to the low number of plant individuals that make up the community.

Semantic Scope

The bishop of Brescia, Philastrius, author of the first Latin catalogue of he­resies, written between 380 and 388, presented in his treaty an extremely large number of heterodox movements: 28 within Judaism and 128 in early Christianity. This comes as a result of a wide understanding of the term heresis. For Philastrius this term was synonymous with the term error, recognized as any deviation from the universal truth in the history of the world, inspired by Satan as “the father of lies”, ocurring primarily in Judaism and Christianity. Among the early Christian views defined by the bishop of Brescia as heresy five groups can be distinguished. The first group includes mainly the erroneous views on fundamental theological questions contained in the rule of faith, such as the concept of a creator God and saviour Jesus Christ. The second set of he­resies, closely related with the previous one, contains the erroneous doctrines of anthropology, such as questioning the resurrection of the human body or the view of the materiality of the human soul. The third group includes the views related to the misinterpretation of Scripture, especially exaggerated literal interpretations of the texts of the Old Testament, as well as the cosmological views which do not agree with descriptions contained within the Bible. The fourth group contains the moral issues related to the based on laxism or rigorism way of life, as well as to the attitude of lack of deference to the laws of the Church, but non-threatening the primary truths of the Christian faith. The fifth group of heresies includes the movements defined by the authors of the late patristic period as a schizm, while the term schisma is not at all used by the bishop of Brescia in his work. The semantic scope of the term heresis in Philastrius’ treaty went beyond the noncompliance with the regula fidei. According to the bishop of Brescia each offense – whether in doctrinal teaching or practice of life, as well as with regard to the understanding of the text of Scripture – is a heresy because it offends God and the Church. Therefore, in Philastrius opinion one should not differentiate between superior and minor error, but equally condemn them as attitudes directed against God as the Father of Truth.

The author considers the content of the “Milan Papyrus” with the epigrams of Posidippus of Pella, the first edition of which was published in 2003, with reference to the history of the Nabataean Arabs. The mention of the Nabataean king in the work is the very first in narrative sources, which allows to reconsider some traditional points of view on the life of the Nabataeans in the early Hellenistic period before their transition to a settled life. It should be noted that referring to the early period of the history of the Nabataeans, researchers inevitably encounter a problem that is associated with a lack of narrative sources. The data available today do not fully restore the course of historical events, especially during the period when the Nabataean tribes led a nomadic lifestyle. To a certain extent, the fragmentariness of the written sources is compensated by the data of archeology, epigraphy and numismatics, however, the early Hellenistic period of the history of the Nabataeans, unfortunately, is still not adequately covered by the sources. Meanwhile, it was at that time when the Nabataeans experienced a gradual transition from a nomadic way of life to a sedentary one, as well as the most important historical processes that determined the path of their further existence under statehood were being held. Nevertheless, the range of sources is gradually expanding, which allows researchers to set new tasks and look for ways to solve them. Thus, as a result of the research, the author concludes that the data of the “Milan Papyrus” suggest that the royal Nabataean dynasty has deeper roots than was commonly believed, and from the middle of the third century BC at the head was the king, under whose command was the cavalry corps. This conclusion changes the generally accepted idea of the socio-political development of the Nabataean society in the early stages of its history.

The key concept of our study is "religiosity". In scientific literature, it is most often correlated with an individual or a social group, a community and understands a set of certain attributes that are inherent to them and which find expression in faith and worship of supernatural both at the level of consciousness and at the level of behavior. The object of our study is the Ukrainian people (ethnos). It should be noted that religious studies in Soviet times did not take into account the fact that human existence is possible only in the conditions of a certain ethnic community, an individual is, above all, a certain ethnotype, and, moreover, it does not study the religious dimensions of the ethno-national being of that another people. Religion itself, if considered as a special, long-standing state of consciousness, as a certain system, which is a set of elements (ideas, representations) that interact with each other and with the environment, form a stable integrity, can be considered an integral part of ethno-national mentality. According to M.Kostomarov, folk religiosity is a special view that the people have in their religion and that it does not constitute any kind of whole religion, nor a certain sect. Today it is universally accepted that the national type of religiosity exists on the ordinary level of consciousness, is a complex syncretic entity. The history of its formation does not coincide with the history of the doctrine of a certain denomination. However, it is clear that the religiosity of Ukrainians, posing an integral part of the mentality and spirituality of the people, has a history of its formation. It is a consequence of the influence of a complex of factors that predetermined the way of life of the Ukrainian people in a certain natural geographic and cultural-historical space.
