Extreme climate, rather than population history, explains mid-facial morphology of Northern Asians
No full textPrevious studies have examined mid-facial cold adaptation among either widely dispersed and genetically very diverse groups of humans isolated for tens of thousands of years, or among very closely related groups spread over climatically different regions. Here we present a study of one East Asian and seven North Asian populations in which we examine the evidence for convergent adaptations of the mid-face to a very cold climate. Our findings indicate that mid-facial morphology is strongly associated with climatic variables that contrast the temperate climate of East Asians and the very cold and dry climate of North Asians. This is also the case when either maxillary or nasal cavity measurements are considered alone. The association remains significant when mtDNA distances among populations are taken into account. The morphological contrasts between populations are consistent with physiological predictions and prior studies of mid-facial cold adaptation in more temperate regions, but among North Asians there appear to be some previously undescribed morphological features that might be considered as adaptive to extreme cold. To investigate this further, analyses of the seven North Asian populations alone suggest that mid-facial morphology remains strongly associated with climate, particularly winter precipitation, contrasting coastal Arctic and continental climates. However, the residual covariation among North Asian mid-facial morphology and climate when genetic distances are considered, is not significant. These findings point to modern adaptations to extreme climate that might be relevant to our understanding of the mid-facial morphology of fossil hominins that lived during glaciations
Vsevolod Garshin’s Dialogue with History: Notes on Vasily Surikov’s "Boyarynya Morozova"
Get PDFThe author of the article analyzes a review by the Russian writer and critic Vsevolod Garshin for his perception of Vasily Surikov’s painting Boyarynya Morozova. In the eyes of Garshin Morozova, an apologist of the Old Rite, is an irrational fanatic, sacrificing her life for mere phantoms. Garshin judges Morozova’s martyrdom in a very emotional and subjective way and does not understand the cultural and historic meaning of the act. The personal nature of Garshin’s dialogue with history is emphasized in the article

Revision of the suborder Fenestelloidea
No full textBased on the budding patterns present in Paleozoic fenestrate bryozoans, we propose a revision of the suborder Fenestelloidea Astrova and Morozova, 1956, to include four families : Fenestellidae King, 1849, Polyporidae Waagen and Pichl, 1885, Septopidae Morozova, 1962 and Fenestraliidae Morozova, 1963. The family Phylloporinidae Ulrich, 1890, is removed from the Fenestelloidea because of different zooecial shape, presence of specific heterozoids and the absence of ovicells.
The geographically widespread families of Fenestellidae and Polyporidae contain genera that evolved similar forms along parallel lines during the Paleozoic. These similar genera have been grouped into eight subfamilies, four of which are new, within their respective families. Examples of this parallel development for Fenestellidae and Polyporidae are : Fenestellinae Waagen and Pichl, 1885 - Polyporinae Waageng & Pichl, 1885 ; Diploporinae Vine, 1884 - Acanthocladiinae Zittel, 1880.
The specific budding patterns that characterize the septoporids and fenestraliids and their restricted development in the Late Paleozoic confirm the separate phylogenetic development of these families.
The revised diagnosis of the suborder Fenestelloidea and the diagnosis and generic composition of the families and subfamilies proposed in this revision are given.En nous basant sur les différentes sortes de bourgeonnement chez les bryozoaires fenestrés paléozoïques, nous proposons une révision du sous-ordre Fenestelloidea Astrova et Morozova, 1956, comme renfermant quatre familles : Fenestellidae King, 1849 ; Polyporidae Waagen et Pichl, 1885 ; Septoporidae Morozova 1962 et Fenestraliidae Morozova, 1963. La famille Phylloporinidae Ulrich, 1890 est exclue de Fenestelloidea à cause d'autre forme des zoécies, de présence d'hétérozoécies spécifiques et d'absence d'ovicelles.
Les familles géographiquement répandues de Fenestellidae et Polyporidae contiennent les genres qui développaient des formes semblables pendant le Paléozoïque. On peut grouper ces genres en six sous-familles, dont deux sont nouvelles. Des exemples de ce développement parallèle sont : Fenestellinae Waagen et Pichl, 1885 - Polyporinae Waagen et Pichl, 1885 ; Diploporinae Vine, 1884 - Acanthocladiinae Zittel, 1880.
Le bourgeonnement spécifique des Septoporidae et Fenestraliidae et leur développement limité au Paléozoïque supérieur confirment la phylogénie particulière de ces familles.
On donne les diagnoses révisées du sous-ordre Fenestelloidea, les diagnoses et la composition générale des familles et sous-familles proposées dans cette révision.Dunaeva N. N., Morozova I. P.
