During the Pleistocene pygmy elephantids, some only a quarter of their ancestors' size, were present on Mediterranean islands until about 10,000 years ago (y.a.). Using a new methodology for ancient DNA (aDNA) studies, the whole genomic multiple displacement amplification method, we were able to retrieve cytochrome b (cytb) DNA fragments from 4200 to 800,000 y.a. specimens from island and mainl...
The B subunit is one of two nucleotide-binding polypeptides found in all members of the vacuolar class of H(+)-translocating ATPases. We have isolated aDNA clone encoding the bovine brain B (58 kDa) subunit and have deduced its amino acid sequence. The bovine brain amino acid sequence is 99% identical to a partial cDNA reported from human brain. Northern blot analysis of RNA isolated from bovin...
The performance of hybridization capture combined with next-generation sequencing (NGS) has seen limited investigation with samples from hot and arid regions until now. We applied hybridization capture and shotgun sequencing to recover DNA sequences from bone specimens of ancient-domestic dromedary (Camelus dromedarius) and its extinct ancestor, the wild dromedary from Jordan, Syria, Turkey and...
Since the late eighteenth century, fossils of bizarre extinct creatures have been described from the Americas, revealing a previously unimagined chapter in the history of mammals. The most bizarre of these are the 'native' South American ungulates thought to represent a group of mammals that evolved in relative isolation on South America, but with an uncertain affinity to any particular placent...
The Caspian tiger (Panthera tigris virgata) flourished in Central Asian riverine forest systems in a range disjunct from that of other tigers, but was driven to extinction in 1970 prior to a modern molecular evaluation. For over a century naturalists puzzled over the taxonomic validity, placement, and biogeographic origin of this enigmatic animal. Using ancient-DNA (aDNA) methodology, we genera...
The Basque population has been considered an outlier in a large number of genetic studies, due to its hypothesized antiquity and greater genetic isolation. The present paper deals with an analysis of the mtDNA variability of the historical population of Aldaieta (VI-VII c. AD; Basque Country) which, together with genetic data existing for other prehistoric populations of the Basque Country (4,5...
Human-mediated biological exchange has had global social and ecological impacts. In sub-Saharan Africa, several domestic and commensal animals were introduced from Asia in the pre-modern period; however, the timing and nature of these introductions remain contentious. One model supports introduction to the eastern African coast after the mid-first millennium CE, while another posits introductio...
Di era modern ini, jilbab memang sudah marak digunakan oleh kalangan muslimah baik anak-anak maupun dewasa. Tetapi yang menjadi problemnya, masih banyak wanita muslim memakai namun tidak sesuai dengan tuntunan syariat. Tujuan penelitian ini yaitu untuk mengungkapkan pandangan ulama kontemporer terhadap menutup aurat dan batasan-batasan perempuan. Metode dalam ialah kepustakaan (library research...
Abstract For decades, the relationship of pre-modern hominins to anatomically modern humans (AMH) and transition from mode 3 4 industries remain topics ongoing scientific debate. Over last 20 years, different disciplines have added new data much detail these questions, highlighting demographic social cultural complexity underlaying major changes or turnovers in human evolution. As with most oth...
Analysis of the incisor enamel microstructure extinct and extant West Indian caviomorph rodents emphasizes a clear microstructural distinction between Echimyidae (Capromyinae Heteropsomyinae) among Octodontoidea “Heptaxodontidae”, whose phylogenetic affinities are debated. All capromyines heteropsomyines have pattern characterized by rectangular crystallite arrangement, which is biomechanically...
