| paleoparasitological analysis of the extinct myotragus balearicus bate 1909 (artiodactyla, caprinae) from mallorca (balearic islands, western mediterranean). | myotragus balearicus (artiodactyla, caprinae) is an extinct caprine endemic of the eastern balearic islands or gymnesics (i.e., mallorca, menorca and surrounding islets, western mediterranean sea). in spite of its small size, c. 50cm height at the shoulder, it was the largest mammal inhabiting these islands until the human arrival, and it had peculiar short legs and frontal vision. it disappeared between 2830 and 2210calbce. the coprolites here studied were recovered from cova estreta, in pollen ... | 2017 | 27871871 |
| mitochondrial dna from myotragus balearicus, an extinct bovid from the balearic islands. | dna was extracted from teeth and bones of myotragus balearicus, a bovid that evolved in isolation on the balearic islands (western mediterranean) from the end of the miocene, becoming extinct 4,000 years bp, after the arrival of humans in the islands. the numerous morphological apomorphies of myotragus, most strikingly its dwarfism, frontal eyes, and ever-growing incisors, obscure its phylogenetic relationships with extant bovids. therefore, the recovery of genetic information from myotragus is ... | 2000 | 10750053 |
| evidence of correlated evolution of hypsodonty and exceptional longevity in endemic insular mammals. | here, we test whether the increase in tooth height in insular endemics results from the expansion of the dietary niche under resource limitation, as widely considered, or whether it represents an investment in dental durability in response to the selection for extended longevity under low levels of extrinsic mortality. we tested these hypotheses in the extremely hypsodont fossil bovid myotragus balearicus from the balearic islands, an ideal model to study the evolutionary trends on islands. dent ... | 2012 | 22535784 |

| a new african fossil caprin and a combined molecular and morphological bayesian phylogenetic analysis of caprini (mammalia: bovidae). | given that most species that have ever existed on earth are extinct, no evolutionary history can ever be complete without the inclusion of fossil taxa. bovids (antelopes and relatives) are one of the most diverse clades of large mammals alive today, with over a hundred living species and hundreds of documented fossil species. with the advent of molecular phylogenetics, major advances have been made in the phylogeny of this clade; however, there has been little attempt to integrate the fossil rec ... | 2012 | 22816969 |
| first fossil evidence for the advance of replacement teeth coupled with life history evolution along an anagenetic mammalian lineage. | in mammals that grow up more slowly and live longer, replacement teeth tend to appear earlier in sequence than in fast growing mammals. this trend, known as 'schultz's rule', is a useful tool for inferring life histories of fossil taxa. deviations from this rule, however, suggest that in addition to the pace of life history, ecological factors may also drive dental ontogeny. myotragus balearicus is an extinct insular caprine that has been proved to be an excellent test case to correlate morpholo ... | 2013 | 23936247 |
| Fragmentation of contaminant and endogenous DNA in ancient samples determined by shotgun sequencing; prospects for human palaeogenomics. | BACKGROUND: Despite the successful retrieval of genomes from past remains, the prospects for human palaeogenomics remain unclear because of the difficulty of distinguishing contaminant from endogenous DNA sequences. Previous sequence data generated on high-throughput sequencing platforms indicate that fragmentation of ancient DNA sequences is a characteristic trait primarily arising due to depurination processes that create abasic sites leading to DNA breaks. METHODOLOGY/PRINCIPALS FINDINGS: To ... | 2011 | 21904610 |
| paleogenomics in a temperate environment: shotgun sequencing from an extinct mediterranean caprine. | background: numerous endemic mammals, including dwarf elephants, goats, hippos and deers, evolved in isolation in the mediterranean islands during the pliocene and pleistocene. most of them subsequently became extinct during the holocene. recently developed high-throughput sequencing technologies could provide a unique tool for retrieving genomic data from these extinct species, making it possible to study their evolutionary history and the genetic bases underlying their particular, sometimes un ... | 2009 | 19461892 |
| molecular dating of caprines using ancient dna sequences of myotragus balearicus, an extinct endemic balearic mammal. | myotragus balearicus was an endemic bovid from the balearic islands (western mediterranean) that became extinct around 6,000-4,000 years ago. the myotragus evolutionary lineage became isolated in the islands most probably at the end of the messinian crisis, when the desiccation of the mediterranean ended, in a geological date established at 5.35 mya. thus, the sequences of myotragus could be very valuable for calibrating the mammalian mitochondrial dna clock and, in particular, the tree of the c ... | 2005 | 16332256 |
| molecular phylogeny and evolution of the extinct bovid myotragus balearicus. | myotragus balearicus was a dwarf artiodactyl endemic to the eastern balearic islands, where it evolved in isolation for more than 5 million years before becoming extinct between 3640 and 2135 cal bc (calibrated years bc). numerous unusual apomorphies obscure the relationship between myotragus and the extant caprinae. therefore, genetic data for this species would significantly contribute to the clarification of its taxonomic position. in this study, we amplify, sequence, and clone a 338-base pai ... | 2002 | 12450754 |
