Applying Islamic sources in Spain’s medieval histories: a case study of the Historia Arabum and Historia Gothica emphasizing the conquest of Andalusia and the life of Muhammad (PBUH)
Historia Gothica and Historia Arabum written by the Spanish prominent bishop, Rodrigo Jimenez de Rada, are of the most outstanding medieval historical works. Historia Arabum is the first Western work on Islamic history due to attention to Islamic history, which led to the importance of Rodrigo Jimenez among historians. The main question of the article is to what extent Islamic sources have infl...
متن کاملGoing to extremes: contrasting rates of diversification in a recent radiation of new world passerine birds.
Recent analyses suggest that a few major shifts in diversification rate may be enough to explain most of the disparity in diversity among vertebrate lineages. At least one significant increase in diversification rate appears to have occurred within the birds; however, several nested lineages within birds have been identified as hyperdiverse by different studies. A clade containing the finches a...
متن کاملDensity Dependence, Evolutionary Optimization, and the Diversification of Avian Life Histories*
Although we have learned much about avian life histories during the 50 years since the seminal publications of David Lack, Alexander Skutch, and Reginald Moreau, we still do not have adequate explanations for some of the basic patterns of variation in lifehistory traits among birds. In part, this reflects two consequences of the predominance of evolutionary ecology thinking during the past thre...
متن کاملA new time tree reveals Earth history's imprint on the evolution of modern birds.
Determining the timing of diversification of modern birds has been difficult. We combined DNA sequences of clock-like genes for most avian families with 130 fossil birds to generate a new time tree for Neornithes and investigated their biogeographic and diversification dynamics. We found that the most recent common ancestor of modern birds inhabited South America around 95 million years ago, bu...
متن کاملA latitudinal phylogeographic diversity gradient in birds
High tropical species diversity is often attributed to evolutionary dynamics over long timescales. It is possible, however, that latitudinal variation in diversification begins when divergence occurs within species. Phylogeographic data capture this initial stage of diversification in which populations become geographically isolated and begin to differentiate genetically. There is limited under...
