abstract = {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, but it was not until the Cretaceous-Paleogene transition (66 million years ago) that Neornithes began to diversify rapidly around the world. Birds used two main dis- persion routes: reaching the Old World through North America, and reaching Australia and Zealandia through Antarctica. Net diversification rates increased during periods of global cooling, suggesting that fragmentation of tropical biomes stimulated speciation. Thus, we found pervasive evidence that avian evolution has been influenced by plate tectonics and environmental change, two basic features of Earth?s dynamics.}

Birds Clocklike Exons |
first and second codon position of 1156 clock-like exons for 48 species from Jarvis et al (2014, Science 346), which we filtered for missing data (positions with missing data or gaps for any taxa were deleted) resulting in a final alignment of 124,196 bases. |
