چکیده
Jarvis et al. (Research Articles, 12 December 2014, p. 1320) presented molecular clock analyses that suggested that most modern bird orders diverged just after the mass extinction event at the Cretaceous-Paleogene boundary (about 66 million years ago). We demonstrate that this conclusion results from the use of a single inappropriate maximum bound, which effectively precludes the Cretaceous diversification overwhelmingly supported by previous molecular studies.

AVIAN GENOMICS Response to Comment on “Whole-genome analyses resolve early branches in the tree of life of modern birds”
Mitchell et al. argue that divergence-time estimates for our avian phylogeny were too young because of an “inappropriate” maximum age constraint for the most recent common ancestor of modern birds and that, as a result, most modern bird orders diverged before the Cretaceous-Paleogene mass extinction event 66million years ago instead of after. However, their interpretations of the fossil record ...

متن کاملWhole-genome analyses resolve early branches in the tree of life of modern birds.
To better determine the history of modern birds, we performed a genome-scale phylogenetic analysis of 48 species representing all orders of Neoaves using phylogenomic methods created to handle genome-scale data. We recovered a highly resolved tree that confirms previously controversial sister or close relationships. We identified the first divergence in Neoaves, two groups we named Passerea and...
متن کاملCoalescent-Based Genome Analyses Resolve the Early Branches of the Euarchontoglires
Despite numerous large-scale phylogenomic studies, certain parts of the mammalian tree are extraordinarily difficult to resolve. We used the coding regions from 19 completely sequenced genomes to study the relationships within the super-clade Euarchontoglires (Primates, Rodentia, Lagomorpha, Dermoptera and Scandentia) because the placement of Scandentia within this clade is controversial. The d...

Since ancient times, “Tree” has been the focus of attention as a symbol, in works of art. In Mesopotamia and later in Iran, this symbol was known as a holy tree or tree of life as early as 3500 BC, and was delineated in different shapes. After the advent of Islam, this symbol prevailed in works of art; However, no longer as a mythological holy tree but rather standing for heavenly b...
