متن کاملDiscoVista: Interpretable visualizations of gene tree discordance.
Phylogenomics has ushered in an age of discordance. Analyses often reveal abundant discordances among phylogenies of different parts of genomes, as well as incongruences between species trees obtained using different methods or data partitions. Researchers are often left trying to make sense of such incongruences. Interpretive ways of measuring and visualizing discordance are needed, both among...
متن کاملSpider phylogenomics: untangling the Spider Tree of Life
Spiders (Order Araneae) are massively abundant generalist arthropod predators that are found in nearly every ecosystem on the planet and have persisted for over 380 million years. Spiders have long served as evolutionary models for studying complex mating and web spinning behaviors, key innovation and adaptive radiation hypotheses, and have been inspiration for important theories like sexual se...
متن کاملIs The Amphibian Tree of Life really fatally flawed?
Wiens (2007, Q. Rev. Biol. 82, 55–56) recently published a severe critique of Frost et al.’s (2006, Bull. Am. Mus. Nat. Hist. 297, 1–370) monographic study of amphibian systematics, concluding that it is ‘‘a disaster’’ and recommending that readers ‘‘simply ignore this study’’. Beyond the hyperbole, Wiens raised four general objections that he regarded as ‘‘fatal flaws’’: (1) the sampling desig...
متن کاملGene tree discordance, phylogenetic inference and the multispecies coalescent.
The field of phylogenetics is entering a new era in which trees of historical relationships between species are increasingly inferred from multilocus and genomic data. A major challenge for incorporating such large amounts of data into inference of species trees is that conflicting genealogical histories often exist in different genes throughout the genome. Recent advances in genealogical model...
