Efficient construction of phylogenetic consensus trees. Methods include strict, majority-rule, majority-rule (+), loose (combinable component / semi-strict), greedy, Adams, frequency difference, R*, a...

In a discovery that challenges our understanding of dinosaur distribution during the Late Jurassic period, paleontologists have identified the first evidence of the iconic Diplodocus outside North Ame...

Adaptive radiations generate remarkable morphological diversity, yet traits often diversify at different rates and modes, producing mosaic patterns of evolution. Modularity, the semiautonomous organization of traits, can shape how selection and ...

Abstract. We investigate the predictability of evolution in terms of the phylogenetic placement of new lineages. This leads us to develop a class of coales
