The matrix of evolutionary distances is a model-based statistic, derived from molecular sequences, summarizing the pairwise phylogenetic relations between a collection of species. Phylogenetic tree reconstruction methods relying on this matrix are relatively fast and thus widely used in molecular systematics. However, because of their intrinsic reliance on summary statistics, distance-matrix me...

Multiple studies have been conducted in the last several years with the goal of understanding the evolution of genomes in the chordate lineage [1]. We used the two most recent ancestral genome reconstruction models by Nakatani et al. [2] and Putnam et al. [3] (therein referred to as “N” and “P” model respectively, see Figure 1 in main text) to clarify how the three rounds of whole genome duplic...

UNLABELLED • PREMISE OF THE STUDY The use of multiple genetic regions from the nuclear genome, including low-copy markers, has long been recognized as essential to robust phylogenetic construction, addressing gene tree incongruence, and allowing increased resolution to test current taxonomy and resolve basic hypotheses about character evolution, biogeography, and other organismal traits of in...

Abstract Background Lemurs once rivalled the diversity of rest primate order despite thier confinement to island Madagascar. We test adaptive radiation model Malagasy lemur using a novel combination phylogenetic comparative methods and geometric for quantifying tooth shape. Results apply macroevolutionary fitting approaches disparity through time analysis dental topography metrics associated wi...
