Phylogenetic trees describe the pattern of descent amongst a group of species. With the
rapid accumulation of DNA sequence data, more and more phylogenies are being …

Five decades have passed since the proposal of the molecular clock hypothesis, which
states that the rate of evolution at the molecular level is constant through time and among …

Zoonomia is the largest comparative genomics resource for mammals produced to date. By
aligning genomes for 240 species, we identify bases that, when mutated, are likely to affect …

The precise pattern and timing of speciation events that gave rise to all living placental
mammals remain controversial. We provide a comprehensive phylogenetic analysis of …

Despite tremendous efforts in the past decades, relationships among main avian lineages
remain heavily debated without a clear resolution. Discrepancies have been attributed to …

Although reconstruction of the phylogeny of living birds has progressed tremendously in the
last decade, the evolutionary history of Neoaves—a clade that encompasses nearly all living …

Previous analyses of relations, divergence times, and diversification patterns among extant
mammalian families have relied on supertree methods and local molecular clocks. We …

During the last ten years, remarkable progress has occurred in the study of molecular
evolution. Among the most important factors that are responsible for this progress are the …

Phylogenomic datasets have been successfully used to address questions involving
evolutionary relationships, patterns of genome structure, signatures of selection, and gene …

Successive adaptive radiations have played a pivotal role in the evolution of biological
diversity,,. The effects of adaptive radiation are often seen,,, but the underlying causes are …
