Because of the limited effectiveness of prevailing phylogenetic methods when applied to highly divergent protein sequences, the phylogenetic analysis problem remains challenging. Here, we propose a ...

Birds are the only dinosaur lineage that survived until today. About 66 million years ago at the Cretaceous–Paleogene (K–Pg) boundary, a mass extinction event destroyed all non-avian dinosaurs, ...

Phylogenetic tree analysis reconstructs the branching relationships among organisms or genes, revealing their shared ancestry and divergence over time. These tree structures are central to ...

Just as bird watchers may use binoculars to add to their species lists, scientists interested in bird evolution may use computational tools to clarify avian lineages. Indeed, such tools have enabled ...

A research team conducted a comprehensive analysis of phylogenetic relationships among Australian citrus species and 13 international accessions, shedding light on their genetic diversity and ...

The three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, according to a study in Nature Communications. It is the first time ...

New research headed by scientists at the Centre for Genomic Regulation (CRG) has demonstrated how the three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary ...

Birds are the most diverse land vertebrate on the planet, and now scientists have constructed a complete evolutionary tree of the 11,000 or so known species. This data came from hundreds of studies ...

This month, George Tiley began his NC State appointment as an assistant professor of plant and microbial biology. Right before his Aug. 1 start date, Tiley and colleagues published a Perspectives ...
