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 analysis underpins modern evolutionary biology by constructing trees that illustrate the relationships among species and genes. Gene tree reconciliation extends these analyses by aligning ...

Biologists will be able to reconstruct the process of evolution, determine relationships between species and build phylogenetic trees with greater accuracy thanks to a new method for identifying ...

Tree thinking is a pedagogical approach that emphasises the interpretation and construction of phylogenetic trees to elucidate evolutionary relationships. In the context of evolutionary biology ...

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 ...
