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 ...

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 ...

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, ...

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 ...

In 2014 the Science journal featured an article on the bird tree of life, mentioning the essential role of algorithms and supercomputers that enable modern research in evolutionary biology for all ...

The branching structure of biological evolution confers statistical dependencies on phenotypic trait values in related organisms. For this reason, comparative macroevolutionary studies usually begin ...

New research led by scientists at the Milner Centre for Evolution at the University of Bath suggests that determining evolutionary trees of organisms by comparing anatomy rather than gene sequences is ...

Hymenonema (Compositae, tribe Cichorieae) together with the genera Catananche, Gundelia, and Scolymus forms the subtribe Scolyminae. It is endemic to Greece and consists of two species, Hymenonema ...

The story of primates is a tale of incredible variety and ancient roots, told through the lens of science, DNA, and time itself. These creatures, ranging from massive gorillas to tiny mouse lemurs, ...

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and severe acute respiratory syndrome coronavirus (SARS-CoV) are members of the subgenus Sarbecovirus, whose genomic length is around ...
