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 ...

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 ...

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 ...

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, ...

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 ...

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 ...

"This book was originally published as an issue of Philosophical transactions of the Royal Society B; Biological sciences (volume 363; number 1496) but has been materially changed and updated"--Title ...

Researchers used transcriptomics (a type of gene sequencing) calibrated using information from the fossil record to create the first phylogenetic reconstruction of the insect order Odonata ...

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 ...

There are extinctions, and then there’s the “Great Dying.” That was the Permian-Triassic extinction around 250 million years ago, which wiped out nearly all life on Earth. Scientists have been ...

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 ...
