The Cornell Lab of Ornithology today announced the release of a new online tool for studying biodiversity and the ...
Progress and perspectives of the deep non-bilaterian phylogeny, with focus on sponges (Phylum Porifera) / Gert Wörheide, Tetyana Nosenko, Fabian Schreiber, and Burkhard Morgenstern -- Phylogenetics ...
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 ...
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 ...
The new model focuses on phylogenetic diversity, which is very different from counting species, today's standard measure of biodiversity. The same number of species (three blue circles) can have 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, ...
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 ...
As of June 16, 2022, there were 10,594,265 sequences displayed in the UShER COVID-19 phylogenetic tree. 10 million sequences of COVID-19’s genomic code have now been organized into a phylogenetic tree ...
