Imagine zooming out on a giant family tree that includes every bird you have ever seen. Ostriches sprint across open plains, hummingbirds hover at flowers, penguins slice through cold seas, and eagles ...

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 ...

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 ...

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 ...

An analysis of millions of SARS-CoV-2 genomes finds that recombination of the virus is uncommon, but when it occurs, it is most often in the spike protein region, the area which allows the virus to ...

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 ...

Known as the "Queen of Climbers," the genus Clematis boasts over 300 species widely distributed across the globe. From tropical rainforests 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 ...

Scientists have found further evidence to support the idea that the primary two domains of life, the Archaea and Bacteria, are separated by a long phylogenetic tree branch and therefore distantly ...
