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 ...

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 ...

A research team conducted a comprehensive analysis of phylogenetic relationships among Australian citrus species and 13 international accessions, shedding light on their genetic diversity and ...

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, ...

In evolutionary biology, all life on Earth is theoretically part of a single phylogenetic tree, indicating common ancestry.

The three-dimensional shape of a protein can be used to resolve deep, ancient evolutionary relationships in the tree of life, according to a study in Nature Communications. It is the first time ...

Read me first! -- Tutorial : create a tree! -- Acquiring and aligning the sequences -- pt. 1. Major methods for estimating phylogenetic trees. Neighbor-joining trees -- Drawing phylogenetic trees -- ...

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 ...

Blood cells carry a deep evolutionary history. A new analysis suggests their earliest ancestors were macrophage-like cells ...
