Living organisms share an ancestor called the last universal common ancestor, or LUCA. LUCA is estimated to have lived ...

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 ...

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

All species alive today, from chimpanzees to bacteria, are cousins that each have equally long lineages, rather than ...

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 ...

Study finds that the mass extinction caused by an asteroid about 66 million years ago led to critical changes in bird genomes that ultimately sparked the incredibly diversity living birds. Shortly ...

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 ...

Researchers have described proteins that they say are among the most ancient ever sequenced. Two teams, which analysed molecules from extinct relatives of rhinos and other large mammals, have pushed ...

All life on Earth shares a common ancestor that lived roughly four billion years ago. This so-called "last universal common ancestor" represents the ...
