Researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split apart from the nautilus on ...

In a new study involving whole-genome data, researchers present “CASTER,” a tool that uses arrangements in DNA sequences known as site patterns to infer “species trees,” which are diagrams that depict ...

For decades, biologists have used evolutionary or phylogenetic trees to map how species and genes diverge from common ancestors. These trees are traditionally built by comparing DNA or protein ...

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 ...

Researchers at Hokkaido University have developed a new computational tool to help evolutionary biologists analyze complex genetic data to reconstruct the evolutionary history of species and the ...

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 ...
