Gene tree and species tree reconciliation is a pivotal framework in evolutionary biology that bridges the evolutionary histories of individual gene families with the broader context of species ...

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 ...

The transition from water to land is a question that still intrigues scientists. Those ancient organisms would have needed to ...

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 ...

All life on Earth shares a common ancestor that lived roughly four billion years ago. This so-called “last universal common ancestor” represents the most ancient organism that researchers can study.

To understand how organisms are related, researchers use molecular information to construct phylogenetic trees. Most of the time, scientists use thousands of protein-coding sequences to determine ...

A new study led by researchers at Penn State has uncovered several instances of wood warblers — like the Magnolia Warbler pictured here — passing color-related genes to other species of wood warblers, ...

Esvelt’s entanglement with evolution began early. As a child, he visited the Galápagos, and was captivated by the islands’ stunning array of unique wildlife. “That sparked an interest in the evolution ...

The teeth are from Paranthropus robustus, an extinct hominin genus that emerged and evolved in Africa between 2.8 and 1.2 Ma. It is considered to be a side branch of our evolutionary tree. It walked ...

This month, George Tiley began his NC State appointment as an assistant professor of plant and microbial biology. Right before his Aug. 1 start date, Tiley and colleagues published a Perspectives ...
