Ancient duplicated genes are giving scientists their first real clues about what life was like before all life on Earth shared a common ancestor.

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

A new wave of scientists argues that mainstream evolutionary theory needs an urgent overhaul. Their opponents have dismissed them as misguided careerists – and the conflict may determine the future of ...

Scientists have uncovered an unexpected genetic shift that may explain how animals with backbones first emerged and became so diverse.

Evolutionary biology explores how living systems change over time through variation, inheritance and differential success. At its heart lies the concept of descent with modification: populations ...

Harvard Faculty of Arts and Sciences has officially voted to change the name of the Human Evolutionary Biology concentration during a meeting on April 1. Effective as of July 1, 2025 — when the ...

Research study reports intriguing findings made through innovative artificial intelligence analysis about yeasts -- small fungi that are key contributors to biotechnology, food production, and human ...

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 ...

Scientists have developed a theoretical model that uncovers the dual role of polyploidy -- organisms carrying extra genome copies -- in evolution. Their findings reveal that polyploidy can stabilize ...
