Group Selection Was Debated For Decades. A New Review Says The Empirical Case Is Far Stronger Than Critics Claimed. In A Nutshell A new review of nearly 3,000 scientific papers found 280 studies ...

Human newborns arrive remarkably underdeveloped. The reason lies in a deep evolutionary trade-off between big brains, bipedalism and the limits of motherhood.

Life’s story may stretch further back than scientists once thought. Some genes found in nearly every organism today were already duplicated before all life shared a common ancestor. By tracking these ...

Charles Darwin’s theory of evolution by natural selection transformed biology and continues to guide modern science, from ...

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

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 ...

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 ...

We humans have long viewed ourselves as the pinnacle of evolution. People label other species as “primitive” or “ancient” and ...

The study of early vertebrates provides an essential window into the evolutionary processes that shaped modern biodiversity. Fossil discoveries spanning the Silurian to Devonian periods reveal a ...

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 ...

In this computer simulation of a self-replicating structure, the pink square represents the signal to degrade the connection between the "parent" structure (left) and its "offspring" (right). This ...

Researchers at the University of Michigan have developed a modular, open-source robot that can ...
