This semi-aquatic mammal may look improbable, but its biology reveals how evolution shapes even the strangest mammal bodies.

A new paper in Molecular Biology and Evolution, finds that changes in animal development induced by climate shock persist ...

For decades, many evolutionary biologists argued that natural selection acts primarily on individuals. In other words, that organisms are rewarded or penalized one at a time, and that the idea of ...

The Cromwell Harbor Foundation named two early-career scholars of extraordinary promise as the inaugural recipients of their Chrysalis Prize, awarding each scholar $250,000 in unrestricted support, ...

As our evolution slows and industrialization and technology accelerates, a growing body of research suggests that human biology is struggling to keep pace. Many of the chronic stress-related health ...

Scientists have long tried to decode every dream we have. Some say it’s survival training, others say it’s memory at work, ...

Frequent burn exposure may have driven human genetic adaptations that improve healing but worsen severe injury outcomes.

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 chance discovery in a Vermont cheese cave has given scientists a rare glimpse of evolution unfolding in real time – and the unexpected findings have broad implications for protecting human health, ...

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 ...

The human ability to cook may seem ordinary, but it marks one of the most important evolutionary turning points in our ...
