An artist’s impression depicts Kryoryctes at Dinosaur Cove in Australia. New research supports the hypothesis that Kryoryctes is a common ancestor of both the platypus and echidna. - Peter Schouten ...

Biologists are closing in on a puzzle that seems to turn classic evolutionary logic inside out, yet may be so common that it ...

The Cambrian Explosion in which life on Earth underwent massive diversification was likely triggered by eccentricities in Earth’s orbit around our Sun. Or so say the authors of a new paper just ...

A landmark study into the geological timescale distribution of sediment and nutrients over 500 million years shows that species biodiversity on Earth is driven by landscape dynamics. Movement of ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...

Researchers have laid out the case for complex life evolving 2.1 billion years ago, but not everyone is convinced it started so early. When you purchase through links on our site, we may earn an ...

What would you contribute to the world of ecology and evolution if you could access the combined wisdom of faculty from more than a dozen disciplines that span the earth, biological and computational ...

Top panel shows reconstructed sediment fluxes to the oceans vs diversity of marine animals. Bottom panel shows sediment cover in continental regions vs the long-term trend in land-plant diversity.
