A chance discovery in 1938 by a South African museum curator unearthed a 'living fossil' – a coelacanth, a fish thought ...
A remarkable fish species, the Amazon molly, has defied evolutionary norms by surviving for 100,000 years without males.

The transition across the Cretaceous-Paleogene (K–Pg) boundary, approximately 66 million years ago, marks one of the most profound mass extinctions in Earth’s history, characterised by the demise of ...
Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but a new analysis extends the chart of life to nearly 2 billion years ago. The ...

The Cretaceous–Paleogene (K–Pg) mass extinction event, marking the boundary between the Cretaceous and Paleogene periods approximately 66 million years ago, stands as one of the most profound ...
Shortly after an asteroid slammed into Earth 66 million years ago, life for non-avian dinosaurs ended, but the evolutionary story for the early ancestors of birds began. The fossil record tells us ...
Last year, hiking in Morocco’s eastern Atlas Mountains, I found an ammonite, a fossil of those spiral-shape cephalopods that to many symbolize paleontology itself. The fossilization process had turned ...
Recent research showed that an artificially constructed RNA self-replicating system modeling primitive life at the origin of life evolved to become more prone to extinction under certain experimental ...
Life changes over time. Of course, it does. We know this thanks to a wealth of converging evidence in the form of millions of fossils, clear genetic clues, and observations made out in the field and ...
