A remarkable fish species, the Amazon molly, has defied evolutionary norms by surviving for 100,000 years without males.

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 ...

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 ...

Speciation and extinction are the twin engines that sculpt biodiversity over time. Speciation—the origin of new species—arises when populations become reproductively isolated and diverge through ...

I had occasion recently to listen to recordings of the actual calls and vocalizations of Rice’s whales. It was powerful. Will ...
