Living organisms share an ancestor called the last universal common ancestor, or LUCA. LUCA is estimated to have lived ...

A new study used mathematical formulas and demonstrated that it’s highly unlikely life began on Earth. Instead, the researcher points to panspermia, a theory that life or the ingredients for life came ...

The impact of the asteroid 66 million years ago did not stop life from returning to normal for very long. New research shows that life, particularly marine life, recovered much more quickly than ...

The harsh conditions of Mono Lake—including its salty waters and the presence of toxins like arsenic and cyanide—may have played a key role in shaping the evolution of this unusual species. (CREDIT: ...

Assembly Theory is a way to understand how the complexity of life emerged through a mechanism of “self-assembly.” It could explain how life formed on Earth—or other planets—via the shortest path to ...

A biochemist, building on the pillars of evolutionary theory and drawing on cutting-edge research into the link between energy and genes, argues that the evolution of multicellular life was the result ...
