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 ...

Animal life began in aquatic environments more than 600 million years ago. Around 500 million years ago, during the Cambrian ...

Scientists have discovered a hidden partnership between ancient microbes that may explain how complex life first evolved on ...

Living organisms share an ancestor called the last universal common ancestor, or LUCA. LUCA is estimated to have lived approximately four billion years ago. All plants, animals, and microbes can trace ...

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 ...

Here is what you’ll learn in this story: Panspermia is the controversial theory that life evolved elsewhere in the universe and—some way or another—made it here, where it developed into the diversity ...

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 ...
