The origins of complex, nucleated cellular life – everything from amoebas to humans – may date back a lot further in Earth's history than we thought. A new study tracing the earliest steps toward ...

Complex life began to develop earlier, and over a longer span of time, than previously believed, a new study has revealed. The research sheds new light on the conditions needed for early organisms to ...

Humans, as goofy and dumb as we can be at times, are actually seriously complicated creatures. We’re made from organs, bones and a strange, wrinkly body part called the brain that may or may not be ...

A new study uncovered fresh chemical evidence of life in rocks more than 3.3 billion years old, along with molecular traces showing that oxygen-producing photosynthesis emerged nearly a billion years ...

A 2.5-billion-year-old rock from South Africa's Gamohaan Formation. AI analysis suggests the dark structures preserved in the rock are the remains of a complex microbial community. Pairing ...

A machine-learning-enhanced approach to chemical analysis is drastically expanding the chemical record of life on Earth, and it could help us find evidence of life on other planets too. Reading time 3 ...

Researchers have discovered chemical traces of life in rocks older than 3.3 billion years, offering a rare look at Earth’s earliest biology. By combining advanced chemical methods with artificial ...

Earth's earliest life left behind very few chemical traces. Fragile remains, like ancient cells and microbial mats, were buried, squeezed, heated, and broken apart by the planet's shifting crust ...
