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 ...

Life on Earth began simply. For billions of years, tiny microbes ruled the planet. Then, one day in deep time, something changed. Cells gained a nucleus, built inner compartments and learned to ...

Approximately four billion years ago, the first forms of life emerged on Earth. For eons, biological life consisted of prokaryotic organisms, either early bacteria or archaea. Determining when ...

The team has proposed a new evidence-based scenario for the emergence of complex life they have called ‘CALM’ - Complex Archaeon, Late Mitochondrion. Complex life began to develop earlier, and over a ...
