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 ...

A team led by researchers at the University of Texas at Austin has produced what may be the strongest evidence yet that the ancient ancestors of all complex life on Earth already had the genes to use ...

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 ...

In a blow to anyone dreaming that complex life may exist elsewhere in the universe, a new study suggests we're unlikely to find it around many of the most common stars in the galaxy. Earth-like ...

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 ...

On the shores of the west coast of Australia lies a window to our past: the stromatolites and microbial mats of Gathaagudu (Shark Bay). To the untrained eye they look like a collection of rocks and ...

The research led by the University of Bristol was published in the scientific journal Nature 3 December, the research indicates that complex organisms evolved long before there were substantial levels ...
