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 ...

Most scientists agree that complex life likely formed during the Ediacaran Period some 600 million years ago—right on the cusp of the well-known Cambrian Explosion. However, a new study suggests that ...

For the first time, researchers have found viruses infecting a group of microbes that may include the ancestors of all complex life. The discovery offers tantalizing clues about the origins of complex ...

Scientists are one step closer to understanding the origins of complex life on Earth after shedding new light on a mystery about our microbial ancestors. The key, they suspect, may lie in how simple ...

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 ...

According to a new study, eukaryotes -- complex life forms with nuclei in their cells, including all the world's plants, animals, insects and fungi -- trace their roots to a common Asgard archaean ...

Researchers now have a better idea of what our early ancestors looked like, where they lived, and how they functioned. From the highest mountains to the deepest ocean, the driest desert to the lushest ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Detailed view of an active lava flow, hot magma emerges from a crack in the earth, the glowing lava appears in strong yellows and ...

The evolution of complex life is strictly dependent on mitochondria, the tiny power stations found in all complex cells, according to a new study by Dr Nick Lane, from UCL (University College London), ...
