By reconstructing ancient nitrogen-processing enzymes, scientists are uncovering new clues about how early life survived on a ...

Oxygen played a key role in the evolution of complex organisms, according to new research published in BMC Evolutionary Biology. The study shows that the complexity of life forms increased earlier ...

Life on Earth began in a way that still boggles the mind. Around 4.5 billion years ago, a chemical process called abiogenesis occurred, where life emerged from non-life. Imagine a hot, watery mix of ...

Chris Impey receives funding from the National Science Foundation and the Howard Hughes Medical Institute. We have only one example of biology forming in the universe – life on Earth. But what if life ...

A study presents a striking example of cooperative organization among cells as a potential force in the evolution of multicellular life. The study is based on the fluid dynamics of cooperative feeding ...

The Triassic is one of the most important periods in the evolution of life on Earth. After one of the greatest mass extinctions 252 million years ago, not only the dinosaurs but also many other groups ...

Fossilized skeletons and shells clearly show how evolution and extinction unfolded over the past half a billion years, but a new analysis extends the chart of life to nearly 2 billion years ago. The ...

This artist’s impression shows the planet-forming disc around the star V883 Orionis. In the outermost part of the disc, volatile gases are frozen out as ice, which contains complex organic molecules.

RIVERSIDE, Calif. – A deficiency of oxygen and the heavy metal molybdenum in the ancient deep ocean may have delayed the evolution of animal life on Earth by nearly two billion years, a study led by ...
