The primordial soup that sloshed around billions of years ago, and eventually led to first life on our planet, might have been teeming with primal precursors of proteins.

Every day, enough sunlight hits the Earth to power the planet many times over -- if only we could more efficiently capture all the energy.

A paradigm-shifting hypothesis laid out by UC Santa Cruz astrobiologists David Deamer and Bruce Damer could reshape our idea about the origin of life

How Old Are Animals on Earth?

The origin of animals was one of the most important events in the history of Earth. Beautifully preserved fossil embryos suggest that our oldest ancestors might have existed a little more than half a billion years ago.

Sedimentary layers record the history of the Earth. They contain stratigraphic cycles and patterns that precisely reveal the succession of climatic and tectonic conditions that have occurred over millennia, thereby enhancing our ability to understand and predict the evolution of our planet.

More than 550 million years ago, the oceans were teeming with flat, soft-bodied creatures that fed on microbes and algae and could grow as big as bathmats. Today, researchers at the University of California, Riverside are studying their fossils to unlock the secrets of early life.

The tree of life, which depicts how life has evolved and diversified on the planet, is getting a lot more complicated.

Hunting for habitable exoplanets now may be easier: Cornell University astronomers report that hydrogen pouring from volcanic sources on planets throughout the universe could improve the chances of locating life in the cosmos.

One major mystery about life's origin is how phosphate became an essential building block of genetic and metabolic machinery in cells, given its poor accessibility on early Earth.

Did Life Start More Than Once on Earth?

Conditions suitable to support complex life may have developed in Earth's oceans -- and then faded -- more than a billion years before life truly took hold, a new University of Washington-led study has found.
