Ancient Earth might have had an extraterrestrial supply of vitamin B3 delivered by carbon-rich meteorites, according to a new analysis by NASA-funded researchers. The result supports a theory that the origin of life may have been assisted by a supply of key molecules created in space and brought to Earth by comet and meteor impacts.

Life took root more than four billion years ago on our nascent Earth, a wetter and harsher place than now, bathed in sizzling ultraviolet rays. What started out as simple cells ultimately transformed into slime molds, frogs, elephants, humans and the rest of our planet's living kingdoms. How did it all begin?

A new study from Western University explores the possibility that Earth's earliest life forms may have been cultivated by a meteorite impact event.

Astrobiologists have provided new information about how comets and asteroids could have delivered prebiotic chemical compounds to the early Earth.

Organisms have increased in complexity through a series of major evolutionary transitions, in which formerly autonomous entities become parts of a novel higher-level entity.

A new study published recently in PNAS explores the relationship between the origin of animals and the oxygen content of the atmosphere.

How life arose from the toxic and inhospitable environment of our planet billions of years ago remains a deep mystery.

Simply making nanoparticles spin coaxes them to arrange themselves into what University of Michigan researchers call 'living rotating crystals' that could serve as a nanopump. They may also, incidentally, shed light on the origin of life itself.

With the help of a tiny fragment of zircon extracted from a remote rock outcrop in Australia, the picture of how our planet became habitable to life about 4.4 billion years ago is coming into sharper focus.

Astrobiologists supported by the NASA Astrobiology Institute have shown that mineral species on the early Earth may have been different than the ones found on our planet today.
