Dry Spells Could Have Been Essential For Life to Emerge on Earth

How life emerged on Earth from an assortment of non-living molecules is a stubbornly enduring mystery but now we could have some more clues thanks to a recent study.

New Set of Chemical Reactions Could Finally Explain How Life Started on Earth

the team's overall results suggest that carbon dioxide was a vital ingredient for the emergence of life on Earth – but only when combined with other ingredients.

More Evidence Life's Building Blocks Came to Earth From Space

We still don't know just how the first life emerged on Earth. One suggestion is that the building blocks arrived here from space; now, a new study of several carbon-rich meteorites has added weight to this idea.

Potentially Alive 830-Million-Year-Old Organisms Found in Ancient Rock

An incredible discovery has just revealed a potential new source for understanding life on ancient Earth.

The First Explosion of Life on Earth Made a Deep Impact

The Cambrian Explosion - around 541 million years ago - was when life and organisms really got going on planet Earth. Now new research has revealed how that explosion of life has left behind traces deep within Earth's mantle.

Nearby Supernovae Were Essential to Life on Earth

A new research article sheds light on another way that supernovae support life. Supernova activity in Earth’s neighbourhood may have led to more oxygen in the atmosphere. And oxygen is necessary for complex life.

Rare meteorite could uncover secrets to life on Earth

The Winchcombe meteorite is an extremely rare type called a carbonaceous chondrite and is thought to date back to the beginning of the solar system. It is rich in water and organic matter.

Lightning played a vital role in life's origins on Earth

Lightning strikes were just as important as meteorites in creating the perfect conditions for life to emerge on Earth, according to new research. This shows that life could develop on Earth-like planets through the same mechanism.

We're surprisingly similar to Earth's first animals

According to a new study, 555-million-year-old oceanic creatures from the Ediacaran period share genes with today's animals, including humans.

Life on Earth might have arisen from RNA-DNA mix

A simple compound called diamidophosphate (DAP), which was plausibly present on Earth before life arose, could have chemically knitted together tiny DNA building blocks called deoxynucleosides into strands of primordial DNA.

Extreme Life Thrived in An Asteroid Pit After Dinosaur Extinction

When the asteroid struck our planet some 66 mil years ago, it created a 180-km impact crater and produced a gigantic magma chamber. A new research found that this hydrothermal system supported an entire microbial ecosystem.

Process that might have led to first organic molecules

New research identifies a process that might have been key in producing the first organic molecules on Earth about 4 billion years ago, before the origin of life. The process may also have relevance to the life elsewhere in the universe. 

An Organism That Thrives on Eating Meteorites

The discovery of Metallosphaera sedula - the bacteria that eats meteorites not only invites speculation on how terrestrial life could survive off world, it offers insight into how early biology could have received key nutrients through space rocks.

The Oldest Evidence of Life is Now Confirmed

The title of Earth’s Earliest Life has been returned to the fossils in the Pilbara region of Australia. A new study of the Pilbara fossils has identified the presence of preserved organic matter in those fossils.

Asteroid collision in space 466 mil years ago boosted life on Earth

Largest documented asteroid breakup in the asteroid belt during the past two billion years caused enormous amounts of dust to spread through the solar system. The blocking effect of this dust lead to cooler temperatures which in turn  caused diversification.
