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.

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.

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.

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.

The odds of life and intelligence emerging on other planets

According to a recent study, if planets with similar conditions and evolutionary time lines to Earth are common, then life should have little problem spontaneously emerging on other planets and the odds are 3:2

How Possible Life Is In The Universe

It's calculated that, thanks to rapid inflation, the universe may contain more than 1 googol (10^100) stars, and if this is the case then more complex, life-sustaining RNA structures are more than just probable, they're practically inevitable.

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.

A Place on Earth with Liquid Water But No Life

 We get excited when we detect water on another world, which so far hasn’t happened often. But this study shows that the presence of water, though tantalizing and worth pursuing scientifically, guarantees nothing.

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.

Scientists uncover genes that could hold key to how humans evolved

New computational analysis finds that more than two dozen human zinc finger transcription factors, previously thought to control activity of similar genes across species have in fact human-specific roles and could help explain the evolution.

Complex Life Might Require a Very Narrow Habitable Zone

A research into how life evolved on Earth has shown that water alone does not guarantee life – nor does the presence of oxygen gas. And that two other major biosignatures, carbon dioxide and carbon monoxide could be needed.

NASA Study Reproduces Origins of Life on Ocean Floor

A team of scientists has re-created some of the first steps of life in the lab, testing whether life could emerge on other ocean worlds.

Multicellular Life Began 1.5 Billion Years Earlier than Thought

The preservation of trace fossils, suggests that multicellular organisms that could move around to reach food resources may already have existed 2.1 billion years ago, more than 1.5 billion years older than previously thought.
