The organism from which all modern life is descended is called the last universal common ancestor - and scientists are still trying to figure out what it was like.

Perhaps life is more common in the universe that we think.
Life seems to just mysteriously ‘emerge’ from non-living parts, such as elementary particles.
Evolutionary geneticist Jenny Graves loves classical choral music, but grew tired of its biblical themes. So she set out to write an alternative based in science.
The discovery of a key component of RNA in samples from asteroid Ryugu adds weight to the theory that basic organic molecules may have arrived on Earth from outer space.
Astronomers have long known where water is first formed in the universe and how it ends up on planets, asteroids and comets. A recent discovery has finally answered what happens in between.
Some physicists think we live in a multiverse, surrounded by universes not quite like our own. What does that mean for life?
In the deep, dark ocean, sunlight-deprived bacteria turn to different sources of energy: dissolved hydrogen and carbon monoxide.
Ancient rocks from Western Australia may not contain the world’s oldest fossils – but they do preserve organic compounds that may have formed the raw materials for the first living cells.
Within hours of its landing, samples of the Winchcombe meteorite had been recovered and its origins tracked back beyond Mars to the asteroid belt.
A study has found that microorganisms living on Mars billions of years ago may have left the planet uninhabitable.
The chemical reaction that forms essential biomolecules like proteins and DNA normally doesn’t occur in the presence of water. Microdroplets provide a unique environment that make it possible.
We may be on the brink of discovering whether water and organic material, which enabled life on Earth, came from asteroids.
Volcanic eruptions on the seafloor are mysterious, but new research provides fresh clues.
It looks like a broken barbeque brickette, but the newfound meteorite is a capsule of the Solar System’s history that could reveal the secrets of the origin of life.
If the building blocks of life were present at the time that Earth was born, this could mean life is common in the universe.
Unlike our hellish neighbour Venus, Earth was far enough from the Sun for liquid water to form and create a more hospitable environment for life.
How ancient microbes survived in a world without oxygen has been a mystery. Scientists discovered a living microbial mat that uses arsenic instead of oxygen for photosynthesis and respiration.
We don’t fully understand viruses, and we’re still trying to understand life.
Scientists have for the first time created shown how the precursor to living cells could have formed around deep-sea hydrothermal vents.
