U.S. scientists argue that chance alone cannot consistently produce the highly complex molecules found in all living creatures. To produce billions of copies of intricate objects like proteins, human hands, or iPhones, the universe needs a 'memory'.
An international team has analyzed samples taken from the asteroid Ryugu in 2018 by the Hayabusa2 mission and found uracil, one of the five key bases of the RNA and DNA molecules that are crucial to life as we know it.
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.
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.
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.
An incredible discovery has just revealed a potential new source for understanding life on ancient Earth.
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.
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.
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 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.
According to a new study, 555-million-year-old oceanic creatures from the Ediacaran period share genes with today's animals, including humans.
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.
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.
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.
