Origin of Life on Earth
The scientific community is divided on the origins of life on Earth, with two main theories: life stemmed from the planet's primordial soup or arrived on interstellar debris.
However, a study published in the Monthly Notices of the Royal Astronomical Society suggests that life's ingredients may have come from microscopic particles of cosmic dust.
- Amino acids, the building blocks of life, may not have arrived on big space rocks.
- There are over 500 naturally occurring compounds known as amino acids.
Life spontaneously stemmed from the planet’s primordial soup of amino acids and organic molecules.
Author's summary: Cosmic dust may have brought life's ingredients to Earth.
