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 new study suggests that life's ingredients may have come from microscopic particles of cosmic dust filled with life's elemental building blocks.
- Over 500 naturally occurring compounds known as amino acids exist.
- Life may have arrived on Earth through cosmic dust, rather than big space rocks.
Life spontaneously stemmed from the planet’s primordial soup of amino acids and organic molecules.
A study published in the Monthly Notices of the Royal Astronomical Society supports the cosmic dust theory.
Author's summary: Life may have originated from cosmic dust particles.
