Scientists have recently discovered a universal common ancestor, a single-celled organism that is believed to be the origin of all life on Earth. This new discovery has the potential to revolutionize our understanding of the history of life on our planet.

The universal common ancestor is believed to have lived between 3.5 and 3.8 billion years ago in a shallow marine environment. It is thought to be the common ancestor of all living organisms, from bacteria to humans. This discovery provides an important new insight into how life evolved on Earth, and could help us to better understand the evolution of other life forms on other planets.
