LONDON (Reuters) – Earth’s first life evolved after a small planet, theia collided with the Earth. According to British Scientist, The side effect of the collision was the appearance of the first life on Earth. Scientists discovered that this happened 100 million years earlier than previously thought. British scientists confirm the start of life on Earth 4 billion years ago.
The researchers worked again by studying the evolutionary history of current animals to find some new details that reveal the first life on earth and about the “common ancestor” that scientists describe as a single-celled organism. The researchers found that this organism is the ancestor of every living organism on Earth, It existed about 3.9 billion years ago when the earth was still in its early stages.
Science has enabled us to travel in space and trace the history of the whole universe, but we can not yet answer exactly how and when life came to our planet, explains Holly Bates, a doctoral candidate in paleontology at Bristol University.
Scientists have used the fossil record to try to answer these questions. However, as paleontologists realize fossils are difficult to find as we move back, and we do not have much of the rocks available for study, due to the earth’s rock reclamation system, Through multiple operations.
Offcourse every hypothesis presented regarding the first life on earth on the scientific pattern cannot possibly be confirmed that their discovery is legitimately accurate due to the absence of concrete proof. British scientists confirm the start of life on Earth 4 billion years ago is also a hypothesis which can be taken as well researched theory.
