Humankind has always been looking for an answer to the question of how life began and coming up with different theories on the origin of life. But now for almost two centuries, Darwin's theory of evolution has been shedding light upon many enigmas that were unknown to humans.

Inspired by the theory of evolution, researchers at the University of Tokyo conducted a long-term experiment on RNA replication and through this, they discovered a transition from a chemical system to biological complexity. Eventually, the research team created an RNA molecule that can not only reproduce but also "evolve" into a variety of more complicated molecules, according, to a study published in Nature Communications. This finding can give us clues about the early stages of evolution.

The new finding is a significant breakthrough in terms of Darwinism because the researchers experimented with a unique RNA replication system, which leads to a self-perpetuating process of continuous change based on mutations and natural selection.
