Of all the scientific mysteries, this is probably the greatest one of all ”“ how did life on Earth begin? We are not talking about how it evolved into the diversity of lifeforms we see today. We are talking about how it originated in the first place.
For all his immense insight into evolution, Charles Darwin himself was stumped. He suggested that whatever the mechanism was that had led to the first replicating lifeforms, it most probably arose in some “warm little pond”, a primordial soup of pre-biotic ingredients where the seed of life first germinated on the early Earth.
Now scientists have developed an experiment demonstrating how the very first self-replicating molecules may have formed about 4 billion years ago when the Earth was like any other lifeless planet that had yet to experience the radical transformation of living, breathing creatures.
