How did life begin.

But that does not answer the question of how life began; it just pushes the issue from earth into space. Scientists speculate about the existence of molecules that preceded genetic material as we know it today. These molecules are supposedly more likely to arise spontaneously from inert material and are self-replicating. Deep sea vents, or "black smokers" as they are often called, occur at oceanic ridges where new sea floor emerges from the Earth's mantle. Scientists believe that some of the earliest life on Earth may have formed around these vents when chemical rich material from within the Earth poured into the oceans. Today's "vent communities" include tube ...How did those primitive cells start behaving like life: growing, dividing, and passing on advantageous traits to the next generation? The origins of life are especially murky because the geological record—the layers of rock and embedded fossils that hold clues about the history of Earth and life—disappears at roughly 3.9 billion years ago, erased by …Very few things are more exciting for an up-and-coming actor than the moment they finally make it big.
