Study Tests Theory that Life Originated at Deep Sea Vents

by Perikis Livas in Tracing Knowledge

One of the greatest mysteries facing humans is how life originated on Earth. Scientists have determined approximately when life began (roughly 3.8 billion years ago), but there is still intense debate about exactly how life began. One possibility has grown in popularity in the last two decades – that simple metabolic reactions emerged near ancient seafloor hot springs, enabling the leap from a non-living to a living world.
