How did life on earth probably begin?
Every organism that exists or existed comes from a common ancestor billions of years ago. Life emerged from the following elements in chemistry: carbon, hydrogen, oxygen, and nitrogen. These elements form the building block of RNA, known as a ribonucleotide. Many scientists believe that RNA, or something similar to it, was the first molecule on Earth to self-replicate and begin the process of evolution that led to more advanced forms of life, such as humans. John Sutherland discovered a recipe for life which required sunlight. Although another possible recipe which contains no sunlight occurs in volcanic vents, thousands of feet below the surface of the Earth.
