When and how did life originate on earth?
3.6 billion years afrom polymerasation of simple compounds.
The origin of life is expected to 3.6 billions years ago by the polymerisation simple compounds about 3.6 billion years ago in the hot water. That hot water was the source of different simple organic compounds. The smple organic compounds were formed in anaerobic atmosphere from water, methane, carbondioxide and hydrogen. The polymers ttained the ca[pacity of duplication like the organisms. Thank you
