WebMar 8, 2024 · It is said that single-celled organisms are the oldest form of life with protocells possibly emerging 3.8 to 4 billion years ago. The first single celled organism is called LUCA (Last Universal Common Ancestor) which probably existed around 3.5 billion years ago. Scientists believe that this one cell gave rise to all the subsequent life on earth. WebEvery living thing can be traced back to the first cell on earth: a single-celled microorganism called a prokaryotic cell. Prokaryotic cells are thought to have originated on earth following a series of events that combined several organic compounds with the right environmental factors.
