Gradually, multicellular living things developed from the unicellular ones.

  • Protozoa, which are unicellular organisms, are the first life forms on Earth.
  • These single-celled creatures were the ancestors of multicellular life.
  • As multicellular organisms eventually evolved, new types of plants and animals were created.

Evolution of multicellular from unicellular:

  • Approximately 3.5 billion years after Earth's formation, or a billion years later, the first single-celled organisms were discovered on the planet.
  • It took longer for more sophisticated living forms to develop; the first multicellular animals didn't exist until roughly 600 million years ago.
  • An important turning point in Earth's biology was the emergence of multicellular life from simpler, unicellular microorganisms, which profoundly altered the ecology of the planet.
  • However, why cells could not go back to single-celled life is one of the unsolved mysteries of multicellular animals.

Hence, gradually multicellular living things developed from the unicellular ones.
