Question

When did multicellular life begin to appear on earth?

Answer 1

3.5 billions years ago roughly a billion years after earth firmed

Answer 2

Answer:

Large, multicellular life forms may have appeared on Earth one billion years earlier than was previously thought. Macroscopic multicellular life had been dated to around 600 million years ago, but new fossils suggest that centimetres-long multicellular organisms existed as early as 1.56 billion years ago.
