Question

SUGGEST WHY ANIMAL LIKE ORGANISMS DIS NOT APPEAR ON EARTH UNTIL AFTER THE FIRST ORGANISMS THST COULD PHOTOSYNTHESIS HAD APPEARD

Answer 1

Answer:

The earliest oxygen-producing microbes may not have been cyanobacteria. Ancient microbes may have been producing oxygen through photosynthesis a billion years earlier than we thought, which means oxygen was available for living organisms very close to the origin of life on earth. Researchers studied the molecular machines responsible for photosynthesis and found the process may have evolved as long as 3.6 billion years ago.
