Answer:
The scientists use the term 'evolution' to describe the origin of life on earth.
Step-by-step explanation:
Up till today, scientists have proposed various theories for the evolution of life on Earth. Each theory has their drawbacks so there is no such theory which can exactly explain the formation of life. The question of the origin of life still remains unanswered in science.
Most commonly, scientists believe that all life today evolved from a single primitive species. The theory of abiogenesis i.e living things form from non-living things has been proved to be wrong.
