What is the term that scientists use to describe the origin of life on earth

The scientists use the term 'evolution' to describe the origin of life on earth.

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.

Scientists use the term “evolution” to refer to the origin and development of life in our planet.

Explanation:

The process through which the biological changes occurred in the living things on earth and how these things have originated is regarded as the ‘evolution’ process. But the term is not limited to the living things only; it also refers to the massive changes that evolved in the galaxies, stars and other heavenly objects over time.

But the process of evolution is different for different objects. The theory of Hubble proved the expansion of earth. Through evolution various species were formed which changed again in this process.
