Detailed explanation-1: -abiogenesis, the idea that life arose from nonlife more than 3.5 billion years ago on Earth. Abiogenesis proposes that the first life-forms generated were very simple and through a gradual process became increasingly complex.

Detailed explanation-2: -One of the leading theories is that life emerged from chemical processes in Earth’s early ocean. Simple chemical precursors, such as water, carbon, and hydrogen, mixed and mingled until they formed complex polymers like DNA, RNA, and protein-the building blocks of life.

Detailed explanation-3: -A natural process that leads to the evolution of life forms from non-living matter is known as abiogenesis. The theory of abiogenesis was proposed by Thomas Henry Huxley. The theory of abiogenesis states that the evolution of living forms from non-living matter is spontaneous.

Detailed explanation-4: -So, the correct answer is ‘Origin of life from non-living substances’.

Detailed explanation-5: -Biogenesis is the theory that living things can only come from other living things. It was developed in 1858 by Rudolf Virchow as a counter-hypothesis to spontaneous generation. Before Virchow, it was widely accepted that microorganisms simply appeared as a result of spontaneous generation.
