Question

What is the theory of biogenesis? How is it different from the theory of abiogenesis?

Answer 1

Hint: The theory of Biogenesis and Abiogenesis is the counter theories to the theory of spontaneous generation that describe the origin of life from mysterious vital force.

Complete answer:
Biogenesis is the production of new living organisms or organelles from other living things. It was termed by Henry Charlton Bastian. It was developed in 1858 by Rudolf Virchow as a counter hypothesis to spontaneous generation theory.
Before Virchow, it was widely accepted that microorganisms simply appeared as a result of spontaneous generation.
Conceptually, biogenesis is primarily attributed to Louis Pasteur and encompases the belief that complex living things come only from other living things, by means of reproduction. That is, life does not spontaneously arise from non-living material, which was termed the spontaneous generation theory.
The generation of life from non-living material is called abiogenesis. Thomas Henry Huxley used the term Abiogenesis. It occurs through stepwise chemical and molecular evolution over millions of years. The transition from non-living to living entities was not a single event but an evolutionary process of increasing complexity that involved molecular self-replication, self-assembly, auto-catalysis, and the emergence of cell membranes.
The classic Miller-Urey experiment demonstrates that life-forming components arise from the inorganic components.

Note:
The theory of biogenesis and abiogenesis describes all the possibilities of how life could have originated. Biogenesis describes the origin of life from the existing living factor. The theory of abiogenesis suggests the origin of life from the non-living things in the early atmosphere billions of years ago.
