Thekey differencebetween abiogenesis and spontaneous generation is thatabiogenesis is the theory that states all life started from inorganic molecules while spontaneous generation is the theory that states complex life arises spontaneously and continually from nonliving matter.
Abiogenesis and spontaneous generation are two theories that attempt to describe how life on Earth has begun and living things originate. Both of these theories explain the emergence of life from non-living materials. Abiogenesis explains the generation of primitive organisms while spontaneous generation explains the generation of complex organisms.

What is Abiogenesis?
Abiogenesis is a theory that states the life on Earth arose from nonlife more than 3.5 billion years ago. It also states that the first life formed on Earth is very simple and primitive. Since abiogenesis states that life originated from nonlife, this theory is opposite to biogenesis. This theory was considered as evolutionary theory. Stanley Miller is one of the pioneers in developing abiogenesis theory.
根据生物发生,有机分子是由力或无机源创建的。两者的合成proteins和RNAin the laboratory is proof of this fact. Abiogenesis argues that self-replicating molecules, together with other molecules, may have produced the basic structure of life, which is the cell. These self-replicating molecules were RNA molecules, and these RNA molecules were transformed into proteins or DNA due tomutations.
Oparin-Haldane理论还声称,在存在外部能源的情况下,可以由原始材料形成有机分子。因此,奥瓜素 - 荷兰理论的思想为在后来几十年中进行的大部分关于生物发生的研究奠定了基础。
什么是自发的?
自发的产生是一种过时的理论,即陈述生命可能源于非生命问题。希腊哲学家亚里斯多德首先提出了这种自发的一代理论。根据这一理论,生物不会从其他生物或父母降临。它只需要满足其环境中的某些条件才能发生创造。自发的产生解释了复杂生物的产生。一些例子是产生跳蚤的灰尘,腐烂的肉产生的mag,以及在黑暗角落产生的小鼠中留下的面包或小麦,等等。
Several scientists, including Francesco Redi, John Needham, Lazzaro Spallanzani, and Louis Pasteur, performed different experiments/research studies to disprove this theory. Francesco Redi showed that maggots arise from the eggs of flies rather than directly from rotting. Later, Louis Pasteur did experiments with flasks with twisted necks (swan-neck flasks) and proved sterilized broths in swan neck flasks remained sterile. Unless microbes are introducing from outside from air, the broths remained sterile, and there was no growth of microorganisms. Pasteur’s experiments disproved spontaneous generation theory by proving “life only comes from life”.
What are the Similarities Between Abiogenesis and Spontaneous Generation?
- Both abiogenesis and spontaneous generation state that living things originate from nonliving things.
- 这两种理论都不再使用,因此它们是过时的理论。
What is the Difference Between Abiogenesis and Spontaneous Generation?
Abiogenesis is a theory on the creation of organic molecules from inorganic sources while spontaneous generation is a theory on the creation of complex life from nonliving things. So, this is the key difference between abiogenesis and spontaneous generation. Moreover, abiogenesis theorizes that primitive life (self-replicating RNA and protein molecules, etc.) originated from nonliving matter while spontaneous generation theorizes on the generation of complex life (mice and maggots, etc.) from nonliving matter. Furthermore, abiogenesis has been neither proved nor disproved. But spontaneous generation theory was disproved.
Below is a summary of the difference between abiogenesis and spontaneous generation in tabular form.
概括– Abiogenesis vs Spontaneous Generation
生物发生和自发产生是国家生物可能由非生命物质引起的两种理论。因此,这两种理论都认为,非生物物体可以引起活生物体。生物发生主要讨论了原始生物的产生,而自发产生理论讨论了复杂生物的产生。此外,科学家既没有证明也没有证实的生物发生。但是,几位科学家已经反驳了自发的生成。因此,这总结了生物发生和自发产生之间的差异。
