In biology, abiogenesis, or informally the origin of life, is the natural process by which life has arisen from non-living matter, such as simple organic compounds.

What is an example of abiogenesis?

For example, every time meat is left to rot, it generates flies. Spontaneous generation gives rise to complex organisms such as flies, animals and even humans. Higher organisms are the result of spontaneous generation, and they don't evolve from other life forms.

What is the concept of abiogenesis?

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.
