Abiogenesis is highly probabilistic which is why it would result in very simple organisms. Abiogenesis occurs very infrequently. Perhaps only once in all of earth's 4. Spontaneous generation happens very frequently, in fact every new species could be a product of spontaneous generation. It occurs so frequently you just need to wait a week given the Spontaneous generation example of fly generation from rotting meat.
Abiogenesis only make very primitive organism Spontanous generation on the other hand can produce both simple and complex organism. Bacteria, worms, cows, flies, humans. Abiogenesis if it were done again There are more than the 20 types of amino acid. There are actually a few more bases than the 4 we have in our DNA. And the codon usage In spontanous generation events, you can get it to produce the same organism multiple times, right down to ability to mate with each other.
Flies were the example. The only reason abiogenesis is not disproved is because it can't be tested like evolution it is supposed to have happened in the past and won't happen again at least not in the same way abiogenesis is a theory proposed only because the origin of life is unexplainable by normal natural means.
Spontaneous generation was an earlier attempt at answering the origin of life that could more easily be proven or disproven. Sign up to join this community. The best answers are voted up and rise to the top.

The experiments of Louis Pasteur were foundational to cell theory that life came from life. Cell theory that life came from life has become known as biogenesis. Biogenesis is the theory that life only comes from life.
This is also known as univocal generation that the offspring of cells are the same as the parental cells that they came from. Spontaneous generation or abiogenesis is the exact opposite of biogenesis. Spontaneous generation says that life can come from non life. Biognesis says that it impossible for life to come from non living matter.
Where did these tiny microbes come from? Did they generate spontaneously from nonliving material, or did microbes and other living organisms only arise from other living organisms? Article Summary: Spontaneous generation is the debunked idea that life can, on a daily basis, arise from nonliving material.
Abiogenesis attempts to explain how life on Earth began. Swan-necked flask used in Pasteur's experiments to disprove spontaneous generation. Click here for animation and quiz. Virtual Microbiology. You have free access to a large collection of materials used in a college-level introductory microbiology course.
In modern science, it is understood that living things arise from other living things. This is cell theory; the knowledge that cells the basic units of life come from preexisting cells. Microsoft Explorer or Apple Safari. What Is Abiogenesis?
