Pre-biotic evolution is a term that is sometimes used to indicate the processes that lead to the emergence of life on Earth. To be sure, these processes have nothing to do with Darwin's theory of evolution, although the principle of differential reproductive success may have played a role in abiogenesis as well as in evolution.
The stages in the origin of life from purely mineral conditions to the presence organic chemistry has large holes in it. They can postulate on how simple amino acids were formed and even water filled micro-cells with lipid membranes were created from primordial conditions BUT to get replicating RNA there is an unfathomable problem of creating replicating enzymes etc etc etc.
To bridge this gap several pre-biotic steps have been imagined. Some involve exotic minerals that can provided chemically active substrates on which more familiar bio-chemistry can occure. So, supposidly, there was a time that 'life' involved a whole set of elements and chemicals that have now been dropped from from what we consider organic chemistry.

When was The Evolution of Melanism created?
The Evolution of Melanism was created in 1973.
What is a change of a species over time called?
Evolution is a change in species over time.
What is evolution and how does it works?
Evolution is the development of something, widely used to describe how the existence of everything came to be. http://en.wikipedia.org/wiki/Evolution
What question did both Lamarck and Darwin try to answer with their theories of evolution?
What is the mechanism that causes evolution. Both knew evolution occurred and occurs but did not know how or why. Lamark's " desire to evolve " and " acquired characteristics " failed to explain evolution. Darwin's theory of evolution by natural selection was the better explanation.
Behavioral trends in primate evolution include?
There are many behavioral trends in primate evolution. These behavioral trends in primate evolution include hugging and kissing for example.
What is generally accepted as the origin of living organisms?
Prebiotic chemical evolution gave rise to progressively more complex molecules and eventually to living organisms
What are the molecules to be considered as prebiotic?
Its a type of molecules that are lead to prebiotic molecule formation
Which fiber functions as a prebiotic and alter the microbiota?
carrot fiber
Which fiber alter the microbiota function as a prebiotic?
carrot fiber
What is prebiotic chemistry?
Prebiotic chemistry is the field of study involving the spontaneous chemical reactions which may have led to the formation of biomolecules and/or life on early Earth. In general, prebiotic chemistry includes all possible abiotic reaction pathways leading from inorganic substances to organic substances to biomolecules or bio-like molecules.
Which fiber is most likely to alter the microbiota function as a prebiotic?
Carrot fiber
Why are soluble fibers identified as prebiotics?
Soluble fiber is considered a prebiotic because all prebiotics are fiber. However, not all fibers are prebiotic. Insoluble fiber helps transport solids through the digestive system, but soluble fiber helps stimulate intestinal bacteria associated with health and wellness.
Can dogs take probiotic and prebiotic with multi vitamins and minerals?
Yes, but I would strongly suggest that you only feed a probiotic, prebiotic or vitamin/mineral supplement that is approved for use in dogs. Human supplements and dietary aids can have inert ingredients that are harmless to humans but potentially dangerous for dogs or cats.
What is the difference between theory of evolution and language evolution?
Theory of evolution refers to animals and plants evolution along the time. Language evolution is another issue, not entirely related to the theory of evolution. It follows the theory of evolution on some way but it is related to culture evolution, not to the physical attributes evolution.
What are the dangers if any of eating tiger nuts?
You could start roaring unexpectedly. Besides... tiger nuts are a natural, healthy prebiotic replacement without known side effets. :)
What is a macro evolution?
Micro-evolution is not only a part of macro-evolution, it is the same mechanism as macro-evolution. Macro-evolution includes speciation, as a result of continuing micro-evolution.
What is the difference between evolution and theories of evolution?
Evolution is a process, theories of evolution are theories which explain that process
