Describe the four stages of the hypothesis for the origin of life on earth by chemical evolution

Biology

VashaNatasha [74]3 years ago
4 0
It would be nice to see the 4 stages titled to have a clue to what they could be. You see, chemical evolution is a myth, like Darwin's "warm little ponds." There are no naturalistic processes that have any power to accomplish the complex, diverse, extensive and highly non-entropic assembly of biochemical elements, molecules and assemblies into even the simplest life.

There is no primordial soup, panspermia is a distraction, none of the intractable issues for the origin of life.

Logically, the first step is collection of all elements, second, first level assembly of amino acids lipid membranes, proteins, third, higher level combination of biochemical molecules and generation of nucleotide coded DNA containing the processing code for generation and production of RNA, enzymes ribozymes and all other cellular functions, then fourth, the execution of all metabolism, nutrient collection, waste elimination and reproduction consistent with a living organism. Admittedly speculative since chemical evolution is a myth.

pickupchik [31]
Salinity refers to an increase in the dissolved salt content of a body of water. Salinity has great impacts on the type of organisms that live inside the water. In the question given above, the salinity occurs as a result of non natural influence; since most of the organisms living inside the water before probably have specific optimal salinity range, if the salinity exceed the range they can cope with, they will probably migrate away from the water, those that refuse to migrate will probably die out and new species which can cope with the salinity level will emerge.
