The missing puzzle could show light on how the beginning of life for flora and fauna came to exist by some cosmic accident or a one in billion chance, on dust ball-Earth eons ago. Researchers may have the link to account for all the evolution happening for millions of years.
Engines of creation from the first single-cell to the most complex-celled creatures owe their existence to an RNA molecule that started everything from a primordial soup.
RNA Molecules
The RNA molecule is the secret before life begins, able to duplicate, adopt morphic changes, and develop the structure we see in all cells today, reported the Express UK.
Researchers can now highlight what has happened in the past. How a simple organic compound becomes a plethora of creatures from apes to men, one idea is that primitive earth had developed ribonucleic acid (RNA) molecules about four billion years ago, noted Live Science.
The turning point for life on earth may be the constant changes from a single molecule to a complex flora and fauna, both living and extinct, beginning from RNA. Though accepted, the concept of the RNA molecules was never reproduced in a laboratory, which was hard to prove, but breakthroughs are happening now. Work done by the biologist Professor Ryo Mizuuchi and a team from the University of Tokyo is shedding light on an unreachable past eon ago and looking for the missing puzzle piece to the beginning of life on earth.
Proposing that from chemical systems to complex biology as the engine of evolution, it was called a long-term RNA replication experiment testing the hypothesis. This process was not the same as other empirical studies because it was premised in an RNA replication system based on Charles Darwin's theory of Evolution, mentioned Smithsonian Magazine.
The Japanese scientist used ribonucleic acid that was in continuous change resulting in structural mutations and be coming up with new characteristics along the way. Utilizing natural selection would be the dominant trait to allow the cell to survive. Like amoebas to complex animals as an example.
Evolutionary Transition
Professor Mizuuchi remarked that the study of ribonucleic acid could be where did all life stem from; a mystery. He added that one RNA species led to an ever-evolving system; a network of five RNAs having different ways to react would have been conflicting.
Evolutionary biology calls it the competitive exclusion principle says its almost impossible for five RNAs to exist simultaneously. These molecules should find a way to use resources one at a time to evolve successfully. But five of them existed simultaneously.
How can molecules do what they just did? It's a non-living chemical species able to generate evolutionary changes in defiance of the rule. Compared to a simple molecular replication system, complex organisms enable have constant changes in the cell. It is the missing puzzle piece of the beginnings of life with more to be known for reaching an answer; the study is posted on the Nature Communications journal.
