Primordial Soup Might’ve Needed RNA Contribution To Spawn Life On Earth

If the asteroid-driven “primordial soup” hypothesis is not acceptable for you, there is also another theory regarding how life evolved on Earth. Accordingly, RNA might have been at the basis of life on Earth.

Similar to the DNA, RNA holds genetic information and has the capacity to bend itself into 3D patterns and trigger chemical responses. However, it hasn’t the ability to replicate itself. RNA looks like the obvious very first stage of life should’ve taken to become a more complex form of existence. However, when the RNA is bent into 3D patterns it is capable of turning into ribozyme enzyme.

Enzymes the very foundation of other chemical reactions, so, the key to all should be developing ribozyme which could launch an RNA replication when it is in it’s bent in its 3D pattern.

Life on Earth mystery of “primordial soup” might be explained by RNA

The common way to conduct RNA self-replication is to aggregate the chemical constituents (adenine, guanine) to one RNA strip, one at a time. However, a new discovery conducted by the Medical Research Council made it possible to aggregate chemical constituents three at a time.

This procedure would reveal how the RNA would’ve replicated to offer the primordial model for the life evolution on Earth. However, at present, no form of existence on Earth replicates like this.

It could mean that more evolved forms of life, including humans, have developed a totally new approach for RNA to replicate itself, or the key to RNA reproduction was lost biologically many years ago. Or, possibly, even more enticing, RNA came up with a different approach to transforming itself from a string of chemicals to a primitive form of life, and we have just encountered this new approach.

“This is a truly exciting example of blue sky research that has revealed important insights into how the very beginnings of life may have emerged from “primordial soup” some 3.7 billion years ago,” admitted Dr. Nathan Richardson, one of the researchers.
