RNA World Hypothesis

How do you derive a human? It is a big question, but a fundamental principal of biology can assist us in finding a potential answer to how biology has advanced to far - that we exist. 

To continue to the existence of a species, passing of genetic information from parent to offspring must occur. This process is known as meiosis and requires genetic replication to take place.

Replication must take place. 

Interestingly prydamine (nucleotides incorporate prydamine  in their structure) and nucleotides adenine, guanine and thymine have been found on meteorites and supports the hypothesis of panspermia.

RNA has been shown to have the ability to self-replicate.
