Microspheres were spherical bodies with metabolic abilities that could successfully sustain their existence. However they did not contain any genetic material. Which means that they could not replicate or pass off their parts to their successive generations.
But they had no way to evolve since they could not pass off any genetic material to their offspring's. This is why RNA came into existence. RNA enabled an Organism to store its genetic material into nucleic acids, that could be passed on to generations to come. This is also how they could evolve into more complex organisms.
Microspheres are formed of proteins. It has been found that when an amino acid is permitted to get desiccated, then this amino acid produces proteins that in turn give rise to microspheres.
On the basis of the RNA world hypothesis, the first genetic substance was considered to be an RNA, and then later the DNA turned out to be the genetic substance of higher species during the passage of evolution. It was also believed that microspheres comprised encoded information within it, and at the time of the splitting of microspheres, this encrypted information may have got transferred to the upcoming generation.
