Neat stuff btw, I wonder when that RNA bands starts replicating itself. I guess there's still some road from RNA to life.
It's now thought that life did not begin with DNA, but RNA, specifically because RNA can act as both a coding molecule and an enzyme. Specialization into a molecule solely for coding, DNA, and enzymes crafted from amino acids, proteins, came later as the genetic process itself evolved. At the very least, we know that the coding sequences themselves didn't always match like they do today.
It's also important to note that even basic bacteria took two to three billion years of evolution. Multicellular organisms were able to rapidly develop and diversify because much of the basic templates were already hammered out. Once you have an organism with prokaryotic cells, a brain, two eyes, a circulatory system, a respiratory system, a skeletal system with four limbs and a spine, and sexual reproduction, you pretty much have every vertebrate animal ready to go outside of proportion tweaking and miscellaneous traits.
