There is nothing in the article but a variety of competing theories. No evidence at all. In fact, the focus of the article is that genetic molecules did not form by random processes on earth, but were seeded here from somewhere else...a concept which conveniently displaces the mystery to some extraterrestrial place. This not science, it is really just a new form of creation myth.
I'm sorry that I didn't explain better. The article I asked you to read was to put the article I posted in perspective. ID/Creationist say that a cell is "irreducibly complex" and couldn't have evolved from less complex forms. Sir Francis Crick, who discovered DNA, predicted that if evolution was correct that RNA working as an enzyme could self replicate. This was one year before RNA enzymes were actually discovered. Since then there has been an hypothesis that before cells, there was an RNA world. The problem was that no one had found the right Ribozyme. That is what the article is about. They have found it! We have moved the evolution debate one major step forward to solving the life from non-life riddle.
