DNA or RNA?

I have to admit that reading about DNA and RNA this morning on the way to work, took me back to those biology classes I took in high school. So imagine my amazement when I came upon this article over at NewScientist entitled “Earth’s First Life May Have Sprung Up in Ice” by Linda Geddes.

It talks about how it maybe RNA and not DNA that brought about the first life here on earth. At the same time I was just starting to read chapter 17, What is Life?, in The Mathematics of Life with Ian Stewart also talking about the role of RNA and it’s relationship to DNA.

Wow!
