"x was 5-hydroxymethylcytosine, a stable nucleotide previously observed only in the simplest of life forms, bacterial viruses."
This is not a true statement, or it needs to be re-worded because what it implies is not true. 5-hydroxymethylcytosine was observed in the DNA of complex life forms back in the late 60's/early 70's as is evident from this article: http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=1178489 published in 1972.
I'm not saying that the observations discussed here are not new, but the knowledge of the presence of HMC in DNA is not new.
