Woese(1987, Microb. Rev. 51 pp 221-271) pointed out that
the 16S ribosomal RNAs of hyperthermophilic Archaea have evolved
Does anybody know other references to this fact, and to possible
I tend to think that their slow evolution has to do with extra
thermodynamic constraints on their secondary structure, but
I am probably not the first one to suggest that.
many thanks, Martijn
