how an observed pattern of molecular evolution (or the molecular clock) in wild populations …

… Maximum likelihood rates of nucleotide substitution were calculated and the molecular
clock tested for 50 RNA viruses using the single rate dated tip (SRDT) model of sequence …

… Since we now have a better understanding of evolutionary features of RNA viruses, we
focus our attention mainly on RNA viruses. In particular, we examine the rates of base …
