A phylogenetic analysis based upon ribosomal RNA sequence characterization reveals that living systems represent one of three aboriginal lines of descent: (i) the eubacteria, comprising all typical bacteria; (ii) the archaebacteria, containing methanogenic bacteria; and (iii) the urkaryotes, now represented in the cytoplasmic component of eukaryotic cells.
基于核糖体RNA序列特征的系统发育分析表明,生命系统代表了三个原始谱系之一:(i)真细菌,包括所有典型细菌;(ii)古细菌,包含产甲烷菌;(iii)原核生物,现在存在于真核细胞的细胞质成分中。
