Abstract
The origin of life is a long-standing mystery puzzling many people. This mystery possesses not only philosophical but also important biological significance. To unveil this mystery, the searches for the root of life, or the last universal common ancestor (LUCA), based on comparative-genomic analysis have been intensively performed on rRNAs, tRNAs and proteins sequences. The current search pointed to a Methanopyrus-proximal LUCA, which opens up the reconstruction of Lucan biology and helps to delineate the evolutionary pathways.
