It also suggests that cell
life could have
emerged with a far greater variety of pre-
cellular forms than those conventionally considered, as the new giant virus has almost no equivalent among the three recognized domains of
cellular life, namely eukaryota (or eukaryotes), eubacteria, and archaea.
In order for
cellular life to
emerge and then evolve on earth, the fundamental building blocks of
life needed to be synthesised from appropriate starting materials — a process sometimes described as «chemical evolution».
