The archaeal solutions with the revolution taken care of recombination machinery which was in essence bacterial, whereas the eukaryotic products broke using this type of bacterial continuity. They launched cell fusion and ploidy cycles into mobile existence histories. Cavalier-Smith argues that both bouts of mechanical evolution were being determined by comparable selective forces: the necessity for correct DNA replication without loss of viability.[84]
