Mimivirus

The mimivirus debate is another chunky debate to get your teeth into. There are several hypotheses for where mimiviruses fit in the tree of life and including them as a fourth domain is only one suggestion. The wikipedia article is a good place to start and there's another good Discover article on the story but for something a little meatier try this PNAS paper with the title: 'Three RNA cells for ribosomal lineages and three DNA viruses to replicate their genomes: A hypothesis for the origin of cellular domain.'
