There's absolutely no evidence of any kind to demonstrate that Prokaryotes, Eukaryotes, & Viruses have common origin.

There's a lot of speculation on the matter, but no evidence ~

Just to name one of a hundred examples, the ribosomal proteins of prokaryotes and eukaryotes are highly homologous. There is also substantial genomic evidence eukaryotic organelles (mitochondria, chloroplasts) were originally prokaryotic symbiotes.
