Abstract
It is generally accepted that primitive cells were endowed with relatively small genetic systems with reduced encoding capacities. How the transition from such small genomes to the more complex ones observed in extant prokaryotes took place is still unknown, but it may have involved duplication of genes and of larger segments, horizontal transfer, cell fusion events, and perhaps even whole genome duplications (Casjens, 1998).
