Herbert W. Conn: Formative decades of microbiology
... How, then, does one bacterial species become two? A theory of bacterial speciation can draw on the fındings of zoologists and botanists, as Conn would probably suggest today, but we need to take into account the ways in which recombination and population size differ when going from bacteria to multi ...
