Evidence of HGT

Virus turnover rate in ocean is rought 4 days. open ocean probabaly has 10 million per mililiter, 50 ml/mililiter in coastal ocean, 3 kinds of virus, Myovirus, Podovirus, Siphovirus, 1 - 3% of Synechococcus are visibily infected.
Local populations are the actively evolving units of a species locally adapted. Lots of cell surface properties present a different face to virus or grazers.
Evolutionary trajectory and path, balance between the drift and mutation. tRNA loci are usual insertion sites for HGT
