Would transfer between species, for example avian influenza,
or SIV to HIV count? Once established in a population, SIV
goes one way, HIV in a different one. On the short term, of
course, the changes are limited, but over time, they surely
diverge. Mainly, viruses propagate rapidly, and therefore
the change is _more_ visible, but it is still slower than the
average life time of a human being it seems.
