Diverging slightly from the subject, but still dealing with evolution.  
I am informed that Varroa destructor (unlike Varroa jacobsonii for 
which it was at first mistaken) has never been found on Asian honeybees 
 from whence it was presumed to have transferred. Is that because we 
haven't looked hard enough; that it has somehow become extinct where 
first it developed; or that by a rapid evolutionary leap it transformed 
its shape and (presumably somebody has compared) genome when it changed 
hosts?
