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?
