A virus HA antigenic evolution appears to be characterized more by punctuated, sporadic jumps as opposed to a constant rate of antigenic change. Using...

between organisms of different species, either through hybridisation, antigenic shift, or reassortment, is sometimes an important source of genetic variation...
