What are the probable mechanisms are at work? 3. * Why does natural selection in this situation favor the moths without sensory organs? 4. * What would happen if this situation occurred in an alternate universe in which genetic drift did not occur? 5. * Does genetic drift encourage genetic variation? Does gene flow from only one population to another encourage genetic variation? Does gene flow between two populations encourage it?
