The answer to this question is "to put the two groups into the different environment" as a scientist separates a population of fruit flies into two groups and this would increase the rate of speciation in this population. This is the best solution that the scientist could do to increase the rate and get a more reliable result and observations.
        
                    
             
        
        
        
<u>Answer:</u>
<em>If no other changes occurred emigration would have a negative impact on the population density of a group of organisms.
</em>
<u>Explanation:</u>
<em>Emigration is the movement of a part of population out of an area into a new area. </em>It has a negative impact on the population of the old area and positive impact on the population of the new area. 
Population density is the population per unit area that is population per square kilometer.
Thus population density will also be negatively affected by emigration. <em>Hence an area that previously was densely populated might become a sparsely populated area due to emigration.  </em>
