Alarge population of mice (2000 individuals) lives in an area dominated by small shrubs in the desert. when the population size got too high, a small group of 6 individuals left and colonized an area adjacent to the original population's home, but this area is primarily dominated by trees instead of shrubs. there is no gene flow between the dispersers and the original population. a researcher sequenced the genomes of representative individuals from both populations and found substantial genetic differences between them. which of the following would most account for the amount of genetic differences observed?
divergence between the two populations was caused solely by drift.
since the original dispersal event, the small population will have evolved more than the large population.
divergence between the two groups is high because of gene flow between them.
the divergence between populations could only have been caused by stabilizing selection.
