Two populations of mice live in adjacent forest patches connected by a narrow corridor of suitable habitat. Gene flow between the populations is limited but not zero - approximately 2-3 individuals migrate between patches each generation. Over time, researchers notice that the populations are developing different coat color patterns: one population is evolving darker fur while the other maintains lighter fur. Despite this divergence, occasional hybrids are observed and these hybrids are healthy and fertile. After 500 generations of limited gene flow, what is the most likely evolutionary outcome for these populations?
