The remaining squirrels evolve into a population quite distinct from the original. In another forest, a bacterial infection kills 90% of the squirrels in the forest, and the remaining squirrels also evolve into a distinct population. The first instance is considered genetic drift, and the second is natural selection. Explain the difference.arrow_forward
