Explanation:

As the early Americans adhered to the Manifest Destiny and expanded to the Western part of the Continent, they engaged in different activities from their Northwestern counterparts.

The territories that the Americans took over to the west had fertile land for agriculture as well as rich mineral deposits which led to minning. This often put them at loggerheads with the Native Americans and differentiated them from the North Eastern states which were more industrialized.

explanation:

genetics is the study of how dna works, the methodologies defining the new recent technologies allow scientist to have a panoramic view of the entire dna landscape, especially how genomes interact with their environment, including off course, factors outside their organisms.

thus is very possible the existence of both scenarios, where populations of isolated individuals have different genetic traits, and share traits related to genetic mutation, due rats can easily travel overseas using human transport channels. so scientists could get a vast number of data, including human interaction, evolution of rodents, health development, spread of infections, development of new organisms, how genomes evolve in different environments and so on.
