Every great country pretended to have a colonial empire, as the English conceive it. The empires of the Modern Age not only exploited the territory, but sought to establish themselves in it definitively, they became part of the crown. But the empires of the industrial revolution intend only to exploit the territory. It is about removing raw materials from the undeveloped regions and exporting the processed products to these same regions, with a much higher added value. Of course, it is not taken into account that in these regions there are no capitals with which to buy them. The undeveloped regions become underdeveloped.

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.
