One of the first major effects of imperialism was the transfer of the State to the rest of the world.

Explanation:

When a country colonized and controlled another one, its power is transferred to people who represent the laws and desires of the mother country. The powers and influence of the state are introduced to the colonized country, and the populations living there are always been remembered that they are under control of that specific country.

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.
