For this question, you will assume the role of two acquaintances living in different
countries at the end of the 19th century. First, write a letter from a British citizen to
an acquaintance in Japan, China, or Russia describing the industrialization of Great
Britain over the last 150 years. Then write a reply from the Japanese, Chinese, or
Russian citizen explaining how industrialization in that country has been different.
Be sure to acknowledge both positive and negative aspects of industrialization, and
support all claims with historical evidence.

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.
