How was militarism practiced?

Militarism describes a period of time when a country builds up its military. This was a common practice in European history. This was especially true at the end of the 1800s. Because there was a race for colonies, countries began to build up their army and navy.

Militarism is one of the most important and energetic manifestations of the life of most social orders, because it exhibits in the strongest, most concentrated, exclusive manner the national, cultural, and class instinct of self-preservation, that most powerful of all instincts.

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.
