How is the mood of "to build a fire" reflected in the plot?

Mood is a key feature in literature since it allows the reader to feel identified  with the characters and the story. "To Build a Fire" by Jack London is the story of a man who despite of the bad weather conditions decides to make a journey. The mood and atmosphere is conveyed in this play by means of repetitive imagery. Hence, London uses a mood of loneliness in this story and it is reflected in the individualist attitude of the main character who decides to ignore the warnings given by others.

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.
