What aspects of recent history made the french and germans accept this idea

Napoleon's speech had a strong appeal to the people because it offered them an opportunity to find steadiness and prosperity in their country again, through him. Bismark and Napoleon both offered themselves as leaders who will take care of their country and their people. Their speeches differ because Bismark is promising to help protect what they already have, where as Napoleon is promising to gain back what his people need. I believe that their similarities are more important, due to the fact that both of them are strong leaders offering their country something that is needed. These selections teach us that Realpolitik is based on practicality and realistic ideas, not based on morality or ethics.

hope it helps!

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.
