What events led to Cuba being such a dangerous part of the cold war in the early 1960s

In October 1962, the Soviet provision of ballistic missiles to Cuba led to the most dangerous Cold War confrontation between the United States and the Soviet Union and brought the world to the brink of nuclear war

The Cuba-Missile crisis

Explanation: During the cold war of 1960 between Russia and America, it was believed that the Russians used Cuba (a communist state as Russia) as a base to build missiles. Due to Cuba's proximity it was believed that every state could be affected if missiles were to be launched from Cuba. In addition, when Fidel seized powee, he took over American businesses. With these undercurrents of events, Cuba was seen as a greater threat.

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.
