21. Role of Natural Selection
Natural selection plays a pivotal role in the evolution of the Chernobyl dogs, acting as a filter for advantageous traits that enhance survival. In the exclusion zone, where environmental pressures are extreme, only those with beneficial adaptations, such as improved radiation resistance or effective social structures, thrive. This process leads to the gradual accumulation of favorable genetic traits across generations. As a result, the dogs that survive and reproduce are those best suited to the unique challenges of their environment, showcasing natural selection’s enduring influence in shaping the genetic and behavioral landscape of this isolated canine population.
