WHY are the squirrels able to evolve?

Answer 1

Squirrels are able to evolve due to natural selection, genetic variation, and environmental pressures. As they adapt to changing habitats, food sources, and predators, those with advantageous traits are more likely to survive and reproduce. Over generations, these traits become more prevalent in the population, leading to evolutionary changes. Additionally, their relatively short lifespans and high reproductive rates accelerate the process of evolution.
