Mutants are organisms that have undergone a change in their DNA, leading to new traits or characteristics. These changes can occur naturally through processes like mutation or can be induced by environmental factors, such as radiation or chemicals. Mutants can be found in various forms of life, including plants, animals, and even bacteria. In popular culture, mutants are often depicted as individuals with extraordinary abilities, such as those seen in comic books and movies like X-Men. While these portrayals are fictional, they draw inspiration from real-life genetic variations that can result in unique physical or behavioral traits in living organisms.
