Every organism carries genes, which serve as unique blueprints determining traits like eye color, nose shape, and hair texture. When organisms reproduce, they transfer these blueprints to their young, resulting in variations that are never identical. This process ensures that each individual is distinct. Researchers gain insights into evolution through fossils, which reveal the appearances of ancient life forms. By studying these fossils, scientists can trace the changes that have occurred over vast periods, spanning thousands to millions of years, illuminating the journey of life on Earth.
