✓ Correct answer: a) use and disuse of organs
ExplanationThe mechanisms of organic evolution refer to the processes by which populations of organisms change over time, leading to the diversity of life forms seen today.These mechanisms explain how species evolve, adapt, and sometimes go extinct.The loss of limbs in snakes is explained by Lamarck’s Theory of Use and Disuse, which suggests that organs that are frequently used develop and strengthen while those that are not used weaken and eventually disappear over generations.Snakes evolved from lizard-like ancestors that originally had limbs.As they adapted to a burrowing or slithering lifestyle, they stopped using their limbs for movement.According to Lamarck’s theory, since the limbs were not used, they gradually reduced in size and eventually disappeared over many generations.455
