The shells of crabs found around a particular coastal location in Japan seem mostly to resemble the legendary face of a Samurai. Given below are two explanations of this observed fact. Which of these strikes you as ascientific explanation?(a) A tragic sea accident several centuries ago drowned a young Samurai.As a tribute to his bravery, nature through its inscrutable ways immortalisedhis face by imprinting it on the crab shells in that area.(b) After the sea tragedy, fishermen in that area, in a gesture of honour totheir dead hero, let free any crab shell caught by them which accidentallyhad a shape resembling the face of a Samurai. Consequently, the particularshape of the crab shell survived longer and therefore in course of timethe shape was genetically propagated. This is an example of evolution byartificial selection.
