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.
