Natural selection is sometimes described as "survival of the fittest." Four friends were arguing about what the phrase "survival of the fittest" means. This is what they said: Diya: "I think ‘fit' means bigger and stronger." Ayush: "I think ‘fit' means more likely to reproduce." Daniel: "I think ‘fit' means being able to run faster." Hari: "I think ‘fit' means more intelligent."
