Question

Quizplus · Accepted Answer

The transition from four-limbed land animals to aquatic animals with flippers in the lineage that led to modern whales is best explained by natural selection. This evolutionary process involves changes in traits of populations over generations, favoring adaptations that enhance survival and reproduction in specific environments. In this case, natural selection favored traits that improved aquatic living, leading to the reduction of hind limbs and the modification of front limbs into flippers for better swimming efficiency.
