Evolution cannot execute a grand redesign of a body part because it operates through gradual changes over generations rather than sudden, large-scale alterations. Natural selection favors small, incremental adaptations that improve an organism's fitness in its environment. Additionally, existing structures and genetic constraints limit the extent of modifications, as radical changes could disrupt essential functions. Thus, evolution tends to refine and optimize rather than completely overhaul biological systems.
