Question

Quizplus · Accepted Answer

Natural selection is about the differential reproductive success of individuals based on their inherited characteristics. Those individuals whose traits best enable them to survive and reproduce in their environment will pass on those advantageous traits to their offspring, leading to evolution over time. Inheritance of acquired characteristics (choice B) was a discredited idea proposed by Lamarck. Change in response to need (choice C) is not a sufficient explanation for natural selection, as adaptations are not always purposeful or conscious efforts to meet a specific need. The idea of constant improvement leading to perfection (choice D) is not supported by evolutionary theory, as there is no overarching goal or direction to evolution.
