Given that humans’ sexual choices determine who reproduces most and, in turn, which physical and psychological features are favored over time, a trait that may not help a person to survive can still provide a reproductive advantage that is passed along to offspring. In other words, in choosing a mate, one shapes the course of evolution.
由于人类性选择决定了谁能有最多的后代，从而反过来决定了那些生理和心理特征更能传递下去，因此无助于个人生存的特征仍可能提供生殖优势，从而传递给后代。换句话说，在选择伴侣的过程中，我们决定了进化的进程。
