Sexual Selection vs. Artificial Selection

"As man can produce and certainly has produced a great result by his methodical and unconscious means of selection, what may not Nature effect? Man can act only on external and visible characters: Nature cares nothing for appearances, except in so far as they may be useful to any being. She can act on every internal organ, on every shade of constitutional difference, on the whole machinery of life. Man selects only for his own good; Nature only for that of the being which she tends. Every selected character is fully exercised by her; and the being is placed under well-suited conditions of life." --Darwin

(maybe some more than others)

From an evolutionary standpoint it just makes sense.
