I thought the biological imperative being the driving force for sexual attraction was common knowledge.
"The rationale behind symmetry preference in both humans and animals is that symmetric individuals have a higher mate-value; scientists believe that this symmetry is equated with a strong immune system. Thus, beauty is indicative of more robust genes, improving the likelihood that an individual's offspring will survive. This evolutionary theory is supported by research showing that standards of attractiveness are similar across cultures."

" "A preference for youth, however, is merely the most obviously of men's preferences linked to a woman's reproductive capacity"(2). The younger the female the better the capacity for reproduction, hence attributes that males find attractive and contingent on signs of youthfulness. "Our ancestors had access to two types of observable evidence of a woman's health and youth: features of physical appearance, such as full lips, clear skin, smooth skin, clear eyes, lustrous hair, and good muscle tone, and features of behavior, such as a bouncy, youthful gait, and animated facial expressions"(2) . Cross-cultural studies have found that men, despite coming from different countries find similar traits attractive in females. Men's preferences are biologically and evolutionarily hardwired to find signs of youth and health attractive in women in order to determine which females are best suited to carry on their gene, and legacy. Healthier and more youthful women are more likely to reproduce, and be able to take care of the children after birth, hence ensuring a perpetuation of the male's gene."
