Part I: What are the evolutionary origins of contemporary patterns of sexual and romantic relationships? Where does evolution leave off and where do history and culture begin? -- Part II: How do early family and peer relationships give rise to the quality of romantic relationships in adolescence and young adulthood? -- Part III: How do early romantic and sexual relationships influence people contemporaneously and later in life? -- Part IV: To what extent are current trends in sexual and romantic relationships problematic for individuals, families, and society? What are effective intervention approaches at the level of practice |

The human eye is a remarkable optical device. In less than a second, a young human eye can accommodate from infinity to closer than 10 cm. Accommodation occurs with minimal effort and can be rapidly repeated with no apparent evidence of fatigue. Unfortunately, maximum accommodation decreases throughout life and by the fifth decade leads to presbyopia, the inability to read at a normal working distance. Interestingly, the mechanism by which the human eye is able to adjust focus has been debated for over 300 years. No previous theory has been put forth that can account for all the physical chang |
