Francis Galton laid the foundations of behavior genetics as a branch of science. Twins have been of interest to scholars since early civilization, including the early physician Hippocrates 5th century BCE , who attributed different diseases in twins to different material circumstances,  and the stoic philosopher Posidonius 1st century BCE , who attributed such similarities to shared astrological circumstances. Galton, however, was unaware of the difference between identical and DZ twins. This paper was an early statement of the hypothesis that family effects decline with age. His study compared twin pairs age 9—10 and 13—14 to normal siblings born within a few years of one another. Thorndike incorrectly reasoned that his data supported for there being one, not two, twin types.

Plot[ edit ] Milo Hader writes a suicide note and cuts his wrists.

Maggie visits Milo in the hospital in Los Angeles, and suggests that he come to stay with her in their hometown of Nyack, New York for a while; he reluctantly agrees. This surprises Milo, as Maggie never expressed wanting children. Milo reacquaints himself with the town, and observes Rich Burrell , a middle-aged man working in a bookstore. Meanwhile, Maggie is taking scuba lessons, and having sex with the instructor, Billy Holbrook.
