What evidence has biopsychology provided in the argument that sexuality is biological and not environmental?

     In 1957 the first psychological test occurred to determine if there was a biological explanation for homosexuality. This test was undertaken by American psychologist Karen Hooker (The Mother of the Homosexual Movement), who studied the relationship between psychological development and homosexuality and illness. By studying both heterosexuals and homosexuals, and matching their intelligence, educational levels, and ages, all subjects were then given three psychological tests, which were the Make-a-Picture-Story Test (MAPS), the Thematic Apperception Test, and the Rorschach (Boston University, 2012). With finding no major differences in the answers given by the groups of heterosexuals and homosexuals because of the similar scores, Hooker was able to concluded that sexuality is not based on environmental factors (Boston University, 2012). Boston University (2012), "in 1973, based on Hooker’s findings, the American Psychiatric Association removed homosexuality from its Diagnostic and Statistical Manual of Psychological Disorders and in 1975, released a public statement that homosexuality was not a mental disorder" (para. 3).     There have been other studies designed at determining whether homosexuality was or was not a genetic cause. Boston University (2012), "among the most notable were a series of studies Pillard and J. Michael Bailey, a professor of psychology at Northwestern University, conducted in the early 1990s that found that homosexuality is largely biologically determined, not environmentally influenced" (para. 4). In their identical twin, fraternal twin brothers, and adopted nonrelated brothers studies to determine if there was a genetics could explain homosexuality, they found that when one identical twin was gay there was a 52 percent chance that the other was also gay (Boston University, 2012). There was a 22 percent chance for fraternal twins, and only 5 percent for nonrelated adopted brothers (Boston University, 2012). ReferenceBoston University. (2012).

Boston suspect ID'd? Arrest not made in Marathon explosions

Boston suspect ID'd? Arrest not made in Marathon explosions, Questions are cropping up such as: Has a Boston suspect been ID'd? While no arrests have been made in the Boston Marathon bombings and explosions, media sources report progress has been made. Reportedly, a surveillance camera at the Boston bombings shows a person putting down a black bag near the finish line, citing a live CNBC broadcast on April 17.Reports begin circulating around 2 p.m. EDT that suggested a suspect responsible for the two blasts at the Boston Marathon would be taken into custody in short order. Reported Examiner...Moments later, other major news outlets began reporting a person was in custody and would be arraigned in a courthouse.However, the Boston Police Department and FBI report inaccuracies in reports, stating that no Boston Marathon suspect in the explosions was under arrest or near being taken into custody.Nonetheless, a critical piece of evidence could possibly break the case and identify a person or group responsible for the terror attacks.Sources confirmed a Lord & Taylor camera has footage that shows a man placing a dark backpack or bag down near the site of the explosions. However, it's important to note that many people were in place along the route and this could be a benign act with no link to the carnage.However, investigators are chasing down all leads that can help them track down a perpetrator.Again, regarding the question: Has a Boston suspect been ID'd? At this time, the response is no, but could change soon as more news continues to break.
