"Simon LeVay's review of what `causes' homosexuality will be widely regarded as authoritative because it is thorough and fair. He not only lays out the sometimes conflicting evidence but also takes pains to assess the science as good or sloppy and to judge the assumptions behind theories. And it is wonderful to encounter a scientist who writes beautifully."
-- Richard E. Cytowic, Washington Post

What makes people gay, lesbian, bisexual, or heterosexual? And who cares? Written by one of the leading scientists in the research of sexual orientation, Queer Science looks at how scientific discoveries about homosexuality influence society's attitude toward gays and lesbians, beginning with the theories of the German sexologist and gay-rights pioneer Magnus Hirschfeld and culminating with the latest discoveries in brain science, genetics, endocrinology, and cognitive psychology.
