Gay marriage would undermine marriage because it is a legal and moral institution designed to promote and protect procreation and raising of children. Gay marriage would desecrate God's mandate that heterosexual couples have to mate and procreate. Is any of this true, and if so, does it matter? There are two ways this can be refuted: by showing what its logical conclusions would be if actively employed, and by taking apart its philosophical basis.
Scientists quash idea of single 'gay gene'

Nsikan Akpan Nsikan Akpan. In its stead, the report finds that human DNA cannot predict who is gay or heterosexual. Sexuality cannot be pinned down by biology, psychology or life experiences, this study and others show, because human sexual attraction is decided by all these factors. The study shows that genes play a small and limited role in determining sexuality.
Why Gay Is Not the New Black
By Michael Le Page. There are numerous evolutionary mechanisms that might explain homosexual behaviour, which is common in many species of animals. Homosexual behaviour has been observed in hundreds of species , from bison to penguins.
Writing in the journal Science , an international team of researchers report how they drew on existing genetic databases to conduct the largest study yet into genetics and same-sex sexual behaviour. The team stress that they did not focus on identity or orientation, and did not include transgender individuals. By looking at sexual behaviour and relatedness of individuals, they estimated that about a third of the variation in same-sex behaviour is explained by genetics. Dr Brendan Zietsch, co-author of the research from the University of Queensland in Australia, said that does not mean the rest is due to upbringing or culture.
