- Scott Bidstrup "Gay Marriage: the Arguments and the Motives" 2004 - "Among the approximately 1500 animal species whose behavior has been extensively studied, homosexual behavior in animals has been described in at least 450 of those species. It runs the gamut, too, ranging from occasional displays of affection to life-long pair bonding including sex and even adopting and raising orphans, going so far as the rejection by force of potential heterosexual partners, even when in heat. The reality is that it is so common that it begs an explanation, and sociobiologists have proposed a wide variety of explanations to account for it. The fact that it is so common also means that it clearly has evolutionary significance, which applies as much to humans as it does to other animal species."
