My name is Samvak Nin and I am a Colonist in Brussels morning and today we are going to discuss my favorite topic, sex.

Or more precisely, homosexuality.

In the face of fierce opposition by the Christian Orthodox Church and other conservative forces, Greece just passed a law legalizing same-sex marriage and parenting.

The use of the word marriage may be historically inaccurate. Union would have been better.

But should homosexuals be allowed to serve as parents? What do we know about homosexuality to start with?

A growing body of scientific evidence links the etiology of homosexuality to prenatal hormonal imbalances and to the presence of endocrine disruptors.

In other words, it is a biological foundation, biological template. And still, though genetically predisposed, homosexual behaviors, mate selection and sexual scripts are probably acquired.

The outcome of environment and nurture rather than nature. The jury is still out, admittedly.

Recent studies in animal sexuality serve to dispel two common myths.

That sex is exclusively about reproduction and that homosexuality is an unnatural sexual preference.

It now appears that sex is also about recreation as it frequently occurs out of the mating season and with no reason for procreation.

In same-sex copulation and bonding, a common in hundreds of species from bonobo apes to gals. See gals.

Moreover, homosexual couples in the animal kingdom are prone to behaviors commonly and erroneously attributed only to heterosexual.

The New York Times reported in its February 7, 2004 issue about a couple of gay penguins who are desperately and recurrently seeking to incubate eggs together.

In the same article, Love the Dare Not Squeak Its Name, Bruce Bejmill, author of the groundbreaking biological exuberance animal homosexuality and natural diversity, defines homosexuality as any of these behaviors between members of the same sex, long-term bonding, sexual contact, courtship displays or the rearing of young.

Still, that a certain behavior occurs in nature, certain behavior is natural, does not render it moral. Infanticide, patricide, suicide, gender bias and substance abuse are all to be found in various animal species.

It is futile to argue for homosexuality or against it based on zoological observations. Ethics is about surpassing nature, not about emulating it.

The more perplexing question remains, what are the evolutionary and biological advantages of recreational sex and homosexuality?

Surely both entail a waste of scarce resources.

Convoluted explanations such as the ones preferred by Marlene Zuck, homosexuals contribute to the gene pool by nurturing and raising young relatives.

These explanations defy common sense, experience and the calculus of evolution.

There are no field studies that show conclusively or even indicate that homosexuals tend to raise and nurture their younger relatives more than strays do.

Moreover, the arithmetic of genetics would rule out such a stratagem.

If the aim of life is to pass on one’s genes from one generation to the next, the homosexual would have been far better off raising his own children who carry forward half his DNA rather than his nephew or niece, with whom he shares merely one quarter of his genetic material.

And often overlooked fact is that recreational sex and homosexuality have one thing in common, they do not lead to reproduction.

Homosexuality may therefore be a form of pleasurable sexual play. It may also enhance same-sex bonding and train the young to form cohesive, purposeful groups in the army and boarding school, for example.

Furthermore, homosexuality amounts to the culling of 10 to 15% of the gene pool in each generation. The genetic material of the homosexual is not propagated and is effectively excluded from the big roulette of life.

Growers of anything from cereals to cattle similarly use random culling to improve their stock.

As mathematical models show, such repeated mass removal of DNA from the common brew seems to optimize the species and increase its resilience and efficiency.

It is ironic to realize that homosexuality and other forms of non-reproductive, pleasure-seeking sex may be key evolutionary mechanisms and strategies and integral drivers of population dynamics.

Reproduction is but one goal among many equally important end results.

Heterosexuality is but one strategy among few optimal solutions.

Studying biology may yet lead to greater tolerance for the vast repertory of human sexual foibles, preferences, orientations and predilections.

Back to nature in this case, may be forward to civilization.
