@AndyZ:
OMG this is hilarious! Christian "scientists" attempting to explain homosexuality does not have biological underpinnings by the merely describing the common phenomena of biologic variation. If it isn't hard coded into DNA, then "God" didn't intend it and it must be labelled sinful and must be shunned.
There are hundreds of thousands of DNA variations that create the phenotypical individualism we see throughout the human race. Not to mention the additional variation that is created as biology interacts with environment. How ridiculous to sanctimoniously proclaim superiority of one variation over another.
Variation is an integrate part of life that has allowed it to adapt and advance into many different strata of life. Macro-Evolution describes how certain variations will tend to be advantageous, but are wholly dependent on the type of environment to which they are exposed over long periods of time, as in hundreds of thousand to millions of years. Yet, in the micro-evolutionary scale, in which we live, variety IS the normal and desirable process of life. But if one makes certain suppositions about life's origin, one no doubt will be led to faulty conclusions that actually have no foundation in true science. And so it goes with our Christian "scientist" brethren.
Of course here things could get slightly more complicated Andy cause if we can say that variation is an integrate part of life we could say also that this "variation" may be predicated of things we don't denote as living. English then has a wonderful word: lively.
But, closing this semanic bracket which could lead us off topic, when we come to
a true science
a false science
a junk science
a sound science….etc.
thence the quite deep hole of the science, its methods and its problems seems to open...
