An article I wanted to touch on briefly at Science Daily.
The first point is the interesting tendency towards the argument, "Animals do it, so it's ok!"
The second is an evolutionist / creationist point.
The creationist would say, "Homosexual behavior in animals is a product of the Fall (even leading to genetic changes). It is representative of our rebellion, and refusal to honor the image of God. The animals are simply reflecting that behavior in us."
The atheist would say "Homosexual behavior has evolved over millions of years."
But what about Christian evolutionists? If homosexual behavior is genetic, and is encoded in base pairs from millions of years ago, is it reflective of Creation before the Fall?
Is it part of God's "good" order?
