The first, according to a report in the press on 20th October of this year, took place in a lake in Scotland 385 million years ago. It was then, according to this new discovery, that two fish came together to perform the first instance of sexual reproduction known to science. Until then all life had propagated itself asexually, by cell division, budding, fragmentation or parthenogenesis, all of which are far simpler and more economical than the division of life into male and female, each with a different role in creating and sustaining life.
When we consider, even in the animal kingdom, how much effort and energy the coming together of male and female takes, in terms of displays, courtship rituals, rivalries and violence, it is astonishing that sexual reproduction ever happened at all. Biologists are still not quite sure why it did. Some say to offer protection against parasites, or immunities against disease. Others say it’s simply that the meeting of opposites generates diversity. But one way or another, the fish in Scotland discovered something new and beautiful that’s been copied ever since by virtually all advanced forms of life. Life begins when male and female meet and embrace.
You can go to the link to read the rest- but Adam and Eve is the END of the story, not the beginning. I've been fond of saying that homosexuality denies 6000 years of human history and research into marriage, and while that is true, I think I'm now going to change it to say that homosexuality denies 385 million years of evolution.
