Every day, hundreds of observations and experiments pour into the hopper of the scientific literature. Many of them don't have much to do with evolution - they're observations about the details of physiology, biochemistry, development, and so on - but many of them do. And every fact that has something to do with evolution confirms its truth. Every fossil that we find, every DNA molecule that we sequence, every organ system that we dissect, supports the idea that species evolved from common ancestors. Despite innumerable possible observations that could prove evolution untrue, we don't have a single one. We don't find mammals in Precambrian rocks, humans in the same layers as dinosaurs, or any other fossils out of evolutionary order. DNA sequencing supports the evolutionary relationships of species originally deduced from the fossil record. And, as natural selection predicts, we find no species with adaptations that only benefit a different species. We do find dead genes and vestigial organs, incomprehensible under the idea of special creation. Despite a million chances to be wrong, evolution always comes up right. That is as close as we can get to a scientific truth.
Consider yourself and the cello. As you play the music moves out to the listener, and also enters the core of your own being, for somehow you are tuned to the cello. Well, I am persuaded that this is because you are a chord. I am a chord. Our DNA dictates our physicality-made up of billions of little notes-on a basic level. Add to that our geography, background et cetera, and you have your original score. Life is the layering of chords, but the underlying one that we are will never change. This brings us to string theory and love. Our personal chord resonates with the personal ones of others, and sometimes we encounter another person who is completely harmonious with us. It is a dominant, overwhelming attraction on the DNA level. However, such a person can appear to be our opposite-and that's where this 'opposites attract' notion comes from-because they have tuned their chord in a different way. In reality, we are attracted to the person we have chosen not to become, an alternative adjustment to a chord that is nearly the same as our own. The clashing portions of the chords sounding together advance the richness of it. So when you make love you aren't expressing emotions or showing affection, you are merging melodies. You are players in the same symphony.
