I suspect that the taboo springs from the "curse" that is the very real situation of increased birth defects and hereditary disease in children from parents who are closely related. And that brings up the tough question of where does society draw the line in taking care of children who can't take care of themselves?
It's relatively easy to ban incest, but it is not so easy to take care of a child with a severe disability for life. Not that ease is the standard by which we should judge these questions, I'm just rambling. I think that your distaste for incest is culturally instilled, but it could be innate. We typically find people with very different markers on their cells (MHC) more attractive, and we recognize those people by their pheromones. Mammals other than humans appear to select mates in a way similar to this.
Thinking about this young couple who have fallen in love....we all tend to "fall in love" with people who have the characteristics of our early caregivers, it is programmed into us at age 0-2. So these two both had the same mother, same early care, and so their attraction at that level is probably extremely strong. The fact that they did not grow up together eliminated the usual sibling interactions that seem to stop most people from wanting to sex their siblings....
