Sexual reproduction ought to be a recipe for evolutionary disaster. It's a waste of resources producing no short-term advantages. It demands an entirely different form of cell division and requires highly designed interconnected components to succeed. And yet, sex reigns supreme in the biological world.

This is Part 1 of 3.
