DDoS attacks

What would happen if you combined Moore’s law with Darwin’s Theory of Evolution and applied them to DDoS attacks?  Unfortunately, modern DDoS attacks seem to embody this idea perfectly as both the frequency and complexity of these attacks have become truly staggering in just a short amount of time.
