&gt; What advantages did the Neanderthal genes add (or take away)? The only way to really find out is to create a modern day living Neanderthal. There&#x27;s probably decades of research to do before we can pull that off, but some day it will happen<p>Do you want to create Khan? Because that is how you create Khan. If you&#x27;re averaging a bunch of genomes to do this (e.g simple rank-based voting), and assuming most mutations are deleterious, you&#x27;re probably going to end up with some sort of super-Neanderthal who is way smarter and stronger than the average human.
