I was more giving you shit for your spelling and grammar, lol. But, now you have me thinking! Skull structure is definitely different when comparing homo sapiens and neanderthals, etc. But you seem to be correct as there are minor genetic variations between the races that exist today that aid in forensic identification. If interested, this article popped up and seems concise and intelligent. (The other initial article was from Slate, so I ignored that one, haha)
