I think environmental factors play a huge part. Of course when dealing with now Billions of people we will see untold numbers of Variations. But IMHO back in the early days we were a product of our environment and available Nutritional factors. One could possibly argue the reason "Modern-Man Homo-Sapiens" were smarter than the older lines is because of Coastal migration and the intake of seafood. Fish = Brain food. There is no evidence of those other older lines eating seafood YET.

So if we went back in time, these ancient people would be able to instantaneously understand English, Russian, Arabic, Cantonese, Japanese & Finnish. Somehow I don't think so.
If these people were so advanced, then where's all their advanced technology? All I'm seeing is the typical conspiracy theories from people with wild imaginations and no evidence to back it up.
Some knowledge has obviously been forgotten, but that doesn't make them more advanced or more intelligent than modern man. When silly conspiracy theorists rant & rave that modern man couldn't build pyramids, they are talking complete nonsense. Of cource we could,
One thing is for sure, our ancient ancestors couldn't build sky scrapers, or split the atom, as they simply weren't smart enough.
If an advanced culture, comparable in technology & knowledge to modern man existed in the distant past, then it must of been one hell of a cataclysm to remove all traces of it. Because that's something even the recent earthquakes and tsunami in Japan couldn't do.

Good to see you back. Something from my way.
This could be why there is such a diverse spectrum in eye and hair color, not to mention physical build, appearance and height among modern humans. How about this for a possible scenario. As modern man left Africa in his great migration he swapped DNA with those potentially older lines.
Generation after generation of breeding amongst themselves as the "Newer lines" of nomadic herdsmen traversed back and forth across the great Eurasian continent. Maybe why the Australian Aboriginals and others in the region look very "Africanized" Is it possible that a second or third exodus out of Africa such as Coastal Migration occurred that bypassed a mixture of some of the more Northern older lineages? I think so.
DNA evidence linking Indian tribes to Australian Aboriginal people supports the theory humans arrived in Australia from Africa via a southern coastal route through India, say researchers. The research, lead by Dr Raghavendra Rao from the Anthropological Survey of India, is published in the current edition of BMC Evolutionary Biology.
One theory is that modern humans arrived in Australia via an inland route through central Asia but Rao says most scientists believe modern humans arrived via the coast of South Asia. Skeletal remains, dating back between 40-60,000 years from Lake Mungo in New South Wales, also support the theory that modern human arrived in Australia at least as far back as this, he says.
