Last night I watched interesting documentary titled "The Journey of Man: A Genetic Odyssey" made by book by Dr.Spencer Wells - the book was published in 2002. and documentary filmed very next year,its actually good thought it did not convince me completely.
According to Dr.Wells who had been researching genetics for a decade (together with others,it was a team work) we can track our ancestors by following blood analysis of the Y chromosome. Its very interesting theory and I do believe that our blood hides secrets of our history, in fact Graham Hancock had proposed that we should not look for outside aliens and universe but inside of our DNA for messages about our past and possible place of origins. Hancock is unfortunately not recognized in academic circles (though his theories have lots of followers around the world,thanks to his best selling books like "Supernatural" that I have already reviewed here) and Dr.Wells belongs to scientific school that bases its theories on proven medical research.
And medical research says we can trace paths of our ancestors all the way down to South Africa - according to Dr.Wells,group of early humans very similar to today's San people (the ones who talk with click sounds) left Africa probably following wild animals who were leaving for greener pastures, walked following Middle East and Asian coast and end up in today's Australia. Another groups separated and went into central Asia and later ice-covered Europe where their skin,pigmentation and even body form changed according to new climatic surroundings. In a documentary Dr.Wells himself travels around the world and follows exactly same paths that he is talking about - he even tries to explain to people in remote places about his work but I don't really believe they understood what he was talking about,after all this is enthusiastic genetic researcher talking to people in skin covered huts in the middle of nowhere. The most interesting part of the movie brings Dr.Wells in frozen northern part of Asia where he finds nomadic Chukchi people who live in constant winter herding reindeers and completely cut from the rest of the world - he believes it was people like Chukchi who crossed than frozen Bering Sea and later populated North and South America. He talks to Native American Navajo people who are polite enough to accept his theory but they still treasure their own legends about birth from earth. Very end of documentary brings Dr.Wells to Brazil which is complete mix of different races and he points that in the future it would be very difficult to do genetic research like this, because the notions of race will eventually disappear. The movie ends with sympathetic feeling towards human race being connected like some big family, feel good end, we are all related.
My own opinion - and here I go against scientists,genetic research and chromosomes - is that I don't see any reason why should we be so sure about early humans slowly populating earth, instead of having them living simultaneously in different continents. Just like you have fishes, birds and plants in different variations everywhere around the world I believe early humans simply lived in different continents and yes,they all have similar chromosomes because they all belong to the same category of humanoids. In animal world, chimpanzees and gorillas are our closest relatives and the difference in chromosomes are staggeringly small - take few bits and pieces and we are almost the same being. This is why I go for Graham Hancock's theory that in the future, blood research will prove that at certain point artificial genetic experiments had radically improved the size of early humanoids brain and thanks to "outside help" we became masters of the planet. The message is inside of us, in our blood and not outside in the sky. The God (as creator) is inside of us. Hancock writes very interestingly about drug-related experiments where people experienced "conversations" with our makers, thanks to DNA messages saved in our blood. I go for Hancock anytime.
