Max Planck Institute recent finding concludes that humans who live outside of Africa have 1-4% of Neanderthal DNA and that those who live in Africa are 100% from Homo-sapiens.
Things seems to be a little clearer now, this is how I see it:-
It all makes sense when you consider that the genome difference between humans and chimpanzees were found to be around 1% and then later revised 10x to around 10%.
Basically humans vary so much in skin colour and body traits all around the world. For such a configuration to happen there should have been 'extremes' and then a blend among these 'extremes'. Think of it like a black & white TV set. It displays black, white and different shades of grey.
On one hand you have the Neanderthal in the icy european north with bright blue eyes, fair skin and straight hair and on the other hand you have the Homo-sapiens in hot central Africa with dark eyes, black skin and coiled hair. Then at some point in time the two species co-existed at a converging area most probably the middle-east, they interbred to give birth to the early human explorers.
The new breeds explored different parts of the world at different time intervals (10,000 years) and their respective climate sculptured what we now know as babylonians, persians, indians, chinese or even aboriginal Australians. My guess is the further north the region is, the greater the Neanderthal DNA content. Therefore I would say that Europe & Russia have a 4% Neanderthal DNA content, Mongolia & China 3%, India 2%, Australian Aboriginal 1%, Africa & Madagascar 0%.
Note the skin colour variation from white in Europe & Russia (4%) to black in Aboriginal Australia (1%). Perhaps our skin colour is determined within the 4% Neanderthal DNA that we may have. 4% is huge compared to the initially thought 1% DNA difference between human and chimps.
Note: Im no scientist, the above is just the big picture as i see it with all the possible inaccuracies.

My words on the iPad
Everyone has his views on Apple's iPad, here is mine:-
iPad is yet another luxury gear whose success relies on how close it is to itself. It will surely and brilliantly suit all people non-techie needs and will make BUYING anything as easy as possible (That's the only revolution here). So everything will be possible with the iPad, if the solution is not available for free, you just buy the app/song/book/magazines/concert tickets whatever. This closed model is of course very appealing to all businesses and hence adopted by all.
All the frenzy around the iPad looks very promising, which means that the IT sector still has its golden years ahead.
The ban on Adobe's Flash is purely a business decision which affects directly the web landscape and that's why all the photos i posted on the blog won't appear on the iPad. Thats lame but i wonder for how long will Apple resist when new competitors are entering the couchpad market with Flash enabled.
Bottom-line I already have the smaller iPod Touch which fit perfectly in my jean back pocket, i will not buy a bigger iPad but i will not refuse an iPad as a gift either.. (Note: I don't read books and when i surf the web I have 80 tabs open in my browser) What I will buy are some Apple shares if I can get the money ;) and some Android-based devices which look more open and versatile yet promising.
