I've grown up and went through school with a "politically correct" view on people that we are all "the same". The TED talk that I've listed below hints that this view might've arisen in the post-WW2 world.
Now, as I'm looking at the real life, read about neuroscience and listen to talks like this one Juan Enriquez: Will our kids be a different species, I'm starting to realize that humans are not all the same, and are instead quite different.
My question is: how different are humans from each other from a point of view of neuroscience and neurobiology?
One of the talks at TED.com gave a number that Homo Sapiens is 0.004% different from Neanderthal genetically. Another example given that olympic powerlifters have a certain genetic marker that the general population might not have.
To refine the question: just how different from a pure "hardware" point of view( our brains/genetic structure) are humans of the same haplogroup from one another?
