I think this finding is interesting in the light of the latest and fast growing body of experimental results in neuroscience; finding correlation (some are straight forward, and not very complex) of so called unique attributes to genetics and physiology. this might carry with it a fundamental perceptual change. first we learned that the earth is not the center, than we realized that the human emergence is part of a bigger continuum (evolution that is) and now we come to know that one own psyche is not unique...

... but you are free to apply your psyche in unique ways ... or so at least I hope k
