May I talk to your inner chimp?

Taken from Nature Newsfeature 29/01/2009: "much of a person’s everyday life is determined not by their conscious intentions and deliberate choices, but by mental processes put into motion by their environment" [...] "humans lived in social groups long before language evolved, and the language function presumably exists on top of a more archaic brain system for non-linguistic social signalling."
So despite our sophisticated linguistic communication, it's still our inner chimp that rules our world. Of course we're clever enough to exploit this knowledge to "improve sales success by as much as 20 %". 20 % more of things we neither want nor need, now that's fantastic progress; congratulation, Homo!
