The headline suggests the article will provide an answer. It does not. Rather, the article discusses the many complex problems that lie between us and being able to ask meaningful questions that might one day provide us with an answer, questions of genetics (we are very similar to chimps), cognition (other animals can do many of the things we do), culture (many other animals have culture), and brain structure (not much unique to our brain). For all of the parenthetical comments, one might add: At least at the scales we are currently capable of measuring, at least given current understanding of these terms, etc. tl;dr? We do not know what makes us unique. If anything.
