The one thing that defines us all!

The one thing that is common to all people, no matter where they are coming from or how they see the world is the gene structure that defines each and every one of us. Due to our genes we are always defined as humans. But what makes humans human? An ordinary answer to that question would be manifold and include our ability to think, to talk and to reason. Our ability to produce things for use but also for pleasure, like music, make us human and in this regard great musicians, like Beethoven, Bach, or Mozart are even more human than certainly I ever will be. But there is another sense to this question.
