To this nature/nurture debate, I would like to contribute with a metaphor.
To me, the relation between nature and nurture can be seen clearly in an
example like the "absolute pitch".  Perfect Pitch is something you are born
with, still a person with Perfect Pitch doesn't inherit the tones, just the
ability to remember them.  Hence, this person must "record" the tones in
his brain to be able to recognize them, in the future.

It is like pouring water in a jar, where the water is the nurture and the
jar the genetic coding; The water is needed to fill up the jar, but the
water cannot take any other form than the jar allow it to.
