One of the key skills of design thinkers is to Cross Pollinate/ draw insights from various disciplines & comeup with Innovative ideas. Ideo calls its people to be T shaped people, who enjoy a breadth of knowledge in many fields but also have depth in atleast one area of expertise. One of the benefits what I have felt working with these kind of people is that they seem to look at a problem from various perpectives at the same time draw insights from various unrelated fields. They think in metaphors & see relationships across disciplines.
Janine Benyus recently gave a talk at TED Global about Biomimicry in action by highlighting various examples about what we can learn from nature in solving design problems.
